ListView repeating the data on load more

ListView repeating the data on load more - android

I am using on scroll to load more data and show them in list view but my ListView first shows already loaded data then adds the newly added data to ListView
I have used for reference this and many others but unable to solve the issue
Here is my activity class
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_all);
ButterKnife.bind(this);
Users = Users.getCurrentUser(this);
setSupportActionBar(toolbar);
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
}
UIUtility.setStatusColor(this);
Intent intent = getIntent();
try {
entityData = new JSONArray(intent.getStringExtra(EXTRA_DATA));
} catch (JSONException e) {
e.printStackTrace();
}
viewAllCategory = intent.getIntExtra(EXTRA_CATEGORY, 0);
viewAllEntityType = intent.getIntExtra(EXTRA_TYPE, 0);
latitude = intent.getDoubleExtra(EXTRA_LATITUDE, 0);
longitude = intent.getDoubleExtra(EXTRA_LONGITUDE, 0);
setTitle(TITLES[viewAllCategory]);
if (viewAllEntityType == Constants.SMBEntityType.TYPE_USER) {
List<Users> users = Utility.convertJsonArrayToUsers(entityData);
adapterUser = new ViewAllUserAdapter(this, users);
lvEntity.setAdapter(adapterUser);
} else {
List<Book> books = Utility.convertJsonArrayToBook(entityData);
adapterBook = new ViewAllBookAdapter(this, books);
lvEntity.setAdapter(adapterBook);
}
lvEntity.setOnScrollListener(new AbsListView.OnScrollListener() {
#Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}
#Override
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
if (!stopLoadingMore) {
if (totalItemCount == firstVisibleItem + visibleItemCount && !isLoading) {
isLoading = true;
showLoading();
loadMoreData();
}
}
}
});
}
private void loadMoreData() {
String loadMoreUrl = buildLoadMoreUrl();
ShareMyBookHttpClient client = new ShareMyBookHttpClient();
client.get(loadMoreUrl, new AsyncHttpResponseHandler() {
#Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
hideLoading();
if (responseBody != null) {
start = start+20;
try {
JSONObject jo = new JSONObject(new String(responseBody));
if (!jo.getBoolean(Constants.JsonKeys.ERROR)) {
JSONArray data = jo.getJSONArray(Constants.JsonKeys.DATA);
if (data.length() == 0) {
stopLoadingMore = true;
return;
}
if (data.length() < 20) {
stopLoadingMore = true;
}
for (int i = 0; i < data.length(); i++) {
entityData.put(data.getJSONObject(i));
}
if (viewAllEntityType == Constants.SMBEntityType.TYPE_USER) {
List<Users> users = Utility.convertJsonArrayToUsers(entityData);
adapterUser.mergeArray(users);
} else {
List<Book> books = Utility.convertJsonArrayToBook(entityData);
adapterBook.mergeArray(books);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
#Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
hideLoading();
}
});
}
private String buildLoadMoreUrl() {
switch (viewAllCategory) {
default:
case ViewAllCategory.CATEGORY_USER:
return Constants.createUrlToGetViewAllUsers(Users.getId(), latitude, longitude, Users.getAuthToken(), start, LIMIT);
case ViewAllCategory.CATEGORY_MY_BOOKS:
return Constants.createUrlToGetViewAllMyBooks(Users.getId(), Users.getAuthToken(), start, LIMIT);
}
}
private void showLoading() {
sbLoading = Snackbar.make(coolMain, R.string.view_all_loading, Snackbar.LENGTH_INDEFINITE);
sbLoading.show();
}
private void hideLoading() {
isLoading = false;
if (sbLoading != null) {
sbLoading.dismiss();
}
}
and following is my AdapterClasss
public class ViewAllUserAdapter extends BaseAdapter {
private List<Users> users;
private Context context;
public ViewAllUserAdapter(Context context, List<Users> usersData) {
this.context = context;
users = usersData;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row=convertView;
UserVH holder=null;
if(row==null) {
LayoutInflater inflater = LayoutInflater.from(context);
row= inflater.inflate(R.layout.list_item_view_all_user, parent, false);
holder = new UserVH(row, position);
Users user = users.get(position);
UIUtility.setUserProfileUsingPicasso(context, user.getProfileImageUrlSmall(), holder.ivUserImage);
holder.tvName.setText(user.getName());
if (user.getDistance() == -1) {
holder.tvDistance.setText("");
} else {
holder.tvDistance.setText(context.getString(R.string.distance_notation, user.getDistance()));
}
row.setTag(holder);
}
else {
holder=(UserVH)row.getTag();Users user = users.get(position);
UIUtility.setUserProfileUsingPicasso(context, user.getProfileImageUrlSmall(), holder.ivUserImage);
holder.tvName.setText(user.getName());
if (user.getDistance() == -1) {
holder.tvDistance.setText("");
} else {
holder.tvDistance.setText(context.getString(R.string.distance_notation, user.getDistance()));
}
}
return row;
}
#Override
public int getCount() {
return users == null ? 0 : users.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
public void mergeArray(List<Users> additionalUsers) {
Log.e("users", String.valueOf(additionalUsers.size()));
if (additionalUsers != null) {
for (int i = 0; i < additionalUsers.size(); i++) {
if(!(users.contains(additionalUsers.get(i)))) {
users.add(additionalUsers.get(i));
}
}
}
notifyDataSetChanged();
}
public class UserVH extends View {
#Bind(R.id.item_vau_iv_user_image)
ImageView ivUserImage;
#Bind(R.id.item_vau_tv_name)
TextView tvName;
#Bind(R.id.item_vau_tv_distance)
TextView tvDistance;
private int position;
public UserVH(View view, final int position) {
super(context);
this.position = position;
ButterKnife.bind(this, view);
view.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
UIUtility.openUserDetailActivity(context, users.get(position));
}
});
}
}
}

As you already referred this link, Exactly the same issue is happening with you, You should have correct implementation for holder class in getView method.
Update your getView() method as per below :
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row=convertView;
UserVH holder=null;
if(row==null) {
LayoutInflater inflater = LayoutInflater.from(context);
row= inflater.inflate(R.layout.list_item_view_all_user, parent, false);
holder = new UserVH(row, position);
row.setTag(holder);
}
else {
holder=(UserVH)row.getTag();
}
Users user = users.get(position);
UIUtility.setUserProfileUsingPicasso(context, user.getProfileImageUrlSmall(), holder.ivUserImage);
holder.tvName.setText(user.getName());
if (user.getDistance() == -1) {
holder.tvDistance.setText("");
} else {
holder.tvDistance.setText(context.getString(R.string.distance_notation, user.getDistance()));
}
return row;
}
And update your getItemId and getItem methods as per below :
#Override
public Object getItem(int position) {
return users.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
EDIT : clear the list additional users before adding the new objects
public void mergeArray(List<Users> additionalUsers) {
Log.e("users", String.valueOf(additionalUsers.size()));
if (additionalUsers != null) {
// Following line to be added
additonalusers.clear();
for (int i = 0; i < additionalUsers.size(); i++) {
if(!(users.contains(additionalUsers.get(i)))) {
users.add(additionalUsers.get(i));
}
}
}
notifyDataSetChanged();
}

Your implementation of following methods is incorrect.
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
Change them as below
#Override
public Object getItem(int position) {
return users.get(position);
}
#Override
public long getItemId(int position) {
return position;
}

custom Adapter not working properly after filter applied in android

There is adapter set to Station(Name/Code) AutocompleteTextView. First time whole list is setting. After that If I filter for ch, It will display all filtered Items.
And Now If i remove ch, It will display whole list. Here there is no problem.
But Now If click back button or navigate tot other screen and coming to this screen again, there is only filtered Items are displaying(which are starts with ch).
Why only filtered Items are showing?
Please help me.

How to disable previous items in a ListView

I am trying to develop an activity where there is a custom listView made out of CustomAdapter.
The list consists of a TextView and an EditText. The EditText when clicked, it auto fetches the system time.
What I want is when a particular EditText is filled, I want all the previous(above) list items in the sequence to be disabled.
So far, I have tried using isEnabled() and areAllItemsEnabled() functions returning respective boolean values using position, but however didn’t work.
Please help me achieve the above.
Thanks.
This is my CustomAdapter Class
public class SelectStnListByRoute extends BaseAdapter implements View.OnClickListener {
Context context;
ArrayList<StnNames> stnList;
LayoutInflater layoutInflater = null;
ViewHolder viewHolder;
private int mLastClicked;

public String getCurrentTime(){
Calendar calendar = Calendar.getInstance();
SimpleDateFormat mdformat = new SimpleDateFormat("HH:mm:ss");

}
}

You can do this as below mentioned -:
You need to store the position of clicked button was. So initialize a variable in your class
int mButtonSelected = -1;
EDIT 1.
Then make a change to your isEnabled method
#Override
public boolean isEnabled(int position) {
if(position<mButtonSelected){
return false;
}
return true;
}
That will work it if any other button was clicked. but you have to do that in your onClick
mButtonSelected = position;
notifyDataSetChanged();
Let me it worked or not
EDIT
see below changes in your code-:
public class SelectStnListByRoute extends BaseAdapter {

In your code, your are calling something like list.get(1) but list size is 1. So, you can only call list.get(0). You are trying to reach to the non-existence objects.

The java.lang.IndexOutOfBoundsException means:
You have an ArrayList which has 1 element so you can only get the element at position 0.
But here, you're trying to access to the element at position 1 which is impossible because it does not exists.
The problem is probably here:
#Override
public void onResume() {
super.onResume();
try {
if (!feedList.isEmpty())
setAllSlidingAnimation(feedList.size());
...
}
If the size of feedList is 1, you will try to access to the SECOND element (first is at position 0, second is at position 1 == feedList.size()).

hide section labels in listview

I use component android-section-list (http://code.google.com/p/android-section-list/) to create sections in my listView. How can I hide sections after push some button?
I try to do like

switch(v.getId()) {

View convertView = inflater.inflate(R.layout.market_list_separator, null, false);

separatorLayout.setVisibility(View.GONE);
sectionAdapter.notifyDataSetChanged();
setButtonState(sortByTitle);
adapter.sort((Comparator<SectionListItem>) sortByTitle());
break;
}
}

My adapter put data in list rows and SectionListAdapter draw sections.

Where can I put check for visibility in this Adapter?

This works but will be overwritten by the getView() method in the adapter . You must handle this in the adapter bcoz each time view becomes visible on the screen the View is updated so becomes visible in your case.
For the Data you are storing add a Visibility field ( by default keep it visible ) and change the Visibility to GONE in the onClick() method.
if you dont understand , post me your code and will let you know what changes to make.
