Activity的生命周期与Fragment的生命周期

 public class MainActivity extends Activity {   
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Fragment f=new ‘所需查看的fragment名称的方法，如：Fragment_Order();‘
        Log.e("HJJ", "Activity &&&& onCreate...");
        // Create the list fragment and add it as our sole content.
        if (getFragmentManager().findFragmentById(android.R.id.content) == null) {
            getFragmentManager().beginTransaction().add(android.R.id.content, f).commit();
        }
    }
 
    @Override
    protected void onStart() {
        // TODO Auto-generated method stub
        super.onStart();
        Log.e("HJJ", "Activity &&&& onStart...");
    }
    
    @Override
    protected void onResume() {
