android grid分割线,RecyclerView设置分割线---GridLayoutManager DividerItemDecoration

给GridLayoutManager 设置简单的分割线

mBinding.rvWorkbench.addItemDecoration(

DividerItemDecoration(

activity,

RecyclerView.VERTICAL

)

)

这样设置只能是出现在垂直方向上，缺少了水平方向的

其实我们可以再次设置一次

mBinding.rvWorkbench.addItemDecoration(

DividerItemDecoration(

activity,

RecyclerView.HORIZONTAL

)

)

这样 水平 垂直方向上都有了

当然 你也可以自定义shape

val dividerVertical = DividerItemDecoration(activity, RecyclerView.VERTICAL)

dividerVertical.setDrawable(resources.getDrawable(R.drawable.shape_item_decoration))

mBinding.rvWorkbench.addItemDecoration(dividerVertical)

val dividerHorizontal = DividerItemDecoration(activity, RecyclerView.HORIZONTAL)

dividerHorizontal.setDrawable(resources.getDrawable(R.drawable.shape_item_decoration))

mBinding.rvWorkbench.addItemDecoration(dividerHorizontal)

shape_item_decoration.xml

android:width="1dp"

android:height="1dp" />
