Android :: ImageButton Flash Orange When Background Image Is Set?

Mar 26, 2009

I've set the background image of a custom ImageButton I am building, as well as setClickable(true) and setFocusable(true). The button is able to receive focus when I navigate with DPad/arrow keys in the emulator, however, it does not flash orange when it has the focus. It does not appear to change at all when it has the focus, in fact. When I remove the background image, however, the ImageButtons hold orange when they have focus.

What do I need to do to be enable an ImageButton with a custom background image to flash orange when it has focus?

Android :: Size Of Background Images To Support All Android Screens

Jun 25, 2010

I'm writing an application and I want one of my activities to have a background. I've read the android docs about supporting multiple resolutions etc. but my designer is asking me what size the wallpapers should be and I do not want a lot of images for low, normal, high dpi in all the screen sizes.

What would be the most space efficient way to get a nice screen filling graphic background on all those screens? Android is great and all, but I do not want to end up with a huge application since I need all sizes of images for everything.

Android :: Way To Manipulate The Droid Activity Stack?

Jun 23, 2010

1 - User opens app for the first time ever from android home screen User is presented with "first time" screen (backed by first time activity, lets call it A) User hits back button user is returned to android home screen 2 - User opens app for second time User is presented with the main list screen of the application (backed by a list activity, let's call it B) User hits back button User is returned to android home screen I'm already aware of numerous ways to detect whether it's the first time opening the app or not. The problem is in having the back button return to the home screen rather than a routing activity that decides which screen to forward to.

Android :: Getting Home Screen Positions

Oct 19, 2010

My question today relates to the android home screen and where it stores icon / widget positions. Specifically, I am interested in accessing the positions and sizes of any icons that are currently being displayed. I have, so far, been unable to find a method of retrieving the positions of other applications but i figure it must be possible in some way due to the presence of third-party home screen applications. Ideally, I am hoping to query the positions of whatever is on the screen at the moment from a live wallpaper and adjust my rendering accordingly.

Android :: Specifying Relative Positions In Layout?

Sep 30, 2009

I need to implement a screen containing a list of blocks one below the other. Each block will contain mutiple superimpose elements (Images, text) for which the relative position needs to be specified with respect to the top left corner of the block.

For creating the list of blocks i have used listview. For each block i tried to use relative layout.This works ok when the phone is in landscape mode and absolute position is specified relative to left edge of the phone. But when the phone is put in the portrait mode the layout gets distorted.

1) What layout can be used for this scenario?

2) Can relative positions be specified in terms of percentage of screen width/height instead of pixels?

Android :: Change Object Positions In Layout?

Jun 7, 2010

I'm currently working on a very simple aplication, and I intended to make it change the visual aspect depending on the screen size. The application just has 6 buttons like this:

I'm using the AbsoluteLayout, and changing the x and y of the buttons with the methods offsetLeftAndRight and offsetTopAndBottom. I'm not changing the layout of the buttons in the xml file, so the all start in the same place.

However, if I use this methods inside the onClickMethod they sometimes appear where I want them, sometimes don't (can't figure out why), but if i use them in the onCreate method, nothing happens.

Android :: Advanced Gradients - Thumb Positions?

Oct 16, 2010

I am trying to create a gradient drawable to depict a ratio of something. As a general example, lets say you were looking at a listview containing a fleet of cars. The background could be a fuel gauge - I don't want a smooth, wide transition. I want a very tight transition, and I want to be able to set where that transition takes place.

Here's what I'm staring with, but I'm not getting very far.

Android :: Icon Image Rotate Positions In Contacts?

Jan 10, 2010

I thought it may have been my eyes, when I thought I saw an upside-down Android icon for a contact the other day, on my Android 1.5 device - Samsung Moment. I was playing with contacts just now, and I saw the upside down icon again. Then I was curious, went to see other contacts, and I noticed the Android icon facing right, then facing left in other instances. There is no rhyme or reason as to when the Android icon will change positions, but it is there.

Android :: Draw Cupola Circles At Random Positions

Jun 15, 2010

I am trying to draw a cupola circles at random positions in an Android application. I draw them on a bitmap and then draw that bitmap on the canvas. This is the function where a draw the circles:

private void drawRandomCircles(int numOfCircles) {
Canvas c = new Canvas(b);
Paint cPaint = new Paint;
for(int i = 0; i < numOfCircles; i++) {
int x = Math.Random % 100;
int y = Math.Random % 100;
c.drawCircle(x, y, 20, cPaint)

The Bitmap b is global. And after calling this function I just draw the bitmap in the onDraw method. Now the problem is that I only get one circle drawn on the screen, no matter the size of numOfCircles.
