RecyclerView动态设置间隔

首先需要用到自定义一个间距的speace

public class SpacesItemDecoration extends RecyclerView.ItemDecoration{

private int space;

public SpacesItemDecoration(int space){

this.space = space;

    }

@Override

public void getItemOffsets(Rect outRect, View view,

                              RecyclerView parent, RecyclerView.State state){

        outRect.right = space;

// Add top margin only for the first item to avoid double space between items

if(parent.getChildPosition(view) ==0)

            outRect.left = space;

    }

}

然后自定义好之后我们来设置到我们的recyclerView上。

```

int space = UIUtils.dip2Px(15);

recyclerview.addItemDecoration(new SpacesItemDecoration(space));

此处附加UIUtils.dip2Px方法

public static int dip2Px(int dip){

float density = getResource().getDisplayMetrics().density;

int px = (int) ((float) dip * density +0.5F);

return px;

    }

到此我们就实现动态设置间隔了
