我在一个活动屏幕上有3个“回收者视图”，并具有对应的适配器。在“活动”屏幕上，我有一个“应用”按钮。在每个适配器上，我都有一个带有值的微调器。现在，我想从适配器的微调器中选择一个项目，然后单击活动上的按钮，我要过滤“回收者”视图中提供的列表。以下是带有微调器的适配器的代码：
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder viewHolder, int i) {
final ViewHolder myViewHolder = (ViewHolder) viewHolder;
final Department_model model = models_list.get(i);
myViewHolder.text.setText("Department");
String items[] = new String[models_list.size()];
Set<String> Dep_list = new HashSet<String>();
for (int j = 0; j < items.length; j++) {
Dep_list.add((items[j]));
Dep_list.remove(null);
String ID[]= new String[models_list.size()];
ID[j] = models_list.get(j).getDepartment_ID();
items[j] = models_list.get(j).getDepartment_Name();
String[] unique = new HashSet<String>(Arrays.asList(items)).toArray(new String[0]);
spinnerArrayAdapter = new ArrayAdapter<String>(context, R.layout.department_list, unique);
spinnerArrayAdapter.setDropDownViewResource(R.layout.category_list);
myViewHolder.spinner.setAdapter(spinnerArrayAdapter);
}
myViewHolder.spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String Department_item = parent.getItemAtPosition(position).toString();
long Department_id = parent.getItemIdAtPosition(position);
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
请有人说明我该怎么做。帮助将不胜感激。谢谢！
