以及 Activity 中在这一行出现异常的代码
OnWheelScrollListener scrolledListener = new OnWheelScrollListener() {
public void onScrollingStarted(WheelView wheel) {
wheelScrolled = true;
}
public void onScrollingFinished(WheelView wheel) {
wheelScrolled = false;
}
};
private OnWheelChangedListener days_changedListener = new OnWheelChangedListener() {
public void onChanged(WheelView wheel, int oldValue, int newValue) {
if (!wheelScrolled) {
ChossenTime = duration_optionsList.get(newValue);
}
}
};
任何人都可以帮助我吗，这个应用程序运行完美，一旦遇到这个异常
最佳答案
将你的库文件名更改为“/libs”并检查它。
看起来好像您没有将 jar 正确添加到您的 APK。检查您的项目设置。这是您的设置问题，而不是 API 的错误。
