Has anyone seen a a onItemSelected not being called when using a spinner inside a listviewActivity. I have the code below Inside a listViewActivity. The spinner is shown on screen by pressing a button (not the spinner) which in turn calls performClick() on the spinner. When I select an item from the spinner the onItemSelected function is not called. Does anyone know why this might be? Code...

I have a pattern unlock on my Samsung Galaxy S 19000. If I want to lock my screen manually I simply press the power button briefly which works fine. I now use a skin on my phone which doesn't allow for easy access to this power button so I'm wondering if there's an app that I can use to lock my phone screen without having to press the power button. I have looked at "lock 2.0", however, it seems to be more for actually unlocking the screen.

I just got the vibrant about a week ago, and so far no major issues. Still fumbling around in the apps market for the good stuff. One thing I found annoying was having to press the power/unlock button and then swiping the screen to unlock the phone every time, is there anything in the market or some setting to avoid pressing the button and just swiping the screen or possibly using the touch buttons on the front of the phone then swiping?

However,it seems very easy for the side buttons to be pressed, even when the phone is locked. What do you all do for this? I have tried a couple things and did find a "solution", but it's not one that I like, and would appreciate hearing thoughts from others.
View 4 Replies View RelatedI'm new to Android and just starting the very basics. I implement my custom button skin using .9.png images for norma/focus/pressed states. It works fine, but I noticed that after a pressed the focussed button it visually "lost" focus and draws the normal state frame. I planned to use different state images to highloght what button is selected right now, but it seems that it would not work. I noticed also that the same happens with the default LAF button. Is it OK, or it's just emulator issue? What the good workaroud can be used?

View 1 Replies View RelatedWhen i leave my app after pressing home button and then re launch it from menus it behaves in a strange way.Sometimes it launches the same activity on which i pressed home button.But sometimes it launches the first activity of my app. One reason for this could be that whenever system has memory shortage it clears any activities existing in But the strange thing is if i press back button from first activity it takes me back to the same activity on which i pressed home button and all other previous activities are also there(like if i press back button again previous activities also exist.)I haven't set any launching mode for any activity in my app(like single instance etc).What i don't need is that previous activities load on pressing back button on first activity.

Is there any way to make it so when i press and hold the power button and choose either silent or vibrant only that it will also mute media? I am hoping for the ability to change something through adb shell or something because I use the power button method all the time I just really want it to mute/unmute the media volume too.
View 3 Replies View RelatedWhen I'm talking, my hair tends to press the mute button on the home screen and the other person cannot hear me. I've searched but can't find a way to make this stop. An app, a better phone-holding technique--I'll try just about anything. Also, for some reason I had a glitch the other day... I made a phone call, got my friend's voicemail, and then was unable to hang up the call. I ended up leaving a rather long, embarrassing voicemail message until I just went in and force stopped the dialer app, but at least my friend has a good sense of humor.

I find the power button to be annoying and wish both would "wake-up" the screen.
i focus my eyes on /sys/class/leds/button-backlight/, however, i can just turn off the backlight.
i found that the trigger in it can do complex work, so i tested it, and found some codes below
Code:
[none] rfkill0 mmc0 mmc1 mmc2 timer heartbeat sleep rfkill1 rfkill2 max8903a-usb-online max8903a-ac-online battery-charging-or-full battery-charging battery-full battery-charging-blink-full-solid
however, i haven't found the one i want.
Anyways, whenever i'm listening to music, and I press the play/pause button on my headset to control my music tracks, my phone turns on. This get's really annoying because every time my phone turns on, it stays on for a few seconds, and this really kills battery life. I've tried lurking around my phone's settings and even my launcher settings.
My phone is a rooted HTC Wildfire S running AOKP custom rom with Nova Launcher Prime. And if it makes any difference, I'm using the "Start" lock screen from the Play Store.
As the title says, i have a Spinner with just a couple of options and a button. I didnt declared any Listener for the spinner, instead of that, what i want is use the button and perform different actions depending on the spinner selected option.
So, i declared a handler in the button option "android:onClick", but once there, i dont know how to access the option selected in the Spinner.
i have a spinner with an arrayadapter that is dynamically managed. when it gets displayed, the spinner text also displays the radio button. how do i get rid of this radio button?
NOTE: i'm not talking about the radio buttons that appear in the list that is displayed when i select the drop down on the spinner.
here is a pic of what it looks like: SIGH cannot upload image as i don't have 10 pts. so i've found a link: http://www.slashresources.com/android-gui-examples/ scroll down about 1/2 way and find the spinner example on that page. and my spinner looks like the spinner thats grayed out by the list. notice how the drop down arrow is all strecthed and yucky... thats my problem.
Here are the appropriate code snippet... couple of points:
This code is in the constructor of widget which is a subclass of Spinner value is an array of Object instances (passed when the widget gets created) there are no XML resources; all widgets are dynamically created thinking i need to "manipulate" the prompt, i added setPrompt(...) in the constructor and also in the onitemclicked event listener... this had no effect.
Q: what am i missing? seems to me i'm missing some attribute of the Spinner which is causing the radio button to also display in the text part of the spinner.

View 1 Replies View RelatedReceived my 2.1 OTA at 1:36 AM last night and ever since, I can't manually lock my phone by short pressing the power button anymore. I thought maybe this was a Spare Parts issue, since I had changed the Power Button behavior on 1.5 using Spare Parts (when I pressed Power from any screen, it would return me Home; pressing from Home would Lock). So, I uninstalled Spare Parts, but this didn't remedy my problem. Any advice?

I am trying to populate a TextView based on the current selected options in 3 Spinner(s) but cant seem to figure out how to retrieve the selected values from the Spinners to invoke the update function with.
Here is my current code (quite messy but I'm just learning Java,

calcButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks
AgeFun.updateAge(year, month, day);
// Month spinner
spinnerMonth = (Spinner) findViewById(R.id.spinnerFirst);
monthAdapter = ArrayAdapter.createFromResource(
this, R.array.monthList, android.R.layout.simple_spinner_item);
monthAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerMonth.setAdapter(monthAdapter);
// Day spinner
dayNames = new String[31];
for(int i =1; i <= 31; ++i)

View 1 Replies View RelatedMy question is about restoring complex activity related data when coming back to the activity using the "back" button". Activity A has a ListView which is connected to Array Adapter serving as its data source - this happens in on Create(). By default, if I move to activity B and press "back" to get back to activity A, does my list stay intact with all the data or do I just get visual "copy" of the screen but the data is lost? What can I do when more than activities are involved? Let's say activity A starts activity B which starts activity C and then I press "back" twice to get to A. How do I ensure the integrity of the A's data when it gets back to the foreground? Prefs Manager does not seem to handle complex object very intuitively.
