Android Java两个SeekBar的值之和#x27；s使用SetOnSeekbarChangListener或按钮

作为Android中的新手，我尝试使用SetOnSeekbarChangListener或Button简单地添加（求和）两个seekbar的调整值。 下面的项目工作正常，但总数仍然是0。我找不到解决办法。谢谢你的帮助。通常，我使用的是Spring Boot和Vaadin，非常简单：）

您正在主类和侦听器中定义progress1和progress2，因此类变量将保持为0，您必须使用

（您的类名）和same修改主类one而不是上面的侦听器one
最后是工作代码，这可能会帮助其他人。

private int progress1;
private int progress2;
