[ CONSULTA ] 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(mPackManager));

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(PackageManager.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.
