Activity的七个生命周期函数

只需要修改MainActivity.java即可，要看到效果需要开启LogCat，这个我之前做了笔记http://mengkang.net/102.html，否则不能看到打印出来的内容

package net.mengkang.life;

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

public class MainActivity extends Activity {

	@Override
	protected void onDestroy() {
		// TODO Auto-generated method stub
		super.onDestroy();
		System.out.println("onDestroy");
	}

	@Override
	protected void onPause() {
		// TODO Auto-generated method stub
		System.out.println("onPause");
		super.onPause();
		
	}

	@Override
	protected void onRestart() {
		// TODO Auto-generated method stub
		System.out.println("onRestart");
		super.onRestart();
		
	}

	@Override
	protected void onResume() {
		// TODO Auto-generated method stub
		System.out.println("onResume");
		super.onResume();
		
	}

	@Override
	protected void onStart() {
		// TODO Auto-generated method stub
		System.out.println("onStart");
		super.onStart();
		
	}

	@Override
	protected void onStop() {
		System.out.println("onStop");
		super.onStop();
		
	}

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		System.out.println("onCreate");
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

}

实际测试效果，打开应用，然后关闭应用LogCat的输出情况
