Android :: Can View Appear At Location Where User Touches Screen

Nov 19, 2010

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.

Android :: Changing Drawing With OpenGl When User Touches Screen

Nov 10, 2010

I'm developing an Android application. I'm very new on it. I have the following classes:
class CustomGLSurfaceView extends GLSurfaceView
class CustomRenderer implements GLSurfaceView.Renderer
CustomGLSurfaceView uses CustomRenderer to render a cube on onDrawFrame method.

I've added an onTouchEvent(MotionEvent event) on CustomGLSurfaceView to manage touch events:
class CustomGLSurfaceView extends GLSurfaceView {
// For touch inputs - previous touch (x, y)
private float previousX; private float previousY;
private CustomRenderer myRenderer; public CustomGLSurfaceView(Context context) {
super(context); myRenderer = new CustomRenderer(); setRenderer(myRenderer);
} @Override public boolean onTouchEvent(MotionEvent event) {
float currentX = event.getX(); float currentY = event.getY();
switch (event.getAction()) { case MotionEvent.ACTION_MOVE:
myRenderer.handleMovement(currentY, currentY, previousX, previousY);
} // Save current x, y
previousX = currentX; previousY = currentY;
return true; // Event handled } }

May I have to modify onDrawFrame to draw something new or to rotate the cube? I thing I must do it on handleMovement.

Android :: Intercepting Screen Touches During Game

Jun 15, 2010

What's the best way of intercepting screen touches and coords during a game loop? At this point, I don't have a View from my main.xml file, so the normal OnTouchEvent doesn't apply, as far as I can tell. What's the usual procedure for this?

HTC Incredible :: Phantom Screen Touches A Little

Apr 29, 2010

Mine just started registering phantom screen touches a little while ago.It seems to think there is either and up-swipe or some kind of touch near the top of the screen randomly. For example, an email or list will constantly be scrolling up or if I leave it on a screen with Power Panel on it, one of the icons will randomly highlight orange. The page with the google search widget will have the search field highlight orange on it's own too. When entering text, the cursor will randomly jump back to the beginning.

I've never had a smartphone YET, but my daughter has a Droid and says she hates that when talking on it, her cheek touches the screen and changes stuff while talking. She's new to the phone itself, so is she doing something wrong or is this just a con of smartphones? Or is this a Droid thing and not an EVO thing?

HTC Desire HD :: Screen Detecting Ghost Touches

Nov 24, 2010

After much waiting for my desire HD I was (and am) really pleased with it. However in the last couple of days my screen appears to be detecting a second touch which pretty much prevents me playing games and is a real hindrance when typing. I could accept this if it were the gel protector or my hand running over the side of the screen, but it seems to be around the "rtuio" bit of the keyboard when holding the phone in portrait mode (i.e. the centre). I do have a screen protector on there but there are no air bubbles or anything visible underneath it. So yeah, has this been raised before? I couldn't find anything. Do I need to recalibrate the screen somehow?

Android :: Developing Application For Multiple Screen Support?

Mar 6, 2010

I want to develop UI of the application which looks similar on all screen sizes. I have gone through the Android developer article regarding this. I am using supports-screen tag but then also the screen is displayed not displayed properly in the larger screens. The screen is displayed properly in HVGA and not in WVGA.

I have developed the application using Android 1.6 and set the minimum SDK version as 4. The application is running properly on HVGA avd but not on WVGA avd. Can I know the reason for it? Is there any solution for this? I want that the user interface of the application should look uniform in all the handsets.

Android :: Switch Image Of An ImageButton When User Releases Button?

Feb 7, 2010

I'm trying to make it so that as long as a user is touching the button, it shows one image, and when the user releases the button, it goes back to a default image.

I'm trying to use a selector to make this happen:


I've tried a few things with the selector, but it always produces the same behavior: the button starts out with the default image, then I press it and it changes to the "record_on" image and it never goes back to the default image when I let go.

Is there a way to get this kind of behavior with an ImageButton, or should I be using something different?

HTC EVO 4G : AT&T User Going To Switch - Pre-order At BB

May 13, 2010

Few questions about the EVO: If I pre-order at BB, can they hold the phone for a week or so? I'm going to be out-of-town for about a week after the launch. I don't want to wait until I get back, since they will likely be sold out.

1 Year contract possible for a higher up-front charge? I was looking at the HTC Incredible, and I like that I can pay $70 more for a 1 yr contract. If Sprint's network leaves something to be desired, I'm concerned about a 2 yr contract. I'd also like to get device upgrades each year...a 2 yr old smartphone these days is not fun to have.

General :: Switch Between User Accounts On Nexus 7?

Nov 29, 2013

In January, I acquired a Nexus 7, and in July, I met my boyfriend. Yesterday, I suggested that we put a user account for him on the tablet, so that he could have quicker access to his own email, writing and so forth. This we accordingly did, and he has been having great fun installing apps for chess and ukelele playing, as well as working on his writing. However, this means that the lock screen is back. The lock screen irritates the b*ggery out of me, and I disabled it as fast as I could when I originally bought the tablet. The way you are meant to switch accounts, however, involves bringing up the lock screen every time, and it also means the lock screen appears whenever the tablet is wakened from sleep. I tried disabling the lock screen, but then we couldn't switch user accounts.

So far, the best solution I've found is to have a desktop widget for the No Lock app, so that I can have the lock screen disabled during the day, when I'm the only one using the tablet, and then put it back on when my boyfriend is around and we're both using the tablet. This will probably be fairly manageable, and I realise that I'm whingeing about a few seconds of screen-swiping here and there, but what would be really lovely would be if we could just have a widget we could press on our home screens that allowed us to switch user accounts, without all this faffing around with lock screens. I've been hunting through Google Play apps, and so far all I've encountered is one which sounds thoroughly dodgy and may not even do what I want.

Android :: ViewFlipper & Multiple Images?

Oct 14, 2010

I need to include multiple images in my Android app. It's like an image viewer/slideshow. Currently I switch between pictures from /drawable-mdpi dir simply with ImageView and adapter, using gestures to left/right. Works but nothing impresive :/

Basically I could use something like Android (2.1) gallery with some image show animation.

1st question: what's the best way to include many (50-100) fullscreen images in App?

2nd: is it possible to use ViewFlipper animations directly to images? or do i have to somehow populate Views?

Android : Way To Maintain Multiple Images?

Aug 22, 2010

During my game loop I am constantly loading images using BitmapFactory.decodeResource(getResources(), R.drawable.objectx); Most of the time I'm calling images that have already been decoded earlier. Am I slowing down execution by decoding the resource every time? Is it better to store every image into a Map (or Dictionary) at the beginning of the program? If so, how do you get the resource IDs for all images in the drawable folder?

Android :: AppWidget - User Can Select Multiple Sizes

Aug 9, 2010

I'm looking at creating an AppWidget and want to have the user select which size they want before adding it. Thus, the user can choose 1x1, 2x2, etc. The Calendar widget in Android 2.2 (and possibly earlier, but not in 1.6) does this. How is this done?

Here's the code I've got so far:

import android.os.Bundle;

Android :: Rotate Particular Image Among Multiple Images Drawn To Canvas In Droid

I want to rotate only the second bitmap around its center of axis instead of rotating the entire canvas(which includes first bitmap also).

Android :: Display Multiple Images From Remote Source In Gallery - Zoomable - Pannable

Jun 1, 2010

I want do display some images that I load from a remote source in a gallery. The gallery should let the user do the following things:

-zoom the image (preferably also by pinch-zoom) -pan the image -switch between the different images

Of course most built-in gallery applications can do all of that. So my first idea was to use an ACTION_VIEW intent in order to delegate the task to some gallery application. This however won't work for me since you can only pass the URI of the image you want to display but not the actual bitmap data itself. I can't just pass the URL of the remote image because I need to manage the loading and caching of the data myself. A way around this would be to write the data to a local file and then pass the URI of that file (and deleting the file again afterward). Besides this being less than elegant it won't even do the trick because with an intent like this you can only pass one image at a time.

The built-in Facebook application on the Nexus One actually does exactly what I have in mind for displaying photo albums. It looks like a custom gallery activity they built into their application. Does anyone know whether there are templates available for something like this somewhere that one could reuse? Building something like this from scratch by myself seems too time consuming.
