Set drawable for DividerItemDecoration

Question

I'm trying to set my custom drawable (line) for DividerItemDecoration, but with no success. Where is the mistake?

DividerItemDecoration dividerItemDecoration = new DividerItemDecoration(getContext(),                 LinearLayoutManager.VERTICAL); dividerItemDecoration.setDrawable(getContext().getResources().getDrawable(R.drawable.sk_line_divider)); 

XML shape:

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="line">     <stroke         android:width="1dp"         android:color="#000000">     </stroke> </shape> 

Answer 1

Change the shape to rectangle.

Ex:

<shape xmlns:android="http://schemas.android.com/apk/res/android"        android:shape="rectangle">     <size         android:width="1dp"         android:height="1dp" />     <solid android:color="@color/primary" /> </shape> 

Answer 2

Solution (Programmatically):

If you just want to change the color for the dividers instead of creating a custom drawable you can use a ColorDrawable:

DividerItemDecoration itemDecoration = new DividerItemDecoration(recyclerView.getContext(), DividerItemDecoration.VERTICAL); itemDecoration.setDrawable(new ColorDrawable(R.color.greycc)); recyclerView.addItemDecoration(itemDecoration); 

If the size matters in addition to colors you can use a GradientDrawwable:

DividerItemDecoration itemDecoration = new DividerItemDecoration(recyclerView.getContext(), DividerItemDecoration.VERTICAL);  GradientDrawable drawable = new GradientDrawable(GradientDrawable.Orientation.BOTTOM_TOP, new int[]{0xfff7f7f7, 0xfff7f7f7}); drawable.setSize(1,1); itemDecoration.setDrawable(drawable);  recyclerView.addItemDecoration(itemDecoration); 

Please note that setting the color values in the array requires a full octet of hex values, otherwise incorrect colors will be shown i.e., 0xFF3E3E3E as opposed to 0X3E3E3E.
