onRestoreInstanceState 恢复状态 赋值错误

[NQPE]

@OverRide
protected void onRestoreInstanceState(Parcelable state) {
SavedState savedState = (SavedState) state;
super.onRestoreInstanceState(savedState.getSuperState());
this.displayState = savedState.state;
setDisplayState(this.displayState);
}

其中如果设置了 this.displayState = savedState.state; 再调用 setDisplayState(this.displayState); 等于没有实际作用，不应该提前设置状态值 而是直接调用 setDisplayState(savedState.state;);
