为什么将设备语言更改为RTL语言时，片段/活动布局看起来不好？

Question

我构建了一个应用程序（用于Android练习），并且为了支持LTR和RTL语言，我使用了[[start和end。我还在清单文件中设置了[[android：supportsRtl =“ true”。当设备设置为LTR语言时，所有文本看起来很好，并且向左对齐很好。 但是，当将设备语言更改为RTL语言时，所有文本似乎都不好，并且没有在右侧对齐（也许某些TextView是对齐的，而有些则不是）。另外，似乎[ view完全是Wrong。我已经附上了两个截屏（两种语言）。我要求您的帮助，因为我不明白自己在做什么。还附带了3个代码片段（一个用于所有布局，第二个用于RecyclerView中的项目，第三个用于Spinner：
