Android AlertDialog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();}
