集中管理Activity

有时候在设计软件的时候布局复杂的话不利于查看跟更改，这时候我们可以在新建几个Activity，然后用ActivityGroup l来管理这写Activity

package com.android.antking.abv;

import android.app.Activity;
import android.os.Bundle;

public class Activity1 extends Activity{
	 public void onCreate(Bundle savedInstanceState) {
	        super.onCreate(savedInstanceState);
	        setContentView(R.layout.activity1);
	    }
}

 package com.android.antking.abv;

import android.app.ActivityGroup;
import android.content.Intent;
import android.os.Bundle;

import android.view.View;
import android.view.Window;
import android.widget.LinearLayout;



public class MyMain extends ActivityGroup {
    /** Called when the activity is first created. */
   
    Activity1 activity;
    
    LinearLayout layout;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);     
        Intent intent = new Intent(this,Activity1.class);
        layout=(LinearLayout)this.findViewById(R.id.linearLayout1);
        //ActivityGroup管理Activity，Activity转为View
       Window subActivity = this.getLocalActivityManager().startActivity("Activity",intent);
       View view = subActivity.getDecorView();
       layout.addView(view);
       
        
    }
}
