Ayuda con Launcher App

[wolfcat90]

Hola! soy nuevo en este foro y necesito vuestra ayuda. He estado desarrollando una aplicacion tipo Launcher, y he empezado por crear un GridView y mostrar ahi todas las apps. Mi problema es que en vez de un GridView aparece un ListView. Alguien puede ayudarme? este es mi codigo:

MainActivity.java

public class MainActivity extends Activity {
private GridView mGrid;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// set layout for the main screen
setContentView(R.layout.layout_main);
// load list application
mGrid = (GridView)findViewById(R.id.lvApps);
// create new adapter
AppInfoAdapter adapter = new AppInfoAdapter(this, Utilities.getInstalledApplication(this), getPackageManager());
// set adapter to list view
mGrid.setAdapter(adapter);
// implement event when an item on list view is selected
mGrid.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
// get the list adapter
AppInfoAdapter appInfoAdapter = (AppInfoAdapter)parent.getAdapter();
// get selected item on the list
ApplicationInfo appInfo = (ApplicationInfo)appInfoAdapter.getItem(pos);
// launch the selected application
Utilities.launchApp(parent.getContext(), getPackageManager(), appInfo.packageName);
}
});
}
}

AppInfo.java


public class AppInfoAdapter extends BaseAdapter {

private Context mContext;

private List<ApplicationInfo> mListAppInfo;

private PackageManager mPackManager;



public AppInfoAdapter(Context c, List<ApplicationInfo> list, PackageManager pm) {

mContext = c;

mListAppInfo = list;

mPackManager = pm;

}



@Override

public int getCount() {

return mListAppInfo.size();

}



@Override

public Object getItem(int position) {

return mListAppInfo.get(position);

}



@Override

public long getItemId(int position) {

return position;

}



@Override

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

// get the selected entry

ApplicationInfo entry = mListAppInfo.get(position);



// reference to convertView

View v = convertView;



// inflate new layout if null

if(v == null) {

LayoutInflater inflater = LayoutInflater.from(mContext);

v = inflater.inflate(R.layout.layout_appinfo, null);

}



// load controls from layout resources

ImageView ivAppIcon = (ImageView)v.findViewById(R.id.ivIcon);

TextView tvAppName = (TextView)v.findViewById(R.id.tvName);

TextView tvPkgName = (TextView)v.findViewById(R.id.tvPack);



// set data to display

ivAppIcon.setImageDrawable(entry.loadIcon(mPackMan ager));

tvAppName.setText(entry.loadLabel(mPackManager));

tvPkgName.setText(entry.packageName);



// return view

return v;

}



}


Utilities.java


public class Utilities {



/*

* Get all installed application on mobile and return a list

* @paramcContext of application

* @returnlist of installed applications

*/

public static List<ApplicationInfo> getInstalledApplication(Context c) {

return c.getPackageManager().getInstalledApplications(Pac kageManager.GET_META_DATA);

}



/*

* Launch an application

* @paramcContext of application

* @parampmthe related package manager of the context

* @parampkgNameName of the package to run

*/

public static boolean launchApp(Context c, PackageManager pm, String pkgName) {

// query the intent for lauching

Intent intent = pm.getLaunchIntentForPackage(pkgName);

// if intent is available

if(intent != null) {

try {

// launch application

c.startActivity(intent);

// if succeed

return true;



// if fail

} catch(ActivityNotFoundException ex) {

// quick message notification

Toast toast = Toast.makeText(c, "Application Not Found", Toast.LENGTH_LONG);

// display message

toast.show();

}

}

// by default, fail to launch

return false;

}

}


layout_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:id="@+id/Example Button"
android:text="Caca"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<GridView
android:id="@+id/lvApps"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>

</LinearLayout>

layout_appinfo.xml

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

<ImageView
android:id="@+id/ivIcon"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_marginRight="5dip"
android:scaleType="center"
/>

<LinearLayout
android:orientation="vertical"
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="1"
>

<TextView
android:id="@+id/tvName"
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:gravity="center_vertical"
/>
</LinearLayout>
</LinearLayout>

Para no ocupar mucho mas espacio he eliminado los imports y el package name.
Espero vuestra ayuda! ;)

Prueba poniendo esto en el Layout Main dentro del GridView

android:numColumns="2"

Y si funciona ya lo cambias por el número que quieras.
