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();
    }
