Android事件回调函数，有的手机d w v i不显示，怎么调制，好像是手机开发者选项？谢谢

@Override
protected void onStart() { //开始启动
super.onStart();
Log.e("====SecondActivity=","onStart");
Log.d("====SecondActivity=","onStart");
Log.w("====SecondActivity=","onStart");
Log.v("====SecondActivity=","onStart");
Log.i("====SecondActivity=","onStart");
}

这个问题还真没有试过，你还真喜欢尝试啊，不错不错
