        dialog.setMessage("确认报考清华大学？"); //设置内容
        dialog.setPositiveButton("确认", new DialogInterface.OnClickListener() {//确认安妮
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.this, "你真棒", Toast.LENGTH_SHORT).show();
            }
        });
