Android GridView Example

In res/layout/main.xml layout add GridView as :

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"   
    android:id="@+id/grdview"  
    android:paddingTop="20dp"
    android:layout_width="fill_parent"   
    android:layout_height="fill_parent"  
    android:numColumns="auto_fit"  
    android:verticalSpacing="40dp"  
    android:horizontalSpacing="30dp"  
    android:columnWidth="90dp"  
    android:stretchMode="columnWidth"  
    android:gravity="center"  
/> 

In res/layout/ Create an gridviewitem.xml layout for GridView items as :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:paddingBottom="5dip"
    android:layout_height="fill_parent" >
    
         <ImageView   
               android:layout_height="wrap_content"   
               android:id="@+id/grditemimg"   
               android:layout_width="wrap_content"   
               android:layout_centerHorizontal="true">   
         </ImageView>  
         
         <TextView   
               android:layout_width="wrap_content"   
               android:layout_below="@+id/grditemimg"   
               android:layout_height="wrap_content"   
               android:text="TextView01"   
               android:layout_centerHorizontal="true"   
               android:id="@+id/grditemtxt">  
         </TextView>

</RelativeLayout>

In GridViewActivity :

public class GridViewActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //Remove title bar
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        //Remove notification bar
        this.getWindow().setFlags(WindowManager.LayoutParams.
       FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
        GridView gridview = (GridView) findViewById(R.id.grdview);  
        ArrayList<HashMap<String, Object>> lstImageItem =
             new ArrayList<HashMap<String, Object>>(); 

        HashMap<String,Object> map = new HashMap<String,Object>();
             map.put("itemimg", R.drawable.v01);
             map.put("itemtxt", "Blogger");
             lstImageItem.add(map); 
             map = new HashMap();
             map.put("itemimg", R.drawable.v02);
             map.put("itemtxt", "Facebook");
             lstImageItem.add(map); 
             map = new HashMap();
             map.put("itemimg", R.drawable.v03);
             map.put("itemtxt", "Flickr");
             lstImageItem.add(map); 
             map = new HashMap();
             map.put("itemimg", R.drawable.v04);
             map.put("itemtxt", "Hi5");
             lstImageItem.add(map); 
             map = new HashMap();
             map.put("itemimg", R.drawable.v05);
             map.put("itemtxt", "Linkedin");
             lstImageItem.add(map); 
             map = new HashMap();
             map.put("itemimg", R.drawable.v06);
             map.put("itemtxt", "Netvibes");
             lstImageItem.add(map); 
        SimpleAdapter saImageItems = new SimpleAdapter(this,
                lstImageItem,
                R.layout.gridviewitem,       
                new String[] {"itemimg","itemtxt"},   
                new int[] {R.id.grditemimg,R.id.grditemtxt});  
gridview.setAdapter(saImageItems);  

gridview.setOnItemClickListener(new ItemClickListener());
        
    }
    class  ItemClickListener implements OnItemClickListener  
    {  

 @SuppressWarnings("unchecked")
 @Override
 public void onItemClick(AdapterView arg0, 
           View arg1, int arg2, long arg3) {
 // TODO Auto-generated method stub
 HashMap<String, Object> item=
         (HashMap<String, Object>) arg0.getItemAtPosition(arg2);  
      
 Toast.makeText(GridViewActivity.this, 
        (String)item.get("itemtxt"), Toast.LENGTH_SHORT).show();
 setTitle((String)item.get("itemtxt"));  
        } 
   }
