Try this adapter code:
public class IndividualsAdaptor extends ArrayAdapter {
protected Context mContext;
// Code for Custom Filter.
protected List mBackupList = new ArrayList();
public IndividualsAdaptor(Context context, List status) {
super(context, R.layout.t3, status);
mContext = context;
// Code for Custom Filter.
mBackupList.addAll(status);
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
if (convertView == null) {
convertView = LayoutInflater.from(mContext).inflate(R.layout.t3, null);
holder = new ViewHolder();
holder.usernameHomepage = (TextView) convertView.findViewById(R.id.fname);
holder.statusHomepage = (TextView) convertView.findViewById(R.id.lname);
holder.pposition = (TextView) convertView.findViewById(R.id.idposition);
holder.orgName = (TextView) convertView.findViewById(R.id.organizationname);
holder.logo = (ImageView) convertView.findViewById(R.id.imageView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
ParseObject statusObject = (ParseObject) getItem(position);
// title
String username = statusObject.getString("firstname");
holder.usernameHomepage.setText(username);
// content
String status = statusObject.getString("lastname");
holder.statusHomepage.setText(status);
// content
String positions = statusObject.getString("position");
holder.pposition.setText(positions);
// content
String org = statusObject.getString("organizationName");
holder.orgName.setText(org);
// logo
URL url = null;
Bitmap bmp = null;
try {
url = new URL("img hosting location" + statusObject.getString("image"));
bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
} catch (MalformedURLException e) {
}catch (IOException e) {
}
holder.logo.setImageBitmap(bmp);
Picasso.with(mContext)
.load(String.valueOf(url))
.into(((ImageView) convertView
.findViewById(R.id.imageView)));
return convertView;
}
public static class ViewHolder {
TextView usernameHomepage;
TextView statusHomepage;
TextView orgName;
TextView pposition;
ImageView logo;
}
// Code for Custom Filter.
@Override
public Filter getFilter() {return new Filter(){
@Override
protected FilterResults performFiltering(CharSequence charSequence) {
String queryString = charSequence.toString().toLowerCase();
List<ParseObject> filteredList = new ArrayList<>();
ParseObject tmpItem;
String tmpUsername, tmpStatus, tmpPositions, tmpOrg;
for(int i=0; i<mBackupList.size(); i++){
tmpItem = (ParseObject) mBackupList.get(i);
tmpUsername = tmpItem.getString("firstname").toLowerCase();
tmpStatus = tmpItem.getString("lastname").toLowerCase();

// The matching condition

filteredList.add(tmpItem);
}
}
FilterResults filterResults = new FilterResults();
filterResults.count = filteredList.size();
filterResults.values = filteredList;
return filterResults;
}
@Override
protected void publishResults(CharSequence charSequence, Filter.FilterResults filterResults) {
clear();
addAll((List<ParseObject>) filterResults.values);
}
};}
public void updateBackupList(List newList){
mBackupList.clear();
mBackupList.addAll(newList);
}
}
And Individuals.java:
public class Individuals extends ListFragment {
private List<ParseObject> mOrganization = new ArrayList<ParseObject>();
SearchView sv;
IndividualsAdaptor adaptor;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.individuals, container, false);
}
@Override
public void onViewCreated(View view, Bundle b) {
super.onViewCreated(view, b);
sv = (SearchView) view.findViewById(R.id.searchView1);
adaptor = new IndividualsAdaptor(getActivity(), mOrganization);
setListAdapter(adaptor);
ParseQuery.getQuery("_User").findInBackground(this);
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String text) {
return false;
}
@Override
public boolean onQueryTextChange(String text) {
adaptor.getFilter().filter(text);
return true;
}
});
}
@Override
public void done(List<ParseObject> scoreList, ParseException e) {
if (e == null) {
Log.d("score", "Retrieved " + scoreList.size() + " _User");
mOrganization.clear();
mOrganization.addAll(scoreList);
((IndividualsAdaptor) getListAdapter()).updateBackupList(mOrganization);
((IndividualsAdaptor) getListAdapter()).notifyDataSetChanged();
} else {
Log.d("score", "Error: " + e.getMessage());
}
}
}
回答2:
create a class variable for view
View view;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
view=inflater.inflate(R.layout.individuals, container, false);
return view;
}
use this for search view
SearchView searchView = (SearchView)view.findViewById(R.id.searchTextView);
This layout can be used.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:weightSum="1"
android:layout_height="match_parent">
<TextView android:id="@id/android:empty"
android:text="No data"
android:layout_width="match_parent"
android:layout_weight="0.1"
android:layout_height="0dp"
tools:ignore="HardcodedText" />
<SearchView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.1"
android:id="@+id/searchUserTextField"
android:background="@android:color/holo_red_dark"
android:textColor="@android:color/white"
android:textSize="14sp"
android:hint="Search by Name or Company"
android:textColorHint="#fff" />
<ListView android:id="@id/android:list"
android:layout_width="match_parent"
android:layout_weight="0.6"
android:layout_height="wrap_content"
/>
<ImageView
android:id="@+id/imageView7"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="0.2"
android:src="@mipmap/ic_launcher"/>
</LinearLayout>
回答3:
i think problem is here:
SearchView searchView = (SearchView)view.findViewById(R.id.searchTextView);
view=inflater.inflate(R.layout.individuals, container, false);
you are calling searchview before view created
