本文针对CannotresolvesymbolKeyEventCompat错误进行了详细的解析，并给出了具体的解决方案。通过替换废弃的KeyEventCompat.hasNoModifiers方法为KeyEvent自带的方法，成功解决了问题。

Cannot resolve symbol KeyEventCompat（android.support.v4.view.KeyEventCompat找不到）
解决方案
KeyEventCompat类（我项目中用它的hasNoModifiers方法）最后查看源码才知道这个hasNoModifiers方法已经被KeyEvent实现了。贴出源码：

public boolean executeKeyEvent(KeyEvent event) {
//报错地方
                    // The focus finder had a bug handling FOCUS_FORWARD and FOCUS_BACKWARD
                    // before Android 3.0. Ignore the tab key on those devices.
//                  if (KeyEventCompat.hasNoModifiers(event)) {
//                      handled = arrowScroll(FOCUS_FORWARD);
//                  } else if (KeyEventCompat.hasModifiers(event, KeyEvent.META_SHIFT_ON)) {
//                      handled = arrowScroll(FOCUS_BACKWARD);
//                  }


//                  http://blog.youkuaiyun.com/lrpshuai/article/details/78392872

//正确代码
                    if (event.hasNoModifiers()) {
                        handled = arrowScroll(FOCUS_FORWARD);
                    } else if (event.hasModifiers(KeyEvent.META_SHIFT_ON)) {
                        handled = arrowScroll(FOCUS_BACKWARD);
                    }
}
