【问题描述】：
所以我很早就问了一个关于如何通过单击按钮来更改文本视图的问题，效果很好！
所以现在...如果我有 1 个 textview 作为计数器，另一个作为限制，我将如何做到这一点，并且当计数器达到限制时，textview1 将回到 0 并且限制会增加。
我试过了：
If (textViewCounter==textViewLimit);
textViewCounter.setText(0);
textViewLimit.setText(textViewLimit.getText().toString() + 100);
但这不起作用... 我还能怎么做？
编辑我的问题只是一个例子。我打算用它来操纵我的价值观。但这就是一切：问题代码位于 btnBattle onClick 的底部

所选代码是我唯一有问题的地方。我没有收到错误。代码只是在错误的时间添加东西
