Question

我构建了项目，没有错误，但是当我尝试在设备上运行它时，会抛出此错误。

C:\Users\FAISAL NAZIR\.gradle\caches\transforms-2\files-2.1\eaf17b24d60dc773c7680b20ac141638\material-1.1.0\res\layout\mtrl_calendar_month_navigation.xml:32: AAPT: error: 'textEnd' is incompatible with attribute iconGravity (attr) flags [start=1, textStart=2] [weak].

这是显示错误的xml文件，最糟糕的是，该文件是自动生成的，因此我无法对其进行编辑或操作。

我尝试过几次重建项目，我重新启动了android studio，并且还使缓存无效并重新启动，什么都没有发生。

Answer 1

试图升级到1.2.1-rc1，错误仍然存在。在将nuget降级到1.0.0.1后可以使用

Answer 2

错误：“ textEnd”与属性iconGravity不兼容

将com.google.android.material:material:1.1.0用于材料成分

因为它得到了1.1.0-alpha06的支持，所以如果您在1.1.0-alpha06以下使用，它将无法正常工作。参见releases
