So I changed my DPI setting to 150 since in launcher pro I use 5 rows instead of 4 so it doesn't overlap etc. And wanted to ask if changing the DPI setting may affect the battery usage (recalculating screen) or CPU (making it slower) or the games will lag? etc.
Changed it back, I think was lagging and the text boxes were smaller not on the whole page. And the confirmations had green lines in the middle.
How I did it:
1. Root Explorer , mount R/W in system
2. Open in text editor.
3. Edit the build.prop line with ro.sf.lcd_density=150 and save the file
4. mount R/O and reboot
Still if someone knows something about the battery usage and cpu etc. So I know in future if I should play around with this one.
I'm using a Droid X, and I bought a spare battery so I can go all day wihtout a fill up so to speak. However I'm noticing that whenever I place a one of the other batteries in, it gives me the same reading as the last battery that was in it, no matter what. Any way to fix this?
View 6 Replies View RelatedI have a question about data usage while roaming. Multimedia messages are the same as data, thus I cannot send a picture message while roaming (I have my phone set to reject data if roaming). But sometimes I do not notice the roaming signal until after I hit send. If this happens, my EVO will continue to try to send the message and will alert me of the failure every couple of minutes.
Is there a way to stop this from happening? In other words, if I try to send a picture message, and I am roaming, is there a way to put the whole process on hold until I get a full signal again? It is very annoying to have it keep beeping at me. The only way I can stop it is to put the phone on Airplane mode. But then I can't do voice calls, or send and receive regular texts.
How exactly do I use my own pictures?
I downloaded an image from commons on my phone. I then hit settings->personalize->home wallpaper->Photos and then select the image when it appears. I get the confirmation popup "the picture has been set as your wallpaper" but when I hit the home key nothing has changed.
If I select any image from "photos" it does this, but if I select HTC or Live wallpapers it works fine.
I downloaded Astro because I'm suppose to be able to change the names of my pictures with it but when I open the program I can find all sorts of files, but I can't find a folder for my gallery or my library where the pictures are suppose to be. I think they should be there anyway.
Once I found a place to type a "name" & search but that did not find those file folders either. I thought I might search the "Name" of a photo I have on the phone but now I can't even find where to type in the name/date & time again.
I have some contacts on my home screen for direct calling. When I add a contact picture for them in google contacts online and synchronize, it only appears in the list of my contacts but won't change on the homescreen, even when restarting the phone...

I copied everything from my old SD card to the new one. Also, the new SD card have a different name from the old one. Old is labeled as 'Removable Disk' while new one is 'Kingston'. Also, album thumbs folder becomes empty (before it contains files from old album thumbs folder).

Based on everyone's feedback I might have to return the Moment for a third time.
View 1 Replies View Relatedis it possible to use onKeyDown() for an ImageButton instead of onClick() to capture the user's click on this imagebutton?
View 3 Replies View RelatedHow can I have an imagebutton stay in the 'pressed' state when it is clicked? Basically I just want the background to be the depressed background, but I can't figure out how to set it. At the moment, I've just copied the selected button background into my res folder, but when I set it as the background, it becomes blurry (since the original image is bigger than the button itself).
Normal Background:
What I'm getting:
Also I don't believe I can actually use this method considering the many different UI layouts. The button should stay pressed as per the UI the user is using.
Wanted to leave a ImageButton is disabled (not clickable), but have used android: enabled = "false" but does not work
Does anyone know how to disable an ImageButton?
I'm using the following code, which I expect would scale the associated image to fit within the given dimensions of the button:
CODE:.....
The image is 64X64 and I was expecting to see 32X32 on the screen. However, the button draws with the original 64X64 size. I can re- sample the image down and create a new file but I'm curious why this approach didn't work.
I have problem with width of ImageButtons, it isn't the same size. I have experimented with all attributes for two hours and nothing. I create buttons at runtime and put inside row (also created at runtime).

I have a button with two states(selected and unselected). the image of button is different for the states. Which one should I use? How do i set images and states?

Here is my code:

I'm having a problem when setting the visibility of two image buttons one on top of the other. The idea is to implement a play/pause control. The problem is that the only part where setting the visibility actually works is in the click listeners of the buttons. If I try to change it somewhere else nothing happens.

I'm trying to create a transparent (no button background) ImageButton that has a custom selector. I have the selector working against the button but I now want the selector drawables to cross-fade into each other.
I saw the TransitionDrawable object that can be represented in XML. Is there a way to connect this into my selector?
Below is the XML layout code to create the image button on the screen in the lower left corner of the screen. It currently goes from one image to the next abruptly ignoring the transition XML.
CODE:.....................
I have 1 imageButton and i want to hide that button after 5sec in oncreate method.

View 5 Replies View RelatedIf I was using an ImageButton with a selector for its background, is there a state I can change which will make it change its appearance? Right now I can get it to change images when pressed, but there seems to be no "highlighted" or "selected" or similar state which lets me toggle it's appearance at will.
Here's my XML, it only changes appearance when pressed.
CODE:........................
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?
View 2 Replies View RelatedI want to setImageResource for an ImageButton programatically, based on a variable.
For eg: if size=5, I want to setImageResource to R.drawable.five if size=6, I want to setImageResource to R.drawable.six
Unfortunately, I have too many of these, so an if-else or switch gets tiring.
Is there a way to achieve something like: R.drawable.size?

In a standard button the color changes to orange when pressed, I'd like to change a custom image button with a different image.
