java无法在文本视图数组中应用字符串值
在if（saveInstanceState！=null）中，我试图保存whowen（）方法在文本视图中对文本所做的更改，以便在用户旋转手机时将其保存并恢复到旋转前的状态，但它显示了一个错误，即TextView中的getText（）无法应用于（java.lang.string），我尝试添加。toString（）但它不起作用

getText()不接受参数mTicTacTextViews[i].getText()返回视图中的文本。你想在视图中设置文本吗？如果是这样，你想要的是setText(CharSequence)，而不是CharSequence getText()
