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....

3 个答案:

答案 0 :(得分：1)

在xml中，你的tabhost id应为id =“@ android：id / tabhost”检查：Android Tab Host

答案 1 :(得分：0)

一些重要的logcat行是：

16：29：46.777：ERROR / AndroidRuntime（738）：引起：java.lang.RuntimeException：你的内容必须有一个TabHost，其id属性为'android.R.id.tabhost'04-29 16:29 ：46.777：

好像它找不到你的id，但这很奇怪，因为那会产生编译错误。您是否以某种方式动态更改/创建ID？

答案 2 :(得分：0)

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