BaseActivity如下:

package cn.testmanageactivity;

import android.app.Activity;
import android.os.Bundle;
/**
 * Demo描述:
 * 通过继承BaseActivity,在某个Activity中按下Back
 * 键时关闭所有Activity,从而退出应用
 * 主要方法:
 * 在BaseActivity的onRestart()生命周期方法中
 * 调用finish().
 */
public class BaseActivity extends Activity {
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
	}

	@Override
	protected void onRestart() {
		super.onRestart();
		finish();
	}
}

FirstActivity如下:

package cn.testmanageactivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class FirstActivity extends BaseActivity {
   private Button mButton;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.firstactivity);
		init();
	}
	private void init(){
		mButton=(Button) findViewById(R.id.firstButton);
		mButton.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View view) {
                Intent intent=new Intent(FirstActivity.this,SecondActivity.class);
                startActivityForResult(intent, 9527);
			}
		});
	}
	
	@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		super.onActivityResult(requestCode, resultCode, data);
		System.out.println("FirstActivity 执行方法onActivityResult()," +
		"此时收到来自SecondActivity消亡时传回的数据:test="+data.getStringExtra("test"));
		}
	@Override
	protected void onDestroy() {
		super.onDestroy();
		System.out.println("onDestroy()--->"+this.toString());
	}

}

SecondActivity如下:

package cn.testmanageactivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class SecondActivity extends BaseActivity {
   private Button mButton;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.secondactivity);
		init();
	}
	private void init(){
		mButton=(Button) findViewById(R.id.secondButton);
		mButton.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View view) {
                Intent intent=new Intent(SecondActivity.this,ThirdActivity.class);
                startActivity(intent);
			}
		});
	}
	/**
	 * 注意:
	 * 在此要先完成业务操作
	 * 再调用super.onRestart();
	 * 若先调用super.onRestart();
	 * 那么就直接finish了,业务逻辑
	 * 也就无法执行
	 */
	@Override
	protected void onRestart() {
		Intent intent = new Intent();
		intent.putExtra("test", "hello everyone");
		setResult(111, intent);
		System.out.println("SecondActivity执行覆写后的finish()同时setResult给FirstActivity传值");
		System.out.println("onDestroy()--->"+this.toString());
		super.onRestart();
	}

	@Override
	protected void onDestroy() {
		super.onDestroy();
		System.out.println("onDestroy()--->"+this.toString());
	}

}

ThirdActivity如下:

package cn.testmanageactivity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class ThirdActivity extends BaseActivity {
   private Button mButton;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.thirdactivity);
		init();
	}
	private void init(){
		mButton=(Button) findViewById(R.id.thirdButton);
		mButton.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View view) {
                finish();
			}
		});
	}
	
	@Override
	protected void onDestroy() {
		super.onDestroy();
		System.out.println("onDestroy()--->"+this.toString());
	}

}

firstactivity如下:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
