我已经设置了可搜索的配置,但现在我遇到了奇怪的问题。当我提交搜索查询时,SearchActivity.class会启动一秒钟,然后返回MainActivity.class。我不知道,会发生什么。
查看我的代码:
在MainActivity:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
MenuItem searchItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);
if (null != mSearchView )
{
mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
}
SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener()
{
public boolean onQueryTextChange(String newText)
{
return true;
}
public boolean onQueryTextSubmit(String query)
{
String said = query.toString();
Log.v(said, "submited");
Intent intent = new Intent(getApplicationContext(), SearchActivity.class);
intent.setAction(Intent.ACTION_SEARCH);
intent.putExtra("query", query);
startActivity(intent);
return true;
}
};
mSearchView.setOnQueryTextListener(queryTextListener);
return super.onCreateOptionsMenu(menu);
}
安卓清单:
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.animalist.MainActivity"
android:label="@string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="@xml/searchable" />
</activity>
<activity

android:label="@string/title_activity_more"
android:launchMode="singleTop"
android:parentActivityName="com.example.animalist.MainActivity"
android:screenOrientation="portrait" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.animalist.MainActivity" />
</activity>
<activity
android:name="com.example.animalist.SearchActivity"
android:label="@string/title_activity_search"
android:launchMode="singleTop"

android:screenOrientation="portrait" >
<meta-data

android:value="com.example.animalist.MainActivity" />
</activity>
</application>
我究竟做错了什么?
