DataBindingUtil.setContentView（）需要500毫秒

Question

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.d(TAG, "onCreate() called with: savedInstanceState = [" + savedInstanceState + "]");

    mBinding = DataBindingUtil.setContentView(this, R.layout.activity_sensors);
    Log.d(TAG, "onCreate()2 called with: savedInstanceState = [" + savedInstanceState + "]");

    Intent intent = getIntent();
    String address = intent.getStringExtra(ADDRESS_KEY);
    ....
}

04-22 16:51:55.553 7595-7595 / my.app D / SensorsActivity：onCreate（）调用：savedInstanceState = [null] 04-22 16:51:56.053 7595-7595 / my.app D / SensorsActivity：onCreate（）2调用：savedInstanceState = [null]

onCreate（）和onCreate（）2之间的时间是500毫秒，并在应用程序中显示... 任何人都可以暗示为什么会这样？ 非常感谢！
