Hello, okay?
My question is that I can not do a search on my facebook friends in my
listview using a basedapter ...
My doubt is that the same topic But no solution yet!
Follow my code below
/*
* callback after friends are fetched via me/friends.
* Chamada dos amigos atraves do me/friends
*/
public class FriendsRequestListener extends BaseRequestListener {
@Override
public void onComplete(final String response, final Object state) {
dialog.dismiss();
try{
arrayName = new ArrayList<String>();
jsonArray = new JSONObject(response).getJSONArray("data");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject json_data = jsonArray.getJSONObject(i);
if(json_data.has("name")){
String getFriendName = json_data.getString("name");
arrayName.add(getFriendName);
}else{
String getFriendName = null;
arrayName.add(getFriendName);
}
}
}catch(JSONException e){
Log.d(TAG, e.getMessage());
return;
}
stringName = new String[arrayName.size()];
stringName = arrayName.toArray(stringName);
EscolhaAmigosFacebook.this.runOnUiThread(new Runnable() {
@Override
public void run() {
adapter = new FriendListAdapter(EscolhaAmigosFacebook.this, stringName,
arrayName);
friendsListView.setTextFilterEnabled(true);
friendsListView.setAdapter(adapter);
}
});
}
/**
* Definition of the list adapter
*/
public class FriendListAdapter extends BaseAdapter implementsFilterable {
String[] fetFriendName;
List<String> arrayList;
List<String> mOriginalValues;
LayoutInflater mInflater = null;
EscolhaAmigosFacebook friendsList;
FriendListAdapter(EscolhaAmigosFacebook friendsList, String[]
stringName, ArrayList<String> arrayName) {
this.friendsList = friendsList;
if (Utility.model == null) {
Utility.model = new FriendsGetProfilePics();
}
Utility.model.setListener(this);
fetFriendName = stringName;
arrayList = new ArrayList<String>();
mOriginalValues = arrayName;
mInflater = LayoutInflater.from(friendsList.getBaseContext());
}
@Override
public int getCount() {
return mOriginalValues.size();
}
@Override
public Object getItem(int position) {
return mOriginalValues.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup
parent) {
JSONObject jsonObject = null;
final ViewHolder holder;
View vi = convertView;
try {
jsonObject = jsonArray.getJSONObject(position);
} catch (JSONException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
if (vi == null) {
vi = mInflater.inflate(R.layout.friend_item, null);
holder = new ViewHolder();
holder.profile_pic = (ImageView) vi.findViewById(R.id.
profile_pic);
TextView txtFriendsName = (TextView)vi.findViewById(R.id.
name);
txtFriendsName.setText(fetFriendName[position]);
vi.setTag(holder);
}else{
holder = (ViewHolder) vi.getTag();
}
try {
holder.profile_pic.setImageBitmap(Utility.model.getImage(
jsonObject.getString("id"), jsonObject.getString("picture"
)));
} catch (JSONException e) {
holder.name.setText("");
}
return vi;
}
@Override
public Filter getFilter() {
Filter filter = new Filter(){
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
arrayList = (List<String>) results.values;
notifyDataSetChanged();
}
@Override
protected FilterResults performFiltering(CharSequence
constraint) {
FilterResults results = new FilterResults();
List<String> FilteredArrList = new ArrayList<String>();
if (constraint == null || constraint.length() == 0) {
results.count = mOriginalValues.size();
results.values = mOriginalValues;
} else {
constraint = constraint.toString();
for (int i = 0; i < mOriginalValues.size(); i++) {
String data = mOriginalValues.get(i);
if(data.toLowerCase().startsWith(constraint.toString())) {
FilteredArrList.add(data);
}
}
results.count = FilteredArrList.size();
results.values = FilteredArrList;
}
return results;
}
};
return filter;
}
}
private TextWatcher filterTextWatcher = new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int
before, intcount) {
adapter.getFilter().filter(s.toString());
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
}
};
I can not find the solution, just when I type something in my textview,
nothing happens in the listview, not filter type ...
If anyone also know what I do to see where the error might be, please ..
If anyone can help me!
