ActivityGroup应用-如何把一个Activity加载成一个视图

package com.test.activity.group;

import android.app.ActivityGroup;
import android.app.LocalActivityManager;

import android.view.View;
import android.view.View.OnClickListener;

public class MainActivity extends ActivityGroup implements OnClickListener {

private ImageView mImgBtn1 = null;

private ImageView mImgBtn2 = null;

private ImageView mImgBtn3 = null;

private LocalActivityManager mActivityManager = null;

private LinearLayout contentlayout = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

contentlayout = (LinearLayout) findViewById(R.id.content);

mImgBtn1 = (ImageView) findViewById(R.id.btnModule1);
mImgBtn2 = (ImageView) findViewById(R.id.btnModule2);
mImgBtn3 = (ImageView) findViewById(R.id.btnModule3);

mImgBtn1.setOnClickListener(this);
mImgBtn2.setOnClickListener(this);
mImgBtn3.setOnClickListener(this);

mActivityManager = getLocalActivityManager();
}

@Override
public void onClick(View v) {
contentlayout.removeAllViews();
contentlayout.setVisibility(View.VISIBLE);
if (v.getId() == R.id.btnModule1) {
contentlayout.addView(mActivityManager.startActivity("",
new Intent(this, ActivityTest1.class)).getDecorView(),
LinearLayout.LayoutParams.FILL_PARENT,
LinearLayout.LayoutParams.FILL_PARENT);

}
else if(v.getId()==R.id.btnModule2){

/*

这个地方我也用ActivityGroup，所不同的是我是用的LinearLayout把一个个子Activity的view一起放入，而不是一次只是显示一个view，这样导致用getDecorView()之后那些view会带上边框，不知道可不可消掉这些边框
