activity生命周期的onPause和onStop

搞了这么长时间的android开发，却对一些基础的东西一直模棱两可。。。就比如这个onPause和onStop。如果从一个界面，跳到另一个界面，那么是调用哪个呢？

经过我的实验。搞清楚了。onPause是有活动状态变为非活动状态。onStop()是变为不可见。那么从一个页面跳到另一个页面就是依次调用onPause,onStop.看下程序：

package com.example.fuhe;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
import android.view.View;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
	}
	
	public void click(View view){
		Intent intent = new Intent();
		intent.setClass(this, SS.class);
		startActivity(intent);
	}

	@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;
	}
	
	@Override
	protected void onRestart() {
		super.onRestart();
		Log.e("MainActivity", "onRestart");
	}
	
	@Override
	protected void onResume() {
		super.onResume();
		Log.e("MainActivity", "onResume");
	}
	
	@Override
	protected void onPause() {
		super.onPause();
		Log.e("MainActivity", "onPause");
	}
	
	@Override
	protected void onStop() {
		super.onStop();
		Log.e("MainActivity", "onStop");
	}

}

package com.example.fuhe;

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

public class SS extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.ss);
}

	public void click(View view){
		finish();
	}

}
