Android的搜索是永远不会调用

本文介绍了Android的搜索是永远不会调用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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Andr​​oidManifest.xml ：

<?xml version="1.0" encoding="utf-8"?> <manifest package="org.homphysiology.lists" android:versionCode="1" android:versionName="1.0" xmlns:android="schemas.android/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="schamas.android/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 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="schamas.android/apk/res/android"

应该是：

<searchable xmlns:android="schemas.android/apk/res/android"
