Android中常见的对话框

        AlertDialog.Builder builder = new AlertDialog.Builder(this);//内部类
        builder.setTitle("友情提示");
        builder.setMessage("您确定要删除吗?");
        //确定按钮
        builder.setPositiveButton("确定", new OnClickListener() {
            
            @Override
            public void onClick(DialogInterface dialog, int which) {
                //确定删除的代码
                Toast.makeText(MainActivity.this, "删除成功", 0).show();
            }
        });
        //点取消按钮
        builder.setNegativeButton("取消", null);
        
        //显示对话框
        //AlertDialog dialog = builder.create();
