Cómo crear listview onItemclicklistener

Question

Deseo crear listview. Obtuve el valor del JSON. Aquí obtuve el valor de json en listview, pero no puedo obtener el método onItemclickListener. ¿Por qué sucede esto? No lo sé. Por favor, ayúdenme en la codificación como se muestra a continuación.

Logcat no muestra nada.

Gracias.

<ListView 
    android:id="@+id/contests_listView" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_below="@+id/header" 
    android:focusable="true"> 
</ListView> 

Activity.java

public class Activites_Activity extends CheerfoolznativeActivity { 

private ListView contests_listView; 
private ProgressBar pgb; 
ActivitiesBean bean; 
ArrayList<Object> listActivities; 
ListAdapter adapter; 

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.activity_listview); 
    setHeader("Activites"); 


    contests_listView = (ListView) findViewById(R.id.contests_listView); 
    pgb = (ProgressBar) findViewById(R.id.contests_progressBar); 
    listActivities = new ArrayList<Object>(); 

    new FetchActivitesTask().execute(); 

} 

public class FetchActivitesTask extends AsyncTask<Void, Void, Void> { 

    int i =0; 
    @Override 
    protected void onPreExecute() { 
     // TODO Auto-generated method stub 
     super.onPreExecute(); 
     pgb.setVisibility(View.VISIBLE); 
    } 

    @Override 
    protected Void doInBackground(Void... params) { 
     // TODO Auto-generated method stub 

     String url = "my json URL"; 
     String strResponse = util.makeWebCall(url); 

     try { 

      //my json logic here   
     } 
     catch (JSONException e) { 

      e.printStackTrace(); 

     } 

     return null; 
    } 

    @Override 
    public void onPostExecute(Void result) { 
     // TODO Auto-generated method stub 
     super.onPostExecute(result); 

     pgb.setVisibility(View.GONE); 
     displayAdapter(); 
    } 
} 

public void displayAdapter() 
{ 
    adapter = new ListAdapter(this, listActivities); 
    contests_listView.setAdapter(adapter); 
    contests_listView.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, 
       int position, long id) { 

      // Toast.makeText(getApplicationContext(),"Title => "+items.get(position), Toast.LENGTH_SHORT).show(); 

      System.out.println("=========== Click"); 
      bean = (ActivitiesBean) adapter.getItem(position); 

      Intent in1 = new Intent(Activites_Activity.this, Activity_display.class); 
      in1.putExtra("ActivityObject", bean);

Answer 1

Prueba esto:

contests_listView.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener() { 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view,int position, long id) { 
     String item = (String) contests_listView.getItemAtPosition(position); 
     Toast.makeText(this,"You selected : " + item,Toast.LENGTH_SHORT).show();     
    } 
}); 

Answer 2

Prueba este código:

protected void onListItemClick(ListView l, View v, int position, long id) { 

super.onListItemClick(l, v, position, id); 

Toast.makeText(this, "message", Toast.LENGTH_LONG).show(); 
}

Usar este:

contests_listView.setOnItemClickListener(new AdapaterView.OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, 
       int position, long id) { 

      Intent in1 = new Intent(Activites_Activity.this, Activity_display.class); 

      startActivity(in1); 
     } 
    });
