Android开发 代替 “(XXXX)findViewById()”

public class NActivity extends Activity{
   protected void onCreate(Bundle savedInstanceState){
      setContentView(R.layout.activity_main);
      Button button=getInstances(R.id.button1);
      Button button2=getInstances(R.id.button2);
      TextView tv1=getInstances(R.id.textview1);
      TextView tv2=getInstances(R.id.textview2);
   }
   protected <T extends View> T getInstances(int id) {
        return (T) findViewById(id);
    }

}
