onBackPressed退出操作提示框  (退出程序写在主入口的结尾)

 @Override    public void onBackPressed() {        //super.onBackPressed();        AlertDialog.Builder builder = new AlertDialog.Builder(this);        builder.setIcon(R.drawable.image1);        builder.setTitle("提示");        builder.setMessage("提示框内容");        builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                finish();            }        });        builder.setNegativeButton("取消",null);        builder.show();    }
