Question

在更改活动和应用转换时，我无法使状态栏不闪烁。

的活动：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_basic);
    setupTransitions();
}

private void setupTransitions() {
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
        setupEnterTransition();
        setupReenterTransition();
        setupExitTransition();
        setupReturnTransition();
    }
}

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
private void setupEnterTransition(){
    Slide slide = new Slide(Gravity.END);
    slide.excludeTarget(R.id.activity_header, true);
    setEnterTransition(slide);
}

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
private void setupReenterTransition(){
    Slide slide = new Slide(Gravity.START);
    slide.excludeTarget(R.id.activity_header, true);
    setReenterTransition(slide);
}

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
private void setupExitTransition(){
    Slide slide = new Slide(Gravity.TOP);
    slide.excludeTarget(R.id.activity_header, true);
    setExitTransition(slide);
}

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
private void setupReturnTransition(){
    Slide slide = new Slide(Gravity.BOTTOM);
    slide.excludeTarget(R.id.activity_header, true);
    setReturnTransition(slide);
}

protected void setEnterTransition(Transition transition) {
   if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
       getWindow().setEnterTransition(setUpTransition(transition, true));
   }
   }

setExitTransition，setReenterTransition和setReturnTransition看起来相同，但调用了适当的方法，所以我没有复制它们。

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
private Transition setUpTransition(Transition transition){
    transition.setDuration(250);
    transition.excludeTarget(android.R.id.statusBarBackground, true);
    transition.excludeTarget(android.R.id.navigationBarBackground, true);
    return transition;
}

我按以下步骤开始转换：

public void transitionTo(Intent intent){
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        ActivityOptionsCompat transitionActivityOptions = ActivityOptionsCompat.makeSceneTransitionAnimation(this);
        startActivity(intent, transitionActivityOptions.toBundle());
    }else{
        startActivity(intent);
    }
}

我将窗口的背景设置为drawable，以避免在转换运行时看到屏幕变黑。

getWindow().setBackgroundDrawable(new ColorDrawable(ContextCompat.getColor(this, R.color.backgroundColor)));

所以问题是当我从Activity1传递到Activity2（它们共享相同的代码）时，将应用转换并且状态栏不会闪烁。

但是，通过按工具栏中的backButton或home项目返回上一个Activity1，转换将适用，但状态栏会闪烁。

我已尝试过post中建议的两种方法，但根本没有成功。

应用转场时，状态栏会闪烁
