Question

Android中使用ListView，点击Item的时候如何改变对应的TextView显示的值？

如下贴出片段代码，我点击Item时可以把变更值存储至List<Map<String, Object>>中，如何同步TextView内容显示呢？
public class UUTAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private List<Map<String, Object>> mData;

public UUTAdapter(Context context, List<Map<String, Object>> listMap) {
// TODO Auto-generated constructor stub
this.mInflater = LayoutInflater.from(context);
this.mData = listMap;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return mData.size();
}
@Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return mData.get(arg0);
}
@Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return arg0;
}

public final class ViewHolder{
public TextView upload_log_tv;
}

String[] aStrings = new String[]{"BFT.xsl","P2C.xsl","2C.xsl","Hipot.xsl","SNT.xsl","BI/RI.xsl","FST.xsl","POD.xsl"};

public View getView(int arg0, View arg1, ViewGroup arg2) {
// TODO Auto-generated method stub
if(arg1 == null){
arg1 = mInflater.inflate(R.layout.listitem_create, null);
hoder = new ViewHolder();

hoder.upload_log_tv = (TextView) arg1.findViewById(R.id.upload_log);
mData.get((int) hoder.upload_log_tv.getTag()).put("path","");
hoder.upload_log_tv.setTag(arg0);
hoder.upload_log_tv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Integer pos = (Integer) arg0.getTag();
Map<String, Object> index = mData.get(pos);
index.put("path",aStrings[pos]);
}
});
arg1.setTag(hoder);
}else{
hoder = (ViewHolder)arg1.getTag();
}
return arg1;
}
}

你给list注册一个itemclick事件
点击的时候,会触发事件,你再取出对应的Textview做修改即可,这个代码有点多,没法贴出来

追问

我现在写的这个是子控件优先于listview的，因为我的Item中还包含了EditText,RadioGroup等，listview获取焦点无效，所以我现在是写成TextView的点击事件来要求响应，存入容器里的值Log信息打印正确，但是TextView却只有最后一个Item才变值了，前面的未有任何改变，不知道该如何改变对应的Textview的值？

可以获取焦点的，做下设置即可

不知道你想实现什么功能
