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);
    }

}

请帮助我解决此问题。…

一些重要的logcat行包括：

16:29:46.777:错误/AndroidRuntime（738）：原因：java.lang.RuntimeException:您的内容必须具有id属性为“android.R.id.TabHost”的TabHost 04-29 16:29:46.777:

---

似乎找不到您的id，但这很奇怪，因为这会导致编译错误。您是否以某种方式动态更改/创建id？

在xml中，您的tabhost id应为id=“@android:id/tabhost”检查此项：

如果您正在使用库中的其他活动，请确保布局文件不同。例如，避免使用双重main.xml文件。

否。我仅在xml文件中创建了id。
