I'm working with json. I parsed the JSON and I can show my JSON (images and text) on ListView. Now I want to show JSON's first item's title in my widget.
I successfully created the widget but I have a problem with the JSON's first item's title.
This is a my code:
public class AppWidget extends AppWidgetProvider {
public static String CLOCK_WIDGET_UPDATE = "CLOCK_WIDGET_UPDATE";
RemoteViews views;
int appWidgetId;
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if (CLOCK_WIDGET_UPDATE.equals(intent.getAction())) {
Toast.makeText(context, "onReceiver()", Toast.LENGTH_LONG).show();
}
}
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
final int N = appWidgetIds.length;
for (int i = 0; i < N; i++) {
appWidgetId = appWidgetIds[i];
Intent intent = new Intent(context, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
intent, 0);
views = new RemoteViews(context.getPackageName(),
R.layout.widget_demo);
String aa = (MainActivity.itemList.get(0)
.get(MainActivity.KEY_title)).toString();
views.setOnClickPendingIntent(R.id.widgetPic, pendingIntent);
views.setOnClickPendingIntent(R.id.widgetTitle, pendingIntent);
views.setOnClickPendingIntent(R.id.widgetDesc, pendingIntent);
views.setTextViewText(R.id.widgetDesc, aa);
views.setImageViewBitmap(
R.id.widgetPic,
((BitmapDrawable) context.getResources().getDrawable(
R.drawable.background)).getBitmap());
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
public void updateAppWidget(Context context,
AppWidgetManager appWidgetManager, int appWidgetId) {
RemoteViews updateViews = new RemoteViews(context.getPackageName(),
R.layout.widget_demo);

My problem is: When I click the widget I get

That is too much code to look at. Please narrow your issue down and show the exact point the issue is occurring at.
Use your debugger to step through your code. 1st, identify the exact line at which the issue is occurring. Next, use your debugger to inspect the variables at that point. The error is an index out of bounds, so you're accessing a point in a list that is bigger than the size of the list.

Ok..The problem is in your case that the Async task runs on separate thread from UI thread So when you call BackgroundWorker3 in getData method then UI thread doesn't wait for Async task response(separte thread) and StoreList have null value. So you see StoreList doesn't have any value and in listView nothing will show.
Write this code in onPostExecute method not in onCreate..
#Override
protected void onPostExecute(ArrayList<HashMap<String, String>> arrayList) {
StoreList = arrayList;
mListView = (ListView)v.findViewById(R.id.mList);
mAdapter = new ListViewAdapter(getActivity());
for(int i=0; i<StoreList.size(); i++){
HashMap<String, String> each = StoreList.get(i);
String name = each.get("name");
String tel = each.get("tel");
String lat = each.get("latitude");
String lon = each.get("longitude");
mDestination.setLatitude(Double.valueOf(lat).doubleValue());
mDestination.setLongitude(Double.valueOf(lon).doubleValue());
float distance = mCurrentLocation.distanceTo(mDestination);
mAdapter.addItem(getResources().getDrawable(R.drawable.sin), name, tel,Float.toString(distance));
}
mListView.setAdapter(mAdapter);
}

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.
My layout is very complex. I have to make full page scrollable so what i did is - i have a gridView adapter for my gridview items and one custom adapter which has four tabs and then i set my gridview in that custom adapter. Then this whole view is set on my main activity which has a listview so its now scrolling with full page but issue is with memory.
I have 4 tab click events on custom adapter from which i am sending those click events through put extra to main activity where i have four web service and a condition that if 1st tab is selected then 1st web service call will occur and new adapter will set on main activity.
problem: when i click on 1st tab my memory size is 130 MB and on click of 2nd tab it raises to double so and same thing is happen when i click on 3rd tab. I am using lazy loading for loading my images which also maintains my caching, i have tried clear(), notifyDataSetChanged() but doesn't make any change. My memory is increasing on each click of tabs.

The description you showed is indicating a possible memory leak. Check my answer for this question. My guess is that you should use the Application context instead of the Activity context in your code. Use the video in the answer mentioned to know how to identify the leak.
I had four tabs in my view and the tab output depend on other tab input in same view. So when I click on one tab, it generates an array list and show item in list view but when second time I click on the same tab it gives array index out of bound exception. I think it is because of previous downloaded content was in the view so how to remove/delete previous loaded content when I clicked first time on tab. I know it can be done onresume() and onpause() method but what code should be in onpause() for removing previous loaded content. For refreshing it with new content. ontabclick().
Thanks!
