android spannable viewholder

Question

我正在编写一个应用程序，只是尝试在viewholder.My代码中获得一个可跨转的字符串，只是警察的颜色不会改变。我哪里错了？谢谢

public class MyListAdapter extends ArrayAdapter<String[]>{

int groupid;
List<String[]> items;
Context context;
String test;

public MyListAdapter(Context context, int vg, int id, List<String[]> items){
    super(context,vg, id, items);
    this.context=context;
    groupid=vg;
    this.items=items;
}
static class ViewHolder {
    public TextView textid;

    //public TextView textname;
    //public TextView txtadresse;

}
public View getView(final int position, View convertView, ViewGroup parent) {

    View rowView = convertView;
    if(rowView==null){
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        rowView= inflater.inflate(groupid, parent, false);
        ViewHolder viewHolder = new ViewHolder();
        viewHolder.textid = (TextView) rowView.findViewById(R.id.txtid);

        rowView.setTag(viewHolder);
    }

    // Fill data
    ViewHolder holder = (ViewHolder) rowView.getTag();
    String[] row=items.get(position);
    test = row[0].toString();
    Spannable pouf = new SpannableString(test);
    pouf.setSpan(new ForegroundColorSpan(Color.RED),0,5, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

    holder.textid.setText(pouf+" - "+row[1]+"\n"+row[2]);
    rowView.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v){
            String[] record = items.get(position);


            Intent intent=new Intent(context, Main3Activity.class);
            intent.putExtra("numéro", record[0]);
            intent.putExtra("localite", record[1]);
            intent.putExtra("adresse", record[2]);
            context.startActivity(intent);
        }

    });
    return rowView;


}
}

好吧，我自己找到了答案……我的错误是为span使用了concat，相反，我们必须使用Textutils来与spannable内容连接，以防有人会怀疑我发布了我的代码：

public class MyListAdapter extends ArrayAdapter<String[]>{

int groupid;
List<String[]> items;
Context context;
String test;
String test2;
String test3;

public MyListAdapter(Context context, int vg, int id, List<String[]> items){
    super(context,vg, id, items);
    this.context=context;
    groupid=vg;
    this.items=items;
}
static class ViewHolder {
    public TextView textid;


}
public View getView(final int position, View convertView, ViewGroup parent) {

    View rowView = convertView;
    if(rowView==null){
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        rowView= inflater.inflate(groupid, parent, false);
        ViewHolder viewHolder = new ViewHolder();
        viewHolder.textid = (TextView) rowView.findViewById(R.id.txtid);

        rowView.setTag(viewHolder);
    }

    // Fill data
    ViewHolder holder = (ViewHolder) rowView.getTag();
    String[] row=items.get(position);
    test = row[0].toString();
    test2 = row[1].toString();
    test3 = row[2].toString();
    SpannableString pouf = new SpannableString(test);
    pouf.setSpan(new RelativeSizeSpan(1.5f), 0, pouf.length(), 0);
    SpannableString pouf2 = new SpannableString(test2);
    pouf2.setSpan(new RelativeSizeSpan(1.5f), 0, pouf2.length(), 0);
    SpannableString pouf3 = new SpannableString(test3);
    pouf3.setSpan(new RelativeSizeSpan(1f), 0, pouf3.length(), 0);


    holder.textid.setText(TextUtils.concat(pouf," - ",pouf2,"\n",pouf3));
    rowView.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v){
            String[] record = items.get(position);


            Intent intent=new Intent(context, Main3Activity.class);
            intent.putExtra("numéro", record[0]);
            intent.putExtra("localite", record[1]);
            intent.putExtra("adresse", record[2]);
            context.startActivity(intent);
        }

    });
    return rowView;
