ラジオグループエラーのあるリストビュー

Question

皆リストラジオボタンを追加してラジオボタンを追加したカスタムリストビューを作成していますが、

public class InteractiveArrayAdapter extends ArrayAdapter<Model> { 
String tag = "Events"; 
private final List<Model> list; 
private final Activity context; 

public InteractiveArrayAdapter(Activity context, List<Model> list) { 
    super(context, R.layout.rowbuttonlayout, list); 
    this.context = context; 
    this.list = list; 
} 

static class ViewHolder { 
    protected TextView text; 
    protected CheckBox checkbox,checkbox1; 
    protected RadioGroup mgroup; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    Log.d(tag," 3"); 
    View view = null; 
    if (convertView == null) { 
     LayoutInflater inflator = context.getLayoutInflater(); 
     view = inflator.inflate(R.layout.rowbuttonlayout, null); 
     final ViewHolder viewHolder = new ViewHolder(); 
     viewHolder.text = (TextView) view.findViewById(R.id.label); 
     //viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check); 
     //viewHolder.checkbox1 = (CheckBox) view.findViewById(R.id.checkbox1); 
     viewHolder.mgroup = (RadioGroup) view.findViewById(R.id.radioGroup1); 
     final RadioButton[] mbutton=new RadioButton[5]; 
      for(int l=0;l<5;l++){ 
       mbutton[l]=new RadioButton(context); 
       mbutton[l].setText("test"+l); 


       viewHolder.mgroup.addView(mbutton[l]); 

      } 
      viewHolder.mgroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
       public void onCheckedChanged(RadioGroup mRadioGroup, int checkedId) { 
        for(int i=0; i<mRadioGroup.getChildCount(); i++) { 
         RadioButton btn = (RadioButton) mRadioGroup.getChildAt(i); 
         //int t=table.indexOfChild(table_row); 
         //System.out.println(t); 
         int t=mRadioGroup.getId(); 
         System.out.println(t); 

         if(btn.getId() == checkedId) { 
           String text = btn.getText().toString(); 
           // do something with text 
           Log.d(text," event1"); 
           return; 
         } 
        } 
       } 
      }); 


     view.setTag(viewHolder); 
     Log.d(tag,"me"); 

    } else { 
     view = convertView; 
     Log.d(tag,"meeee"); 

    } 
    ViewHolder holder = (ViewHolder) view.getTag(); 
    holder.text.setText(list.get(position).getName()); 

    Log.d(tag," event7"); 

    return view; 

} 

}

を13行が選択つつあると私は第六に、同じボタン2行目のいずれかのボタンを選択すると、8日、12行目は、私がここで間違ってやっているものを選択しつつあり、私のアダプタクラスI私の作業コードを投稿して、他の人に参考になるようにしてください。

public class InteractiveArrayAdapter extends ArrayAdapter<Model> implements OnClickListener { 
String tag = "Events";

    this.context = context; 
    this.list = list; 
} 

static class ViewHolder { 
    protected TextView text; 
    protected CheckBox checkbox,checkbox1; 
    protected RadioGroup mgroup; 
    protected RadioButton mbutton; 
} 



@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    //Log.d(tag," 3"); 

    View view =null; 
    if (convertView == null) {

     LayoutInflater inflator = context.getLayoutInflater(); 
     view = inflator.inflate(R.layout.rowbuttonlayout, null); 
     final ViewHolder viewHolder = new ViewHolder(); 
     viewHolder.text = (TextView) view.findViewById(R.id.label);

         element.setBte(byt.getId()); 
          element.gte((String) viewHolder.text.getText()); 
         System.out.println("givemeresult"); 
        } 

        }); 


       viewHolder.mgroup.addView(mbutton[l]); 

       } 
     view.setTag(viewHolder); 
      viewHolder.mgroup.setTag(list.get(position)); 


    } else { 
     view = convertView; 
     ((ViewHolder) view.getTag()).mgroup.setTag(list.get(position)); 
     } 
    ViewHolder holder = (ViewHolder) view.getTag(); 
    view.getTag()).mgroup.getTag(); 
    holder.text.setText(list.get(position).getName()); 


    if (list.get(position).getName()==list.get(position).done()){ 

     holder.mgroup.check(list.get(position).isSelected()); 
    } 
    else { 

     holder.mgroup.clearCheck(); 
    } 




    return view; 

}

これは、ビューが再利用されるためです。 ImageViewの（剥奪）の

public class InteractiveArrayAdapter extends ArrayAdapter<Model> { 
String tag = "Events"; 
private final List<Model> list; 
private final Activity context; 

public InteractiveArrayAdapter(Activity context, List<Model> list) { 
    super(context, R.layout.rowbuttonlayout, list); 
    this.context = context.getApplicationContext(); 
    this.list = list; 
} 

static class ViewHolder { 
    protected TextView text; 
    protected CheckBox checkbox,checkbox1; 
    protected RadioGroup mgroup; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    Log.d(tag," 3"); 
    View view = convertView; 
    ViewHolder viewHolder = null; 
    final RadioButton[] mbutton = null; 
    if (view == null) { 
     LayoutInflater inflator = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     view = inflator.inflate(R.layout.rowbuttonlayout, null); 
     viewHolder = new ViewHolder(); 
     viewHolder.text = (TextView) view.findViewById(R.id.label); 
     //viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check); 
     //viewHolder.checkbox1 = (CheckBox) view.findViewById(R.id.checkbox1); 
     viewHolder.mgroup = (RadioGroup) view.findViewById(R.id.radioGroup1); 

     // I'm not sure about this.. 
     // Begin 
     mbutton=new RadioButton[5]; 
     for(int l=0;l<5;l++){ 
      mbutton[l]=new RadioButton(context); 
      mbutton[l].setText("test"+l); 


      viewHolder.mgroup.addView(mbutton[l]); 

     } 

      viewHolder.mgroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
       public void onCheckedChanged(RadioGroup mRadioGroup, int checkedId) { 
        for(int i=0; i<mRadioGroup.getChildCount(); i++) { 
         RadioButton btn = (RadioButton) mRadioGroup.getChildAt(i); 
         //int t=table.indexOfChild(table_row); 
         //System.out.println(t); 
         int t=mRadioGroup.getId(); 
         System.out.println(t); 

         if(btn.getId() == checkedId) { 
           String text = btn.getText().toString(); 
           // do something with text 
           Log.d(text," event1"); 
           return; 
         } 
        } 
       } 
      }); 
     // End 

     view.setTag(viewHolder); 
     Log.d(tag,"me"); 

    } else { 
     viewHolder = (ViewHolder) convertView.getTag(); 

     // Begin 
     mbutton = viewHolder.mgroup; 
     // End 

     Log.d(tag,"meeee"); 

    } 
    ViewHolder holder = (ViewHolder) view.getTag(); 
    holder.text.setText(list.get(position).getName()); 

    Log.d(tag," event7"); 

    return view; 

} 

}

私の実装：あなたはあなたのコード

（convertView == nullの）場合の他にholder.mgroup設定するために私によって変更ビットを持っています：

public class DealAdapter extends ArrayAdapter<DealObject> { 

private Context mContext; 
private Activity mActivity; 
private ArrayList<DealObject> mItems; 
private int mXmlId; 

public DealAdapter(Context context, int textViewResourceId, ArrayList<DealObject> items, Activity activity) { 
    super(context, textViewResourceId, items); 
    this.mContext = context.getApplicationContext(); 
    this.mActivity = activity; 
    this.mItems = items; 
    this.mXmlId = textViewResourceId; 
} 

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    //View v = null; 
    View v = convertView; 
    ViewHolder holder = null; 
    RemoteImageLoader imageLoader = new RemoteImageLoader(mContext, true); 
    RemoteImageView dealImage = null; 

    DealObject mo = mItems.get(position); 
    try { 
     if (v == null) { 
      LayoutInflater vi = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      v = vi.inflate(mXmlId, null); 
      holder = new ViewHolder(); 

      dealImage = (RemoteImageView) v.findViewById(R.id.deal_image); 

      holder.dealImage = dealImage; 
      v.setTag(holder); 
     } else { 
      // Get the ViewHolder back to get fast access to the ImageView. 
      holder = (ViewHolder) convertView.getTag(); 
      holder.dealImage.setBackgroundColor(Color.WHITE); 
      dealImage = holder.dealImage; 
     } 

     if(mo.getImage() != null){ 
      // calling reset is important to prevent old images from displaying in a recycled view. 
      dealImage.reset(); 
      holder.dealImage.setImageUrl(imageUrl); 
      try { 
       holder.dealImage.loadImage(); 
      } 
      catch (Exception ex) { 
      } 
     } 
    } 
    catch (Exception ex) { 
     ex.printStackTrace(); 
    } 
    return v; 
} 

private static final class ViewHolder { 
    private RemoteImageView dealImage; 
} 

}
