Android: Add divider between items in RecyclerView

Question

I am using RecyclerView with rounded corner, to make it rounded corner I used below XML:

view_rounded.xml:-

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#008f8471"/>
    <stroke android:width="2dp" android:color="#ffffff" />
    <corners android:radius="10dp"/>
</shape>

fragment_main.xml:-

<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/view_rounded"/>

adapter_main.xml:-

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <TextView
        android:id="@+id/textTitle"
        style="@style/AppTheme.ListTextView"
        />

</LinearLayout>

style.xml:-

<style name="AppTheme.ListTextView" parent="android:Widget.Material.TextView">
  <item name="android:gravity">left</item>
  <item name="android:layout_width">match_parent</item>
  <item name="android:layout_height">wrap_content</item>
  <item name="android:textAllCaps">false</item>
  <item name="android:padding">10dp</item>
  <item name="android:textAppearance">@android:style/TextAppearance.DeviceDefault.Medium</item>
  <item name="android:textColor">@color/tabsScrollColor</item> 
  <item name="android:textStyle">bold</item> 
</style>

Getting (without item separator):

Required (with item separator):

Answer 1

you should try add Divider

mListview.addItemDecoration(new DividerItemDecoration(this.getActivity(), LinearLayout.VERTICAL));

Answer 2

I have done this way:

onCreateView() of Fragment:

RecyclerView recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerView);
recyclerView.addItemDecoration(new SimpleDividerItemDecoration(getActivity()));

SimpleDividerItemDecoration.java:

public class SimpleDividerItemDecoration extends RecyclerView.ItemDecoration {
    private Drawable mDivider;

    public SimpleDividerItemDecoration(Context context) {
        mDivider = context.getResources().getDrawable(R.drawable.recycler_horizontal_divider);
    }

    @Override
    public 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);
        }
    }
}

recycler_horizontal_divider.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <size
        android:width="1dp"
        android:height="1dp" />

    <solid android:color="#2EC590" />

</shape>

Hope this will help you.
