我有一个抽屉布局需要有两个导航视图，因为有几个选项需要在顶部对齐，另一个在底部对齐，分隔符将它们分开。
我已经设法使其工作，但现在我的设置有两个不同的问题。
1）第一个，我无法更改所选项目的文本颜色（背景颜色通过抽屉选择器工作，但由于某种原因，所选项目的文本颜色始终为colorPrimary）
2）第二个是比较棘手的，因为有两个导航视图，可能会发生在第一个和第二个上有一个选定的行，即使它们都在同一个容器中加载片段。有没有办法管理它，当选择第一个导航视图的项目时，第二个导航视图的所选项目被取消选择？
这是抽屉的布局：

任何帮助将不胜感激！ 提前谢谢！
答案 0 :(得分：0)
解决！ 颜色的问题我用选择器解决了它，它之前没有用，因为我有一个语法错误（主选择器标签内的选择器标签）。
这是颜色选择器的代码：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#FFFFFFFF" android:state_checked="true" />
<item android:color="#E6000000" android:state_checked="false"/>
</selector>
第二个问题我通过编程方式取消选择onNavigationItemSelected上的其他导航视图的项目来解决它。
这是我打电话的功能：
public void deselectItems(NavigationView view){
int size = view.getMenu().size();
for (int i = 0; i < size; i++) {
view.getMenu().getItem(i).setChecked(false);
}
}
我知道必须有更好的方法来解决第二个问题，但这个问题有效。
