如何从其视图模型设置Android视图的左边界和右边界？

我尝试如下定义视图模型：

  public int marginRight;
public int marginLeft;

@BindingAdapter("android:layout_marginLeft")
public static void setLeftMargin(View view,int margin) {
    ViewGroup.MarginlayoutParams marginParams = new ViewGroup.MarginlayoutParams(view.getLayoutParams());
    int ml = (int) TypedValue.applyDimension(
            TypedValue.COMPLEX_UNIT_DIP,margin,view.getcontext().getResources().getDisplayMetrics());
    marginParams.leftMargin = ml;
    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(marginParams);
    view.setLayoutParams(layoutParams);
}

@BindingAdapter("android:layout_marginRight")
public static void setRightMargin(View view,view.getcontext().getResources().getDisplayMetrics());
    marginParams.rightMargin= ml;
    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(marginParams);
    view.setLayoutParams(layoutParams);
}

但是，问题是只有其中之一被设置。在绑定适配器中，所有边距都显示为0。

如何解决此问题？
