I want to set a specific image when my button is not clickable. This button image is already selected according focused and pressed state thanks to this xml:
But I do not know how to define a new image for the button when it is not clickable.

Can anybody please guide me how to write the code for opening the new image after clicking the imagebutton in android. I have tried something like this:
package com.example.imageButton;
import android.app.Activity; import android.os.Bundle;
import android.view.View; import android.widget.ImageButton;
public class imageButton extends Activity {
private static ImageButton seqIBtn;//these are the three imageButton private static ImageButton vidIBtn;private static ImageButton infoIBtn; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); seqIBtn = (ImageButton) findViewById(R.id.btnSequence); vidIBtn = (ImageButton) findViewById(R.id.btnVideo); infoIBtn = (ImageButton) findViewById(R.id.btnInfo);}
I have a BroadcastReceiver set up in my Android application that receives SMS receive events. This works fine, but I want to be able to toggle SMS receiving on and off by toggling the BroadcastReceiver on and off. Because if I have a simple boolean inside the onReceive method, even if the SMS receiving is off, my application will start.

View 2 Replies View RelatedI've written a test service to understand how android implements a service. I believe I understand the difference between Context.startService and Context.bindService. If I am not mistaken, Context.startService will tell android to keep this service running, even after the Activity that started it has ended.
While testing the service, I have come across something interesting.
My problem is that the service appears to sleep or pause for a few hours, run a short time, and then sleep for a few more hours, then run a short time, etc when the phone has become inactive. In other words, when I am doing things on the phone the service is doing what is is supposed to. But after I have finished doing things on the phone and the screen goes blank the service appears to sleep or pause. I don't know if I have implemented the service wrong or if this is how Android services work.
The test service I have written simply sets a postDelayed handler to increment++ a variable in the Runnable every minute, and then write the value of that variable and a timestamp to a file (log.txt) on the sd card. This how I know that the service appears to sleep. Because there are gaps in the timestamp that correspond to when the phone was inactive. If the service were truly active the whole time, there should be a line item in the log.txt file every minute.
From the log.txt file below you can see that over an eleven hour period there are only 36 line items with time stamps ranging from 10:27 PM through 9:23 AM. If the service was running and active the whole time there should be over 600 lines in the text file. The phone was on AC power the whole time so Android should not have tried to stop services due to power issues. The phone was not used or touched from about midnight to 9 the next morning, so there should not have been a low resource clean up.
I have spent several days looking for an answer and everything I can find seems to validate that when a service is started and not bound, it will stay running (http://code.google.com/android/reference/android/ app/Service.html). However, it appears it does not. Unless I have completely missed the ball on this.
I have included the service.java and activity.java as well as the log file.
Here is a sample log.txt

I'd like to know how to make a button out of a PNG and display it on my canvas (using drawBitmap?). When I click on this button, it will take me to a new activity. All this will be in the onClickListener. So, how do I take a PNG, make a button with it, and draw it on my canvas? I looked at ImageButton, but I'm unsure how it works or how to draw it on the canvas.

View 1 Replies View Relatedeach child is horz linear layout w/ 3 children: image view, linear layout container and then an image button
if the image button is GONE - then i get click notifications when someone clicks on the list entry. if the image button is VISIBLE (even if i don't intercept onclick) - i don't get the list click event notification.
Is there a way to create Buttons that contain both an Image and Text (image on top text below or image left and text right)? And how can this be done within a xml layout file? For example, the application 'Pkt Auctions eBay' (see Android Market) has these type of buttons.So far I have tried and googled all over and found nothing on the matter. Help is much appreciated. Thanks in advance.

View 5 Replies View RelatedA '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.
I'm trying to have an image (as the background) on a button and add dynamically, depending on what's happening during run-time, some text above/over the image. If I use ImageButton I don't even have the possibility to add text. If I use Button I can add text but only define an image with android: drawableBottom and similar XML attributes as defined here.
However these attributes only combine text & image in x- and y-dimensions, meaning I can draw an image around my text, but not below/under my text (with the z-axis defined as coming out of the display). One idea would be to either extend Button or ImageButton and override the draw()-method. But with my current level of knowledge I don't really know how to do this (2D rendering). Maybe someone with more experience knows a solution or at least some pointers to start?
