android：获取已单击项目的搜索建议文本

我使用的是官方Android示例代码，它为我们提供了一个搜索界面，您可以在其中搜索一个单词，当用户键入时，建议将显示在下拉列表视图中

单击搜索建议时，将向您的可搜索活动发送意图。此意图的操作字段通过可搜索XML进行描述，如下所示：

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

我的问题是，我的NEWACTIVITY需要一个id来显示相关数据。我可以通过获取所单击项目的文本（就像我们使用

getItemAtPosition（pos）；

）获取该id）[字符串值]。我怎么得到它？

我做到了

Cursor cursor = managedQuery(intent.getData(), null, null, null, null);
cursor.moveToFirst();
String y = cursor.getString(1).trim();
final int x = Integer.valueOf(y) - 1;
myIntent.putExtra("id", y);

我认为，当用户点击建议时，获取字符串查询的一种安全方法是，在搜索时，从intent android自动传递查询

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    // 1. Handle the intent on activity startup
    handleIntent(getIntent());
}

/**
* This method is necessary if you set android:launchMode="singleTop"
* in your activity Manifest. See the explanation below about singleTop.
* @param query : string the user searched for.
*/ 
@Override
protected void onNewIntent(Intent intent) {
    setIntent(intent);
    handleIntent(intent);
}

private void handleIntent(Intent intent) {

    // ------------------------------------------------------
    //                     ANSWER IS HERE
    // ------------------------------------------------------
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {

        // This will get the String from the clicked suggestion
        String query = intent.getStringExtra(SearchManager.QUERY);
        displaySearchResults(query);
    }
}

/**
* 1. Dismiss the KeyBoard and the SearchView (searchMenuItem.collapseActionView();)
* 2. Switch the container to another fragment;
* 3. Send the query to this new fragment;
*/
private void displaySearchResults(String query) {
    dismissKeyBoardAndSearchView();

    // Open SearchShowFragment and display the results
    SearchShowFragment searchShowFragment = new SearchShowFragment();
    Bundle bundle = new Bundle();
    bundle.putString(SearchShowFragment.QUERY, query);
    searchShowFragment.setArguments(bundle);
    switchToFragment(searchShowFragment);
}

建议在活动清单中设置singleTop。因为，如果用户进行多次搜索，一次接着一次，将阻止系统多次创建活动，一次在另一次的顶部。假设用户进行了10次搜索，然后开始按后退按钮，它将返回所有10个令人不安的步骤，以达到开始

<activity android:name=".MainActivity"
        android:launchMode="singleTop">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <action android:name="android.intent.action.SEARCH" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />
    </activity>

快乐编码

这是来自谷歌官方文档：

intent.getData（）中有什么内容？我不知道，它就在示例项目中。它是否包含所单击项目的值？如果是，那么如何从中提取字符串？我想要的是这样的东西：最终字符串y=（string）txtnum.getText（）；最终整数x=整数（y）-1的值；myIntent.putExtra（“iid”，x）；顺便说一句，您应该真正调用getContentResolver（）.query（），它以更简单的方式查询您的内容提供者

<activity android:name=".MainActivity"
        android:launchMode="singleTop">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <action android:name="android.intent.action.SEARCH" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />
    </activity>

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflates the options menu from XML
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.options_menu, menu);

    // Get the SearchView and set the searchable configuration
    final SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    searchMenuItem = menu.findItem(R.id.menu_search);
    searchView = (SearchView) searchMenuItem.getActionView();
    // Assumes the current activity is the searchable activity
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    searchView.setQueryRefinementEnabled(true);

    // -----------------------------------------------------------------------
    //                             Typing a Query
    // -----------------------------------------------------------------------
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {

            // Save the query to display recent queries
            SearchRecentSuggestions suggestions = new SearchRecentSuggestions(MainActivity.this,
                    MySuggestionProvider.AUTHORITY, MySuggestionProvider.MODE);
            suggestions.saveRecentQuery(query, null);
            // To protect the user's privacy you should always provide a way to clear his search history.
            // Put in the menu a way that he can clear the history with the following line below.
            /*suggestions.clearHistory();*/

            // Display the results
            displaySearchResults(query);

            return true;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            return false;
        }
    });

    return super.onCreateOptionsMenu(menu);
}
