使用recyclerView在底页片段中滚动不起作用

标签： android android-recyclerview fragment

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

<?xml version="1.0" encoding="utf-8"?>

    <RelativeLayout

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

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。
