Android 10 BottomSheetDialogFragment EditText和RecyclerView事件冲突，导致不能正常获取焦点（软件盘弹起后自动关闭，输入内容后失去焦点等问题）

问题一：

键盘不能顶起布局

解决方法：

一般的设置不能解决，需要设置BottomSheetDialogFragment 样式

    <style name="Theme.Design.Light.BottomSheetDialog.WithoutBehavior">
        <item name="bottomSheetStyle">@null</item>
        <item name="android:elevation" ns1:ignore="NewApi">16dp</item>
        <item name="android:windowIsFloating">false</item>
        <item name="android:windowSoftInputMode">stateHidden|adjustResize</item>
    </style>

问题二：

焦点丢失

解决方法：

一：监听焦点丢失时，将其重新设置

   var editValueView: AppCompatEditText? = null
    var isDismission = false  
editValue.apply {                       
                            setOnClickListener{
                                this.openInputMethod()
                            }
                            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
                                onFocusChangeListener = OnFocusChangeListener { v, hasFocus ->
                                    if (!hasFocus) {
                                        if (!isDismission)
                                            this.openInputMethod()
                                    } else {
                                        (v as EditText).setSelection(v.text.length)
                                    }
                                }
                            }
                        }

 override fun onDismiss(dialog: DialogInterface) {
            isDismission = true
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
                editValueView?.closeInputMethodAndClearFocus()
            }
        super.onDismiss(dialog)
    }

openInputMethod:

fun View.openInputMethod(force: Boolean = false) {
    if (force || !isFocused) {
        isFocusable = true
        isFocusableInTouchMode = true
        requestFocus()
        (this as? EditText)?.isCursorVisible = true
        postDelayed({
            (context.getSystemService(INPUT_METHOD_SERVICE) as InputMethodManager).showSoftInput(this@openInputMethod, InputMethodManager.SHOW_FORCED)
        }, 100)
    }
}

closeInputMethodAndClearFocus:

fun EditText.closeInputMethodAndClearFocus() {
    closeInputMethod().apply {
        isCursorVisible = false
        isFocusable = false
        isFocusableInTouchMode = false
        clearFocus()
    }
}

这个方法的缺点是不完美，没有根本解决

方法二：

RecyclerView布局加入：

        android:descendantFocusability="beforeDescendants"
        android:fastScrollEnabled="false"
        android:focusableInTouchMode="false"

同时设置EditText点击事件

 editValue.apply {
    setOnClickListener{
                                openInputMethod()
                            }
}

fun View.openInputMethod(force: Boolean = false) {
    if (force || !isFocused) {
        isFocusable = true
        isFocusableInTouchMode = true
        requestFocus()
        (this as? EditText)?.isCursorVisible = true
        postDelayed({
            (context.getSystemService(INPUT_METHOD_SERVICE) as InputMethodManager).showSoftInput(this@openInputMethod, InputMethodManager.SHOW_FORCED)
        }, 100)
    }
}
