Question

diese Methode erhalten:

public static int showResultTotale(View v) { 

     int totalAmount=0; 

     for (Planet p : plAdapter.getBox()) { 
      if (p.isSelected()){ 
       int quantitaInt= Integer.parseInt(p.getQuantità()); 
       int distanceInt= Integer.parseInt(p.getDistance()); 
       totalAmount+=distanceInt * quantitaInt; 
      } 
     } 
     return totalAmount; 
    } 

Werke ONCLICK einen Knopf, aber ich möchte, dass diese Methode funktioniert, wenn ich auf allen Kontrollkästchen klicken.

Dies ist mein Code:

public class MyListFragment extends Fragment implements 
     CompoundButton.OnCheckedChangeListener{ 

    ListView lv;

Wenn Sie Kontrollkästchen wollen, um Text anzuzeigen, nachdem Sie sie durch onClick() überprüft Methode, um diese dann tun

public class MyListFragment extends Fragment implements View.OnClickListener{ 
.......... 

@Override 
public void onClick(View v) { 

    switch (v.getId()) { 
     case checkBox1.getId: 

      Toast.makeText(
        getActivity(), 
        "blah blah", Toast.LENGTH_SHORT).show(); 
       } 
      ... 
      break; 

     // Add other cases here 

    } 

} 
} 

und laden Sie die CheckBox1 und andere von checkBox1.setOnClickListener(this);

bearbeiten Sorry, ich sehe nicht, Sie verwenden ListView lv so können Sie auch ListView iterieren den Zustand checkbox Für Ihre alten Checkbox findout die kürzlich Ungeprüfter Shop in Sammlung seit ur wie List überzeugen

public class MyListFragment extends Fragment implements View.OnClickListener{ 
List list; 
.......... 

@Override 
public void onClick(View v) { 
    for (int i = 0; i < lv.getChildCount(); i++) { 
    View v = lv.getChildAt(i); 
    if (v instanceof CheckBox) { 
    if (((CheckBox) v).isChecked()) 
     //use toast 
    else 
     list.add("uncheck one"); 
    // use toast for unchecked one 
    } 
}
