在複選框錯誤自定義列表視圖的Android

Question

你好我創建兩個chekboxes和一點改進自定義列表視圖是，當我選中一個複選框，然後向下滾動毗鄰檢查一個也得到遏制，我想知道爲什麼它正在發生其他複選框什麼我應該儘量避免這種錯誤，這是我的代碼

public class ListTestActivity extends ListActivity { 
/** Called when the activity is first created. */ 
String tag = "Events"; 
String[] presidents; 
@Override

    super.onCreate(savedInstanceState); 
// Create an array of Strings, that will be put to our ListActivity 
    presidents =getResources().getStringArray(R.array.pres_array); 

     ArrayAdapter<Model> adapter = new InteractiveArrayAdapter(this, 
       getModel()); 
     Log.d(tag," event"); 
     setListAdapter(adapter); 
     Log.d(tag," 1"); 
    } 

    private List<Model> getModel() { 
     Log.d(tag,"bht"); 
     int index = presidents.length; 
     int positio; 
     String Linux; 
     //List<Model> list = new ArrayList<Model>();

希望它可以幫助

Answer 2

mViewHolder.checkBox = (CheckBox)convertView.findViewById(R.id.checkBox1); 
      mViewHolder.checkBox.setOnClickListener(new OnClickListener() { 
       public void onClick(View v) { 
        CheckBox cb = (CheckBox) v.findViewById(R.id.checkBox1); 
        if (cb.isChecked()) { 
         checkBoxArrayList.set(position, true); 
        } else if (!cb.isChecked()) { 
         checkBoxArrayList.set(position, false); 
        } 
       } 
      });
