精彩继续~~~前面介绍了 ，到了主页面后面我们按照主页面中从上到下的顺序来接着介绍，在这里就来看SearchActivity的实现。

                                                               

（一）首先我们先根据布局文件来分析下整个页面的布局：布局文件search.xml

 第一个LinearLayout是页面最上面的search输入框search按钮。紧接着是一个手势视图内嵌套了一个FixedViewFlipper用来显示查询之前的提示、查询成功后的结果（ListView）和查询不到结果的文字提示。最后一个还是一个LinearLayout中的一个Spinner用来显示查询方式的下拉列表。

（二）SearchActivity

首先给出源码方便大家学习：

1 /**  2  * Allows content searching on Jamendo services  3  *   4  * @author Lukasz Wisniewski  5  */  6 public class SearchActivity extends Activity {  7   8     enum SearchMode{  9         Artist, 10         Tag, 11         UserPlaylist, 12         UserStarredAlbums 13     }; 14  15     private Spinner mSearchSpinner; 16     private ListView mSearchListView; 17     private EditText mSearchEditText; 18     private Button mSearchButton; 19     private ViewFlipper mViewFlipper; 20     private GestureOverlayView mGestureOverlayView; 21  22     private PlaylistRemote[] mPlaylistRemotes = null; 23  24     private SearchMode mSearchMode; 25  26     /** 27      * Launch this Activity from the outside 28      * 29      * @param c context from which Activity should be started 30      */ 31     public static void launch(Context c){ 32         Intent intent = new Intent(c, SearchActivity.class); 33         c.startActivity(intent); 34     } 35  36     /** Called when the activity is first created. */ 37     @Override 38     public void onCreate(Bundle savedInstanceState) { 39         super.onCreate(savedInstanceState); 40         requestWindowFeature(Window.FEATURE_NO_TITLE); 41         setContentView(R.layout.search); 42  43         mSearchSpinner = (Spinner)findViewById(R.id.SearchSpinner); 44         ArrayAdapter adapter = ArrayAdapter.createFromResource( 45                 this, R.array.search_modes, android.R.layout.simple_spinner_item); 46         adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 47         mSearchSpinner.setAdapter(adapter); 48  49         mSearchButton = (Button)findViewById(R.id.SearchButton); 50         mSearchButton.setOnClickListener(mSearchButtonListener); 51  52         mSearchEditText = (EditText)findViewById(R.id.SearchEditText); 53         mSearchListView = (ListView)findViewById(R.id.SearchListView); 54  55         mViewFlipper = (ViewFlipper)findViewById(R.id.SearchViewFlipper); 56         if(mSearchListView.getCount() == 0){ 57             mViewFlipper.setDisplayedChild(2); // search list hint 58         } 59  60         mGestureOverlayView = (GestureOverlayView) findViewById(R.id.gestures); 61         mGestureOverlayView.addOnGesturePerformedListener(JamendoApplication 62                 .getInstance().getPlayerGestureHandler()); 63     } 64  65     @Override 66     protected void onResume() { 67         super.onResume(); 68         boolean gesturesEnabled = PreferenceManager.getDefaultSharedPreferences(this).getBoolean("gestures", true); 69         mGestureOverlayView.setEnabled(gesturesEnabled); 70     } 71  72     @SuppressWarnings("unchecked") 73     @Override 74     protected void onRestoreInstanceState(Bundle savedInstanceState) { 75         mSearchMode = (SearchMode) savedInstanceState.getSerializable("mode"); 76         if(mSearchMode != null){ 77             if(mSearchMode.equals(SearchMode.Artist)  78                     || mSearchMode.equals(SearchMode.Tag) 79                     || mSearchMode.equals(SearchMode.UserStarredAlbums)){ 80                 AlbumAdapter adapter = new AlbumAdapter(this); 81                 adapter.setList((ArrayList

一、首先还是看onCreate方法：

1 /** Called when the activity is first created. */ 2     @Override 3     public void onCreate(Bundle savedInstanceState) { 4         super.onCreate(savedInstanceState); 5         requestWindowFeature(Window.FEATURE_NO_TITLE); 6         setContentView(R.layout.search); 7  8         mSearchSpinner = (Spinner)findViewById(R.id.SearchSpinner); 9         ArrayAdapter adapter = ArrayAdapter.createFromResource(10                 this, R.array.search_modes, android.R.layout.simple_spinner_item);11         adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);12         mSearchSpinner.setAdapter(adapter);13 14         mSearchButton = (Button)findViewById(R.id.SearchButton);15         mSearchButton.setOnClickListener(mSearchButtonListener);16 17         mSearchEditText = (EditText)findViewById(R.id.SearchEditText);18         mSearchListView = (ListView)findViewById(R.id.SearchListView);19 20         mViewFlipper = (ViewFlipper)findViewById(R.id.SearchViewFlipper);21         if(mSearchListView.getCount() == 0){22             mViewFlipper.setDisplayedChild(2); // search list hint23         }24 25         mGestureOverlayView = (GestureOverlayView) findViewById(R.id.gestures);26         mGestureOverlayView.addOnGesturePerformedListener(JamendoApplication27                 .getInstance().getPlayerGestureHandler());28     }

oncreate中先是给SearchSpinner设置适配器，然后给SearchButton添加监听事件，最后设置GestureOverlayView的监听事件。有关gesture的请介绍移步

整个方法都很简单明了，这是SearchActiviy主要功能肯定是search所以重点就落在了SearchButton的onclick事件上。下面我们来看mSearchButtonListener：

1 private OnClickListener mSearchButtonListener = new OnClickListener(){ 2  3         @Override 4         public void onClick(View v) { 5             new SearchingDialog(SearchActivity.this, 6                     R.string.searching, 7                     R.string.search_fail) 8             .execute(mSearchSpinner.getSelectedItemPosition());     9         }10 11     };

到这还没有看到真正的实现代码，onClick中只有一个SearchingDialog，继续看：

1 /**  2      * Allows cancelling search query  3      *   4      * @author Lukasz Wisniewski  5      */  6     private class SearchingDialog extends LoadingDialog
     
      {  7   8         private Integer mSearchMode;  9         private BaseAdapter mAdapter; 10  11         public SearchingDialog(Activity activity, int loadingMsg, int failMsg) { 12             super(activity, loadingMsg, failMsg); 13         } 14  15         @Override 16         public Integer doInBackground(Integer... params) { 17             mSearchMode = params[0]; 18             switch(mSearchMode){ 19             case 0: 20                 // artist search 21                 albumSearch(0);  22                 break; 23             case 1: 24                 // tag search 25                 albumSearch(1);  26                 break; 27             case 2: 28                 // playlist search 29                 playlistSearch();  30                 break; 31             case 3: 32                 // starred album search 33                 albumSearch(3);  34                 break; 35             default: 36             } 37             return mSearchMode; 38         } 39  40         @Override 41         public void doStuffWithResult(Integer result) { 42             mSearchListView.setAdapter(mAdapter); 43  44             if(mSearchListView.getCount() > 0){ 45                 mViewFlipper.setDisplayedChild(0); // display results 46             } else { 47                 mViewFlipper.setDisplayedChild(1); // display no results message 48             } 49  50             // results are albums 51             if(mSearchMode.equals(0) || mSearchMode.equals(1) ||  mSearchMode.equals(3)){ 52                 mSearchListView.setOnItemClickListener(mAlbumClickListener); 53             } 54  55             // results are playlists 56             if(mSearchMode.equals(2)){ 57                 mSearchListView.setOnItemClickListener(mPlaylistClickListener); 58             } 59         } 60  61         private void albumSearch(int id){ 62             JamendoGet2Api service = new JamendoGet2ApiImpl(); 63             String query = mSearchEditText.getText().toString(); 64             Album[] albums = null; 65             try { 66                 switch (id) { 67                 case 0: 68                     albums = service.searchForAlbumsByArtist(query); 69                     SearchActivity.this.mSearchMode = SearchMode.Artist; 70                     break; 71                 case 1: 72                     albums = service.searchForAlbumsByTag(query); 73                     SearchActivity.this.mSearchMode = SearchMode.Tag; 74                     break; 75                 case 3: 76                     albums = service.getUserStarredAlbums(query); 77                     SearchActivity.this.mSearchMode = SearchMode.UserStarredAlbums; 78                     break; 79  80                 default: 81                     return; 82                 } 83  84                 AlbumAdapter albumAdapter = new AlbumAdapter(SearchActivity.this);  85                 albumAdapter.setList(albums); 86                 albumAdapter.setListView(mSearchListView); 87                 mAdapter = albumAdapter; 88  89             } catch (JSONException e) { 90                 e.printStackTrace(); 91             } catch (WSError e) { 92                 publishProgress(e); 93                 this.cancel(true); 94             } 95         } 96  97         private void playlistSearch(){ 98             JamendoGet2Api service = new JamendoGet2ApiImpl(); 99             String user = mSearchEditText.getText().toString();100             try {101                 mPlaylistRemotes = service.getUserPlaylist(user);102                 if(mPlaylistRemotes != null){103                     PlaylistRemoteAdapter purpleAdapter = new PlaylistRemoteAdapter(SearchActivity.this);                104                     purpleAdapter.setList(mPlaylistRemotes);105                     mAdapter = purpleAdapter;106                     SearchActivity.this.mSearchMode = SearchMode.UserPlaylist;107                 }108 109             } catch (JSONException e) {110                 e.printStackTrace();111             } catch (WSError e) {112                 publishProgress(e);113                 this.cancel(true);114             }115         }116 117     }
     

好长一段代码。。。。看来是顺藤摸到瓜了，这就是整个SearchActivity中真正实现search过程的地方。

SearchingDialog这个内部类继承了LoadingDialog
    
     ，关于LoadingDialog在上一篇博客中涉及到了这里就不赘述了，想看的可以移步 。
    

1. 首先看doInBackground(Integer... params)，主要是根据获取searchSpinner选中的searchMode来调用不同search方法，mSearchMode = params[0];中的params[0]是调用在这个内部类的execute方法传进来的mSearchSpinner.getSelectedItemPosition()。其中涉及到了两个方法，albumSearch()和playlistSearch()。两个方法实现方法大体一样在这就以albumSearch为例分析下：

首先看albumSearch()：

1 private void albumSearch(int id){ 2             JamendoGet2Api service = new JamendoGet2ApiImpl(); 3             String query = mSearchEditText.getText().toString(); 4             Album[] albums = null; 5             try { 6                 switch (id) { 7                 case 0: 8                     albums = service.searchForAlbumsByArtist(query); 9                     SearchActivity.this.mSearchMode = SearchMode.Artist;10                     break;11                 case 1:12                     albums = service.searchForAlbumsByTag(query);13                     SearchActivity.this.mSearchMode = SearchMode.Tag;14                     break;15                 case 3:16                     albums = service.getUserStarredAlbums(query);17                     SearchActivity.this.mSearchMode = SearchMode.UserStarredAlbums;18                     break;19 20                 default:21                     return;22                 }23 24                 AlbumAdapter albumAdapter = new AlbumAdapter(SearchActivity.this); 25                 albumAdapter.setList(albums);26                 albumAdapter.setListView(mSearchListView);27                 mAdapter = albumAdapter;28 29             } catch (JSONException e) {30                 e.printStackTrace();31             } catch (WSError e) {32                 publishProgress(e);33                 this.cancel(true);34             }35         }

 

首先是JamendoGet2Api service = new JamendoGet2ApiImpl();获得从读取服务器的封装api，这里先不讨论api。然后根据传入的id值调用不同的方法来获取相应的内容，以id=0为例albums = service.searchForAlbumsByArtist(query); SearchActivity.this.mSearchMode = SearchMode.Artist;调用api的searchForAlbumsByArtist方法根据用户输入的mSearchEditText.getText()的查询内容来从服务器读取相应的ablum。然后设置mSearchMode。最后将获得的ablum传递给适配器albumAdapter。如果数据读取过程中捕获到WSError就调用publishProgress显示在也面上并结束线程。 这里我们要看一下这个适配器AlbumAdapter的具体内容：

1 /** 2  * Adapter representing albums 3  *  4  * @author Lukasz Wisniewski 5  */ 6 public class AlbumAdapter extends ArrayListAdapter
      
        { 7      8     public AlbumAdapter(Activity context) { 9         super(context);10     }11 12     @Override13     public View getView(int position, View convertView, ViewGroup parent) {14         View row=convertView;15 16         ViewHolder holder;17 18         if (row==null) {19             LayoutInflater inflater = mContext.getLayoutInflater();20             row=inflater.inflate(R.layout.album_row, null);21 22             holder = new ViewHolder();23             holder.image = (RemoteImageView)row.findViewById(R.id.AlbumRowImageView);24             holder.albumText = (TextView)row.findViewById(R.id.AlbumRowAlbumTextView);25             holder.artistText = (TextView)row.findViewById(R.id.AlbumRowArtistTextView);26             holder.progressBar = (ProgressBar)row.findViewById(R.id.AlbumRowRatingBar);27 28             row.setTag(holder);29         }30         else{31             holder = (ViewHolder) row.getTag();32         }33         34         holder.image.setDefaultImage(R.drawable.no_cd);35         holder.image.setImageUrl(mList.get(position).getImage(),position, getListView());36         holder.albumText.setText(mList.get(position).getName());37         holder.artistText.setText(mList.get(position).getArtistName());38         holder.progressBar.setMax(10);39         holder.progressBar.setProgress((int) (mList.get(position).getRating()*10));40 41         return row;42     }43     44     /**45      * Class implementing holder pattern,46      * performance boost47      * 48      * @author Lukasz Wisniewski49      */50     static class ViewHolder {51         RemoteImageView image;52         TextView albumText;53         TextView artistText;54         ProgressBar progressBar;55     }56 }
      

AlbumAdapter继承了ArrayListAdapter（之前介绍过），主要就是实现了ArrayListAdapter中的抽象方法getView，jamendo通过基类ArrayListAdapter提供的抽象方法分离了适配器的具体实现。AlbumAdapter没什么特别的就是把获得数据显示在相应的view上。为了避免每次调用重复创建convertView，使用了ViewHolder进行缓存配合setTag提高效率，ViewHolder是listview常用的优化方法。另外其中用到了RemoteImageView，一个ImageView的扩展类具体移步 。

2. 关注doStuffWithResult(Integer result)方法，这是实现的LoadingDialog的一个抽象方法，当doInBackground方法返回值不为null时调用。

1 @Override 2         public void doStuffWithResult(Integer result) { 3             mSearchListView.setAdapter(mAdapter); 4  5             if(mSearchListView.getCount() > 0){ 6                 mViewFlipper.setDisplayedChild(0); // display results 7             } else { 8                 mViewFlipper.setDisplayedChild(1); // display no results message 9             }10 11             // results are albums12             if(mSearchMode.equals(0) || mSearchMode.equals(1) ||  mSearchMode.equals(3)){13                 mSearchListView.setOnItemClickListener(mAlbumClickListener);14             }15 16             // results are playlists17             if(mSearchMode.equals(2)){18                 mSearchListView.setOnItemClickListener(mPlaylistClickListener);19             }20         }

首先是给listview设置刚刚获取到数据的Adapter，判断listview中是否有数据，如果有mViewFlipper就显示第一个view-SearchListView，如果没有就显示第二个view-no_results。然后根据search类型不同设置相应的item点击事件。如果search的结果是albums 就设置mAlbumClickListener，如果是playlists就设置mPlaylistClickListener。简单说就是当检索结果是专辑（ablum）就设置点击事件：点击后播放该ablum，如果是播放list就设置点击事件：显示playlist的具体内容。两个监听器源码给出：

1 private OnItemClickListener mAlbumClickListener = new OnItemClickListener(){ 2  3         @Override 4         public void onItemClick(AdapterView
       adapterView, View view, int position, 5                 long time) { 6             Album album = (Album)adapterView.getItemAtPosition(position); 7             PlayerActivity.launch(SearchActivity.this, album); 8         } 9 10     };11 12     private OnItemClickListener mPlaylistClickListener = new OnItemClickListener(){13 14         @Override15         public void onItemClick(AdapterView
       adapterView, View arg1, int position,16                 long arg3) {17             PlaylistRemote playlistRemote = (PlaylistRemote) adapterView.getItemAtPosition(position);18             PlayerActivity.launch(SearchActivity.this, playlistRemote);19         }

 

二、 Search状态的保存。由于search页面是基于本search页面的activity的跳转，也就是说从search跳转后有可能会再返回search页面，为了避免在返回时因为searchActivity被kill掉而没有数据，所以有必要保存。主要实现如下：

1     @SuppressWarnings("unchecked") 2     @Override 3     protected void onRestoreInstanceState(Bundle savedInstanceState) { 4         mSearchMode = (SearchMode) savedInstanceState.getSerializable("mode"); 5         if(mSearchMode != null){ 6             if(mSearchMode.equals(SearchMode.Artist)  7                     || mSearchMode.equals(SearchMode.Tag) 8                     || mSearchMode.equals(SearchMode.UserStarredAlbums)){ 9                 AlbumAdapter adapter = new AlbumAdapter(this);10                 adapter.setList((ArrayList
     
      ) savedInstanceState.get("values"));11                 mSearchListView.setAdapter(adapter);12                 mSearchListView.setOnItemClickListener(mAlbumClickListener);13             }14             15             if(mSearchMode.equals(SearchMode.UserPlaylist)) {16                 PlaylistRemoteAdapter adapter = new PlaylistRemoteAdapter(this); 17                 adapter.setList((ArrayList
      
       ) savedInstanceState.get("values"));18                 mSearchListView.setAdapter(adapter);19                 mSearchListView.setOnItemClickListener(mPlaylistClickListener);20             }21             22             mViewFlipper.setDisplayedChild(savedInstanceState.getInt("flipper_page"));23         }24         super.onRestoreInstanceState(savedInstanceState);25     }26 27     @Override28     protected void onSaveInstanceState(Bundle outState) {29         if(mSearchMode != null){30             outState.putSerializable("mode", mSearchMode);31             if(mSearchMode.equals(SearchMode.Artist) 32                     || mSearchMode.equals(SearchMode.Tag) 33                     || mSearchMode.equals(SearchMode.UserStarredAlbums)){34                 AlbumAdapter adapter = (AlbumAdapter)mSearchListView.getAdapter();35                 outState.putSerializable("values", adapter.getList());36             }37 38             if(mSearchMode.equals(SearchMode.UserPlaylist)) {39                 PlaylistRemoteAdapter adapter = (PlaylistRemoteAdapter)mSearchListView.getAdapter();40                 outState.putSerializable("values", adapter.getList());41             }42             43             outState.putInt("flipper_page", mViewFlipper.getDisplayedChild());44         }45         super.onSaveInstanceState(outState);46     }
      
     

 

不做太多解释了，onSaveInstanceState(Bundle outState) 保存状态，onRestoreInstanceState(Bundle savedInstanceState)回复状态。

到这里SearchActivity就介绍完了，SearchActivity相对比较简单，有些内容在之前介绍过这里就没有赘述，大家可以看看以前的博客。

今天头脑有点晕，写的可能有点乱，将就这看吧。

 

休息~休息一下~~~
