android - 如何处理搜索建议点击项目

Question

我使用了官方 Android 示例代码“SearchableDictionary”(链接:http://jayxie.com/mirrors/android-sdk/resources/samples/SearchableDictionary/index.html)，它为我们提供了一个搜索界面，您可以在其中搜索一个词，并且有 2 个选项:

1- 输入您的关键字并单击搜索图标(键盘)，所有匹配结果的 ListView 将出现。您单击 ListView 中的单词以检索定义。

2- 输入您的关键字，每次 searchView 关键字更改时都会自动出现一个小的建议列表，因此您可以单击一个建议来检索她的定义。

这是当您点击大 ListView 中的项目时调用的搜索函数的代码，而不是建议列表中的项目。

     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);
         }
     });

如您所见，我们可以处理在匹配词列表中单击的项目，但我如何处理在小建议列表中单击的建议？我想捕捉点击建议的 ID，而不是大 ListView 中点击的项目。我该怎么做？

Answer 1

单击搜索建议时，会向您的可搜索 Activity 发送一个 Intent。您可以通过配置 android:searchSuggestIntentAction 属性，通过可搜索的 XML 简单地定义此 Intent 的 Action 字段，如下所示:

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

然后，在您的可搜索 Activity 中:

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