Android开发之TabActivity用法实例详解

设置View的id ：

setContent(int viewId)

用new Intent 来引入其他Activity的内容：setContent(Intent intent)

package com.zhanglong.music;
import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
import android.widget.TabHost;
public class MainActivity extends TabActivity
{
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState)
  {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
     WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.main);
    Resources res = getResources();
    TabHost tabHost = getTabHost();
    TabHost.TabSpec spec;
    Intent intent;
    intent = new Intent().setClass(this, ListActivity.class);
    spec = tabHost.newTabSpec("音乐").setIndicator("音乐",
             res.getDrawable(R.drawable.item))
           .setContent(intent);
    tabHost.addTab(spec);
    intent = new Intent().setClass(this, ArtistsActivity.class);
    spec = tabHost.newTabSpec("艺术家").setIndicator("艺术家",
             res.getDrawable(R.drawable.artist))
           .setContent(intent);
    tabHost.addTab(spec);
    intent = new Intent().setClass(this, AlbumsActivity.class);
    spec = tabHost.newTabSpec("专辑").setIndicator("专辑",
             res.getDrawable(R.drawable.album))
           .setContent(intent);
    tabHost.addTab(spec);
    intent = new Intent().setClass(this, SongsActivity.class);
    spec = tabHost.newTabSpec("最近播放").setIndicator("最近播放",
             res.getDrawable(R.drawable.album))
           .setContent(intent);
    tabHost.addTab(spec);
    tabHost.setCurrentTab(0);
  }
}
