checkbox.setOnCheckedChangeListener：throw java.lang.reflect.InvocationTargetException

Question

以下是我正在使用的适配器。

当我设置setOnCheckedChangeListener时，它抛出异常。
我试图直接在我的活动中使用setOnCheckedChangeListener（没有单独的适配器），但仍然失败。

public class InteractiveArrayAdapter extends ArrayAdapter<String>{ 

private final List<String> list; 
private final Activity context; 
private final int layOut; 

public InteractiveArrayAdapter(Activity context,int rowLayout, List<String> list) { 
    super(context, rowLayout , list); 
    this.context = context; 
    this.list = list; 
    this.layOut = rowLayout; 
} 

static class ViewHolder { 
    protected TextView text; 
    protected CheckBox checkbox; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    View view = null; 
    if (convertView == null) { 
     LayoutInflater inflator = context.getLayoutInflater(); 
     view = inflator.inflate(layOut, null); 
     final ViewHolder viewHolder = new ViewHolder(); 
     viewHolder.text = (TextView) view.findViewById(R.id.callTitle); 
     viewHolder.checkbox = (CheckBox) view.findViewById(R.id.checkbox); 
     viewHolder.checkbox 
       .setOnCheckedChangeListener(checkListener); 
     view.setTag(viewHolder); 
     viewHolder.checkbox.setTag(list.get(position)); 
    } else { 
     view = convertView; 
     ((ViewHolder) view.getTag()).checkbox.setTag(list.get(position)); 
    } 
    ViewHolder holder = (ViewHolder) view.getTag(); 
    holder.text.setText(list.get(position)); 

    return view; 
} 

private OnCheckedChangeListener checkListener = new OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(CompoundButton checkboxView, boolean isChecked) { 

     } 
    }; 

}

Answer 1

试试这个

holder.checkbox 
        .setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
         public void onCheckedChanged(CompoundButton buttonView, 
           boolean isChecked) { 

         } 
        }); 

这对我的作品。
