如何从以下设计中进行过滤器概念？我在这里附上了两个屏幕设计。
- 仪表板片段 -> 具有带有基本适配器的 Listview。
上面的ListView代码如下
仪表板重构
public class DashBoardRefactor extends Fragment {
public static ProgressDialog progress;
public static List<DashListModel> dashRowList1 = new ArrayList<DashListModel>();
public static View footerView;
// @Bind(R.id.dashListView)

dashListView = (ListView) v.findViewById(R.id.dashListView);
footerView = ((LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.dashboard_list_footer, null, false);
dashListView.addFooterView(footerView);
footerView.setVisibility(View.GONE);
dashRowList1.clear();
dashboardViewTask();
dashListView.setOnScrollListener(new EndlessScrollListener(getActivity(), dashListView, footerView));
return v;
}
public void dashboardViewTask() {
progress.setMessage("Loading...");
progress.setCanceledOnTouchOutside(false);
progress.setCancelable(false);
progress.show();
// footerView.setVisibility(View.VISIBLE);
Map<String, String> params = new HashMap<String, String>();
Log.e("candidate_id", "candidate_id---->" + SessionStores.getBullHornId(getActivity()));
params.put("candidate_id", SessionStores.getBullHornId(getActivity()));
params.put("employmentPreference", SessionStores.getEmploymentPreference(getActivity()));
params.put("page", "1");
new DashBoardTask(getActivity(), params, dashListView, footerView);
}
@Override
public void onCreateOptionsMenu(
Menu menu, MenuInflater inflater) {
if (menu != null) {
menu.removeItem(R.id.menu_notify);
}
inflater.inflate(R.menu.menu_options, menu);
MenuItem item = menu.findItem(R.id.menu_filter);
item.setVisible(true);
getActivity().invalidateOptionsMenu();
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.his__menu_accept:
Toast.makeText(getActivity(), "clicked dashboard menu accept", Toast.LENGTH_LONG).show();
return true;
case R.id.menu_filter:
// click evnt for filter

澄清：
- 如何在单击仪表板片段上的筛选按钮时进行筛选。请建议方法。我在这里也附上了我的过滤器设计。
Dashboard Fragment--> Filter Button-> Filter screen-> 过滤后的结果应该在 DashBoard Fragment 上查看。
单击应用按钮后，根据过滤器屏幕的输入，它会过滤列表视图，结果来自后端团队。我必须在仪表板片段上显示该结果。
请澄清这个过滤器的概念。
