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...
