下来是布局文件，很简单就5个button

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="diaog.com.diaogdemo.MainActivity">
    
        <Button android:id="@+id/normal_btn" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="普通对话框" />
    
        <Button android:id="@+id/list_btn" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@+id/normal_btn" android:text="列表对话框" />
    
        <Button android:id="@+id/choice_btn" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@+id/list_btn" android:text="单选列表对话框" />
    
        <Button android:id="@+id/more_choice_btn" android:layout_width="match_parent" android:layout_below="@+id/choice_btn" android:layout_height="wrap_content" android:text="多选列表对话框" />
        <Button android:id="@+id/editext_btn" android:layout_width="match_parent" android:layout_below="@+id/more_choice_btn" android:layout_height="wrap_content" android:text="可编辑输入对话框" />
    </RelativeLayout> 效果展示
