試試這個..

grid_layout.xml

<?xml version="1.0" encoding="utf-8"?> 
<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/grid_view" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:numColumns="auto_fit" 
    android:columnWidth="90dp" 
    android:horizontalSpacing="10dp" 
    android:verticalSpacing="10dp" 
    android:gravity="center" 
    android:stretchMode="columnWidth" > 

</GridView> 

AndroidGridLayoutActivity.java

import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.AdapterView.OnItemClickListener; 
import android.widget.GridView; 

public class AndroidGridLayoutActivity extends Activity { 

     // Keep all Images in array 
     public Integer[] mThumbIds = { 
       R.drawable.ic_launcher, R.drawable.ic_launcher, 
       R.drawable.ic_launcher, R.drawable.ic_launcher, 
       R.drawable.ic_launcher, R.drawable.ic_launcher, 
       R.drawable.ic_launcher, R.drawable.ic_launcher, 
       R.drawable.ic_launcher, R.drawable.ic_launcher, 
       R.drawable.ic_launcher, R.drawable.ic_launcher, 
       R.drawable.ic_launcher, R.drawable.ic_launcher, 
       R.drawable.ic_launcher 
       }; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.grid_layout); 

     GridView gridView = (GridView) findViewById(R.id.grid_view); 

     // Instance of ImageAdapter Class 
     gridView.setAdapter(new ImageAdapter(this,mThumbIds)); 
    } 
} 

item.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:padding="5dp" > 

    <ImageView 
     android:id="@+id/grid_item_image" 
     android:layout_width="50px" 
     android:layout_height="50px" 
     android:layout_marginRight="10px"> 
    </ImageView> 

</LinearLayout> 

ImageAdapter.java

public class ImageAdapter extends BaseAdapter { 
    private Context context; 
    private final String[] mThumbIds; 

    public ImageAdapter(Context context, String[] mThumbIds) { 
     this.context = context; 
     this.mThumbIds = mThumbIds; 
    } 

    public View getView(int position, View convertView, ViewGroup parent) { 

     LayoutInflater inflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     View gridView; 

     if (convertView == null) { 

      gridView = new View(context); 

      // get layout from mobile.xml 
      gridView = inflater.inflate(R.layout.item, null); 

      // set image based on selected text 
      ImageView imageView = (ImageView) gridView 
        .findViewById(R.id.grid_item_image); 


      imageView.setImageResource(mThumbIds[position]); 


     } else { 
      gridView = (View) convertView; 
     } 

     return gridView; 
    } 

    @Override 
    public int getCount() { 
     return mThumbIds.length; 
    } 

    @Override 
    public Object getItem(int position) { 
     return null; 
    } 

    @Override 
    public long getItemId(int position) { 
     return 0; 
    } 

}
