一个通用的RecyclerView的分割线，支持LinearLayoutManager和GridLayoutManager。只要你能描述清楚每个position上下左右分割线的情况，原则上支持任意LayoutManager
- LinearLayoutManager和GridViewLayoutManager通用
- 以每个item的上、下、左、右每条边为控制单位
- 可以单独控制每边是否显示
- 可以单独控制每边的颜色
- 可以单独控制每边的宽度
- 可以单独控制每边的 startPadding 和 endPadding
将依赖加入你项目的build.gradle中:
compile 'com.yanyusong.y_divideritemdecoration:y_divideritemdecoration:2.0'
新建一个对象实现抽象类 Y_DividerItemDecoration ，在 getDivider(int itemPosition) 中定义在itemPosition时条目的分割线情况，有无、颜色、宽度、startpadding 和 endpadding 。
private class DividerItemDecoration extends Y_DividerItemDecoration {
private DividerItemDecoration(Context context) {
super(context);
}
@Override
public Y_Divider getDivider(int itemPosition) {
Y_Divider divider = null;
switch (itemPosition % 2) {
case 0:
//每一行第一个显示rignt和bottom
divider = new Y_DividerBuilder()
.setRightSideLine(true, 0xff666666, 10, 0, 0)
.setBottomSideLine(true, 0xff666666, 20, 0, 0)
.create();
break;
case 1:
//第二个显示Left和bottom
divider = new Y_DividerBuilder()
.setLeftSideLine(true, 0xff666666, 10, 0, 0)
.setBottomSideLine(true, 0xff666666, 20, 0, 0)
.create();
break;
default:
break;
}
return divider;
}
}
给RecyclerView添加刚才实现的ItemDecoration
recyclerView.addItemDecoration(new DividerItemDecoration(this));
