实现的代码，MainActivity.java里：

@Override

public void onCreate(Bundle savedInstanceState){

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

System.out.println("onCreate");

Log.e(TAG, "start onCreate~~~");

}

@Override

public void onStart(){

super.onStart();

System.out.println("onStart");

Log.e(TAG, "start onStart~~~");

}

@Override

public void onResume(){

super.onResume();

System.out.println("onResume");

Log.e(TAG, "start onResume~~~");

}

@Override

public void onPause(){

super.onPause();

System.out.println("onPause");

Log.e(TAG, "start onPause~~~");

}

@Override

public void onStop(){

super.onStop();

System.out.println("onStop");

Log.e(TAG, "start onStop~~~");

}

@Override

public void onDestroy(){

super.onDestroy();

System.out.println("onDestroy");

Log.e(TAG, "start onDestroy~~~");

}

@Override

public void onRestart(){

super.onRestart();

System.out.println("onRestart");

Log.e(TAG, "start onRestart~~~");

}
