AlertDialog之多选和单选对话框

单选对话框，顾名思义就是只能选一项（setSingleChoiceItems(Items,)）

 1 public void click(View v){
 2         //创建对话框类
 3         AlertDialog.Builder builder = new AlertDialog.Builder(this);
 4         //定义item选项
 5         final String items[] = new String[]{"一只","两只","三只"};
 6         builder.setTitle("没有什么事是一只口红解决不了的，如果有那就两只")//设置标题
 7                 .setSingleChoiceItems(items,-1, new DialogInterface.OnClickListener() {//设置单选
 8                     @Override
 9                     public void onClick(DialogInterface dialogInterface, int i) {
10                         Toast.makeText(MainActivity.this,"你选择了用"+items[i]+"口红解决问题",Toast.LENGTH_SHORT).show();
11                 }
12                 }).setPositiveButton("是的", new DialogInterface.OnClickListener() {
13             @Override
14             public void onClick(DialogInterface dialogInterface, int i) {
15                 Toast.makeText(MainActivity.this,"我选择了是",Toast.LENGTH_SHORT).show();
16             }
17         }).setNegativeButton("取消", new DialogInterface.OnClickListener() {
18             @Override
19             public void onClick(DialogInterface dialogInterface, int i) {
20                 Toast.makeText(MainActivity.this,"我选择了取消，因为我相信口红解决不了",Toast.LENGTH_SHORT).show();
21             }
22         }).show();
23     }
