設置recyclerview條目之間的距離

AppinfoiItemDecoration decor = new AppinfoiItemDecoration(); //設置條目的間距 recycler.addItemDecoration(decor);

 

 

 複寫 getItemOffsets 方法設置left right bottom 和top 的距離 

 

@Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) { //不是第一個的格子都設一個左邊和底部的間距  int pos = parent.getChildAdapterPosition(view);  outRect.left = 10;  if (pos != 0) { if (pos % 2 == 0) { //下面一行  outRect.bottom =30;  outRect.top = 5;  } else { //上面一行  outRect.top = 30;  outRect.bottom = 5;  } } }
