我有多个按钮，每个按钮在单击时都会加载同一个类。在这个类中，我有一个 AsyncTask，我也有两个按钮。一是安装主题。基本上，当您单击安装时，我需要做的就是下载文件。问题是，我需要下载与我在第一堂课中按下的按钮相对应的文件。基本上，我需要一个 if 语句，并说如果按下按钮 x，则下载此文件，但如果按下按钮 y，则下载此其他文件。我试图自己做，但失败了。下面是我的课。我基本上需要帮助下载与按下的按钮相对应的文件......

您需要在这些语句中使用getIntExtra()而不是：getInt()

        int dball = getIntent().getExtras().getInt("Dragon", -1);
        int xbox = getIntent().getExtras().getInt("Xbox", -1);
        int GameB = getIntent().getExtras().getInt("GameB", 1);
