我有多个按钮，每个按钮在单击时加载相同的类。在这个类中，我有一个AsyncTask，我也有两个按钮。一个是安装主题。基本上，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，请下载此文件，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。以下是我的课程。我基本上需要帮助下载与按下的按钮对应的文件...

答案 0 :(得分：0)
您需要在这些陈述中使用getIntExtra()代替getInt()：
int dball = getIntent().getExtras().getInt("Dragon", -1);
int xbox = getIntent().getExtras().getInt("Xbox", -1);
int GameB = getIntent().getExtras().getInt("GameB", 1);
