安卓——AlertDialog多样按钮

1. 在xml 设计页面添加标签

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.administrator.app_style.MainActivity"
    android:orientation="vertical">

    <Button
    android:id="@+id/b1"
    android:text="click select!"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />
    <Button
        android:id="@+id/b2"
        android:text="click Dx!"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

b1.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        final String[] s={"h5","python","Java","c#","Php","Android"};
        boolean []b={false,false,false,false,false,false};
       new  AlertDialog.Builder(MainActivity.this).setIcon(R.mipmap.ic_launcher)
               .setTitle("问问你，你宣啥？")
               .setPositiveButton("Ok",null)
               .setMultiChoiceItems(s, b, new DialogInterface.OnMultiChoiceClickListener() {
           @Override
           public void onClick(DialogInterface dialog, int which, boolean isChecked) {
               if(isChecked==true)
               {
                   Toast.makeText(MainActivity.this,"你选了："+s[which]+ " 这个语言，看来你很喜欢他啊！",Toast.LENGTH_SHORT).show();
               }
               if(isChecked==false)
               {
