Multiple_choice ListView帶圖標

Question

我需要關於ListView的幫助，我是android新手，我必須創建一個ListView multiple_choice（我的意思是右邊的複選框），左邊會有圖標。我列出這個清單，直到選擇一個項目爲止，沒有問題。但是，當我選擇項目複選框是不會被檢查。我使用adapterclass來製作帶有圖標的列表，並使用imageView和CheckedTextView。這裏是我的代碼

public class EfficientAdapter extends BaseAdapter { 
private LayoutInflater mInflater; 
private Bitmap online; 
private Bitmap offline; 
private ArrayList<String> mCurrencyNames; 
public ViewHolder holder; 

public EfficientAdapter(Context context,ArrayList<String> mCurrencyNames) { // Cache the LayoutInflate to avoid asking for a new one each time. 

    mInflater = LayoutInflater.from(context); 
    this.mCurrencyNames = mCurrencyNames; 
    // Icon bound to the row. 
    online = BitmapFactory.decodeResource(context.getResources(), R.drawable.markeronline); 
    offline = BitmapFactory.decodeResource(context.getResources(), R.drawable.markeroffline); 
} 

    /** * The number of items in the list is determined by the number of speeches * in our array. * * @see android.widget.ListAdapter#getCount() */ 
public int getCount() { 
    // return DATA.length; 
    return mCurrencyNames.size(); 
} 

    /** * Since the data comes from an array, just returning the index is * sufficent to get at the data. If we were using a more complex data * structure, we would return whatever object represents one row in the * list. * * @see android.widget.ListAdapter#getItem(int) */ 
public Object getItem(int position) { 
    return position; 
} 


    /** * Use the array index as a unique id. * * @see android.widget.ListAdapter#getItemId(int) */ 
public long getItemId(int position) { 
    return position; 
} 

    /** * Make a view to hold each row. * * @see android.widget.ListAdapter#getView(int, android.view.View, * android.view.ViewGroup) */ 
public View getView(int position, View convertView, ViewGroup parent) { 
    // A ViewHolder keeps references to children views to avoid unneccessary calls 
    // to findViewById() on each row. 

    //When convertView is not null, we can reuse it directly, there is no need 
    // to reinflate it. We only inflate a new View when the convertView supplied 
    // by ListView is null. 
    if (convertView == null) { 
     convertView = mInflater.inflate (R.layout.menu_row, null); 

     // Creates a ViewHolder and store references to the two children views 
     // we want to bind data to. 
     holder = new ViewHolder(); 
     holder.text = (CheckedTextView) convertView.findViewById (R.id.text); 
     holder.icon = (ImageView) convertView.findViewById (R.id.icon); 

     convertView.setTag(holder); 
    } 
    else { 
     // Get the ViewHolder back to get fast access to the TextView 
     // and the ImageView. 
     holder = (ViewHolder) convertView.getTag(); 
    } 

    // Bind the data efficiently with the holder. 
    holder.text.setText(mCurrencyNames.get(position)); 

    String status = Friends.nodelist.get(position).getNamedItem("status").getNodeValue(); 
    if(status.equals("1")){ 
     holder.icon.setImageBitmap(online); 
    } 
    else 
     holder.icon.setImageBitmap(offline); 

    return convertView; 
} 

public void refresh(ArrayList<String> list){ 
    mCurrencyNames = list; 
} 

static class ViewHolder { 
    public CheckedTextView text; 
    public ImageView icon; 
} 

} 

這是我的適配器的代碼，我使用該代碼的解決方案

list.setOnItemClickListener(new OnItemClickListener() { 
      public void onItemClick(AdapterView<?> parent, View view,int position, long id) { 
       RelativeLayout itemLayout = (RelativeLayout)list.getChildAt(position); 
       CheckedTextView ctv = (CheckedTextView)itemLayout.findViewById(R.id.text); 
       ctv.toggle(); 

     } 
    }); 

但這些代碼後，當我選擇它使第一個項目檢查4項。謝謝你的幫助。

Answer 1

將onClickListener設置爲CheckedTextView。它會工作。

OR

設置CheckedTextView的可點擊屬性設置爲false。
