如何處理點擊搜索建議項目

我用officical的Android示例代碼「SearchableDictionary」（鏈接：http://jayxie.com/mirrors/android-sdk/resources/samples/SearchableDictionary/index.html），這給了我們一個搜索界面，在這裏你可以搜索一個詞，你有2種選擇：如何處理點擊搜索建議項目

1-放入您的關鍵字並點擊搜索圖標（鍵盤），這樣就會出現所有匹配結果的列表視圖。你點擊ListView中的一個單詞來檢索定義。

2-每當searchView關鍵字發生變化時，將您的關鍵字和建議的一個小列表自動出現，因此您可以點擊一個建議來檢索她的定義。

這是您在單擊大列表視圖中的項目時調用的搜索功能的代碼，而不是在建議列表中。

 private void doSearch(String queryStr) { 
      // get a Cursor, prepare the ListAdapter and set it 
    final DataBaseHelper myDbHelper = new DataBaseHelper(this); 
    myDbHelper.openDataBase(); 
    Cursor cursor = managedQuery(DictionaryProvider.CONTENT_URI, null, null, 
      new String[] {queryStr}, null); 
    //Cursor cursor = myDbHelper.fetchListItems(queryStr); 
    //cursorr.moveToFirst(); // moves the cursor to the first row in the result set, returns false if the result set is empty. 

    startManagingCursor(cursor); /* Managing cursors take care of closing the cursor when 
    the activity is destroyed, but they do more than that as well: they will be 
    deactivated and required as the activities is stopped and restarted. */ 

    // set the custom list adapter 
    // setListAdapter(new MyListAdapter(this, cursor)); 

    // Specify the columns we want to display in the result 
    String[] from = new String[] { DataBaseHelper.KEY_WORD, 
            DataBaseHelper.KEY_DEFINITION }; 

    // Specify the corresponding layout elements where we want the columns to go 
    int[] to = new int[] { R.id.title, 
          R.id.details }; 

    // Create a simple cursor adapter for the definitions and apply them to the ListView 
    SimpleCursorAdapter words = new SimpleCursorAdapter(this, 
            R.layout.list_item_with_description, cursor, from, to); 
    final ListView mListView = (ListView) findViewById(R.id.list); 
    mListView.setAdapter(words); 
    // search_keyword = queryStr ; 

    // Define the on-click listener for the list items 
    mListView.setOnItemClickListener(new OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 


      // Build the Intent used to open WordActivity with a specific word Uri 
      Intent wordIntent = new Intent(getApplicationContext(), DefinitionActivity.class); 
      // final Bundle bundle = new Bundle(); 


      Uri data = Uri.withAppendedPath(DictionaryProvider.CONTENT_URI, 
              String.valueOf(id)); 


      Log.d(TAG,"clicked row id="+id); 

      wordIntent.setData(data); 
      wordIntent.putExtra("clicked_item_id",id); 

      startActivity(wordIntent); 
     } 
    });

正如你可以看到，我們可以處理的項目點擊在匹配的單詞列表，但如何處理在建議小名單點擊的建議？我想捕捉點擊的建議的id，而不是大列表視圖中的點擊項目。我怎樣才能做到這一點？

當點擊搜索建議時，意向被髮送到您的可搜索活動。你可以簡單地通過配置的Android定義此意向，雖然你的搜索XML的行動領域：searchSuggestIntentAction屬性是這樣的：

<searchable 
... 
    android:searchSuggestIntentAction = "android.intent.action.VIEW">

，然後在你的搜索活動：

Intent intent = getIntent(); 
if (Intent.ACTION_VIEW.equals(intent.getAction()) { 
    //a suggestion was clicked... do something about it... 
}
