我正在开发一款能够保持网球比分的应用。一切正常，除了我的下面代码中的几个问题。
1）每次启动应用程序时都必须按RESET按钮，因为计数器会继续增加，并且它可以在条件下工作。 2）无法关闭set1至7-5。 set1继续保持从7-5到8-5,9-5等
任何帮助将不胜感激。

答案 0 :(得分：0)
要将TextView的文字作为String使用textViewCount1.getText().toString()，并比较String使用equals(...)而不是==。
以下是一个例子：
if (CountB == 3 && textViewCount2.getText().toString().equals("40") && textViewCount1.getText().toString().equals("40")) {
textViewCount1.setText("AD");
CountA--;
}
