問(wèn)題描述：dialog中editText被軟鍵盤(pán)擋住。
1.在你的dialog的xml文件最外層添加：

<androidx.core.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

</androidx.core.widget.NestedScrollView>

2.你的dialog要繼承Android系統(tǒng)的Dialog

class AppUpdateDialog2(context: Context) :
    Dialog(context, R.style.CustomDialog) {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val layoutParams = window?.attributes
        layoutParams?.apply {
            width = WindowManager.LayoutParams.WRAP_CONTENT
            height = WindowManager.LayoutParams.WRAP_CONTENT
            gravity = Gravity.CENTER
        }
        window?.attributes = layoutParams
        setContentView(R.layout.edit_email_dialog_layout)
        //setCanceledOnTouchOutside(false)//點(diǎn)擊外部不消失
        //setCancelable(false)//點(diǎn)擊返回鍵不消失
        //這行很關(guān)鍵
window?.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN or
                WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN)


    }

}

<style name="CustomDialog" parent="android:style/Theme.Dialog">
        <!--背景顏色及和透明程度-->
        <item name="android:windowBackground">@android:color/transparent</item>
        <!--是否去除標(biāo)題 -->
        <item name="android:windowNoTitle">true</item>
        <!--是否去除邊框-->
        <item name="android:windowFrame">@null</item>
        <!--是否浮現(xiàn)在activity之上-->
        <item name="android:windowIsFloating">true</item>
    </style>

3.使用

val appUpdateDialog =
            activity?.let { AppUpdateDialog2(it) }
        appUpdateDialog?.show()
