添加阴影到圆角TextView？

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FFFFFF" />
    <corners android:radius="10dp" />
</shape>

TextView textView = findViewById(R.id.textView);
textView.setShadowLayer(10, 0, 0, Color.BLACK);

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/rounded_corner"
    android:outlineProvider="com.example.CustomOutlineProvider" />

public class CustomOutlineProvider extends ViewOutlineProvider {
    @Override
    public void getOutline(View view, Outline outline) {
        int cornerRadius = 10;
        outline.setRoundRect(0, 0, view.getWidth(), view.getHeight(), cornerRadius);
    }
}
