Question

由于我声誉低，我无法发表评论。所以我要扩展这个问题： Disabling User dragging on BottomSheet

Ray W提供的解决方案有效但现在通过在父视图（CoordinatorLayout）上滑动和拖动来扩展。

在该图像中，如果我拖动＆＃34;不需要的拖动区域＆＃34;，则BottomSheet向上滑动。如何在不受欢迎的视图中过滤掉或停止触摸事件？

Answer 1

对于Kotlin，只需在代码中添加以下行，

behaviour.isDraggable = false

Answer 2

将onInterceptTouchEvent函数返回值从Ray W solution更改为：

for ( var index = 0; index < 5; index++ ) {

    var myVar = document.createElement('p');

    myVar.id = 'myVarID' + index;

    myVar.name = 'myVarName' + index;


    //Send request to server

    var data = {};

    var i = 'ind';
    var id = myVar.id;
    var name = myVar.name;

    data[id] = name;
    data[i] = index;

    $.post("script.php", data, function(data){

        console.log("Server response:", data);

    });

}

还有一件事，如果你在BottomSheetLayout中有一个ListView，那么在ListView中滚动项会将bottomSheetBehavior状态改为＆＃34; STATE_DRAGGING＆＃34;来自＆＃34; STATE_EXPANDED＆＃34;。示例代码：

@Override
public boolean onInterceptTouchEvent(CoordinatorLayout parent, V child, MotionEvent event) {
  return super.onInterceptTouchEvent(parent, child, event) && mAllowUserDragging;
}

Answer 3

简单的解决方案，它解决了我遇到的两个问题。

1-它阻止了拖动事件。

2-解决了listView滚动问题

CoordinatorLayout.Behavior<View> behavior;

View profile_config_layout_bottom_sheet = findViewById(R.id.list_view_audience_profile_config_layout);

CoordinatorLayout.LayoutParams layoutParams = (CoordinatorLayout.LayoutParams) profile_config_layout_bottom_sheet.getLayoutParams();
behavior = layoutParams.getBehavior();
assert behavior != null;
((BottomSheetBehavior<View>) behavior).addBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
    @Override
    public void onStateChanged(@NonNull View bottomSheet, int newState) {
        if (newState == BottomSheetBehavior.STATE_DRAGGING) {
            ((BottomSheetBehavior<View>) behavior).setState(BottomSheetBehavior.STATE_EXPANDED);
        } 
    }
    @Override
    public void onSlide(@NonNull View bottomSheet, float slideOffset) {}
});

显示对话框：

（（（BottomSheetBehavior）行为）.setState（BottomSheetBehavior.STATE_EXPANDED）;

Answer 4

看看这个：

SELECT @currank := 0

onBackPress时关闭BottomSheet：

mBottomSheetBehavior1.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
            @Override
            public void onStateChanged(@NonNull View bottomSheet, int newState) {
                if (newState == BottomSheetBehavior.STATE_DRAGGING) {
                    mBottomSheetBehavior1.setState(BottomSheetBehavior.STATE_EXPANDED);
                }
            }

            @Override
            public void onSlide(@NonNull View bottomSheet, float slideOffset) {
                Log.i("BottomSheetCallback", "slideOffset: " + slideOffset);
            }
        });

禁用BottomSheet拖动
