If you get hold of the ListView object in your Activity you can use the method setLayoutParams(), passing in an instance of android.view.ViewGroup.MarginLayoutParams.
如果您在 Activity 中获得 ListView 对象，则可以使用setLayoutParams()方法，传入android.view.ViewGroup.MarginLayoutParams的实例。

More simply, you may be able to modify the existing MarginLayoutParams instance to modify the margin:
更简单地说，您可以修改现有的 MarginLayoutParams 实例来修改边距：
ViewGroup.MarginLayoutParams mlp = (ViewGroup.MarginLayoutParams) mListView
.getLayoutParams();
mlp.setMargins(adjustmentPxs, 0, 0, 0);
break;
