Android :: Relative Layout In Java Code With Inflate And Custom View - Position Error

Jun 16, 2009

I have a custom view that I had to write for a large scrollable image, as the images are larger than the size of the screen. Before, I had tried to do it by putting the image into a ScrollView but that of course didn't work. The view itself is within a RelativeLayout within the activity and at the bottom of the screen I have two buttons that are used for navigation and at the top a TextView with a caption for the activity (the main header is already being used here for instruction). In my below code, I've checked the Hierachy Viewer to confirm all the elements are loaded and in the Activity I can see the TextView, however it overlays the ZN5ScrollView area and below the image I just have a blank area of the size defined rather than my buttons. For the bottom navigation, the Hierachy Viewer is saying the absolute_y of the bottom navigation is 480. I'm wondering if anyone can help with my layout code here to get this working correctly? Bottom navigation is 50px high, ZN5ScrollView is 365px above the navigation, and the TextView takes up the rest of the area at the top

Android :: Cannot Create New Map View To Draw To Off Screen Bitmap

Oct 29, 2010

I'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?

Android :: Position Views At Specific Location?

Jul 4, 2010

Is there a way to place widgets / views on the screen at any specific position required?

Something like a calendar with daily events that could overlap.
e.g. if every hour in a day is represented by 1 hour and there are 2 appointments that overlap partially (say 12:00 - 12:30 and 12:20 - 01:00) this would be drawn in the same row but the 12:20 one positioned slightly below the first.

Also there may be views (Image/TextView) that need to span 2 rows (i.e. 12:30 - 1:30).

I think a SurfaceView is one option (is this efficient?) but am not sure if there is some better layout that could be used.

We could use a TableLayout for the hour rows but not sure if there is a way to place overlapping widgets on this?

Android :: Draw ImageView At Specific GeoPoint On MapView

Oct 1, 2010

Trying to solve my current problem of drawing an image on an Android MapView and then animate it to represent a moving object, I decided to try to just draw a raw ImageView at a GeoPoint on the map and then try and animate it from there.

This is the code I put in my map activity (extends MapActivity)'s onCreate method:

CODE:..............

Again, I'm just trying to draw the static icon and animate it from there. I can already do this with an ItemizedOverlay, but as far as I can tell, I can't animate the elements of an AnimatedOverlay the way that I can animate a view. Thus, using ImageView.

But the icon doesn't show up.

Android :: Layout Should Stay At Specific Position After Content Change

Sep 14, 2010

I have a layout which contains a TextView.

The content of the TextView might change on runtime. (discussed on a different issue here: http://stackoverflow.com/questions/3683727/layout-with-dynamic-position )

I can position the layout by drag&drop. If the size of the layout doesn't change, the position stays, but as soon as the size of the layout changes (because more text inside the TextView) the position is reseted.
I use the layout(left, top, right, bottom) to position the layout.

Now I don't know where I should add my layout() call to make sure it stays at the right position...

Here is my class

CODE:............

View tmpView = this.findViewById(viewId);
Rect hitRect = new Rect();
tmpView.getLocalVisibleRect(hitRect);
the hitRect is always 0,0 - 0,0.

I need the x,y mainly to scroll to a particular child view. Any help is greatly appreciated.

HTC EVO 4G :: Screen Rotation - Delay When Switch From Horizontal Position To Vertical Position

Sep 29, 2010

On my htc i was looking through display, i see g sensor calibration and i perform this calibration and after i do so the screen seems to have a delay when switch from the horizontal position to the vertical position. its weird because when i switch to the phone horizontally it switch normally and responds fast. but when i switch back to vertically it takes almost 7 seconds to actually switch back, sometimes it switch within 2 or 3 secs but never as quick as switching horizontally.

If you're already updated, shut down and repower (soft reboot) should do the trick. I actually updated my phone and after it started to do this. I restarted the phone plenty of times i even took the battery out for 30 seconds. It only does it when im texting on the browser, basically everything but the camera. He camera screen rotation is perfect. I even rooted the phone but i havent figured out how to use the root to fix the problem. Should i do a firmware update? Because i just did the htc software update.

Android :: Animating View Position?

Feb 3, 2010

I'm trying to do something which seems simple. I want to have a map view, with a menu that slides up from the bottom of the screen where settings (for overlay) can be adjusted. However when I use a TranslateAnimation to affect the y position of the LinearLayout (which holds the menu), the buttons in the LinearLayout move, but there "hit area" stays in the same position as they were before the animation.

CODE:.........

I've also looked into tweening the view's marginTop value, but haven't even been able to determine how that would be done.

Android :: Draw View At Runtime?

Mar 29, 2010

I'm just getting started with developing for Android. I'm looking to port one of my iPhone applications, but I'm kind of at a loss for how to draw a view at runtime (a view not declared in the XML). Basically, I want to draw a simple rectangle, but then be able to manipulate its frame after being drawn. Sorry if this is a really, really simple question, but I can't seem to find some equivalent to the iPhone SDK here.

Android :: How To Draw Button On Top Of View?

Jan 8, 2010

I am creating a android app using LunarLander as a example.Now I need to create a few buttons which are drawn over the view.I do not want them as a seperate layout above or below the view but in the custom view.Is this possible or am I going to have to programmatically show the button images then detect the touch. The buttons I create using new never show on the app. I assume this is because I have overwritten the onDraw and the buttons are never drawn even though I call.

I currently have a view in my Android app and the view is playing a frame animation. I want to animate the view to increase its size to 150%.
