我想用自己喜欢的选项做一个自定义列表视图，事情是，当我添加一些项目收藏夹，然后向下滚动fav按钮更改顺序随机，另一件事我需要帮助的是，我不知道如何改变喜爱的ImageView点击等时（因为你只能有1喜爱的选项）ImageView里面的项目在ListView中的变化的随机
这是我的自定义适配器
public class LineasAdapter extends BaseAdapter {
Context context;
protected List<Lineas> lineas;
LayoutInflater inflater;
public LineasAdapter(Context context, List<Lineas> lista){
this.context = context;
this.inflater = LayoutInflater.from(context);
this.lineas = lista;
}
@Override
public int getCount() {
return lineas.size();
}
@Override
public Object getItem(int position) {
return lineas.get(position);
}
@Override
public long getItemId(int position) {
return 0;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = this.inflater.inflate(R.layout.item_lista,
parent, false);
holder.numero = (TextView) convertView
.findViewById(R.id.number);
holder.titulo = (TextView) convertView
.findViewById(R.id.titulo);
holder.subtitulo = (TextView) convertView
.findViewById(R.id.subtitulo);
holder.star = (ImageView) convertView
.findViewById(R.id.star);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
Lineas linea = lineas.get(position);
holder.numero.setText(linea.numero_s());
holder.titulo.setText(linea.titulo());
holder.subtitulo.setText(linea.subtitulo());
final SharedPreferences.Editor editor = convertView.getContext().getSharedPreferences("Favorito",0).edit();
final int numero = linea.numero();
final Context c = convertView.getContext();
final ImageView estrella = holder.star;
/** this is where I change my fav button and add the number to some sharedpreferences **/
holder.star.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
editor.putInt("linea", numero);
editor.commit();
Toast.makeText(c,"Has agregado a favoritos a el cole numero "+String.valueOf(numero), Toast.LENGTH_SHORT).show();
estrella.setImageResource(R.drawable.star);
}
});
return convertView;
}
private class ViewHolder {
TextView numero;
TextView titulo;
TextView subtitulo;
ImageView star;
}
}
