Android :: Positioning Listview At A Particular Location On Screen
Aug 19, 2010
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'm trying to figure out how to save the location my ListView is scrolled to. Currently I am saving the ArrayList of the ListView. When the user comes back to the screen I reload the ArrayList but can't figure out how to make it scroll to the last location.

i'm in final stage of writing my custom widget (quite similar to Home's sliding panel). it works quite well except one thing: i have some problems with positioning it in FrameLayout (see 3 rightPanel* Panels in main.xml in attached eclipse project).basically i don't like the idea i'm using there: setting layout_marginTop in panelHandle children.

I'm developing an android app and need to know how to change the positioning of a progress dialog. I need it to be positioned at the bottom of the screen instead of at the center like it is by default.

I have the following structure defined in an xml layout file.
<RelativeLayout android:id="@+id/mainLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content">
<FrameLayout android:id="@+id/frame" android:layout_centerInParent="true" android:layout_width="wrap_content" android:layout_height="wrap_content" ></FrameLayout>
<Button android:id="@+id/button" android:layout_below="@id/frame" android:layout_width="wrap_content" android:layout_height="wrap_content" />
</RelativeLayout>
The FrameLayout is positioned correctly in the center of its parent. But the Button isn't getting positioned under it. Instead it's displaying in the top left corner. Am I doing something incorrectly or is this a bug with RelativeLayout?

I have a binary file which contains keys and after every key there is an image associated with it. I want to jump off different keys but could not find any method which changes the index positioning in input stream. I have seen the mark() method but it does not jump on different places.
Does anybody have any idea how to do that?

Is there a replacement keyboard that has a way to position the cursor without sliding out the useless physical keyboard? I despise the keyboard and would never slide it out if there were another way to move the cursor around.
I wish I liked the Incredible, but I don't. I would pay retail for a Droid without the keyboard and with the cursor function of the Incredible.

I'm new to android development. Is it possible for a view (with a particular layout) to "appear" at the location where the user "touches"? If so, how? Like the idea of right-clicking on your computer - a menu pops down wherever you right-click and when you navigate away, it disappears.

I am using these three lines to add a compass on the MapView: mMyLocationOverlay = new MyLocationOverlay (this,mapView);mMyLocationOverlay. enableCompass(); mapView.getOverlays() .add(mMyLocation Overlay) ; However the default position of the compass showing on the screen is not too good for my apps, and I want to move it to somewhere else. Anyone knows how I can achieve that?

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.

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 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.

I'm developing a mapping app using Eclipse 3.5.I'm setting the minimum update period with the LocationManager's requestLocationUpdates method, via a configuration activity. When I set the property I see in Logcat that the system process sets the value OK.When I actually send a new location from the DDMS emulator control and the location changes on the map view, I see that the system process then sets the minimum time to zero.Below is a capture of the system's log messages. You can see that I'm setting the period to 32 seconds, then 16, then, after I've sent a simulated location change the system sets it to zero.The map responds to location changes to location changes instantly even if they are sent only a couple of seconds apart.

In my application I have to fetch the current location. First it correctly fetches the location. But we are moving from the current location to some other location. It shows the previous address. It is not updating the location. My code is: locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); locListener = new MyLocationListener();locManager.requestLocationUpdates(LocationManager .GPS_PROVIDER ,0,0,locListener); location = locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);if(location != null){latitude = location.getLatitude();longitude = location.getLongitude();} Please find the mistake and when i launch first time it is not working on second time itself it is working so check this thing also.

I have an application which uses the network as the location provider (rather than GPS eg.), however I can't seem to figure out how to send the emulator test coordinates. In DDMS I would usually send coordinates in the Emulator Control tab.Is there a place to simulate coordinates derived from the cell phone network provider?

I want to override the method enableMyLocation() in MyLocationOverlay class, in order to implement my own positioning algorithm to get latitude/longitude, and then plot them onto a MapView. I figured out how to do that, but now I'm stuck because I dont know what Canvas to pass when I call the method drawMyLocation().
Here is the MyLocationOverlay class
