Plusieurs fichiers html fragmentés en utilisant webView via ListView

Question

J'ai créé une application webview avec listview fragmenté. J'ai suivi ce lien: Opening multiple local html files using webView via ListView Lorsque je clique sur l'élément, il doit me rediriger vers les détails de l'élément de webview. Maintenant j'essaye de l'implémenter dans le fragment Mais un seul article est réussi tandis que les autres articles ne me pointent pas au détail de webview qui devrait être. Je cherchais une solution mais toujours pas de chance. Voici mon code

MainActivity:

package com.listviewfragment.withsublist; 

import android.support.v4.app.FragmentTransaction; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 

public class MainActivity extends AppCompatActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    Main_listFragment main_listFragment = new Main_listFragment(); 
    FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); 
     fragmentTransaction.replace(R.id.content, main_listFragment); 
     fragmentTransaction.commit(); 
    } 
} 

activity_main.xml

Answer 1

Vous utilisez fragment même détail pour toutes les positions 0,1,2. Il suffit de faire comme ceci:

Detail_webview_mainFragment dlm = new Detail_webview_mainFragment(); 
Bundle args = new Bundle(); 
args.putInt("key", pos); 
dlm.setArguments(args); 

et au lieu de

int pos = getActivity().getIntent().getIntExtra("key", 0); 

dans le fragment de détail faire:

int pos=0; 
if (getArguments() != null) {  
pos= getArguments().getInt("key");    
}
