You can create an XML file in the drawable folder. Call it, for example, shape.xml
您可以在 drawable 文件夹中创建一个 XML 文件。调用它，例如，shape.xml
In shape.xml:
在shape.xml：
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid
android:color="#888888" >
</solid>
<stroke
android:width="2dp"
android:color="#C4CDE0" >
</stroke>
<padding
android:left="5dp"
android:top="5dp"
android:right="5dp"
android:bottom="5dp" >
</padding>
<corners
android:radius="11dp" >
</corners>
</shape>
The <corner>tag is for your specific question.
该<corner>标签用于您的特定问题。
Make changes as required.
根据需要进行更改。
And in your whatever_layout_name.xml:
而在你的whatever_layout_name.xml：
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_margin="5dp"
android:background="@drawable/shape" >
</LinearLayout>
This is what I usually do in my apps. Hope this helps....
这就是我通常在我的应用程序中所做的。希望这可以帮助....

您将使用Shape Drawable作为布局的背景并设置其cornerRadius。 查看此博客以获取详细教程

Layout
布局
<LinearLayout
android:id="@+id/linearLayout"
android:layout_width="300dp"
android:gravity="center"
android:layout_height="300dp"
android:layout_centerInParent="true"
android:background="@drawable/rounded_edge">
</LinearLayout>
Drawable folder rounded_edge.xml
可绘制文件夹rounded_edge.xml
<shape
xmlns:android="http://schemas.android.com/apk/res/android">
<solid
android:color="@android:color/darker_gray">
</solid>
<stroke
android:width="0dp"
android:color="#424242">
</stroke>
<corners
android:topLeftRadius="100dip"
android:topRightRadius="100dip"
android:bottomLeftRadius="100dip"
android:bottomRightRadius="100dip">
</corners>
</shape>

try this, for Programmatically to set a background with radius to LinearLayout or any View.
试试这个，以便以编程方式将半径设置为 LinearLayout 或任何视图的背景。
private Drawable getDrawableWithRadius() {
GradientDrawable gradientDrawable = new GradientDrawable();
gradientDrawable.setCornerRadii(new float[]{20, 20, 20, 20, 20, 20, 20, 20});
gradientDrawable.setColor(Color.RED);
return gradientDrawable;
}
LinearLayout layout = new LinearLayout(this);
layout.setBackground(getDrawableWithRadius());
