Android 由于选择器重叠，父布局角不可见

android android-layout

Android 由于选择器重叠，父布局角不可见,android,android-layout,textview,android-tabs,android-selector,Android,Android Layout,Textview,Android Tabs,Android Selector,Im尝试使用具有2个文本视图的圆形线性布局构建选项卡 我想要以下输出 发生的情况如下 应用于textview的选择器将绘制在父布局可绘制的顶部，因此角点不可见。我无法将角点添加到textview选择器，因为它将使每个textview中的所有4个角点变圆 我还考虑过使用特定的角点，即塑造每个文本视图，但tht会增加每个文本视图的可绘制数量，这不是一个灵活的解决方案，将来我可能会选择使用更多的选项卡 请大家推荐一个通用的xml解决方案，这样我就可以在不影响父布局角的情况下更改TextView的背

发生的情况如下

应用于textview的选择器将绘制在父布局可绘制的顶部，因此角点不可见。我无法将角点添加到textview选择器，因为它将使每个textview中的所有4个角点变圆

我还考虑过使用特定的角点，即塑造每个文本视图，但tht会增加每个文本视图的可绘制数量，这不是一个灵活的解决方案，将来我可能会选择使用更多的选项卡

请大家推荐一个通用的xml解决方案，这样我就可以在不影响父布局角的情况下更改TextView的背景了吗

这对我有用。。希望你也能这样。

@Sulabh Gajjar-非常感谢你给出如此详细的答案。我考虑过这个方法，但我想知道是否有更好的方法，所以把它作为我最后的选择。 正如您所建议的，为左侧和右侧选项卡创建了2个选择器，而不是创建新的可绘制图形，我在选择器本身中编写了形状，并创建了2个单独的文件来存储不同的角半径，如所建议的。目前它对我有效，但我会再等几天，万一有人想出一个更通用的方法，如果没有人出现，我会把你的答案标记为接受。再次感谢……：）

使用您的方法，下面是我为使其运行所做的
