Android :: Need Screen Which Contains A Few Labels Under Them Listview
Dec 4, 2009
I am starting with listactivity. I was able to create a simple list view using ListActivity and Arrayadapters. The problem before me now is i need a screen which contains a few labels and fields and under them a listview. how to go about it ? moreover whats the difference between layout and activity ? how well should i use them ? Until now I thought one application one activity, but after looking Apisamples i found myself wrong. A few correct links will help. is "busy programmers' guide to android dev" a good book ? Can I get a softcopy from somebody?

I have a customized Cursor based adapter for my ListView. Each Cursor has a few columns of data, sorted by the priority column. I know you can create a disabled list item to act as a sort of header, like in the Market app (the little green labels). What I would like to do is display a header for each group of items with a different priority. They are already sorted by priority. Example data:
title, priority
note1, high
note3, high
note2, low
note4, low
Example of what I want in ListView:
= High Priority =
-note1
-note3
= Low Priority =
-note2
-note4

This may have been covered but if so, I can't find it. Is there a way to set home screen shortcuts without labels? I think that would really clean things up when you have several.

I'm trying to add a label to each of the points on a map that I've created. Setting the "title" and "snippet" values of the OverlayItem don't seem to automatically cause these labels to appear however. I would've thought this would be a pretty simple and common requirement. Am I missing something? Can someone tell me if there's a function that does this?

I've found that apps which come into my inbox bring up a notification, awesome. However, I have Gmail filters setup to sort out my numerous emails into various labels, but keep them unread. Is there a way to get notifications for new emails which go into those labels?

I am building a MapView and I want my custom overlay items to display the name of the location they are marking when the user taps them, like the Android Maps app. I setup the onTap listener and the floating TextView to hold the location name. I still need to set it up so that it redraws the label when the user moves the map, etc. Anyway, I am wondering if I am reinventing the wheel here. Is there a built-in method I am unaware of? I would think that most implementations of MapView have labels. For reference, my implementation so far: in map xml:
<LinearLayout android:id="@+id/mapBubbleWrap" android:layout_width="wrap_content"
andoid:layout_height="wrap_content" android:layout_alignParentTop="true">
<TextView android:id="@+id/mapBubble" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:visibility="gone"
android:background="#ffffff" android:textColor="#ff0000"/>
</LinearLayout>
in my extended ItemizedOverlay:
public boolean onTap(int index) { this.setFocus( mOverlays.get(index) ); return true; }
in my Activity onFocus:
public void onFocusChanged( ItemizedOverlay overlay, OverlayItem item ) {
if( item != null) { mapBubble.setText(item.getTitle());
Point newPoint = mapView.getProjection().toPixels(item.getPoint(), null);
mapBubbleWrap.setPadding(newPoint.x, newPoint.y-10, 0, 0);
mapBubble.setVisibility(View.VISIBLE); } }

I am new to Android. I plan to check for new mails on Google Mail (GMail) that are archived to their labels. Are there any examples that'll show how to do this (Gmail API, etc.?)? I searched a lot but found no helpful information about this, hope someone can help. What do I need?
Is there a way to check (with push) whether there are new mails in a label. I think the standard Gmail Android app could not do this!?

I want to show this array as a listview in a new screen when a button is clicked.
ArrayList<String> favorite = new ArrayList<String>();
This ListView is a small part of my class. i cant seem to figure out how to implement it with my code (i can figure out how to create a listview in a separate application, and set the onitemclicklistner just for that listview) i want to display that listview when.
case R.id.ShowFavButton:

A simple ListView with, say, 6 rows (Views). Now, I want it to fit exactly a single screen. Any straightforward way to do this? Or should I go with a custom view?

I'm trying to write an app for my Samsung Vibrant (running android 2.1).I used the example "Form Stuff" app available as tutorial on the android developers website. I basically added a background picture to the application. the background picture has some text on it towards the top. I want to display a list of elements (to be selectable by teh user) but I want this list to start from a certain position on the screen (say for example - start from the middle of the screen). tried reading the listview under dev resource and searched the forums but I could not find a way to do this.Could anyone please help me out? or if this is not possible, then suggest me something else which i can place at a certain position on the screen.

I just installed Folder Organizer Lite on my Desire in order to be able to change the icons on my home screen. It worked like a charm, but now I have a question. I am able to edit the name of the icons, for example I have changed Advanced Task Killer to ATK, but I would like to have the option to not have any text at all. When I go to alter the text as usual and just delete the text, nothing changes. So does anyone out there know how to completely remove text from underneath icons?

I designed the user interface of my app on the emulator and then I installed it on the Nexus one. For some reason the text boxes, labels buttons etc. have shrink in size. It looks as if the view has been zoomed out on the phone. If I arrange it correctly on the phone the objects don't fit on the emulator. Has anyone faced this? Is there some setting to have consistency between the look of the emulator and Nexus One.

Comparing a MapView as used in an app through Google Maps API against the Google Maps app, I found that the granularity of all elements, most visibly, street labels, in Google Maps is bigger than the street labels in MapView. This is on a Nexus One, presumably other devices show a similar behavior. I did not find any hint in the documentation how to dial this for a MapView.

I have TabHost with custom ListView implemented. My ListView disappears after returning from SMS screen when I try to switch tab (refresh list content).
I have context menu option to send SMS to contact from the list, I start SMS activity there and Im able to return to my app. If I don't type anything in SMS screen, just return immediately everything is fine. List will work. If I type something in SMS and press back key, toast will be displayed: "Your message is saved in Drafts". And now if try to switch tabs, list content disappears.
Debugging revealed that list items are present, and that list adapter constructor is called. However, listAdapters GetView function is never called. And list results are not displayed.
I found similar problem in this post: http://groups.google.com/group/android-developers/browse_thread/threa...
Im working on sdk 1.5 and device.
Here is my list adapter function, pretty standard:
CODE:..................
my ListView widget has no special properties, just width and height to fit parent.

I have two textviews, a listview (this is a listactivity, by the way) and a datepicker. All is supposed to be displayed in this order, vertically.
The problem is that the ListView is pushing the datepicker below the screen, to the depths of the unseen world. I want the datepicker to have its own space, fixed at the bottom, while the listview grows as needed, but still allowing datepicker to have its own space.
+/- like this:
~~~~~~~~~~~~~~~ screen top
TextView 1
TextView 2
|
|
|
| ListView [*]
|
|
|
DatePicker (stays here no matter how much List grows or shrinks
~~~~~~~~~~~~~~~ screen bottom
[*] -> This listview will scroll a lot, but won't hide datepicker!
I know it's very lazy to ask for ready code, but could you guys share a light? This is driving me crazy. I've tried millions of combinations I believe.

I'm trying to add a listview on the bottom of my opening activity that has two text items. Anyone know how to do this? I see stuff on how to do a listview with two columns, and how to do a listview at the bottom of an activity, but I can't find any that does both.

I have a listview that when scrolled and the items go off of the screen they are not redrawn when I scroll back to them (the text and checkbox). In fact, items that are off the bottom of the screen in the listview never get drawn when scrolling to them. This only happens in Froyo. Any other version it works just fine. I have checked and the data is there as expected in the adapter when the getItem method is called, it is just not visible. The listview item is there (it's occupying the same amount of screen space per item), I just cannot see the text or checkbox once scrolled off screen and back on again. Code...

I'm having trouble setting up an Android Layout.
What I would like is a scrollable ListView followed by a small bar of text (TextView) that doesn't scroll and always stays at the bottom of the screen.
it would look like this:
ListViewItem1
ListViewItem2
ListViewItem3
Bar of Text Here (always displayed irrespective of scroll state of the ListView)
I've tried a bunch of different variations on this, but none shows the static text
CODE:................

I created a list view in an activity and the list shows some fields.When we click a list item a custom dialog should pop up and the user can enter some new value to this field.The custom dialog contains one edit text and two buttons ok and cancel.It is working fine.But when my list is more that means if it exceeds screen size it is showing scroll.But when we select bottom items which we can select using scroll the dialog is appearing in normal fashion.But after entering new value if i am trying to save the application is getting crashed.

Hello everyone. Is there a feature or a check box that I am missing that allows you to turn off the little text labels beneath the application icons on the home screen? I'm kind of doubtful, but a search did not return an answer. It would certainly clean up the home screen. Plus a lot of labels are "cut off" due to length and that is just annoying.

Eventually found out how to do this as there was a customize feature on the HTC Magic. The solution is to do it through Google Contacts and then synchronize the contacts back to the phone. Simple - pity no one at HTC Support seemed to know.

We have used a Google domain and provided mail (gmail) for some time. Have quite a number of labels in use to file things. Only a few labels I need synced to my EVO. Inbox is obvious and is at the top of the list so easy to find etc. Problem is that the 4 or 5 others that I use regularly are all down the list in alpha order. Is there anyway to reorder the list of labels to bring the sync'd ones to the top or to filter so non-synced labels do not show in the list? Or perhaps shortcuts I could build on my home page to go directly to other than inbox?

I have TabActivity that uses 2 other ListActivities for the tabs. Both underlying ListViews are set to CHOICE_MODE_MULTIPLE. When I run the following sequence of events, I get a strange result: 1) Setup one activity (tab) and its ListView using a CursorAdapter, including checking some items on the list 2) Reorient the screen (open the keyboard) 3) Setup the second activity (tab) and its ListView using a CursorAdapter, including checking some items on the list 4) Switch back to the first tab
At this point, I can see in Eclipse that although (of course) each ListView is a distinct object, the internal variable used to store the checked state of items, called mCheckStates, is the SAME OBJECT REFERENCE in each of the ListViews.
Clearly this is an issue, since the two views should not share the checked state of items between them.
If I skip step #2, this does not occur
Here is a bit more detail:
After Step 1: ListView1 is object reference @1, ListView1.mCheckStates is object reference @2
After Step 2: ListView1 is object reference @3, ListView1.mCheckStates is object reference @4 (the reorientation recreates the views)
After Step 3: ListView2 is object reference @5, ListView1.mCheckStates is object reference @2 <-- note the reuse of this reference from step #1, not sure how/why
After Step 4: ListView1 is object reference @3 (unchanged), ListView1.mCheckStates is object reference @2 (changed) <-- same as ListView2.mCheckStates
