1. Create a custom layout page file in the layout folder

Right-click layout -> new -> Layout Resource File

 2. Write the mylogin.xml file

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="300sp"
    android:layout_height="160sp"
    android:orientation="vertical"
    android:padding="10sp"
    android:gravity="center">
    <EditText

        android:layout_height="wrap_content"
        android:id="@+id/et_username"
        android:hint="请输入账号"/>
    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/et_pwd"
        android:hint="请输入密码"/>
    <Button

        android:layout_height="wrap_content"
        android:id="@+id/btn_login"
        android:text="登录"/>

</LinearLayout>

3. Write Java code

 // TODO 5、自定义样式弹出框
        btn_5.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
