搜索對話框不會TabHost實施出現

Question

我創建使用下面的示例代碼我的標籤，並在評論中有人指出，很多人再也無法在搜索對話框打電話，我已經能夠不再有我程序強制關閉，當你點擊硬件搜索按鈕，但是當你點擊按鈕，它不會再彈出任何東西。

有沒有人知道如何解決這一問題？

Multiple Android Activities with TabActivity

import java.util.ArrayList; 
import android.app.Activity; 
import android.app.ActivityGroup; 
import android.app.LocalActivityManager; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.KeyEvent; 
import android.view.Window; 

/** 
* The purpose of this Activity is to manage the activities in a tab. 
* Note: Child Activities can handle Key Presses before they are seen here. 
* @author Eric Harlow 
*/ 
public class TabGroupActivity extends ActivityGroup { 
private ArrayList<String> mIdList; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
if (mIdList == null) mIdList = new ArrayList<String>(); 
} 

/** 
* This is called when a child activity of this one calls its finish method. 
* This implementation calls {@link LocalActivityManager#destroyActivity} on the child   activity 
* and starts the previous activity. 
* If the last child activity just called finish(),this activity (the parent), 
* calls finish to finish the entire group. 
*/ 
@Override 
public void finishFromChild(Activity child) { 
LocalActivityManager manager = getLocalActivityManager(); 
int index = mIdList.size()-1; 

if (index < 1) { 
finish(); 
return; 
} 

manager.destroyActivity(mIdList.get(index), true); 
mIdList.remove(index); 
index--; 
String lastId = mIdList.get(index); 
Intent lastIntent = manager.getActivity(lastId).getIntent(); 
Window newWindow = manager.startActivity(lastId, lastIntent); 
setContentView(newWindow.getDecorView()); 
} 

/** 
* Starts an Activity as a child Activity to this. 
* @param Id Unique identifier of the activity to be started. 
* @param intent The Intent describing the activity to be started. 
* @throws android.content.ActivityNotFoundException. 
*/ 
public void startChildActivity(String Id, Intent intent) { 
Window window = getLocalActivityManager().startActivity(Id,intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)); 
if (window != null) { 
mIdList.add(Id); 
setContentView(window.getDecorView()); 
} 
} 

/** 
* The primary purpose is to prevent systems before  android.os.Build.VERSION_CODES.ECLAIR 
* from calling their default KeyEvent.KEYCODE_BACK during onKeyDown. 
*/ 
@Override 
public boolean onKeyDown(int keyCode, KeyEvent event) { 
if (keyCode == KeyEvent.KEYCODE_BACK) { 
//preventing default implementation previous to android.os.Build.VERSION_CODES.ECLAIR 
return true; 
} 
return super.onKeyDown(keyCode, event); 
} 

/** 
* Overrides the default implementation for KeyEvent.KEYCODE_BACK 
* so that all systems call onBackPressed(). 
*/ 
@Override 
public boolean onKeyUp(int keyCode, KeyEvent event) { 
if (keyCode == KeyEvent.KEYCODE_BACK) { 
onBackPressed(); 
return true; 
} 
return super.onKeyUp(keyCode, event); 
} 

/** 
* If a Child Activity handles KeyEvent.KEYCODE_BACK. 
* Simply override and add this method. 
*/ 
@Override 
public void onBackPressed() { 
int length = mIdList.size(); 
if (length > 1) { 
Activity current = getLocalActivityManager().getActivity(mIdList.get(length-1)); 
current.finish(); 
} 
} 
} 

@Override 
public void onBackPressed() { 
TabGroupActivity parentActivity = (TabGroupActivity)getParent(); 
parentActivity.onBackPressed(); 
} 

以下部分解釋我是如何用這個的ActivityGroup。我做的第一件事就是繼承這個的ActivityGroup這樣。

import android.content.Intent; 
import android.os.Bundle; 

public class TabGroup1Activity extends TabGroupActivity { 
@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
startChildActivity("OptionsActivity", new Intent(this,OptionsActivity.class)); 
} 
} 

我將這個TabGroup1Activity添加到了我的TabActivity中。

TabHost tabHost = getTabHost(); 

tabHost.addTab(tabHost.newTabSpec("tab1") 
.setIndicator("MESSAGES") 
.setContent(new Intent(this, TabGroup1Activity.class))); 

然後，任何想要在ActivityGroup中啓動的Activity都可以以類似於此的方式完成。

Intent frequentMessages = new Intent(getParent(), FrequentMessageActivity.class); 
TabGroupActivity parentActivity = (TabGroupActivity)getParent(); 
parentActivity.startChildActivity("FrequentMessageActivity", frequentMessages); 

我做了我所有的活動，在Android清單搜索，我跟着上實現搜索教程。

Creating a Search Interface

此前修改我的代碼與搜索，正在按原計劃，但一些代碼打破了搜索功能TabActivity工作。

我已經發現了我在破譯工作的一個解決方案，但我希望有人更懂得如何將基於在張貼在問題教程示例給出的示例實現它幫助。

這裏是我發現的，但還沒有應用 Nested TabHosts
