Je travaille sur cette application qui a un viewPager et quelques fragments à glisser dans MainActivity. Aujourd'hui, j'ai implémenté le tiroir de navigation mais je ne sais pas comment contrôler quel fragment est affiché dans la classe DrawerItemClickListener du tiroir. Y at-il une solution ou je me déplaçais dans la mauvaise direction et devais changer la façon dont le tiroir de navigation est mis en œuvre? Le tutoriel suggère d'utiliser la méthode getFragmentManager qui ne fonctionne pas pour moi.Contrôler quel fragment est montré à partir de navDrawer
Merci.
est ici classe DrawerItemClickListener:
package com.freestylers.druskischool;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.util.Log;
import android.view.View;
import android.widget.ListView;
import android.widget.AdapterView;
public class DrawerItemClickListener implements ListView.OnItemClickListener
{
public int FragmentNumber;
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long
id) {
selectItem(position);
}
private void selectItem(int position) {
Fragment fragment = null;
switch (position) {
case 0:
fragment = new StartFragment();
FragmentNumber=0;
break;
case 1:
fragment = new MesFragment();
FragmentNumber=1;
break;
case 2:
fragment = new NaujienosFragment();
FragmentNumber=2;
break;
case 3:
fragment = new InstruktoriaiFragment();
FragmentNumber=3;
break;
case 4:
fragment = new MetodikaFragment();
FragmentNumber=4;
break;
case 5:
fragment = new GalerijaFragment();
FragmentNumber=5;
break;
case 6:
fragment = new InstruktoriaiFragment();
FragmentNumber=6;
break;
case 7:
fragment = new AtsiliepimaiFragment();
FragmentNumber=7;
break;
case 8:
fragment = new DrufunparkFragment();
FragmentNumber=8;
break;
case 9:
FragmentNumber=9;
fragment = new KontaktaiFragment();
break;
default:
break;
}
if (fragment != null) {
//tutorial suggests this code:
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
getActionBar().setTitle(mNavigationDrawerItemTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else {
Log.e("MainActivity", "Error in creating fragment");
}
}
}
