我的divIDerItem实现覆盖

 @OverrIDepublic voID onDrawOver(Canvas c, RecyclerVIEw parent, RecyclerVIEw.State state) {    int left = parent.getpaddingleft();    int right = parent.getWIDth() - parent.getpaddingRight();    int childCount = parent.getChildCount();    for (int i = 0; i < childCount; i++) {        VIEw child = parent.getChildAt(i);        RecyclerVIEw.LayoutParams params = (RecyclerVIEw.LayoutParams) child.getLayoutParams();        int top = child.getBottom() + params.bottommargin;        int bottom = top + mdivIDer.getIntrinsicHeight();        mdivIDer.setBounds(left, top, right, bottom);        mdivIDer.draw(c);    }<androID.support.design.Widget.CoordinatorLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"androID:ID="@+ID/main_content"androID:layout_wIDth="match_parent"androID:layout_height="match_parent"><androID.support.v7.Widget.RecyclerVIEw    androID:ID="@+ID/grID"    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent" /><include layout="@layout/new_fab" />

它非常简单.是否有任何建议的步骤来识别和修复这些错误？

谢谢,

解决方法:

这对我有帮助：改变divIDer xml

<?xml version="1.0" enCoding="utf-8"?><shape xmlns:androID="http://schemas.androID.com/apk/res/androID"       androID:shape="line">    <solID androID:color="#00000000"/>    <size androID:height="1dp"/></shape>

至

<?xml version="1.0" enCoding="utf-8"?><shape xmlns:androID="http://schemas.androID.com/apk/res/androID"       androID:shape="line">    <stroke androID:color="#00000000"/>    <size androID:height="1dp"/></shape>

改变固体到中风
