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:
CODE:...............
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?

A 'Button' view comes up with text, while the 'ImageButton' widget comes up with an image but no text, is there a way to relatively easily (e.g. method calls, say), either:
1. Add text to ImageButton (like those buttons that appear in menu item/via the physical menu button)?
2. Add an icon/image to a Button?
without resorting to constructing a new button class? I.e. I could put text within the image, but then I can't use Localization properly/effectively.

When using the "selector" to specify different images for buttons for different states, such as pressed, focused etc, do I have to write an xml file for each button? I have about 15-20 buttons in my app, so was wondering if there is a way to write just one xml and refer to parts of it?

I want to set image dynamically on the ImageButton in android. However, i have more than 200 images. what would be the good solution for that?
The best idea is that i can use the name of image to call different images. i.e. imagebutton.setImage("/res/abc.png");
however, it seems to me that it is not trivial to do so..

I'm porting an application from iPhone to Android. The iPhone app has artwork for some dozen or more buttons in their normal and pressed state. That translated over just fine to Android. However, we of course currently don't have any images for the "focused" state.
Besides the work involved in creating all these focused button images, we're not sure exactly what color to set the focus too. Selection color varies from phone to phone, etc. We'd have to come up with some neutral "white glow" of some sort I suppose. Then the idea struck -- could we programmatically render a focus images for the buttons based on the current selection color? Have folks been doing anything like this in the Android dev community? Can you point me to some examples. A net search didn't turn up anything too useful, though perhaps I searched on the wrong keywords.

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?

I want to create an Android ImageButton in the xml file with a background image, and a smaller icon on top of that, right in the center. For some reason, it's not obvious how to do it, and documentation is no help.code...
However, no matter what I try (putting "wrap _ content" instead of absolute numbers on layout _ height and layout _ width, the icon remains in the top left corner of the button. If, however, I have no background image (i.e. a system default white button), the icon does go into the center. The button also goes into the top left corner when I use a color instead of an image for the background.
Why does this happen, and how would I actually get the behavior I want-- that is, a background image with the icon in the center?

I have a widget on my home screen with several ImageButtons which have default background images. Through the configuration activity, I can change the image on any of the ImageButtons. The problem is that when the screen is rotated, the image on the ImageButton disapears and it changes back to the default image.
I don't know why this happens or how to fix it

I'm programming my first Android application and I've stumbled over a little problem.
I've created my own adapter ("extends BaseAdapter") for my ListView and in my "public View getView(...)" I have the following code:
My problem: How do I set the color back to "Color.BLACK" after the user releases the touchscreen?
I'm looking for something that is similar to Javascripts "onMouseUp" or "onKeyUp" methods. An OnClickReleaseListener() perhaps?
Can you point me in the right direction?

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.

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.

Let's say I have a few buttons in a LinearLayout, 2 of them are:
mycards_button = ((Button)this.findViewById(R.id.Button_MyCards));
exit_button = ((Button)this.findViewById(R.id.Button_Exit));
I register setOnClickListener() on both of them:
mycards_button.setOnClickListener(this);
exit_button.setOnClickListener(this);
How do I make a SWITCH to differentiate between the two buttons within the Onclick ?

I have an app out that involves keeping track of information over time. Part of the app is a reset button. In order to avoid accidental resets, I made that button respond only to long-clicks.However, that approach confused about 20% of my new users, who thought that the reset button must not be working.Is there a more intuitive (and standard) way to protect a button from accidental presses? (If not, I can add some sort of custom message to the button I have )

I have a BroadcastReceiver that receives SCREEN_ON. If the screen came on because the user pressed a button, I want to do something. However, if the screen was turned on by an app (e.g., alarm clock going off or SMS popup), then I don't want to do anything. Anyone know how I can differentiate between the two cases?
