Intent 未在 android 搜索视图中触发

Question

这是我的 searchview 代码 android.Search 选项在 toolbar 上可见，但是当输入和搜索文本时它不会触发 SearchActivity。

xml/searchable.xml

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/label"
    android:hint="@string/search" >
</searchable>

menu/menu.xml

<item android:id="@+id/search"
    android:title="@string/search_title"
    android:icon="@drawable/ic_search"
    app:showAsAction="collapseActionView|ifRoom"
    app:actionViewClass="android.support.v7.widget.SearchView" />
</menu>

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    MenuInflater inflater = getMenuInflater();
    // Inflate menu to add items to action bar if it is present.
    inflater.inflate(R.menu.menu, menu);
    // Associate searchable configuration with the SearchView
    SearchManager searchManager =
            (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView =

    searchView.setSearchableInfo(
            searchManager.getSearchableInfo(getComponentName()));

@Override

    handleIntent(intent);
}

private void handleIntent(Intent intent) {

    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        String query = intent.getStringExtra(SearchManager.QUERY);
        //use the query to search
    }
 }
}

Answer 1

尝试使用来自调用 activity 的相同 activity 名称，您使用 SearchActivity 显示搜索结果，尝试使用相同的 activity 名称

<activity android:name=".MainActivity">
          <intent-filter>
             <action android:name="android.intent.action.MAIN" />
             <category android:name="android.intent.category.LAUNCHER" />

          </intent-filter>
            <meta-data
              android:name="android.app.default_searchable"
              android:value=".SearchActivity" />
</activity>

Answer 2

您的 Activity 名为 SearchActivity，但您在清单中声明了 SearchResultsActivity：

<meta-data
     android:name="android.app.default_searchable"
     android:value=".SearchResultsActivity" />

来自docs：

To declare the searchable activity for an activity's search dialog, add a element inside the respective activity's element. The element must include the android:value attribute that specifies the searchable activity's class name and the android:name attribute with a value of "android.app.default_searchable".

Answer 3

您也可以通过编程方式执行此操作。

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) { // this is triggered when you press the key search from keyboard.
            return true;
        }

        @Override
        public boolean onQueryTextChange(String newText) { // this is triggered when you change your search text. 
            return true;
        }
    });
