如果您使用的是

android:shape="rectangle">
<solid android:width="3dp"
android:color="@color/colorPrimary"

If you are using the NavigationView
in the Material Components library, you can apply a custom ShapeAppearanceModel
to the corner of the your NavigationView
.
Something like:
float radius = getResources().getDimension(R.dimen.roundcorner);
NavigationView navigationView = findViewById(R.id.nav_view);
MaterialShapeDrawable navViewBackground = (MaterialShapeDrawable) navigationView.getBackground();
navViewBackground.setShapeAppearanceModel(
navViewBackground.getShapeAppearanceModel()
.toBuilder()
.setTopRightCorner(CornerFamily.ROUNDED,radius)
.setBottomRightCorner(CornerFamily.ROUNDED,radius)
.build());
In this way the NavigationView
has rounded corners.
Now you have to pay attention to the header layout to build a rounded corner on the top. You have to use as background for the header view, something like:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:background="@drawable/side_nav_bar"
...>
where the side_nav_bar is
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
....
<corners android:topRightRadius="32dp" />
</shape>
Don't use a rounded corner on the bottom, because it is only the view used on the header of the NavigationView.
The ShapeAppearanceModel
requires the version 1.1.0 of material components (currently 'com.google.android.material:material:1.1.0-alpha10'
)
