浅谈Android RecyclerView 间距全适配

本文介绍了AndroidRecyclerView间距全适配，分享给大家，具体如下：

LinearLayoutManagerspacing

importandroid.graphics.Rect;
importandroid.support.v7.widget.RecyclerView;
importandroid.view.View;
/**
*Createdbyanonymouson2016/9/90009.
*
*SpacesItemDecoration
*

*mRecyclerView.addItemDecoration(newSpacesItemDecoration(5));
*/
publicclassSpacesItemDecorationextendsRecyclerView.ItemDecoration{
privateintspace;
publicSpacesItemDecoration(intspace){
this.space=space;
}

@Override
publicvoidgetItemOffsets(RectoutRect,Viewview,RecyclerViewparent,RecyclerView.Statestate){
outRect.left=space;
outRect.right=space;
outRect.bottom=space;
//Addtopmarginonlyforthefirstitemtoavoiddoublespacebetweenitems
if(parent.getChildLayoutPosition(view)==0){
outRect.top=space;
}else{
outRect.top=0;
}
}
}

使用方法很简单，上面注释中也已经给出：

mRecyclerView.addItemDecoration(newSpacesItemDecoration(5));

GridLayoutManagerorStaggeredGridLayoutManagerspacing

importandroid.graphics.Rect;
importandroid.support.v7.widget.RecyclerView;
importandroid.view.View;
/**
*Createdbyanonymouson2016/9/90009.
*
*GridSpacingItemDecoration
*

*intspanCount=3;//3columns
*intspacing=50;//50px
*booleanincludeEdge=false;
*recyclerView.addItemDecoration(newGridSpacingItemDecoration(spanCount,spacing,includeEdge));
*/
publicclassGridSpacingItemDecorationextendsRecyclerView.ItemDecoration{
privateintspanCount;
privateintspacing;
privatebooleanincludeEdge;

publicGridSpacingItemDecoration(intspanCount,intspacing,booleanincludeEdge){
this.spanCount=spanCount;
this.spacing=spacing;
this.includeEdge=includeEdge;
}

@Override
publicvoidgetItemOffsets(RectoutRect,Viewview,RecyclerViewparent,RecyclerView.Statestate){
intposition=parent.getChildAdapterPosition(view);//itemposition
intcolumn=position%spanCount;//itemcolumn
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){
outRect.top=spacing;//itemtop
}
}
}
}

此处不仅对间距进行了处理，而且对spanCount也进行了处理，使用方法：

intspanCount=3;//3columns
intspacing=50;//50px
booleanincludeEdge=false;
mRecyclerView.addItemDecoration(newGridSpacingItemDecoration(spanCount,spacing,includeEdge));
