和我的代码是....

package com.android; 

import android.app.TabActivity; 
import android.content.Intent; 
import android.content.res.Resources; 
import android.os.Bundle; 
import android.widget.TabHost; 

public class tab_sample extends TabActivity { 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.tab_sample); 
     TabHost tab=(TabHost)findViewById(R.id.tabhost); 
     tab.setup(); 
     Resources res=getResources(); 
     //tab=getTabHost(); 
     Intent int1=new Intent(this,tab1.class); 
     Intent int2=new Intent(this,tab2.class); 
     tab.addTab(tab.newTabSpec("tab1").setIndicator("Songs",res.getDrawable(R.drawable.tab1)).setContent(int1)); 
     tab.addTab(tab.newTabSpec("tab2").setIndicator("Movie",res.getDrawable(R.drawable.tab2)).setContent(int2)); 
     //tab.addTab(tab.newTabSpec("tab3")) 
     tab.setCurrentTab(0); 
    } 

}

请帮我解决这个问题....

一些重要logcat的线路有：

16：29：46.777：错误/ AndroidRuntime（738）：引起：java.lang.RuntimeException：您的内容必须具有一个TabHost，其id属性是'android.R.id.tabhost'04-29 16：29：46.777 ：

它似乎无法找到你的ID，但这很奇怪，因为这应该会给编译错误。你是否在改变/创建ID的动态？

No.i已经在xml文件中创建了id。 – Eshwar 2011-04-29 13:25:59

如果您使用从图书馆借了一些其他的活动，确保布局文件是不同的。例如。避免使用double main.xml文件。
