layout - Android - Custom GridView with separated XML -

my goal display chessboard. have activity displays menu , load instance of "chessview" extends gridview. i've created custom gridview because want have class dedicated display. class have own layout.xml etc ...

gameactivity.java :

protected void oncreate(bundle savedinstancestate)  {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_game);           //init game         cchess.getinstance().init();          //creating chessboard         chessview lchessview = (chessview) findviewbyid(r.id.chessview);      } 

activity_game.xml :

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="@color/background"     tools:context=".gameactivity" >      <project.chess.view.chessview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:id="@+id/chessview"       >     </project.chess.view.chessview>  </relativelayout> 

chessview.java :

public class chessview extends gridview {      public chessview(context pcontext, attributeset pattrs) {         super(pcontext, pattrs);          gridview.inflate(pcontext, r.layout.view_chess, null);          this.setadapter(new chessadapter(pcontext));     } } 

view_chess.xml :

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     >      <gridview          android:id="@+id/gridview"         android:layout_height="wrap_content"         android:layout_width="wrap_content"          android:numcolumns="8"          android:gravity="center"           >     </gridview>  </linearlayout> 

chessadapter.java :

public class chessadapter extends baseadapter {     private context mcontext;      public chessadapter (context pcontext)     {         this.mcontext = pcontext;        }      @override     public int getcount()         {             return 64;         }      @override     public view getview(int position, view convertview, viewgroup parent) {          imageview limageview;         if (convertview == null) {               limageview = new imageview(mcontext);             int size = parent.getwidth()/8;             limageview.setlayoutparams(new gridview.layoutparams(size,size));          //background black or white depending of position         int col = position/8 %2;         if (col == 0)         {             if (position%2 == 0)                 limageview.setbackgroundcolor(color.white);             else                 limageview.setbackgroundcolor(color.black);         }         else         {             if (position%2 == 0)                 limageview.setbackgroundcolor(color.black);             else                 limageview.setbackgroundcolor(color.white);         }          //load images         cpiece p = cchess.getinstance().getpiece(position/8, position%8);           if( p != null)             limageview.setimageresource(mcontext.getresources().getidentifier(p.tostring(), "drawable", mcontext.getpackagename()));     } else {         limageview = (imageview) convertview;     }       return limageview;     }    } 

the result : have 1 column of 64 squares image (my init() in cchess ok). clear, want 8x8 grid standards chessboards.

few days ago, had stuff in 1 activity without custom view simple gridview , working correctly. have broken since i've decided separate code in different classes

i'm sure forgot inflater somewhere don't understand how works , does. i've parsed google hours couldn't find answer.

can me please ? lot reading me , sorry english

i think problem layoutinflator in chessview.java

remove line class

no need inflate gridview in class

 gridview.inflate(pcontext, r.layout.view_chess, null); 

and set column count , gravity in chess view in activity_game.xml file.

android:layout_width="wrap_content"  android:numcolumns="8"  

i think works you.
