本文介紹了Android RecyclerView 間距全適配，分享給大家，具體如下：

LinearLayoutManager spacing
import android.graphics.Rect; import android.support.v7.widget.RecyclerView; import android.view.View; /** * Created by anonymous on 2016/9/9 0009. ** SpacesItemDecoration *
* mRecyclerView.addItemDecoration(new SpacesItemDecoration(5)); */ 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.left = space; outRect.right = space; outRect.bottom = space; // Add top margin only for the first item to avoid double space between items if (parent.getChildLayoutPosition(view) == 0) { outRect.top = space; } else { outRect.top = 0; } } }
使用方法很簡單，上面注釋中也已經(jīng)給出：
mRecyclerView.addItemDecoration(new SpacesItemDecoration(5));
GridLayoutManager or StaggeredGridLayoutManager spacing
import android.graphics.Rect; import android.support.v7.widget.RecyclerView; import android.view.View; /** * Created by anonymous on 2016/9/9 0009. ** GridSpacingItemDecoration *
* int spanCount = 3; // 3 columns * int spacing = 50; // 50px * boolean includeEdge = false; * recyclerView.addItemDecoration(new GridSpacingItemDecoration(spanCount, spacing, includeEdge)); */ public class GridSpacingItemDecoration extends RecyclerView.ItemDecoration { private int spanCount; private int spacing; private boolean includeEdge; public GridSpacingItemDecoration(int spanCount, int spacing, boolean includeEdge) { this.spanCount = spanCount; this.spacing = spacing; this.includeEdge = includeEdge; } @Override public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) { int position = parent.getChildAdapterPosition(view); // item position int column = position % spanCount; // item column if (includeEdge) { outRect.left = spacing - column * spacing / spanCount; // spacing - column * ((1f / spanCount) * spacing) outRect.right = (column + 1) * spacing / spanCount; // (column + 1) * ((1f / spanCount) * spacing) if (position < spanCount) { // top edge outRect.top = spacing; } outRect.bottom = spacing; // item bottom } else { outRect.left = column * spacing / spanCount; // column * ((1f / spanCount) * spacing) outRect.right = spacing - (column + 1) * spacing / spanCount; // spacing - (column + 1) * ((1f / spanCount) * spacing) if (position >= spanCount) { outRect.top = spacing; // item top } } } }
此處不僅對間距進行了處理，而且對spanCount也進行了處理，使用方法：

重慶分公司
int spanCount = 3; // 3 columns
int spacing = 50; // 50px
boolean includeEdge = false;
mRecyclerView.addItemDecoration(new GridSpacingItemDecoration(spanCount, spacing, includeEdge));以上就是本文的全部內(nèi)容，希望對大家的學習有所幫助，也希望大家多多支持創(chuàng)新互聯(lián)。
