安卓：做的時候複選框被選中的東西

-1

我已創建自定義適配器和兩個佈局文件第一個佈局是包含ListView和Button安卓：做的時候複選框被選中的東西

第二佈局包含將在ListView

表示項目片段視圖

所以

我希望在Checkbox被檢查使Button可見

所有這些操作都將在我的自定義適配器類來完成

這是myCustom適配器

更新

public class LampControllerAdapter extends BaseAdapter { 
Context mContext; 
List<LampModel> mLampModels; 
HashMap<Long,LampModel> selection; 
Button sC; 

    public LampControllerAdapter(Context context, ArrayList<LampModel> lampList) { 

    mContext = context; 
    mLampModels = lampList; 
    selection = new HashMap<Long,LampModel>(); 
    LayoutInflater in = (LayoutInflater) LayoutInflater.from(context); 

    View v = in.inflate(R.layout.fragment_home,null); 
    sC = (Button)v.findViewById(R.id.selection_control); 



} 

@Override 
public int getCount() { 
    return mLampModels.size(); 
} 

@Override 
public Object getItem(int i) { 
    return mLampModels.get(i); 
} 

@Override 
public long getItemId(int i) { 
    return 0; 
} 

@Override 
public View getView(final int i, View view, ViewGroup parent) { 

    ViewHolder holder; 
    final LampModel model = (LampModel) getItem(i); 
    if (view == null) { 
     // Inflating The Layout 
     LayoutInflater inflater = ((Activity) mContext).getLayoutInflater(); 
     view = inflater.inflate(R.layout.lamp_controller_item, parent, false); 
     holder = new ViewHolder(); 

     holder.name = (TextView) view.findViewById(R.id.lamp_item_name); 
     holder.description = (TextView) view.findViewById(R.id.lamp_item_description); 
     holder.select = (CheckBox) view.findViewById(R.id.lamp_item_select); 
     view.setTag(holder); 

    } else { 
     holder = (ViewHolder) view.getTag(); 
    } 


    holder.name.setText(model.getName()); 
    holder.description.setText(model.getDescription()); 
    holder.select.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(CompoundButton compoundButton, boolean b) { 

      if(b){ 
       selection.put(model.getId(),model); 
      }else { 
       selection.remove(model.getId()); 
      } 

      if(selection.size() > 0){ 
       Toast.makeText(mContext, "Not Empty", Toast.LENGTH_SHORT).show(); 
       sC.setVisibility(View.GONE); 
      }else { 
       Toast.makeText(mContext, "Empty", Toast.LENGTH_SHORT).show(); 
      } 

     } 
    }); 


    return view; 
} 


class ViewHolder { 
    TextView name, description; 
    CheckBox select; 
    Switch aSwitch; 
}

}

複選框在哪裏？ – Bills

在列表視圖中顯示的佈局 –

在複選框'checkedListener'上使用回調接口，並使動態可見性 –

試試這個

CheckBox chkBox = (CheckBox) findViewById(R.id.chkBox); 
chkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() 
{ 
    @Override 
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) 
    { 
     if (isChecked) 
     { 
      // perform your action here 
     } 

    } 
});
