Je souhaite créer un tiroir de navigation à l'aide de RecyclerView et utiliser fragment. Le menu du tiroir de navigation utilise RecyclerView et lorsque vous cliquez sur le menu, passez au fragment sélectionné.Le fragment Android ne s'affichait pas en utilisant recyclerview
J'ai un problème quand je clique sur un menu, mais fragment n'a pas changé
ci-dessous est mon MainActivity.java
package com.ayotong.miranda;
import android.content.Intent;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
import android.support.v4.widget.DrawerLayout;

import android.view.View;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity {
//First We Declare Titles And Icons For Our Navigation Drawer List View
//This Icons And Titles Are holded in an Array as you can see
String TITLES[] = {"Home","Events","Mail","Shop"};
int ICONS[] = {R.drawable.ic_home,R.drawable.ic_article,R.drawable.ic_stat,R.drawable.ic_about};
//Similarly we Create a String Resource for the name and email in the header view
//And we also create a int resource for profile picture in the header view
String NAME = "Akash Bangad";
String COND = "Healthy";
int PROFILE = R.drawable.teh;
int lastMenu = -1;
private Toolbar toolbar; // Declaring the Toolbar Object
RecyclerView mRecyclerView; // Declaring RecyclerView
RecyclerView.Adapter mAdapter; // Declaring Adapter For Recycler View

return true;

return false;
}

});
mLayoutManager = new LinearLayoutManager(this); // Creating a layout Manager
mRecyclerView.setLayoutManager(mLayoutManager); // Setting the layout Manager
Drawer = (DrawerLayout) findViewById(R.id.DrawerLayout); // Drawer object Assigned to the view
mDrawerToggle = new ActionBarDrawerToggle(this,Drawer,toolbar,R.string.openDrawer,R.string.closeDrawer){
@Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
// code here will execute once the drawer is opened(As I dont want anything happened whe drawer is
// open I am not going to put anything here)
}
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
// Code here will execute once drawer is closed
}
}; // Drawer Toggle Object Made
Drawer.setDrawerListener(mDrawerToggle); // Drawer Listener set to the Drawer toggle
mDrawerToggle.syncState(); // Finally we set the drawer toggle sync State
}
private void openFragment(final Fragment fragment) {
android.support.v4.app.FragmentManager fm = getSupportFragmentManager();
android.support.v4.app.FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.container,fragment);
ft.commit();
}
public void onTouchDrawer(final int position) {
if (lastMenu == position) return;
switch (lastMenu = position) {
case 1:
openFragment(new Home_fragment());
break;
case 2:
openFragment(new Stat_fragment());
break;
default:
return;
}
}
}
ci-dessous est Main_activity.xml

ci-dessous est fragment_home.java
package com.ayotong.miranda;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class Home_fragment extends Fragment {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
//returning our layout file
//change R.layout.yourlayoutfilename for each of your fragments
return inflater.inflate(R.layout.fragment_home, container, false);
}
}
S'il vous plaît me aider à résoudre ce donc je peux changer fragment lorsque le menu de navigation sur le tiroir est cliqué.
ne fonctionne pas ... –
