Question

我正在尝试实施搜索。我正在使用搜索视图元素，并使用工具栏和应用程序栏布局实现自定义操作栏。我还在主要活动中将搜索视图和searchable关联在一起。这是我的代码

搜索xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.v7.widget.SearchView
        android:id="@+id/searchview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end" />

</Frame Layout>

活动主xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <include layout="@layout/search" />

        </android.support.v7.widget.Toolbar>

    </android.support.design.widget.AppBarLayout>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:text="Hello World!" />

</Linear Layout>

清单

<activity
            android:name=".MainActivity"
            android:theme="@style/AppTheme.NoActionBar">
            <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=".SearchResultsActivity" />
        </activity>
        <activity
            android:name=".SearchResultsActivity"
            android:theme="@style/AppTheme.NoActionBar"
android:parentActivityName=".MainActivity" >
            <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value=".MainActivity" />
            <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" />
        </activity>

mainactivity.java

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        SearchView searchView = (SearchView) findViewById(R.id.searchview);
        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        searchView.setSearchableInfo(manager.getSearchableInfo(getComponentName()));

搜索结果activity.java

Text View text View;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search_results);

        handleIntent(getIntent());
        textView = (TextView) findViewById(R.id.textview);
    }

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

    private void handleIntent(Intent intent) {

        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            String query = intent.getStringExtra(SearchManager.QUERY);
            textView.setText(query);
        }
    }

搜索活动未打开。我要去哪里错了？
