Android RecyclerView設定item間距

標籤：

RecyclerView沒有可以直接設定間距的屬性，但可以用ItemDecoration來裝飾一個item，所以繼承重寫ItemDecoration就可以實現間距了

public class SpaceItemDecoration extends RecyclerView.ItemDecoration{            private int space;            public SpaceItemDecoration(int space) {              this.space = space;          }            @Override          public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {                if(parent.getChildPosition(view) != 0)                  outRect.top = space;          }      }

然後在使用RecyclerView的地方：

int spacingInPixels = getResources().getDimensionPixelSize(R.dimen.space); mRecyclerView.addItemDecoration(new SpaceItemDecoration(spacingInPixels));

Adapter填充上，再看看item就有間距了
