基于我在类似情况下的answer here，您可以使用自定义ShapeAppearanceModel 实现此目的，并将自定义CutoutCircleEdgeTreatment（EdgeTreatment 的子类）设置为仅右边缘。

示例用法：

LinearLayout linearLayout = findViewById(R.id.ll_Nav_header_main);
ShapeAppearanceModel shapeAppearanceModel = new ShapeAppearanceModel()
        .toBuilder()
        .setRightEdge(new CutoutCircleEdgeTreatment(getResources(), 80, 20))
        .build();
MaterialShapeDrawable shapeDrawable = new MaterialShapeDrawable(shapeAppearanceModel);
shapeDrawable.setFillColor(ContextCompat.getColorStateList(this, android.R.color.holo_blue_dark));
ViewCompat.setBackground(linearLayout, shapeDrawable);

Xml：

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="wrap_content"
    android:background="@android:color/white">

    <LinearLayout

        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:layout_marginEnd="70dp"
        android:paddingTop="10dp"
        android:paddingBottom="10dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <ImageView
            android:id="@+id/imageView"

            android:layout_marginStart="10dp"
            app:srcCompat="@mipmap/ic_launcher_round" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:layout_marginStart="10dp"
            android:layout_marginEnd="35dp"
            android:text="Header Title Text"
            android:textAppearance="@style/TextAppearance.AppCompat.Body1" />

        <TextView
            android:id="@+id/textView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:layout_marginStart="10dp"
            android:layout_marginEnd="35dp"
            android:text="Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua." />

    </LinearLayout>

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="25dp"
        android:layout_marginEnd="-35dp"
        app:backgroundTint="@android:color/holo_blue_dark"
        app:elevation="3dp"
        app:fabCustomSize="70dp"
        app:layout_constraintTop_toTopOf="@+id/ll_Nav_header_main"
        app:layout_constraintStart_toStartOf="@+id/ll_Nav_header_main"
        app:layout_constraintEnd_toEndOf="@+id/ll_Nav_header_main"
        app:layout_constraintHorizontal_bias="1"
        app:srcCompat="@android:drawable/ic_menu_close_clear_cancel"
        app:tint="@android:color/white" />

</androidx.constraintlayout.widget.ConstraintLayout>   

结果：
