In my ListView, I choose an Item to "Add Favorite" and I have to do some stuff work, I fill data again to refresh the List, then I implement OnScrollListener use setSelection(firstVisibleItem) to set List display right on Item was added. Are there any better way to do that. I mean like mCursor.requery() or something like that in android APIs ? Or any suggest way?

I have two cursor, one of them from contact content provider, other one from database. id fields are sycnhorinzed.i want to show them in same column with two row in list. i m think that i have to use simpleCursorAdapter, because arrayadapter and other adapters can not show two cursor in a list.

So my list is not refresing/updating altough all cursors all results are updating.

What is an efficient to refresh my listView? I don't want the listView to re-trigger a query since there is no data change.
I have listview with items that include both text and images. If I scroll the listview fast enough all items images are messed up: wrong images are displayed for wrong items. The same problem exists with expandable listview. I tried to implement holder class to cache imageview and image itself using setTag, getTag but nothing helps. The faster I scroll the more items are messed up. Text almost always displayed correctly.
View 5 Replies View RelatedI have a CursorAdapter attached to a ListView, the ListView contains checkboxes for every row. When I check/uncheck a checkbox in a row it will update it to a 0 or 1 in the database (This is working fine) I also have another checkbox in the same Activity that when pressed will disable all the checkboxes in the ListView [ setEnabled(false) ].
The problem is that when I press this checkbox the ListView checkboxes return to their initial state when I started the activity. It does not matter the number of checkboxes I changed during the activity.
However, if I press the back button and then re-enter the activity all modifications are saved because the Cursor is refreshed. I am calling notifyDataSetChanged() at the end of the the methods that disables all the checkboxes.
I also tried this for every checkbox in the ListView but it did not work (was unable to check a checkbox) Any ideas?
What is the best way to display a database queries results on the screen using ListActivity? I need the db queries to run in the background and I also need to be able to make different queries and refresh the screen according to the query result. I am using the ListActivity class with a SimpleCursorAdapter in order to display the db queries result on the screen. At the moment, I am doing the db queries at the background using AsyncTask, when getting the results I want the list to be updated immediately, but I can't find a good way to do it. It worked only when I used the changeCursor(cursor) function to set the adapter to a new cursor with the new results. But I don't think this is a good solution since it seems to stuck the UI for a while. I also found some posts about notifyDataSetChanged() but I am not sure if/how/when I should be using it with a SimpleCursorAdapter to make the view refresh.
View 2 Replies View RelatedWhen I add drawable resources to my project they do not show up in the list of drawables in the Reference Chooser. I checked the R file and there are references for the files.
I have tried refreshing the project, cleaning the project, and fixing project properties and nothing seems to help. Sometimes a couple will randomly show up in there, but not all of them.
The only consistent way I can get them to show up is to restart Eclipse.
Further findings:
After some trials, I found an other inconvenient work around to he issue. Turns out when importing multiple files into the project at once, Eclipse will only add the last one imported into the reference chooser. So when I imported my images one at a time, they all show up properly!
Like I said, inconvenient considering the amount of images I have left to import, but maybe with this new information it may help nail down where the issue may be and a possible fix.

Currently I am working on IM, and I am facing problem during implementations. I am implementing this messenger using XMPP client and using smack API for implementing all features like contacts list, online offline status, and chat also. Prblem which I am facing:
Its my list view where I am showing contacts list
public class ContactsList extends ListActivity implements OnClickListener{
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ContactsManager manager = new ContactsManager(this); setListAdapter(manager);
} public class ContactsManager extends BaseAdapter{
private LayoutInflater mInflater; private Bitmap mainListIcons[];
private static ContactsInfo contactsInfo; public ContactsManager(Context context) {
mInflater = LayoutInflater.from(context); mainListIcons= new Bitmap[3];
mainListIcons[0] = BitmapFactory.decodeResource (context.getResources(), R.drawable.online);
mainListIcons[1] = BitmapFactory.decodeResource (context.getResources(), R.drawable.offline);
} @Override public int getCount() { return Global.contacts.size();//
contacts is vector where I am saving my contacts
} public Object getItem(int position) { return position;
} public long getItemId(int position) { return position;
} public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder; if (convertView == null) {
convertView = mInflater.inflate (R.layout.main_settings_lists_icon_text, null);
holder = new ViewHolder(); holder.mainListDisplayText = (TextView) convertView.findViewById(R.id.main_settings_lists_text);
holder.mainListDisplayIcon = (ImageView) convertView.findViewById(R.id.main_settings_lists_icon);
convertView.setTag(holder);}else{ holder = (ViewHolder) convertView.getTag();
} contactsInfo = (ContactsInfo)Global.contacts.elementAt (position);
String username = contactsInfo.getUsername(); String status = contactsInfo.getUserstatus();
if(status.equalsIgnoreCase("unavailable")) { older.mainListDisplayIcon.setImageBitmap(mainListIcons[1]);
}else{ holder.mainListDisplayIcon.setImageBitmap(mainListIcons[0]);
} holder.mainListDisplayText.setText(username); return convertView;
} static class ViewHolder { TextView mainListDisplayText;
ImageView mainListDisplayIcon;}
public class ContactsHandler implements RosterListener {
@Override public void entriesAdded(Collection<String> c) {
for(String s:c) { Log.i("ADDED Contacts",s);
} } @Override public void presenceChanged(Presence p) {
Log.i("PRESENCE",p.getFrom()); Log.i("IS Available",""+p.isAvailable());
Log.i("UserStatus",""+p.getStatus()); if(p.getFrom().contains("@") && p.isAvailable())
{ ChatManager chatmanager = Connection.getVopConnection getXMPPConnection().getChatManager();
Chat newChat = chatmanager.createChat("gulfam@imran-mehmood", new ChatHandler());
} } }
I would like to after I have updated by listAdapter I want to make sure that the list is scrolled all the way to the bottom so that it displays the last element entered in the list How can I do this ?I tried this but no luck.
View 1 Replies View RelatedI have had this problem for a while but never tried to fix it but now discovered it is not only on my GNex but also my Tab 2....
Basically i have email via virginmedia.com, which i believe is all set up correctly with POP enabled etc and my phone/Tab 2 email client set up to never delete from server. Problem is the email comes to the devices fine and i can reply, send new email etc, but if i refresh the list to check for any new email, what was already in my inbox just disappears from my device, not into the bin, just gone for good!
I have Android 4.2.1 on the GNex ans 4.1 on the Tab 2. Remember this is the general email client and I am on Virgin Media, this is not the Gmail email app, I do not use that. would really like to be able to get my email on the move without knowing I will lose it all straight away!
I am using Google Sync to sync my Outlook on my desktop to my Google calendar on my phone. I am using Jorte to view my calendar on my phone.Whenever I make a change on my desktop in Outlook (or even in Google Calendar online), the only way I seem to be able to get it on Jorte fairly quickly is to go to default calendar on Droid, choose "refresh" option", then go back to Jorte calendar and make sure it is there.
1) Does Jorte have its own "refresh" option?
2) Why do I even need to do this?
After implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no idea how to tell the map activity to refresh on its own and display the new coords. the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view?

View 2 Replies View RelatedThe way I want it is, per row there will be a text and is followed by a right arrow button, so that the user can click on that button to edit the content of that row. If the user is using the keypad, by using the left and right buttons on the keypad, he should be able to select the textview or the Button in that particular row. I have seen this in a couple of apps. The way I see that working on those apps appear as if they are maintaining two lists in parallel.
The reason i felt it this way is, if I am on row 1 of the list and if I press the right key on the phone keypad, then the right arrow button will get highlighted and now if I use the down key or if I keep pressing the down key, then the focus will scroll through that arrow button only as if that is an another parallel list constructed. I don't know if that is a good way to do it. I tried many for getting this to work, but couldn't succeed.
I have a listview from an SQLDatabase using custom CursorAdaptor. I would like to go back to the activity that I used to create the items when I click on them in the listview. So that I can edit the entries. But nothing happen when I implement the OnItemClick method and the getItemId() on the CursorAdapter even though am not sure I am correct there. Here is my Code:
public void onItemClick(AdapterView<?> adapview, View view, int position, long rowId) {
Cursor c = adapter.retrieveRow(rowId); // retrieve row from Database
Intent edit = new Intent(this,NewItem.class);
edit.putExtra(DBAdapter.KEY_ID, rowId);
edit.putExtra(DBAdapter.Title, c.getString(c.getColumnIndex(DBAdapter.Title)));
edit.putExtra(DBAdapter.DATE, c.getString(c.getColumnIndex(DBAdapter.DATE)));
startActivity(edit); } public long getItemId(int id){ return id; }

Countries is just an array with a list of countries, some dummy values. Now, how do I make the list items of the BTListView class go in the ListView (with @+id/listview) of the main class? Now my list works, but it isn't clickable anymore. This is the code:

I am trying to overwrite the default backgroud color of List item which is holding the focus in the ListView. As you can see, in Android Setting Menu, when you scroll through the ListView, the focused ListItem has a red backgroud to highlight its focus. Does any way to change the default behavior by highlighting it with other color or just a bottom red line under this Item.

The list view loads itself with the rounded corners, but then, the items of the list hide the round corners.
