请不要标记为重复，因为我已经查看了其他几个相同的问题并且这些解决方案对我不起作用。

category_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/category.search"
        android:title="Search"
        app:showAsAction="ifRoom|collapseActionView"
        app:actionViewClass="android.support.v7.widget.SearchView"/>
</menu>

Mainfest.xml

<activity android:name=".CategoryActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
                <meta-data android:name="android.app.default_searchable" android:value=".SearchResultsActivity" />
            </intent-filter>
        </activity>
        <activity
            android:name=".SearchResultsActivity"
            android:label="@string/title_activity_search_results"
            android:theme="@style/AppTheme.NoActionBar"
            android:launchMode="singleTop">
            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
            <meta-data                android:name="android.app.searchable"                android:resource="@xml/searchable" />
            <meta-data                android:name="android.support.PARENT_ACTIVITY"                android:value=".CategoryActivity" />
        </activity>

CategoryActivity.java

@Override
public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.category_menu, menu);
        SearchView searchView = (SearchView) menu.findItem(R.id.category_search).getActionView();
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, SearchResultsActivity.class)));
        return true;
}

SearchResultsActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.d(TAG,"Search Began");
    setContentView(R.layout.search_results_activity);
    handleIntent(getIntent());
}

@Override
protected void onNewIntent(Intent intent) {
    handleIntent(intent);
}

private void handleIntent(Intent intent) {
    Log.d(TAG, "Herer");
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        String query = intent.getStringExtra(SearchManager.QUERY);
        //use the query to search your data somehow
        Log.d(TAG, query);
    }
}

res/xml/下的searchable.xml

<?xml version="1.0" encoding="utf-8"?>

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/app_name"
    android:hint="Recipe Search" />

android 提示和标签必须都是“@String/...”类型的硬编码文本将阻止 SearchResultActivity 启动。

你应该onQueryTextListener在 searchView 中添加。

@Override
public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.category_menu, menu);
        SearchView searchView = (SearchView) menu.findItem(R.id.category_search).getActionView();
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, SearchResultsActivity.class)));
        searchView..setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                startActivity(CategoryActivity.this, SearchResultActivity.class);
                return true;
            }

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

如果 insearchable.xml不包含android:label，它不会启动SearchResultActivity，请确保将此代码添加到searchable.xml：

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="@string/app_name" ===================> can not contain empty strings
android:hint="Recipe Search" />
