Rufnummer beim Klicken auf Listenansicht Element

Question

Ich habe eine Kontaktlistenaktivität, möchte jedoch einige Funktionen hinzufügen, sodass beim Klicken auf einen Kontakt die Telefonnummer des Anrufers angezeigt wird. Ich habe diesen Code-Schnipsel versucht, aber es passiert nichts, wenn ich auf einen Kontakt tippen:

view.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Intent callIntent = new Intent(Intent.ACTION_CALL); 
       callIntent.setData(Uri.parse("tel:" + currentContact.getPhone())); 
       if (ActivityCompat.checkSelfPermission(context, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) { 
        return; 
       } 
       try{ 
        ((Activity) context).startActivity(callIntent); 
       }catch (Exception e){ 
        e.printStackTrace(); 
       } 

Alle Kontaktaktivitätscode:

public class ContactList extends ActionBarActivity { 

Spinner spinner, spinnerFilter; 
EditText nameTxt, phoneTxt, emailTxt, addressTxt; 
ImageView contactImageimgView, btnSort; 
List<Contact> Contacts = new ArrayList<Contact>(); 
ListView contactListView; 
//Uri imageUri = null; 
AlertDialog alertDialog; 

Bitmap photoTaken; 
String userId; 

boolean isReverseEnabledPriority = false, isReverseEnabledName = false; 
//ArrayList<Contact> contacts; 


@Override

    super.onCreate(savedInstanceState);

    btnSort.setOnClickListener(new View.OnClickListener() { 
     @Override

      String filter = spinnerFilter.getSelectedItem().toString(); 

      if(filter.equals("Priority")){ 

       Collections.sort(Contacts, new Comparator<Contact>() { 
        public int compare(Contact v1, Contact v2) { 
         return v1.getPriorityVal().compareTo(v2.getPriorityVal());

Haben Sie diesen Code versuchen ??

Uri number = Uri.parse("tel:123456789"); 
Intent callIntent = new Intent(Intent.ACTION_DIAL, number); 
startActivity(callIntent);
