自定义adapter之后，oncreate里面想设置某一行为焦点，焦点皮肤为黄色，怎么设置呀？
要实现一个电视菜单，里面有四行，每一行有两个TextView和一个ProgressBar，
是不是只能使用自定义Adapter的形式来解决？ 貌似不能用SimpleAdapter。
下面是具体代码，显示已经显示出来了，焦点移动也没问题，但是就是没办法做到一开始的时候就设置某一个item为焦点，求指教怎么做到这点？ 另外， 设置selector也无效，不知道为什么。
public class MyAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private List<Map<String, Object>> mData;
private ViewHolder holder;
private TextView tView;
public MyAdapter(Context context, List<Map<String, Object>> data) {
this.mInflater = LayoutInflater.from(context);
this.mData = data;
}
@Override
public int getCount() {
return mData.size();
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (mData.get(position).get("type") == "text only") {
if(convertView == null){
convertView = mInflater.inflate(R.layout.text,null);
tView = (TextView) convertView.findViewById(R.id.tvMain);
convertView.setTag(tView);
}else{
tView = (TextView) convertView.getTag();
}
//赋值
tView.setText(mData.get(position).get("title").toString());
} else {
if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.pcsettings, null);
holder.setTvTitle((TextView) convertView
.findViewById(R.id.tvTitle));
holder.setPbProgressBar((ProgressBar) convertView
.findViewById(R.id.progressBar));
holder.setTvValue((TextView) convertView
.findViewById(R.id.tvValue));
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
// 给每一行赋值
holder.getTvTitle().setText(
mData.get(position).get("title").toString());
holder.getPbProgressBar().setProgress(
Integer.parseInt(mData.get(position).get("position")
.toString()));
holder.getTvValue().setText(
mData.get(position).get("position").toString());
}
return convertView;
}
}public class PCSettings extends ListActivity {
private List<Map<String, Object>> mData;
//自定义的Adapter类
private MyAdapter adapter;
@Override

super.onCreate(savedInstanceState);

getListView().setOnItemClickListener(listener);
}

listview?adapter?
[解决办法]
构造函数里面加个位置参数，new MyAdapter(context,list,int);通过int参数在adapter类里面实现你想要的功能
[解决办法]
getView中的position参数就是行数，你判断position的值，设置颜色不就行了？
if (position == ***)
convertView.setBackgroundColor(0xffff00);
