我试图禁止用户拖动BottomSheet。我要禁用的原因有两点。1.防止ListView向下滚动。2.我不希望用户通过拖动来撤消操作，而是使用上的按钮BottomSheetView。这就是我所做的
bottomSheetBehavior = BottomSheetBehavior.from(bottomAnc);
bottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
if (newState == BottomSheetBehavior.STATE_EXPANDED) {
//Log.e("BottomSheet", "Expanded");
} else if (newState == BottomSheetBehavior.STATE_COLLAPSED) {
//Log.e("BottomSheet", "Collapsed");
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
// React to dragging events
bottomSheet.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int action = MotionEventCompat.getActionMasked(event);
switch (action) {
case MotionEvent.ACTION_DOWN:
return false;
default:
return true;
}
}
});
}
});bottomSheetLayout
