零基础Android学习笔记-02 安卓程序生命周期

一个安卓程序生命周期会经历7中状态，并不一定是每次都全部经历。Create,Start,ReStart,Pause,Resume,Stop,Destory.

重载方法，用helloWorld程序去体验下他们时候时候会执行。

 public class MainActivity extends Activity {
     public final String TAG = "Main";

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         Log.i(TAG, "onCreate被执行了.");
     }

     @Override
     protected void onStart() {
         // TODO Auto-generated method stub
         super.onStart();
         Log.i(TAG, "onStart被执行了.");
     }

     @Override
     protected void onRestart() {
         // TODO Auto-generated method stub
         super.onRestart();
         Log.i(TAG, "onRestart被执行了.");
     }

     @Override
     protected void onPause() {
         // TODO Auto-generated method stub
         super.onPause();
         Log.i(TAG, "onPause被执行了.");
     }

     @Override
     protected void onResume() {
         // TODO Auto-generated method stub
         super.onResume();
         Log.i(TAG, "onResume被执行了.");
     }

     @Override
     protected void onStop() {
         // TODO Auto-generated method stub
         super.onStop();
         Log.i(TAG, "onStop被执行了.");
     }

     @Override
     protected void onDestroy() {
         // TODO Auto-generated method stub
         super.onDestroy();
         Log.i(TAG, "onDestroy被执行了.");
     }

     @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;
     }

 }
