Android - SearchView无法打开Activity

Question

我正在尝试使用本教程来设置SearchView:https: //developer.android.com/training/search/setup.html

我创建了一个带有SearchView的菜单并配置了SearchView.但是,单击键盘上的"搜索"按钮或SearchView的提交按钮时,我的SearchResultActivity无法打开.

我还尝试按动作栏上的搜索小部件不会触发我的搜索活动,但我无法让SearchView打开第二个活动.有人可以帮忙吗？

这是我的菜单:

<menu 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"
    tools:context="com.sample.searchbarapplication.MainActivity">
    <item
        android:id="@+id/action_search"
        android:orderInCategory="100"
        android:title="@string/action_search"
        android:icon="@drawable/ic_search_white_24dp"
        app:actionViewClass="android.support.v7.widget.SearchView"
        app:showAsAction="collapseActionView|ifRoom" />
</menu>

search-configuration 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="@string/search_hint" />

表现:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.sample.searchbarapplication">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

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

        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            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.searchable"
                android:resource="@xml/searchable" />

        </activity>

        <activity android:name=".SearchResultActivity"
            android:launchMode="singleTop">

            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
            </intent-filter>

        </activity>

    </application>

</manifest>

MainActivity在其工具栏中包含SearchView:

public class MainActivity extends AppCompatActivity {
ActionMenuView mActionMenuView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

    setSupportActionBar(toolbar);
    getSupportActionBar().setTitle(null);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);

    SearchManager searchManager =
            (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView =
            (SearchView) menu.findItem(R.id.action_search).getActionView();
    searchView.setSearchableInfo(
            searchManager.getSearchableInfo(getComponentName()));

    searchView.setIconifiedByDefault(false);
    searchView.setSubmitButtonEnabled (true);

    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    //noinspection SimplifiableIfStatement
    if (id == R.id.action_search) {
        Log.v("click","click");
    }

    return true;
}
}

和SearchResultActivity.java:

public class SearchResultActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search);
        handleIntent(getIntent());
    }

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

    private void handleIntent(Intent intent) {
        Log.v("query2","query");
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            String query = intent.getStringExtra(SearchManager.QUERY);
            //use the query to search your data somehow
            Log.v("query",query.toString());
        }
    }
}

编辑 - 这是包含SearchView的MainActivity的布局文件.include标记的内容是(空)RelativeLayout,没有子视图.

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 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:fitsSystemWindows="true"
    tools:context="com.sample.searchbarapplication.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" >

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

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

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

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

编辑2:当我带来

 <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
            </intent-filter>

在MainActivity的标签中,MainActivity在搜索时再次启动(当按下键盘中的搜索按钮或按下工具栏中的搜索结果按钮时).但我想做的是启动一个不是MainActivity的新Activity.这可能吗 ？

我的新清单看起来像这样(注意MainActivty标签中的额外意图过滤器):

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.sample.searchbarapplication">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <meta-data
            android:name="android.app.default_searchable"
            android:value=".MainActivity" />

        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            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.searchable"
                android:resource="@xml/searchable" />

            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
            </intent-filter>

        </activity>

        <activity android:name=".SearchResultActivity">

        </activity>

    </application>

</manifest>

Answer 1

这似乎是一个常见的误解，我第一次想要为搜索结果添加一个新活动时也遇到了这个问题。

在重新检查此处的文档后，我意识到“SearchableActivity”实际上是显示结果的那个。

因此，您必须为 MainActivity 更改此设置：

<activity
        android:name=".MainActivity"
        android:theme="@style/AppTheme.NoActionBar">
        <meta-data
            android:name="android.app.default_searchable"
            android:value=".SearchResultActivity"/>

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

这对于 SearchResultActivity：

<activity android:name=".SearchResultActivity">
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>

        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />
 </activity>

综上所述，“android.app.default_searchable”元标记必须位于启动搜索的 Activity 内。显示搜索的活动需要意图过滤器和可搜索的元数据。
