如何在线程android内部显示一个对话框

Question

我正在尝试在我的线程中发生某些事情后显示一个对话框

我在 ui 线程上运行此代码并抛出运行时异常！！

AlertDialog.Builder dlgAlert = new AlertDialog.Builder(context);

    dlgAlert.setMessage(context.getString(R.string.custom_dialog_values_new_high_score));
    dlgAlert.setTitle(context.getString(R.string.custom_dialog_values_new_high_score_title));

    final AlertDialog alertDialog = dlgAlert.create();

    dlgAlert.setPositiveButton(context.getString(R.string.custom_dialog_values_yes_button_text), new DialogInterface.OnClickListener()
    {
        @Override
        public void onClick(DialogInterface arg0, int arg1)
        {
            alertDialog.dismiss();
        }
    });

    dlgAlert.setCancelable(true);

    alertDialog.show();

以下例外是： "执行停止未恢复的活动"

有什么问题？

我该如何解决这个问题？

编辑：

我的主题是：

runOnUiThread(new Runnable()
    {
        public void run()
        {
            try
            {
                                    // it's the function which called dialogbox
                gameIsFinish();
            }
            catch (Exception e)
            {
            }
        }
    });

Logcat 异常：

((Activity)context).runOnUiThread(new Runnable() {

    AlertDialog.Builder dlgAlert = new AlertDialog.Builder(context);

    dlgAlert.setMessage(context.getString(R.string.custom_dialog_values_new_high_score));
    dlgAlert.setTitle(context.getString(R.string.custom_dialog_values_new_high_score_title));

    final AlertDialog alertDialog = dlgAlert.create();

    dlgAlert.setPositiveButton(context.getString(R.string.custom_dialog_values_yes_button_text), new DialogInterface.OnClickListener()
    {
        @Override
        public void onClick(DialogInterface arg0, int arg1)
        {
            alertDialog.dismiss();
        }
    });

    dlgAlert.setCancelable(true);

    alertDialog.show();
});
