android BottomSheet在外面单击时如何折叠? [英] android BottomSheet how to collapse when clicked outside?

问题描述

我已经使用NestedScrollView实现了底页行为.并且想知道是否可以在外部触摸时隐藏底视图.

I have implemented bottomsheet behavior with NestedScrollView. And was wondering if it is possible to hide the bottomsheet view when touched outside.

推荐答案

最后，我能够做到这一点，

Finally I was able to do this,

使用了以下代码行:

@Override public boolean dispatchTouchEvent(MotionEvent event){
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        if (mBottomSheetBehavior.getState()==BottomSheetBehavior.STATE_EXPANDED) {

            Rect outRect = new Rect();
            bottomSheet.getGlobalVisibleRect(outRect);

            if(!outRect.contains((int)event.getRawX(), (int)event.getRawY()))
                mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
        }
    }

    return super.dispatchTouchEvent(event);
}
