Question

我想在我的应用中使用自定义ListView .. 我创建了一个扩展BaseAdapter的Myadapter。每个项目都有一个文本视图和切换按钮.. 问题是程序，当用户点击项目1的切换按钮时，切换按钮项目4和项目6.自动切换... 我不知道有什么问题请帮帮我... 抱歉。我的英语不好

java代码是：

 public class PayamActivity extends Activity  {



Myadapter adapter;
ListView list;
String [] payam;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_listview);



    payam=getResources().getStringArray(R.array.payam);

     list=(ListView) findViewById(R.id.listView1);
        }
public class Myadapter extends BaseAdapter
{
    LayoutInflater myInflater;
    public Myadapter(Context context) {
        myInflater=LayoutInflater.from(context);

        // TODO Auto-generated constructor stub
    }


    @Override
    public int getCount() {
        // TODO Auto-generated method stub

        return payam.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        ViewHolder Holder;
        ;

        if(convertView==null)
        {
            Holder=new ViewHolder();
            convertView=myInflater.inflate(R.layout.item_custom_layout,null );

            Holder.message=(TextView)convertView.findViewById(R.id.text_massege);

        Holder.heart=(ToggleButton)convertView.findViewById(R.id.toggleButton_heart);
            convertView.setTag(Holder);




        }
        else
            Holder=(ViewHolder) convertView.getTag();



            Holder.message.setText(payam[position]);




        return convertView;
    }

}

public class ViewHolder extends Activity{
    TextView message;
    ToggleButton heart;

}

}

每当您点击toogle按钮时，请将该行位置保留在适合您的arraylist或数组中...

并在getview()

添加这样的代码，

if(array contains the id)
     Holder.heart.setchecked(true);
else
    Holder.heart.setchecked(false);
