Android :: How To Get Pressed State Of Preference
Sep 10, 2009There is know problem in all the Android phones. Go to Bluetooth Settings->Turn ON bluetooth->Click on bluetooth discovery->Then timer will start in summary->Long press on Bluetooth device discovery-> observe Bluetooth ON/OFF title start to toggle with Bluetooth Discovery toggle. I analyzed the issue. Blueooth ON/OFF is CheckBoxPreference. Bluetooth Discovery is also CheckBoxPreference which has dependency on Bluetooth ON/OFF. When we click on Bluetooth discovery then On thread will run at every second to update summary in Bluetooth Discovery preference. When we change the Bluetooth discovery to OFF then thread will be removed/ killed. When i press the Bluetooth discovery for long time when its already in ON State then still the thread will be updating the summary (remaining time from 120 to 00) till i press it. When i leave the Thread will stop. As it has dependency on Bluetooth ON/OFF, its making to the title invisible. But it should not happen. Solution: When i touch the Device Discovery i should kill the update summary thread then i guess, that problem will be solved. But in prefence i dont have any listener to know the pressed state. I hope somebody can give me solution.

Android :: Save State Of Droid Application When Back Button Is Pressed?
Sep 20, 2010I have noticed while working in the emulator that whenever i get out of my app via any method other than pressing the back button, my toggle button (if pressed) will have its state saved and return to that state when i return to the app. im guessing its because its value gets saved in a bundle and reloaded when i return. when i leave the app via the back button, this does not happen and the toggle is always off when i return. is there any way to get the value of the toggle back if the user leaves via the back button, without having to save the value in a db table? alternatively, if my apps notification is in the status bar, i can be confident that the toggle should always be selected, so if there is no way to save the state, is there a way to find out if my apps notification is currently being displayed? then it would be easy to just set the toggle each time via a quick check of the status bar.
View 1 Replies View RelatedAndroid :: Modify Default Button State Without Affecting Pressed And Selected States?
Oct 4, 2010I am trying to remove an ImageButton's background in only the default state. I'd like the pressed and selected states to behave as usual so that they look correct on different devices, which use different colors for the pressed and selected states.
Is there any way to set an ImageButton's background default state's drawable without affecting the pressed and selected states?
I've tried to do this with a selector, but it does not appear to allow you to use the default drawables for some states - you have to set all the states yourself. Since there's no API to retrieve the device's default pressed/selected drawables, I don't know what to set the pressed/selected states to.
I also tried getting the StateListDrawable object for the button that the system creates when you are not using a selector and then modify it change the default state. That didn't work either.
I seems that on Android, if you want to change the drawable for one state of a button, then you must set all the states, and thus cannot preserve the default drawables for the other states. Is this correct?
Android :: Stop Following Activity If Home Key Or Pressed Back Pressed
Jul 8, 2010I have a problem and that is my SplashScreen I have. It is built as an intro and after 3 seconds it shows the main menu of the program. Anyway, if I press down Back or Home button during the time the SplashScreen shows, it closes, but the activity I have chosen to follow after the SplashScreen will still run after the three seconds.
My code: **UPDATED CODE**
Handler ur = new Handler();
myRun = new Runnable() {
public void run() {
mainIntent = new Intent(SplashScreen.this,MyApp.class);
SplashScreen.this.startActivity(mainIntent);
SplashScreen.this.finish();..........................
Android :: Changing Displayed State Of Views Based On Parent ViewGroup's State
Aug 11, 2010I have a compound UI component built up from a ViewGroup containing a number of TextView, ImageView etc. components. Many of these have StateListDrawables as their images/backgrounds. Is there any way of making them select from this drawable based on the state of the parent ViewGroup rather than the component itself? Ideally I want to be able to change the visual state of all children of the ViewGroup (text colour, image etc) based on the state of the ViewGroup, preferably without having to hook up complex logical code. This seems like a fairly common sort of requirement, so I was hoping it would be straightforward in Android - am I going to be disappointed?
View 1 Replies View RelatedAndroid :: Phone State Listener State Transitions
Feb 8, 2009I'm a little confused by what I'm seeing with regards to phone state transitions via the PhoneStateListener. When I receive a call, this is what happens: (call comes in) RINGING -> IDLE (I pick up) OFFHOOK (I hang up) IDLE It's that first transition from RINGING to IDLE without any interaction from me (not ending the call, not answering the call) that confuses me. Do I really have to implement an idle counter to know that an incoming call has really ended? Seems like the reported phone state represents some sort of phone state that isn't the obvious one.Is this a bug or am I just not in tune with the paradigm here?

Android :: Headset Button Is Being Pressed?
Jan 30, 2009Does anyone know how to tell when the headset button is being pressed? I'd like to support the usb headsets and possibly bluetooth headsets. My app is a media player and ideally, I could register it somewhere so that if no app that uses the headset button has focus it button press would act as a play/pause command in my app. If the phone is ringing or a call is in progress, I'd like to be sensitive to that and let the button do what it normally does: pickup and hang up calls. we've been trying to chase the button down using this: Intent Filter headset Filter = new Intent Filter (Intent.ACTION_HEADSET_PLUG); headset Filter.addAction ("android.intent.action.HEADSET_STATE_CHANGED"); headsetFilter.addAction("android.bluetooth.intent.HEADSET_STATE"); headset Filter.addAction ("android.bluetooth.intent.HEADSET_STATE_CHANGED"); headset Filter.addAction ("android.bluetooth.intent.action.MODE_CHANGED"); headsetFilter.addAction("android.intent.action.MODE_CHANGED");

View 2 Replies View RelatedAndroid :: Communicate Which Button Pressed?
Sep 30, 2009i have an app widget that has a couple of buttons on it, and in my onUpdate() call, I am hooking up the buttons to do something when you press them
RemoteViews remoteViews = new RemoteViews(context.getPackageName (), R.layout.appwidget); remoteViews.setOnClickPendingIntent(R.id.Button1, button1PendingIntent); remoteViews.setOnClickPendingIntent(R.id.Button2, button2PendingIntent);
The problem is that when I click on button2, it sends the button1 pending intent. i think that's because it's reusing the pending intent. http://groups.google.com/group/android-developers/browse_thread/threa. "If the creating application later re-retrieves the same kind of PendingIntent (same operation, same Intent action, data, categories, and components, and same flags), it will receive a PendingIntent representing the same token if that is still valid, and can thus call cancel() to remove it." So then the question is, how do I communicate which button was pressed?
Buttons Only Work After First Button Is Pressed?
Feb 13, 2012I have an xml page with 3 buttons on all leading to similar xml files. However, the second and third buttons only respond if the first has been pressed (and then you go back a page and press another). If I reverse the order of the buttons in the java file, which ever button is listed first is the one that has to be used befor the others.
Here is my java for the buttons:
package converter.units.kitchen;
import android.app.Activity;
import android.content.Intent;
[Code]....
the rest of the app has no errors and functions correctly.

View 8 Replies View RelatedAndroid :: Why Do Phone Buttons Stay Pressed?
Mar 21, 2010In my activity I respond to an onClick() by replacing the current view with a new one (setContentView()). For some reason when I do this and then go back to the original view later the button I originally pressed still looks like it is pressed. If you 'refresh' it somehow (e.g. scroll over it with the trackball) then it reverts to the unpressed state. It's as if the button doesn't get the 'touch-up' event. The weird thing is: This only happens on my T-Mobile Pulse (android 1.5). It doesn't happen on the emulator. I've tried calling invalidate()/postInvalidate() on the view when I show it but it doesn't have any effect.
