如何更改listview中的分隔符颜色？

    android:id="@+id/list_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:divider="@android:color/darker_gray"
    android:dividerHeight="1dp" />

<View xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="@android:color/darker_gray" />

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view = convertView;
    if (view == null) {
        view = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
    }

    // 设置列表项的数据
    // ...

    // 添加分隔符
    if (position < getCount() - 1) {
        View separator = LayoutInflater.from(context).inflate(R.layout.list_item_separator, parent, false);
        parent.addView(separator);
    }

    return view;
}
