[résolu] Lancer une activity selon le choix dans une ListView

Picool · March 3, 2011

Bonjour à tous,

J'ai un petit soucis en ce moment c'est que mon application plante quand je clique sur un objet de ma listview...Le but que je cherche à obtenir c'est qu'en "cliquant" sur un élément de ma listView cela lance une autre activité (qui est une nouvelle listView).

Je pense que l'erreur vient du choix pour appeler l'activity :

      maListViewPerso.setOnItemClickListener(new OnItemClickListener() {
       	   public void onItemClick(AdapterView<?> a, View v, int position, long id) {
       	    CallFunc(position);
       	}

		private void CallFunc(int position) {
			Intent intent = getIntent();
        	switch (position) {
        	  case 0:
        	    intent = new Intent(getBaseContext() , Tricks.class);
        	  break;
        	  case 1 :
        	   intent = new Intent(getBaseContext() , Mods.class);
        	  break;
        	  case 2 :
        		  intent = new Intent (getBaseContext () , Combos.class);
        	break;
        	  case 3 :
        		  intent = new Intent (getBaseContext () , Videos.class);

        	}
        	if(intent != null)
        	    startActivity(intent);
		}

Eclipse ne me signale aucun soucis et compile sans problèmes, et j'arrive à lancer l'appli mais au click ça plante...

Pouvez m'aider svp ?

Merci

T'aurais pas oublier de déclarer l'Activity que tu lances dans le androidManifest.xml ?

T'aurais pas oublier de déclarer l'Activity que tu lances dans le androidManifest.xml ?

Elles sont bien déclarés dedans :

       <activity android:name=".Tricks"
                 android:label="@string/app_name">
           <intent-filter>
               <action android:name="android.intent.action.listetricks" />
               <category android:name="android.intent.category.LAUNCHER" />
               </intent-filter>
               </activity>
                       <activity android:name=".Mods"
                 android:label="@string/app_name"
                 android:theme="@android:style/Theme.NoTitleBar">
           <intent-filter>
               <action android:name="android.intent.action.listemods" />
               <category android:name="android.intent.category.LAUNCHER" />
           </intent-filter>
       </activity>
               <activity android:name=".Combos"
                 android:label="@string/app_name"
                 android:theme="@android:style/Theme.NoTitleBar">
           <intent-filter>
               <action android:name="android.intent.action.listecombos" />
               <category android:name="android.intent.category.LAUNCHER" />
           </intent-filter>
       </activity>
               <activity android:name=".Videos"
                 android:label="@string/app_name"
                 android:theme="@android:style/Theme.NoTitleBar">
           <intent-filter>
               <action android:name="android.intent.action.listevideos" />
               <category android:name="android.intent.category.LAUNCHER" />
           </intent-filter>
       </activity>

Et quelle est plus précisément l'erreur qui se produit ?

Picool · March 3, 2011

Force close tout simplement

Et je crois qu'on ne peut pas voir avec le logcat ce qui s'y passe (ou alors je ne sais pas comment bien voir)

Les logs, on peut les voir dans la vue ... LogCat d'Eclipse

Et, généralement, un Force Close génère son lot de traces...

Le logcat des erreurs s'affiche pas quand je test avec mon tel en debug ^^ (la c'est VM)

EDIT : j'ai finalement trouvé mon erreur ! Merci d'avoir essayé de m'aider ça m'a permis de tout de même arrivé à la fin (le soucis était un setContentView(R.layout.xxxx mal renseigné)

Essaye en faisant ça:


maListViewPerso.setOnItemClickListener(new OnItemClickListener() {
                  public void onItemClick(AdapterView<?> a, View v, int position, long id) {
                   CallFunc(position);
               }

                       private void CallFunc(int position) {

                       switch (position) {
                         case 0:
                           Intent intent = new Intent(LeNomDeActivity.this , Tricks.class);
                           startActivity(intent);
                         break;

                         case 1 :
                          Intent intent = new Intent(LeNomDeActivity.this , Mods.class);
                          startActivity(intent);
                          break;

                         case 2 :
                          Intent intent = new Intent (LeNomDeActivity.this , Combos.class);
                          startActivity(intent);
                          break;

                         case 3 :
                          Intent intent = new Intent (LeNomDeActivity.this , Videos.class);
                          startActivity(intent);
                          break;

                       }
                       }
