小编raj*_*war的帖子

我实现了一个Android应用程序.我想在评级按钮点击时调用或弹出片段.

例如,这里我附上了截图.当我点击率按钮时,如何调用这样的弹出窗口或片段

请帮我怎么称这些片段？

我在android studio中得到java.lang.NoClassDefFoundError,当我在我的项目中添加一个新类时,其余代码没有检测到类(由于没有按预期工作,它没有给出任何编译时错误).在这种情况下,我添加了一个UtilDateTime类,它给出了java.lang.NoClassDefFoundError.请帮助我这可能似乎不是一个编码问题,但与我正在使用的库相关的东西(虽然我不确定问题的痛苦).
