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>

    2. //多选按钮
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)
{
Toast.makeText(MainActivity.this,"你取消了:"+s[which]+ " 这个语言,看来你移情别恋了啊!",Toast.LENGTH_SHORT).show();
} }
}).show(); }
});
3 单选按钮
        b2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String[] s={"h5","python","Java","c#","Php","Android"}; new AlertDialog.Builder(MainActivity.this).setIcon(R.mipmap.ic_launcher)
