    public void popupAlertDialog() {

        // 自定义是否退出程序的对话框
        final Dialog alertdialog = new Dialog(mContext, R.style.CustomDialogTheme);
        alertdialog.getWindow();
        alertdialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        alertdialog.setContentView(R.layout.application_dialog_exit_application);
        alertdialog.setCancelable(false);

        alertdialog.show();// 弹出对话框
        Handler mHandler = new Handler();
        mHandler.postDelayed(new Runnable() {
            @Override
            public void run() {
                alertdialog.dismiss();
            }
