分割线


public class MyItemDecoration extends RecyclerView.ItemDecoration {

    private final int spec;

    public MyItemDecoration(Context context, int dpValue) {
        spec = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dpValue, context.getResources().getDisplayMetrics());
    }

    @Override
    public void onDraw(@NonNull Canvas c, @NonNull RecyclerView parent, @NonNull RecyclerView.State state) {
    }


    @Override
    public void onDrawOver(@NonNull Canvas c, @NonNull RecyclerView parent, @NonNull RecyclerView.State state) {
    }


    @Override
    public void getItemOffsets(@NonNull Rect outRect, @NonNull View view, @NonNull RecyclerView parent, @NonNull RecyclerView.State state) {

        outRect.set(spec, spec, 0, 0);
    }
}



 StaggeredGridLayoutManager layoutManager = new StaggeredGridLayoutManager(2, RecyclerView.VERTICAL);
        recyclerView.addItemDecoration(new MyItemDecoration(this,10));
        recyclerView.setLayoutManager(layoutManager);

布局:

 <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginLeft="@dimen/dp_10"
        android:layout_marginRight="@dimen/dp_20"
        android:layout_weight="1"/>
