AndroidAlertDialog对话框用法示例

//AlertDialog对话框
public void createAlertDialog(){
  AlertDialog.Builder builder = new AlertDialog.Builder(this);
  builder.setMessage("test AlertDialog");
  builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
  @Override
  public void onClick(DialogInterface dialog, int which) {
      Toast.makeText(getApplicationContext(), "删除成功", Toast.LENGTH_SHORT).show();
    }
  });
  builder.setNegativeButton("no", new DialogInterface.OnClickListener() {
  @Override
  public void onClick(DialogInterface dialog, int which) {
      Toast.makeText(getApplicationContext(), "删除取消", Toast.LENGTH_SHORT).show();
    }
  });
  builder.create().show();
}

//AlertDialog 设置多个选项的条目或者是单选
public void createAtherAlertDialog(){
   //由于AlertDialog的构造方法是protected类型，所以不能直接new这个对象，必须依赖AlertDialog.Builder类
   AlertDialog.Builder builder = new AlertDialog.Builder(this);
   builder = builder.setTitle("与菜单类似的Alert");
   String[] array = {"烤翅","鲍鱼","熊掌","垃圾"};
   boolean[] numbers = {false,false,false,false};
   //被注释的方式是实现单选
//    builder.setItems(array, new DialogInterface.OnClickListener(){
//     @Override
//     public void onClick(DialogInterface dialog, int which) {
//       System.out.println(which);
//     }
//    });
  //下面这种方式是实现多选
   builder.setMultiChoiceItems(array, numbers, new DialogInterface.OnMultiChoiceClickListener(){
    @Override
    public void onClick(DialogInterface dialog, int which,
        boolean isChecked) {
      System.out.println("which : "+which + " isChecked : "+ isChecked);
    }
   });
   builder.create().show();
}
