哇,

Android弹出多选框设计

程序代码功能：点击一个按钮弹出一个多选框

在activity_main.xml布局一个button控件，大小，颜色，位置，背景可自行调节，以被用来在MainActivity.java调用其id来实现点击弹出多选框！在btn1.setOnClickListener(new View.OnClickListener() @Override public void onClick(View view)
大括号内放入点击btn1时间要发生的内容，因为是弹出多选框，所以用来Alter.Builder的知识属性，首先引入AlertDialog.Builder类，然后依次对对话框标题，图片，按钮经行设置，接着不要忘记设置完对话框的属性后，要把它给set实现，代码为

黄色字体为其字符的意思或者功能，代码中不用去写，具体代码在下面的代码段！

dialog//Alter.Builder的参数.setMultiChoiceItems//多选列表(items, null, new DialogInterface.OnMultiChoiceClickListener() 

     @Override
     public void onClick(DialogInterface dialog, int which,//点击的哪一个item boolean isChecked//判断是否选中) 

     
 ).create();

代码编写和注解多有不好，请见谅，若有错误或者不当还望请指出，谢谢！
