How to access the ArrayList present in Adapter in Activity

How to access the ArrayList present in Adapter in Activity - android

I have a listview in which in each row I have a checkbox along with details o persons. Now on clicking checkboxes, I want to store the id of those persons in arrayList which I am able to store but the arrayList id in adapter. I want to access the arrayList in activity because I want to take a button in activity on clicking which I want to send ids of all the selected persons to another activity. How do I do that.
My code is below:

Create one method in adapter like
public class SendWorkAdapter extends BaseAdapter {
public List<SendWorkRow> getAllWorkRows() {
return send_work_array_list;
}
}
and access this method using adapter instance in activity.
Another way is you can write a method in Adapter where you will find all selected ids in a List and return. So whenever you will require list of selected ids, call this method from Activity and do your task. like
public class SendWorkAdapter extends BaseAdapter {
public List<SendWorkRow> getAllSelectedWorkRows() {
// write your logic to find selected rows
return result;
}
}

search in listview only refreshes the whole list and does not get the result into list

I am getting the data from server using JSON and when i try to search in the listview it just refreshes the whole list and does not narrate it, but when i debug i can see the result on getfilter is right right and it drugsFiltered = (ArrayList<drugs_json_data>) results.values; does have the filtered data inside it. just the listview.setadaptor is being done inside onPostExecute of the asynctask.
here is my adapter code:
public class drugs_adaptor_listView extends ArrayAdapter<drugs_json_data> implements Filterable {
ArrayList<drugs_json_data> drugs;
ArrayList<drugs_json_data> drugsFiltered;

int resource;
public drugs_adaptor_listView(Context context, int resource, ArrayList<drugs_json_data> drugs) {
super(context, resource, drugs);
this.drugs = drugs;
this.drugsFiltered = drugs;
this.context = context;
this.resource = resource;

In getView method in Adapter
Replace

Filter Reset automatically when backpress

I am facing one issue in android filter.
First of all I search some text and on the resulted value I am doing one event and come back to the activity. Once I come back that time my listview will refresh with all item rather then filtered item.
For example :
I am searching one contact from contact book and it will return some result. On that result I will do some functionality and then come back to contact listing screen that time my contact list reset automatically.
Below is the code of filter
public class ValueFilter extends Filter {
ContactsAdapter adapter;
private ArrayList<HashMap<String, Object>> mfilterList;
public ValueFilter(ArrayList<HashMap<String, Object>> filterList, ContactsAdapter adapter) {
this.adapter = adapter;
this.mfilterList = filterList;
}
//Invoked in a worker thread to filter the data according to the constraint.
#Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
if (constraint != null && constraint.length() > 0) {
ArrayList<HashMap<String, Object>> filterListbk = new ArrayList<HashMap<String, Object>>();
for (int i = 0; i < mfilterList.size(); i++) {
String contactName = (String) mfilterList.get(i).get(Contacts.CONTACTKEY);
String contactNo = (String) mfilterList.get(i).get(Contacts.DURATION);
contactName = contactName.toLowerCase();
constraint = (CharSequence) constraint.toString().toLowerCase();
if (contactName.contains(constraint)) {
filterListbk.add(mfilterList.get(i));
}
if (contactNo.contains(constraint)) {
filterListbk.add(mfilterList.get(i));
}
results.count = filterListbk.size();
results.values = filterListbk;
}
} else {
results.count = mfilterList.size();
results.values = mfilterList;
}
return results;
}
//Invoked in the UI thread to publish the filtering results in the user interface.
#SuppressWarnings("unchecked")
#Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
// adapter.players= (ArrayList<Player>) results.values;
adapter.Books = (ArrayList<HashMap<String, Object>>) results.values;
String new_result = results.values.toString();
if(!new_result.equals(null)){
adapter.Books = (ArrayList<HashMap<String, Object>>) results.values;
adapter.notifyDataSetChanged();
Intent intent = new Intent();
intent.setAction(SipManager.ACTION_NO_RECORD_FOUND);
Bundle args = new Bundle();
args.putSerializable("result",(Serializable)adapter.Books);
args.putSerializable("flag","0");

How to do Filter listview in android?

How to do the Filter concept from Below design? I here by attached two screen designs.
DashBoard Fragment -> Having Listview with Base adapter.
The above ListView code is given Below
DashBoardRefactor
public class DashBoardRefactor extends Fragment {
public static ProgressDialog progress;
public static List<DashListModel> dashRowList1 = new ArrayList<DashListModel>();

Clarification:
How do to Filter while click the Filter Button On DashBoard Fragment. Please Suggest the way. I here by attached My Filter design also.
Dashboard Fragment--> Filter Button-> Filter screen-> the Filtered results should view on DashBoard Fragment.
Once click the apply Button Based on the input from Filter screen it filters the list view the result comes from back end team. I have to display that result on Dashboard Fragment.
Kindly please clarify this Filter concept.

Android update adapter doesn't work correctly

In this code I have a custom adapter, and after I add new data into ArrayList my adapter.notifyDataSetChanged(); doesn't work.

My custom Adapter code is this:
public class ReceivedAdapter extends ArrayAdapter<ReceivedItemStructure> {
private ArrayList<ReceivedItemStructure> list;
public ReceivedAdapter(Context c, ArrayList<ReceivedItemStructure> items) {
super(c,0,items);
list = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ReceiveItemView itemView = (ReceiveItemView)convertView;
if (null == itemView)
itemView = ReceiveItemView.inflate(parent);
itemView.setItem(getItem(position));
return itemView;
}
public void update(ArrayList<ReceivedItemStructure> items) {
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
addAll(items);
} else {
for (ReceivedItemStructure item : items) {
add(item);
}
}
}
}
setListAdapter(adapter); works correctly and I don't have any problem, but after I add new data into items notifyDataSetChanged it doesn't work.
My manifest content:
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="21"/>

it is the super class that is handling the dataset, since you are not overriding getCount and getItem,
public void update(ArrayList<ReceivedItemStructure> items) {
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
addAll(items);
} else {
for (ReceivedItemStructure item : items) {
add(item)
}
}
}
addAll was introduced with Honeycomb, so you probably want to check the current supported sdk where you are app is running

You are modifying your original items collection. But you should to modify adapter's data. Use ArrayAdapter.add method to add new items.

listview does not updates

I am expirience wierd situation because my list view updates only once.
The idia is following, i want to download posts from web, which are located on page 3 and page 5 and show both of them on listview. However, List view shows posts only from page 3. MEanwhile, log shows that all poast are downloded and stored in addList.
So the problem - objects from second itteration are not shown in listview. Help me please to fix this issue.

I think the problem is you aren't calling the super class of notifyDataSetChanged(), maybe try
#Override
public void notifyDataSetChanged() {
rows.clear();
for (HashMap<String, String> addvert : data) {
rows.add(new MyAddActivateRow((LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE), addvert));
Log.d("MyActivateAdapter", "update " + data.size());
}
super.notifyDataSetChanged();
}
