The problem is getView method does not get called even when I do setAdapter on listView. Please see may code below. I dont get any error message. It just does not display reviewer data. Would you please suggest what I am doing incorrect.
MovieReviewerFragmemt class I have below code:
#Override
protected void onPostExecute (ArrayList movieDetailsArray){
getMovieArrayList(movieDetailsArray);
ListView listView = (ListView) rootView.findViewById(R.id.movie_detail_reviewerlist);
MovieAddlDetail detail = (MovieAddlDetail) movieDetailsArray.get(0);
MovieReviewers[] list = detail.getReviewerArrayList();
Log.v(LOG_TAG, "MovieReviewerFragment - CustomReviewerAdapter - calling adapter");
movieDetailAdapter = new CustomReviewerAdapter(getActivity(), list);
movieDetailAdapter.notifyDataSetChanged();
listView.setAdapter(movieDetailAdapter);
}
CustomerReviewAdapter:
public class CustomReviewerAdapter extends ArrayAdapter {
private Context context;
private LayoutInflater inflater;
private final String LOG_TAG1 = CustomReviewerAdapter.class.getSimpleName();
private MovieReviewers[] reviewers;
public CustomReviewerAdapter(Context context, MovieReviewers[] reviewers) {
super(context, R.layout.fragment_detail, reviewers);
Log.v(LOG_TAG1, "CustomReviewerAdapter - constructor");
this.context = context;
this.reviewers = reviewers;
inflater = LayoutInflater.from(context);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Log.v(LOG_TAG1, "CustomReviewerAdapter - getView");
if (convertView == null) {
inflater = LayoutInflater.from(context);
convertView = inflater.inflate(R.layout.fragment_detail_reviewer, parent, false);
Log.v(LOG_TAG1, "CustomReviewerAdapter - getView - convertview was null");
}
TextView textView1 = (TextView) convertView.findViewById(R.id.movie_detail_reviewerlist_author);
TextView textView2 = (TextView) convertView.findViewById(R.id.movie_detail_reviewerlist_content);
textView1.setText(reviewers[position].getAuthor());
textView2.setText(reviewers[position].getContent());
Log.v(LOG_TAG1, "CustomReviewerAdapter - getView - data set");
return convertView;
}
}

Below is activity from which fragment is being initiated. The first fragment is working fine and is being displayed. However the second fragment is where I dont get anything displayed. Is below correct way to initiate two fragments?
Detail Activity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);
Bundle extras = getIntent().getExtras();
intentData = extras.getStringArray("moviedetails");
MovieDetailFragment movieDetailFragment = new MovieDetailFragment();
movieDetailFragment.setMovieDetails(intentData);
MovieReviewerFragment movieReviewerFragment = new MovieReviewerFragment();
movieReviewerFragment.setMovieDetails(intentData);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container_1, movieDetailFragment)
.add(R.id.container_2, movieReviewerFragment)
.commit();
}
}
You must call the LayoutInflater like this:
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
You have to switch the lines
movieDetailAdapter.notifyDataSetChanged();
listView.setAdapter(movieDetailAdapter);
To
listView.setAdapter(movieDetailAdapter);
movieDetailAdapter.notifyDataSetChanged();
First you set the adapter, then you send the notification. If you do this the reverse way, there is no ListView which may display the updated data.
You can automate these notifications with
movieDetailAdapter.setNotifyOnChange(true)

I implemented a custom ArrayAdapter which causes the problem that any click on the TextView element of the ListItem is not recognized by the ListView; However clicking on the ImageView element of the ListItem leads to the desired effect. I just couldn't figure out how this behavior is caused even tough i followed the tutorials.
Everything works just fine when i use the standard ArrayAdapater.
I am going to include the involved classes since i don't know which of them is relevant to solve this issue.
CustomArrayAdapter:
public class ClassCustomArrayAdapter extends ArrayAdapter {
private ArrayList<ArrayList<String>> contactsArray;
private Context context;
public ClassCustomArrayAdapter(Context context, int textViewResourceId, ArrayList<ArrayList<String>> contactsArray) {
super(context, textViewResourceId, contactsArray);
this.contactsArray = contactsArray;
this.context = context;
}
private class ViewHolder{
ImageView imageView;
TextView textView;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if(convertView == null) {
convertView = layoutInflater.inflate(R.layout.fragment_custom_listview_item, null);
viewHolder = new ViewHolder();
viewHolder.textView = (TextView) convertView.findViewById(R.id.tv);
viewHolder.imageView = (ImageView) convertView.findViewById(R.id.iv);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.textView.setText(String.format("%s %s", contactsArray.get(position).get(2), contactsArray.get(position).get(1)));
viewHolder.imageView.setImageResource(R.drawable.ic_baseline_person_24);
return convertView;
}
}
FragmentListContacts:
public class FragmentListContacts extends Fragment {
private ArrayList<ArrayList<String>> contacts_arraylist;
private ArrayList<ArrayList<String>> contacts_array_listview;
private ArrayAdapter<String> contact_ids;
private ArrayAdapter<ArrayList<String>> contacts_arrayadapter;
private ListView contacts_listview;
private FloatingActionButton add_contact_fab;
private Database db;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_list_contacts, container, false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
contacts_listview = getActivity().findViewById(R.id.contacts_listview);
add_contact_fab = getActivity().findViewById(R.id.add_contact_fab);
initAddContactFAB();
db = new Database(getContext());
//db.insertNewContact("A", "B", "123", "321");
//db.insertNewContact("C", "D", "456", "654");
contacts_arraylist = new ArrayList<>();
contacts_arraylist.addAll(db.getContacts());
//contacts_arrayadapter = new ArrayAdapter<ArrayList<String>>(getContext(), android.R.layout.simple_list_item_1, android.R.id.text1, contacts_arraylist);
ClassCustomArrayAdapter classCustomArrayAdapter = new ClassCustomArrayAdapter(getContext(), R.layout.fragment_custom_listview_item, contacts_arraylist);
//contacts_listview.setAdapter(contacts_arrayadapter);
contacts_listview.setAdapter(classCustomArrayAdapter);
contacts_listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(getContext(), ActivityListNotesByContact.class);
startActivity(intent);
}
});
registerForContextMenu(contacts_listview);
}
...
}

Thanks in advance!
the ListView setOnItemClickListener intercepts the clicks of the root view of the list item, and as you enable the TextView as clickable, then it has its own click listener that won't be intercepted by the ListView setOnItemClickListener .
Solution:
You need to make both TextView and ImageView as not clickable or focus-able
android:clickable="false"
android:focusable="false"
You can use below list item layout..
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:layout_marginRight="15dp"
android:layout_marginBottom="5dp"
android:gravity="center_vertical"
android:clickable="false"
android:focusable="false"/>
<TextView
android:id="#+id/tv"
android:layout_width="match_parent"
android:layout_height="50dp"
android:clickable="false"
android:focusable="false"
android:layout_marginLeft="5dp"
android:background="#FFFFFF"
android:gravity="center_vertical"
android:textColor="#000000" />

I currently have a listview that contains a button and EditText view. How do I properly implement an OnClickListener in my list adapter so when each button is clicked, the associated EditText within the view is hidden via the setVisibility method.
Based on my current implementation of the OnClickListener in my list adapter, when I click a button to hide the corresponding EditText within the view it hides the very last EditText within the viewport and does not hide the corresponding EditText that it's in the same view as the button. Below is my listview xml file (inspection_single_row.xml), my list adapter (InspectionAdapter.java) and main activity (MainActivity).

inspection_adapter = new InspectionAdapter(getApplicationContext(), R.layout.inspection_single_row, inspectionList);
lv.setAdapter(inspection_adapter);
}
}
Edit:
In this part
Log.i("ConfirmAdapter","EditText # position : " + holder.deficiency_notes.getTag())
you are still referencing the holder variable that is created last. As i said before: In getView, for every view, you create a new ProgressHolder assigning it to holder variable. So holder is overwritten everytime getView is called. That's why, Log.i gives your last item.
Try the following:
Put the new ProgressHolder inside if clause.
if(v == null)
{
holder = new ProgressHolder();
This way it only creates a new instance, when the view is null.
Instead of setting the tag for the button to position you can set it to holder like this
holder.my_button.setTag(holder);
you don't need to set tag for EditText.
Then in the onClick you get the corresponding instance of ProgressHolder via getTag() and change the visibilty like this:
holder.my_button.setTag(holder);
holder.my_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
ProgressHolder clickedHolder = (ProgressHolder)view.getTag();
clickedHolder.deficiency_notes.setVisibility(View.GONE);
}
});
I'm trying to make a custom listview. I'm not getting error and data are correctly added to my ArrayList but I see nothing on screen. Is there a problem with a layout or the adapter ?
Here is my list row layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/nomtv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"/>
<TextView
android:id="#+id/desctv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="#+id/debuttv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/nomtv"
android:layout_toEndOf="#+id/nomtv"/>
<TextView
android:id="#+id/fintv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/desctv"
android:layout_toEndOf="#+id/desctv"/>
</RelativeLayout>
Here is my custom adapter:
public class ListTacheAdapter extends ArrayAdapter<String> {
ArrayList<Tache> taches;
ListView listView = null;
final Context context;
View rowView = null;
TextView nom = null, desc = null, debut = null, fin = null;
public ListTacheAdapter(Context context, ArrayList<Tache> taches) {
super(context, R.layout.row_tache);
// TODO Auto-generated constructor stub
this.context = context;
this.taches = taches;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = inflater.inflate(R.layout.row_tache, parent, true);
nom = (TextView) rowView.findViewById(R.id.nomtv);
desc = (TextView) rowView.findViewById(R.id.desctv);
debut = (TextView) rowView.findViewById(R.id.debuttv);
fin = (TextView) rowView.findViewById(R.id.fintv);
nom.setText(taches.get(position).getNom());
desc.setText(taches.get(position).getDescription());
debut.setText(taches.get(position).getDebut());
fin.setText(taches.get(position).getFin());
return rowView;
}
}
My activity layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.example.testapp.ShowActivity" >
<ListView
android:id="#+id/list"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#D46A6A"
android:dividerHeight="1dp"/>
</RelativeLayout>
And my activity class:
public class ShowActivity extends Activity {
ArrayList<Tache> taches;
ListView listView;
TacheDAO td = new TacheDAO(this);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show);
td.open();
taches = td.getAllTache();
td.close();
ListTacheAdapter lta = new ListTacheAdapter(this, taches);
listView = (ListView) findViewById(R.id.list);
listView.setAdapter(lta);
}
}
I'm also a beginner, so i tell what i'd try:
I believe that the problem is in the calling to super() on the onCreate method of the adapter. Try passing super(context, -1) insted of super(context, R.layout.row_tache).
Let me know.
I have one activity that contains text view, buttons, spinner and list view
my main XML file contains :

lv1=(ListView) findViewById(R.id.listView1);
ArrayAdapter<String> ard1=new ArrayAdapter<>(this, android.R.layout.simple_dropdown_item_1line,s1);
lv1.setAdapter(ard1);
but i can't change font color or font type in list view or spinner. how can i do it?
You need to create a CustomListAdapter.
private class CustomListAdapter extends ArrayAdapter {
private Context mContext;
private int id;
private List <String>items ;
public CustomListAdapter(Context context, int textViewResourceId , List<String> list )
{
super(context, textViewResourceId, list);
mContext = context;
id = textViewResourceId;
items = list ;
}
#Override
public View getView(int position, View v, ViewGroup parent)
{
View mView = v ;
if(mView == null){
LayoutInflater vi = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mView = vi.inflate(id, null);
}
TextView text = (TextView) mView.findViewById(R.id.textView);
if(items.get(position) != null )
{
text.setTextColor(Color.WHITE);
text.setText(items.get(position));
text.setBackgroundColor(Color.RED);
int color = Color.argb( 200, 255, 64, 64 );
text.setBackgroundColor( color );
}
return mView;
}
}
The list item looks like this (custom_list.xml):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/textView"
android:textSize="20px" android:paddingTop="10dip" android:paddingBottom="10dip"/>
</LinearLayout>
Use the TextView api's to decorate your text to your liking
and you will be using it like this
listAdapter = new CustomListAdapter(YourActivity.this , R.layout.custom_list , mList);
mListView.setAdapter(listAdapter);
If you really want to use androids simple list layout, we see that they declare their textview's identifier as such:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
style="?android:attr/dropDownItemStyle"
android:textAppearance="?android:attr/textAppearanceLargeInverse"
android:singleLine="true"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:ellipsize="marquee" />
So just make your custom adapter, inflate their layout & find that text view's id. Something like the following:
public final class CustomAdapter extends ArrayAdapter<String> {
private Context context;
ViewHolder holder;
private ArrayList<String> messages;
public CustomAdapter(Context context, ArrayList<String> data) {
this.context = context;
this.messages = data;
Log.d("ChatAdapter", "called constructor");
}
public int getCount() {
return messages.size();
}
public View getView(int position, View convertView, ViewGroup viewGroup) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.simple_dropdown_item_1line, null);
holder = new ViewHolder();
holder.message = (TextView) convertView
.findViewById(R.id.text1);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.message.setText(data.get(position));
holder.message.setTextColor(Color.BLUE);
// don't do this, remember the face variable once just showing explicitly for u
Typeface face=Typeface.createFromAsset(getAssets(), "fonts/HandmadeTypewriter.ttf");
holder.message.setTypeface(face);
return convertView;
}
public static class ViewHolder {
public TextView message;
}
}
Edit: The following is how you would use the custom array adapter in your activity.
// I'm not sure if your sp or lv1 wants the adapter, but
// whatever you require your list view's data to be just
// set the custom adapter to it
CustomAdapter<String> myAdapter = new ArrayAdapter<String>(this, s1);
lv1=(ListView) findViewById(R.id.listView1)
lv1.setAdapter(myAdapter);
You can do like this, add a ListView item in xml，at res/layout/list_item1.xml:

then,
ArrayAdapter<String> ard=new ArrayAdapter<>(this, android.R.layout.simple_dropdown_item_1line,s1);
sp.setAdapter(ard);
lv1=(ListView) findViewById(R.id.listView1);
ArrayAdapter<String> ard1=new ArrayAdapter<>(this, android.R.layout.simple_dropdown_item_1line,s1);// **change R.layout.list_item1**
lv1.setAdapter(ard1);
You have to put the .ttf file of font(which you want to add ) in asstes/fonts/ folder and write code in onCreate method like below. i have puted Chalkduster.ttf in my asstes/fonts/ folder
TextView txttest = (TextView) findViewById(R.id.txttest);
Typeface custom_font = Typeface.createFromAsset(getAssets(),
"fonts/Chalkduster.ttf");
txttest.setTypeface(custom_font);
You can handle clicks of selected item by write code just like below
ListView lvNews = (ListView) findViewById(R.id.lvNews);
lvNews.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int position, long arg3) {
// Write your code here
//int newsId = newsArray.get(position).getId();
//Intent i = new Intent(NewsListActivity.this,
// NewsDetailActivity.class);
//i.putExtra(Constants.NEWS_ID, newsId);
//i.putExtra("isFromNotification", false);
//startActivity(i);
}
});
Hoping someone can help. I'm having an issue it seems inflating my view. My goal is to display a list of items in a custom layout using a custom array adapter. I re-worked some of my original code using another SO post, but where my simple adapter worked fine, the new list doesn't display. Please see below:
This is my Fragment class.
HomeFeedFragment.java
public class HomeFeedFragment extends ListFragment {
private ListView listView;
private ArrayList<MainEvent> items;
private MainEventListViewAdapter adapter;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_homefeed,
container, false);
listView = (ListView) rootView.findViewById(android.R.id.list);
return rootView;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
//GetEvents is just a test method to return a list of pre-filled event objects
items = GlobalList.GetEvents();
adapter = new MainEventListViewAdapter(getActivity(), android.R.id.list, items);
listView.setAdapter(adapter);
}
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// do something with the data
}
}
My custom row layout xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="5dip" >
<!-- ListRow Left sied Thumbnail image -->
<LinearLayout
android:id="#+id/thumbnail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginRight="5dip"
android:padding="3dip" >
<ImageView
android:id="#+id/list_image"
android:layout_width="50dip"
android:layout_height="50dip" />
</LinearLayout>
<!-- Heading Text -->
<TextView
android:id="#+id/eventheader"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/thumbnail"
android:layout_toRightOf="#+id/thumbnail"
android:textColor="#040404"
android:textSize="15sp"
android:textStyle="bold"
android:typeface="sans" />
<!-- Event Description -->
<TextView
android:id="#+id/eventdescription"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/thumbnail"
android:layout_below="#id/eventheader"
android:layout_marginTop="1dip"
android:layout_toRightOf="#+id/thumbnail"
android:textColor="#343434"
android:textSize="10sp"
tools:ignore="SmallSp" />
<!-- Posted Time -->
<TextView
android:id="#+id/eventpostedtime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignTop="#id/eventheader"
android:layout_marginRight="5dip"
android:gravity="right"
android:textColor="#10bcc9"
android:textSize="10sp"
android:textStyle="bold"
tools:ignore="SmallSp" />
</RelativeLayout>
The actual fragment layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
And my custom ArrayAdapter:
public class MainEventListViewAdapter extends ArrayAdapter<MainEvent> {
private Context context;
private List<MainEvent> eventList;
public MainEventListViewAdapter(Context context, int textViewResourceId, List<MainEvent> eventList){
super(context, textViewResourceId, eventList);
this.context = context;
//this.eventList = eventList;
}
/*private view holder class*/
private class ViewHolder {
ImageView imageView;
TextView txtEventHeader;
TextView txtEventDescription;
TextView txtEventPostedTime;
}
public int getCount(){
if(eventList!=null){
return eventList.size();
}
return 0;
}
public MainEvent getItem(int position){
if(eventList!=null){
return eventList.get(position);
}
return null;
}
public long getItemId(int position){
if(eventList!=null){
return eventList.get(position).hashCode();
}
return 0;
}
public View getView(int position, View convertView, ViewGroup parent){
ViewHolder holder = null;
MainEvent rowItem = getItem(position);
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if(convertView==null){
convertView = inflater.inflate(R.layout.fragment_homefeed_rowlayout, parent, false);
holder = new ViewHolder();
holder.txtEventHeader = (TextView) convertView.findViewById(R.id.eventheader);
holder.txtEventDescription = (TextView) convertView.findViewById(R.id.eventdescription);
holder.txtEventPostedTime = (TextView) convertView.findViewById(R.id.eventpostedtime);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
holder.txtEventHeader.setText(rowItem.getHeadline());
holder.txtEventDescription.setText(rowItem.getDescription());
holder.txtEventPostedTime.setText(rowItem.getPostedTime());
/*TextView text = (TextView) v.findViewById(R.id.label);
text.setText(m.getHeadline());
ImageView imageView = (ImageView) v.findViewById(R.id.icon);
imageView.setTag(m.getImageURL());
//DownloadImageTask dt = new DownloadImageTask();
dt.execute(imageView);
return v;*/
return convertView;
}
public List<MainEvent> getEventList(){
return eventList;
}
public void setEventList(List<MainEvent> eventList){
this.eventList = eventList;
}
}
^ I initially had an Async Task in this class to retrieve images for each item, but I've removed all of that for now.
I don't get any actual errors in LogCat, no crashes or anything, the View just isn't inflating. Any help is appreciated.
Well this is embarrassing. I found out the issue. Apparently, I forgot to uncomment the line in the adapter constructor that initializes the event list:
//this.eventList = eventList;
I'd commented it out temporarily to fix another bug. Working fine now, but thanks for your suggestion.
