android - 具有圆角和透明背景的自定义警报对话框

Question

如何设计带有圆角和透明关闭按钮的自定义警报对话框？

Answer 1

像这样创建你的对话框

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                                            context, R.style.CustomAlertDialog);
AlertDialog alertDialog = alertDialogBuilder.create();

在您的 样式.xml

<style name="CustomAlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="android:windowBackground">@drawable/popup_background</item>
</style>

popup_background.xml 写下你想要的任何角落半径

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FFFFFF" />
    <corners android:radius="6dp" />
</shape>

您可以更改拐角半径。祝你好运!
