其中主要的代码就是：

 //跳转到相应的界面中，获得界面的
Window window  = getLocalActivityManager().startActivity("11",new Intent(ActivityGroupTest1.this,Activity1.class));
scrollView.removeAllViews();
//把activity转化为VIEW，然后放在scrollview中
scrollView.addView( window.getDecorView() );

主界面：

package com.activity.group.test1;import android.app.ActivityGroup;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.View.OnClickListener;
import android.widget.Button;

{Button button1;Button button2;ScrollView scrollView;@Overrideprotected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);//初始化组件System.out.println("ActivityGroupTest1 onCreate");setContentView(R.layout.activity_group);scrollView = (ScrollView)findViewById(R.id.content);button1 = (Button)findViewById(R.id.btu1);//设置监听button1.setOnClickListener( new OnClickListener(){@Overridepublic void onClick(View v){//跳转到相应的界面中，获得界面的Window window  = getLocalActivityManager().startActivity("11",new Intent(ActivityGroupTest1.this,Activity1.class));scrollView.removeAllViews();//把activity转化为VIEW，然后放在scrollview中scrollView.addView( window.getDecorView() );}});button2 = (Button)findViewById(R.id.btu2);button2.setOnClickListener( new OnClickListener(){@Overridepublic void onClick(View v){Window window  = getLocalActivityManager().startActivity("22",new Intent(ActivityGroupTest1.this,Activity2.class));scrollView.removeAllViews();scrollView.addView( window.getDecorView() );}});}@Overrideprotected void onDestroy(){super.onDestroy();System.out.println("ActivityGroupTest1 onDestroy");}@Overrideprotected void onPause(){super.onPause();System.out.println("ActivityGroupTest1 onPause");}@Overrideprotected void onResume(){super.onResume();System.out.println("ActivityGroupTest1 onResume");}@Overrideprotected void onStop(){super.onStop();System.out.println("ActivityGroupTest1 onStop");}}
