Android :: Modify Default Button State Without Affecting Pressed And Selected States?

Oct 4, 2010

I 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 :: Save State Of Droid Application When Back Button Is Pressed?

Sep 20, 2010

I 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.

Android :: How To Get Pressed State Of Preference

Sep 10, 2009

There 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 :: ImageButton With A Selected State?

Apr 9, 2010

If 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.

Android :: Set Selected State Of An Item In A Gallery (correct Way)?

Jul 24, 2010

I have a gallery that displays TextViews where the background of each view is the following code...

This selector work just fine for the state_pressed and default (idle) states, but the selected item state is never displayed. I REALLY do not want to force the background of the selected item by changing the background of the view when the onItemSelected event is called. What is the correct state or correct way to get the TextView background to be set properly. Is the selected (center) view in the gallery not really selected? Is there some other state I should put in the selector drawable xml?

Android :: Selected State Of WebView In A ListView Does Not Show Selection

Feb 3, 2009

Is there a way to show that a WebView item contained as a item in a ListView is selected? Right now the WebView does not seem to display its contents transparently like every other control so it takes up the entire view and does not show its state as selected.

Also, when the content of the WebView is selected, scrolling down with the track back does not seem to cause the WebView to loose focus. If I continue to scroll down with the track ball, all of a sudden an item in the middle of the ListView gets selected.

Android :: Headset Button Is Being Pressed?

Jan 30, 2009

Does 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");

Android :: Communicate Which Button Pressed?

Sep 30, 2009

i 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?
