I am using the StickyListHeadersListView android library from github for my application. It was working fine. After I implement MultiChoiceMode listener for copying and deleting elements, there is a problem in highlighting of elements.
Whenever I select an element and scroll up and down, some Section Headers are highlighted automatically like shown in the image below
How to avoid this behaviour. Is there any steps I'm missing? Need some hand in resolving the issue.
My Adapter which extends the StickyListHeadersAdapter is given below
public class MessageStickyAdapter extends BaseAdapter implements StickyListHeadersAdapter, SectionIndexer {
private final Context mContext;
private List<Msg> messages;
private int[] mSectionIndices;
private String[] mSectionDates;
private LayoutInflater mInflater;

mContext = context;
mInflater = LayoutInflater.from(context);
messages = listMessages;
mSectionIndices = getSectionIndices();
mSectionDates = getSectionDates();
}
private int[] getSectionIndices() {
ArrayList<Integer> sectionIndices = new ArrayList<>();
String lastDate = messages.get(0)._msg_date;
sectionIndices.add(0);
for (int i = 1; i < messages.size(); i++) {
if (!messages.get(i)._msg_date.equalsIgnoreCase(lastDate)) {
Log.d("LastDate,Newdate",lastDate + ',' +messages.get(i)._msg_date);
lastDate = messages.get(i)._msg_date;
sectionIndices.add(i);
}
}
int[] sections = new int[sectionIndices.size()];
for (int i = 0; i < sectionIndices.size(); i++) {
sections[i] = sectionIndices.get(i);
}
Log.d("Sections",String.valueOf(sections.length));
return sections;
}
private String[] getSectionDates() {
String[] dates = new String[mSectionIndices.length];
for (int i = 0; i < mSectionIndices.length; i++) {
dates[i] = messages.get(i)._msg_date;
Log.d("Dates",dates[i]);

I search in google and in stackoverflow all solution talk about Override
`getViewTypeCount` and `getItemViewType` and other solution not helped me
i see my code its correct but why its repeat or reorder item when scroll on
ListView
Because your item views appear to change based on the type of items in the list, you cannot cache your viewholder.
Try removing your if (convertView == null) { and accompanying else { statement.
This question has been asked so many times, but none of the solutions solved my issue.
I have an activity with two fragments with a viewpager, And each fragment has a listview. Upon moving between tabs my listview's items are repeating.
here is the adapter code.
public class ComboMenuAdapter extends BaseAdapter {
private Context mContext;
private MenuHolder mMenuHolder;
private ArrayList<Integer> index;
public ComboMenuAdapter(Context mContext, ArrayList<Integer> index) {
this.index = index;
this.mContext = mContext;
}
#Override
public int getCount() {
return index.size();
}
#Override
public MenuHolder getItem(int position) {
return DataHandler.getInstance().getData(index.get(position));
}
#Override
public long getItemId(int position) {
return position;
}
private class Holder {
ImageView image;
TextView price, liters, itemnametxt, mAdd_txt, minus, plus, counter;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final Holder mHolder;
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v= vi.inflate(R.layout.combo_meals_adapter, null);
mHolder = new Holder();
mHolder.price = (TextView) v.findViewById(R.id.price);
mHolder.itemnametxt = (TextView) v.findViewById(R.id.itemnametxt);
mHolder.image = (ImageView) v.findViewById(R.id.image);
mHolder.liters = (TextView) v.findViewById(R.id.ml);
mHolder.mAdd_txt = (TextView) v.findViewById(R.id.addtxt);
mHolder.minus = (TextView) v.findViewById(R.id.minus);
mHolder.counter = (TextView) v.findViewById(R.id.count);
mHolder.plus = (TextView) v.findViewById(R.id.plus);
v.setTag(mHolder);
} else {
mHolder = (Holder) v.getTag();
}
mMenuHolder = getItem(position);
mHolder.itemnametxt.setText(mMenuHolder.getItemname());
mHolder.image.setImageResource(R.mipmap.ic_launcher);
mHolder.price.setText(mMenuHolder.getItemprice());
mHolder.counter.setText(mMenuHolder.getItemCount());
return v;
}
}
I am unable to find the mistake, please help me, Thank you in advance.
Here, I am storing the data using DataHandler Class
public class DataHandler {
ArrayList<MenuHolder> listOfItemsFromJson = new ArrayList<MenuHolder>();
private static DataHandler mInstance = null;
static public DataHandler getInstance() {
if (null == mInstance) {
mInstance = new DataHandler();
}
return mInstance;
}
public DataHandler() {
listOfItemsFromJson = new ArrayList<>();
}
public ArrayList<MenuHolder> getListOfItemsFromJson() {
return listOfItemsFromJson;
}
public void clearList() {
listOfItemsFromJson.clear();
}
public void addData(MenuHolder holder) {
listOfItemsFromJson.add(holder);
}
public MenuHolder getData(int position) {
return listOfItemsFromJson.get(position);
}
public void removeData(int position) {
listOfItemsFromJson.remove(getData(position));
}
public void modifyData(MenuHolder holder, int position) {
listOfItemsFromJson.set(position, holder);
}
public int size() {
return listOfItemsFromJson.size();
}
}
Upon onCreateView(), I am placing the data
for (int i = 0; i < DataHandler.getInstance().size(); i++) {
if (DataHandler.getInstance().getData(i).isCombo()) {
DataHandler.getInstance().removeData(i);
}
}
for (int i = 0; i < 3; i++) {
MenuHolder mMenuHolder = new MenuHolder();
mMenuHolder.setItemname(itemNames[i]);
mMenuHolder.setImageName("#mipmap/ic_launcher");
mMenuHolder.setItemCount("0");
mMenuHolder.setItemprice("500");
mMenuHolder.setUserSeleted(false);
mMenuHolder.setCombo(true);
mMenuHolder.setDrinks(false);
mMenuHolder.setBiryani(false);
DataHandler.getInstance().addData(mMenuHolder);
}
index.clear();
for (int i = 0; i < DataHandler.getInstance().size(); i++) {
if (DataHandler.getInstance().getListOfItemsFromJson().get(i).isCombo()) {
index.add(i);
}
}
mCombosAdapter = new ComboMenuAdapter(getActivity(), index);
mlistView.setVisibility(View.VISIBLE);
mlistView.setAdapter(mCombosAdapter);
mlistView.setOnItemClickListener(this);
mMenuHolder = getItem(position);
should be retrieved before setting the data. Move it outside the if/else logic before.
mMenuHolder = getItem(position);
mHolder.itemnametxt.setText(mMenuHolder.getItemname());
mHolder.image.setImageResource(R.mipmap.ic_launcher);
mHolder.price.setText(mMenuHolder.getItemprice());
mHolder.counter.setText(mMenuHolder.getItemCount());
you want to retrieve the item at position before filling up your view
Make sure you clear your adapter before adding new objects to it:
if (!someAdapter.isEmpty())
someAdapter.clear();
someAdapter.addAll(new ArrarList(arrayListContainingUpdatedStuff));
No need for a new adapter allocation, you might lose you reference to the old one and the list might go blank.
Hope this helps.
for this code you get Repeating data may be
for (int i = 0; i < 3; i++)
{
MenuHolder mMenuHolder = new MenuHolder();
mMenuHolder.setItemname(itemNames[i]);
mMenuHolder.setImageName("#mipmap/ic_launcher");
mMenuHolder.setItemCount("0");
mMenuHolder.setItemprice("500");
mMenuHolder.setUserSeleted(false);
mMenuHolder.setCombo(true);
mMenuHolder.setDrinks(false);
mMenuHolder.setBiryani(false);
DataHandler.getInstance().addData(mMenuHolder);
}

you have to use courseAdapter.notifyDataSetChanged() after setting customViewHolder.spinner.setAdapter(courseAdapter);
Hope this helps.
I have a problem with the list. My list consists of two rows. The first is simply information about the object. When I click on the first item is presented a second row. It has a timer, everything works as expected, but the re-acquired by the time starts ticking faster. I understand that it is necessary to clean the list or am I just doing something wrong. Help me please.

I solved the problem and I want to share with you the ready code.
When creating a new timer I dobovlyaet it to your array of, and with the second click on an element and find this timer is reset to zero it. Although at this point I'm going to send data to the server to zero. Generally it works, check!

I have a ListView which is having 2 types of headers & within this I want to implement another type of header known as StickyListHeader
Well, Implementing 2 types of header was a complex task for me & now within that implementing StickyListHeader is not an easy task. Let for every 5th view I have to add a StickyListHeader.
This is the code :
public class ContentsFragment extends ListFragment implements OnTouchListener,AbsListView.OnScrollListener {
private MyCustomAdapter mAdapter;
Activity temp = getActivity();
String []s = new String[500];
ArrayList<GS> q = new ArrayList<GS>();
ListView lv;
int count=0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
DBAdapter db = DBAdapter.getDBAdapter(getActivity());
if (!db.checkDatabase())
db.createDatabase(getActivity());
db.openDatabase();
q = db.getData();
mAdapter = new MyCustomAdapter(getActivity());
mAdapter.addSeparatorItem(new ContentWrapper(q.get(0).getA_name(),null,null));
mAdapter.addItem(new ContentWrapper(q.get(0).getAS_name(), q.get(0).getDesc_art(),null));
for (int i = 1; i <= 14; i++) {
if (!(q.get(i).getA_name().trim().equals(q.get(i-1).getA_name().trim()))) {
mAdapter.addSeparatorItem(new ContentWrapper(q.get(i).getA_name(), null,null));
}
if(!(q.get(i).getExtra()==null))
mAdapter.addGraySeparatorItem(new ContentWrapper(q.get(i).getExtra(),null,null));
mAdapter.addItem(new ContentWrapper(q.get(i).getAS_name(), q.get(i).getDesc_art(),null));
}
for (int i = 15; i < 36; i++) {
if (!(q.get(i).getA_name().trim().equals(q.get(i-1).getA_name().trim()))) {
mAdapter.addSeparatorItem(new ContentWrapper(q.get(i).getA_name(), null,null));
}
if(!(q.get(i).getExtra()==null))
mAdapter.addGraySeparatorItem(new ContentWrapper(q.get(i).getExtra(),null,null));
mAdapter.addItem(new ContentWrapper(q.get(i).getAS_name(), q.get(i).getDesc_art(),null));
}

As you can see for StickyListHeader I implemented onScroll() method .
Now I think in the modification have to be done in class MyCustomAdapter constructor & in also getView() method beacuse I am follwing this example & it states that we have to deal with constructor,getView() & onScroll().
Can anyone tell me what should I modify to accomplish my task.
Thank You
For Header Listview you should use HeaderListView OR PinnedHeaderListView Library.very easy to use.
