我在Bottomsheet片段中有一个RecyclerView，该页面的滚动不起作用，我先用约束布局尝试过，后来我移到了相对布局，在这种情况下，它也不起作用。
fragment_layout.xml的主要布局

这是outlet_fragment.xml，当用户开始在EditText中输入位置时显示出口列表

Please help me with this
答案 0 :(得分：0)
我通过使BottomSheet片段不可拖动来解决此问题，以下是此代码：
对于Kotlin-：
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
val bottomsheet = super.onCreateDialog(savedInstanceState)
bottomsheet.setOnShowListener {
//this disables outside touch
// bottomsheet .window.findViewById<View>(R.id.touch_outside)?.setOnClickListener(null)
//this prevents dragging behavior
(bottomsheet.window.findViewById<View>(R.id.design_bottom_sheet)?.layoutParams as CoordinatorLayout.LayoutParams).behavior = null
(bottomsheet.window.findViewById<View>(R.id.design_bottom_sheet)?.layoutParams as CoordinatorLayout.LayoutParams).gravity = Gravity.BOTTOM
}
return bottomsheet
}
这将从下面打开您的片段，要取消片段，您需要在片段外面单击。
