Android的搜索是永远不会调用 [英] Android search is never invoked
问题描述
我完全卡住，花了几个小时阅读这个可能的解决方案。
根本不能让我的搜索活动启动。
I am completely stuck and have spent hours reading possible solutions to this. Simply can't get my search activity to start.
我有一个主要活动，从中我希望搜索按钮，开始搜索活动：
I have a main activity, from which I want the search button to start a search activity:
文件 MainApp.java
public class MainApp extends Activity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainapplayout);
}
public boolean onCreateOptionsMenu(Menu m){
getMenuInflater().inflate(R.menu.mainappmenu,m);
return true;
}
public boolean onOptionsItemSelected(MenuItem m) {
if(m.getItemId()==R.id.menu_search){
return onSearchRequested(); // THIS IS CALLED, AND RETURNS TRUE
}else return false;
}
}
无论是pressing的UI按钮，也没有硬件搜索键，调用搜索。 onSearchRequested（）绝对是调用，并返回真正。
文件的AndroidManifest.xml ：
<?xml version="1.0" encoding="utf-8"?>
<manifest package="org.homphysiology.lists"
android:versionCode="1" android:versionName="1.0"
xmlns:android="http://schemas.android.com/apk/res/android">
<uses-sdk android:minSdkVersion="8" />
<application
android:name="org.homphysiology.lists.MainApp"
****REMOVED THIS LINE NOW, thanks arju, still not working tho
android:icon="@drawable/ic_launcher">
<activity android:name="org.homphysiology.lists.MainApp">
<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="org.homphysiology.lists.SearchActivity"
/>
</activity>
<activity android:name="org.homphysiology.lists.SearchActivity">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
<category android:name="android.intent.category.DEFAULT" />
****REMOVED THIS LINE NOW, thanks tushar, still not working tho
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="@xml/searchable"
/>
</activity>
</application>
</manifest>
和我有以下内容：
文件 RES / XML / searchable.xml ：
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schamas.android.com/apk/res/android"
android:label="@string/search_label"
android:hint="@string/search_hint"
/>
这些字符串是在 /res/values/strings.xml 。
搜索活动本身很简单，但从未创建 - 我在构造函数中断点：
The search activity itself is simple, but is never created - I have a breakpoint in the constructor:
文件 SearchActivity.java ：
public class SearchActivity extends ListActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setListAdapter(...)
}
}
任何人都可以发现任何问题吗？
[在Eclipse编译朱诺4.2.1 SDK 21.0.1，在HTC Desire Z的测试]
谢谢...
Can anyone spot any problem here? [compiling in eclipse Juno 4.2.1, SDK 21.0.1, testing on HTC desire Z] Thanks...
((SearchManager)getSystemService(Context.SEARCH_SERVICE))
.getSearchableInfo(getComponentName())
收益空。也许这只是敲敲打打家，我的 SearchActivity 尚未正确注册......事实
returns null. Maybe this is just hammering home the fact that my SearchActivity hasn't been registered properly...
修改@ arju的建议：我可以通过使用手动启动搜索活动
Modifying @arju's suggestion: I can start the Search activity "manually" by using
boolean onOptionsItemSelected(MenuItem m){
startActivity(new Intent(this,SearchActivity.class));
return true;
}
，但当然，这将不会与硬件按钮的工作，而且，它不显示系统搜索对话框
but of course, this won't work with the hardware button, and moreover, it doesn't display the system search dialog.
我也尝试设置搜索元数据，而不是主要活动的整个应用程序：
I have also tried setting the search metadata for the whole application as opposed to the main activity:
<manifest>
<application>
<activity ...MainApp... > ... </activity>
<activity ...SearchActivity... > ... </activity>
<meta-data
android:name="android.app.default_searchable"
android:value="org.homphysiology.lists.SearchActivity"
/>
</application>
</manifest>
同样的问题！搜索活动从不实例。
same problem! search activity is never instantiated.
推荐答案
的<一个href=\"http://developer.android.com/guide/topics/search/search-dialog.html#DeclaringSearchableActivity\"相对=nofollow> Android文档说：
请注意：在＆lt;意图滤波器>不需要＆下;类>的默认值（你通常看到上述＆lt;活性>元素），因为系统明确地提供了ACTION_SEARCH意图的搜索活动，使用它的组件名称
Note: The < intent-filter> does not need a < category> with the DEFAULT value (which you usually see in < activity> elements), because the system delivers the ACTION_SEARCH intent explicitly to your searchable activity, using its component name.
编辑：
这是这样的：
<searchable xmlns:android="http://schamas.android.com/apk/res/android"
应该是：
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
通知 schamas VS 模式：）
