This is what I want to achieve. When ever a user taps at any point on the screen, I would like to show an image at that point for say 2 seconds. Is it possible ?

I'm just wondering to know if a can with a background service have co-ordinates of a touch screen event in all activities.
Such like that code...
I am a novice in android programming and wanted to work on the GPS related apps. I tried using DDMS in eclipse but it doesn't send the co- ordinates (or my app doesn't pick it up). I tried typing 'geo' with the co-ordinates but it gives a message as permission denied. Could some one please tell me how do I go about sending GPS co-ordinates and also use the emulator.

I'm new to Android, I've followed the hello world tutorial through and have a basic idea of what's going on. I'm particularly interested in the touch screen of my T-Mobile Pulse so just to get me started I want to be able to write the co-ordinates of a tocuh event on the screen, so say the user touched the co-ordinate 5,2 - a textview on the screen would display that.
At present I have a simple program that just loads an xml file which contains the textview I intend to write the co-ordinates in.
Thank you in advance, I did Google for help and searched stackoverflow but everything I found either went way over my head or wasn't suitable for this.
In my application I use an image . I made some portion of the image transparent. Now How can I find the co-ordinates of the transparent portion of the image so that I am able to find the actual area of the non-transparent area.. I want some methodical way to find.

View 1 Replies View RelatedI am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............

View 1 Replies View RelatedI have a custom view i am writing for my drawing app but the first time i set the drawing into it i need to get the dimension for the view (using getMeasuredWidth() & getMeasuredHeight()). But until the view display these return 0. I have tried calling: requestLayout() invalidate() numDraw.measure(MeasureSpec.EXACTLY, MeasureSpec.EXACTLY); but nothing seems to force the values to update.I guess the question i am asking is : does anyone have any tips on how to get view to update its measurements off screen?

View 3 Replies View RelatedIs it possible to create a view that is bigger than the screen? I need a view that has a bigger width then the screen of the device. I use this view in a rotation animation. During the rotation the parts that were not on the screen before animating the view will become visible.
Is there a way to achieve this effect with the android framework?
I tried to set my parent layout much bigger then the screen and it is working. This will make somethings a little bit uncomfortable but it could work. The next problem now is that my layout still starts at the left side of the screen. I can't think of a method to make the layout to expand itself to the left and the right of the screen.

At run time i am attaching two image views for frame layout.I wanted to capture screen coordinates of frame layout.But Couldnt do it.if i say
(FrameLayout) f=(FrameLayout)findViewById(R.id.frame14); int[] loc = new int[2]; f.getLocationOnScreen(loc); System.out.println(loc[0]); System.out.println(loc[1]);

If I try to get f.getLeft() and f.getRight() they return as 0 coordinates.

I am trying to play a video via streaming in my android application. Video playing functionality works good but whenever changes the orientation of the phone...a white screen comes over the video view and audio keeps playing. And after turning back to original orientation, video starts playing normally..(with proper video and audio.) what should i do?
View 1 Replies View RelatedI'm trying to create a MapView in a service (live wallpaper), but have it hidden so that I can render it to a Bitmap, and then map it to a texture to render in opengl. I have a Canvas and a Bitmap, and I intended to call myMap.draw(myCanvas) in order to get it into the correct bitmap so that I could then bind it as a texture.
When I Initialize I do the following:
myMap = new MapView(ctx, APPSTATICS.MAP_API_KEY);
I get an error:
java.lang.RuntimeException: stub at com.google.android.maps.MapView.<init> (Unknown Source)
Why I can't create a new mapview which I can use to draw to a offscreen bitmap?
I have ads that display on the top and bottom of the screen, and I'd like them both to slide off the screen smoothly, instead of just disappear. Is there some way to do this? They are both WebViews, if that makes any difference.

View 3 Replies View RelatedI am writing a home screen widget. Is it possible to add a View, e.g. ImageView, to a home screen widget through RemoteViews? I want to generate the views for the home screen widget dynamically.

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.

View 1 Replies View RelatedI previously asked a question that I still have not been able to solve:
http://stackoverflow.com/questions/3126347/android-relativelayout-how-to-alignparentbottom-when-wrapped-in-a-scrollview
What I am trying to do is align a view to the bottom of the screen, using either a RelativeLayout or LinearLayout, and then wrap that layout in a scrollview to permit scrolling when necessary (for changes to landscape orientation or on small screen devices).
To date, what I find is that anything aligned to parent bottom works great as long at the bottom is visible...but if the bottom is below the scroll, the view that is aligned parent bottom jumps up to the top.
This seems like a very common design for ads that appear on the bottom, so I would think that this is possible. Is it?
I'm trying make a View that divide the screen in three sections. The first section should be 200dip high, the third section should be 50 dip high and the middle section should take the remaining place in the middle. Is there any way to implement it? I tried some ways but either it doesn't work or the app crashed.

View 1 Replies View RelatedI read somewhere in the Android documentation that (paraphrasing here): 'if you do make your own View take up the whole screen, it is then possible/even-advisable, to insert and manage the 'status-bar' within your View'. How do you do that? - i.e. insert the status-bar within ones own 'full- screen' View?
View 3 Replies View RelatedI 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.
