1、單條橫線及橫線左右間隔
linearlayoutmanager linearlayoutmanager2 = new linearlayoutmanager(getactivity());
linearlayoutmanager2.setorientation(linearlayoutmanager.vertical);
linearlayoutmanager2.setsmoothscrollbarenabled(true);
linearlayoutmanager2.setautomeasureenabled(true);
rvarticle.sethasfixedsize(true);
rvarticle.setlayoutmanager(linearlayoutmanager2);
int spacingleftright = getresources().getdimensionpixelsize(r.dimen.s12);
int spacingbottom = getresources().getdimensionpixelsize(r.dimen.s1);
spacesitemcolordecoration decoration2 = new spacesitemcolordecoration(spacingleftright, spacingbottom, getresources().getcolor(r.color.colordivider));
rvarticle.additemdecoration(decoration2);
rvarticle.setnestedscrollingenabled(false);
marticleadapter = new mainarticlerecycleradapter(getactivity(), articlelist);
rvarticle.setadapter(marticleadapter);
/**
* created by administrator on 2017/10/16.
* int leftright = dip2px(2);
int topbottom = dip2px(2);
rv_content.additemdecoration(new spacesitemdecoration(leftright, topbottom,getresources().getcolor(r.color.colorprimary)));
*/public class spacesitemcolordecoration extends recyclerview.itemdecoration
}@override
public void ondraw(canvas c, recyclerview parent, recyclerview.state state)
int left;
int right;
int top;
int bottom;
final int childcount = parent.getchildcount();
if (layoutmanager.getorientation() == gridlayoutmanager.vertical)
} else }}
@override
public void getitemoffsets(rect outrect, view view, recyclerview parent, recyclerview.state state)
outrect.top = topbottom;
outrect.left = leftright;
outrect.right = leftright;
} else
outrect.top = topbottom;
outrect.left = leftright;
outrect.bottom = topbottom;}}
}
2、多列分割
gridlayoutmanager gridlayoutmanager = new gridlayoutmanager(getactivity(), 2);
recyclerviewtbk.setlayoutmanager(gridlayoutmanager);
// recyclerviewtbk.additemdecoration(new dividergriditemdecoration(getactivity()));
int spancount = 2;//跟布局裡面的spancount屬性是一致的
int spacinginpixels = getresources().getdimensionpixelsize(r.dimen.s10);//每乙個矩形的間距
boolean includeedge = true;//如果設定成false那邊緣地帶就沒有間距s
//設定每個item間距
recyclerviewtbk.additemdecoration(new gridspacingitemdecoration(spancount, spacinginpixels, includeedge));
mtbkadapter = new malltbkadapter(getactivity(), tbklist);
recyclerviewtbk.setadapter(mtbkadapter);
public class gridspacingitemdecoration extends recyclerview.itemdecoration
@override
public void getitemoffsets(rect outrect, view view, recyclerview parent, recyclerview.state state)
outrect.bottom = spacing; // item bottom
} else }}
}
關於recyclerView分隔線取巧
首先吹一波,最近在使用recyclerview做專案.感覺挺好用的,個人推薦大家一起用 關於分隔線問題可以去看這個部落格 這裡我就開始說我取巧的方法了 話不多說 直接上碼 子布局的xml 直接在你recyclerview子布局裡面設定android background color font whi...
線分平面,空間
1 n條直線最多分平面問題 題目大致如 n條直線,最多可以把平面分為多少個區域。析 可能你以前就見過這題目,這充其量是一道初中的思考題。但乙個型別的題目還是從簡單的入手,才容易發現規律。當有n 1條直線時,平面最多被分成了f n 1 個區域。則第n條直線要是切成的區域數最多,就必須與每條直線相交且不...
