Code example:

The following is a simple PHP for Android code example that demonstrates how to create a simple interface on an Android device and implement button clicks Event:

<?php
// 创建一个简单的Android界面
echo '<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <Button
        android:id="@+id/my_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="点击我"
        android:onClick="buttonClick" />
</LinearLayout>';

// 定义按钮点击事件处理函数
function buttonClick(){
    echo '<script type="text/javascript">
    alert("按钮被点击了!");
    </script>';
}
?>

In this example, we first created a simple Android interface, containing a button. When the button is clicked, a prompt box will pop up. This code demonstrates how to use PHP for Android to create an Android interface and implement interactive functions.

Through the above examples and introduction of functional features, it can be seen that PHP for Android is a powerful and flexible tool that can provide developers with a convenient development environment and help them quickly develop PHP applications on the Android platform. program.
