General :: How To Log Button Presses In Android
Nov 22, 2012
a hardware bug on my Samsung Galaxy S Plus.I'm writing this in the general forums since it doesnt seem to be a bug specific to the phone (no reports anywhere online) and the question itself is therefore not device specific.So i have a hardware home button on the phone which sometimes registers two clicks instead of one.On a 1sec press this would mean the following events:
- button down event
1sec pause
- button up event
- button down event
- button up event
So since this doesn't occur regularly and i want to somehow log presses of the home button and i dont know any way to do that in android.It doesn't need to run in the background but could be for example be opened specifically to test the button.

I am relatively new to this still, and I have been developing a small app that would benefit greatly from a user being able to press 2 buttons at one time. What is the best method for achieving this? I dont think that an OnClickListener works like that, and I have seen examples for doing this with an OnTouch event. However, I do not know how to set up button presses with an OnTouch event.

I am creating an Android service which constantly runs in the background. I'd like to be able to intercept calls to the power button to:
a) prevent the screen coming on
b) handle the power button press in a different manner.This is to enable the user to have a very simple interface to my application and prevent wasting battery powering up the screen when it is not required.
I will probably need an alternative mechanism to actually bring the screen back up (such as an extended key press or similar), but this only becomes relevant if what I'm after is possible.

I got a ListView item that contains a button inside. Currently the long press of a ListView item does not get processed. I thought that by setting the Button.setLongClickable(false) would allow the long press to be passed along to the ListView item and it's not happening.

First of all, maybe i went about this the wrong way in the first place. Situation is, i have a listview that when an item is clicked, it creates an intent and calls startActivityForResult() to another activity, to be able to edit the entries in the row. and that other activity after editing the required values, returns back to the calling activity, when the user clicks on a save button. The activity then uses the row Id to update the item.My problem now is that, if the user presses the BACK button instead, the application crashes. i have been looking around and see solutions like using Shared Preferences or onSavedInstanceState(), but i don't know where exactly i should be putting the code?

When I currently have my activity on the font of the screen, how can I make Android to 'destory' my activity when user clicks 'back' button? (i.e. onDestory of my Activity gets called)?

Following the samples and examples, I've successfully been able to load a model on screen and rotate it with the DPAD keys and overriding the onKeyDown method of the GLSurfaceView. Trying to use a letter though, causes a small box to appear at the bottom accepting the text that is being typed. What I'm not entirely clear on, is since I don't have a listener defined in the main Activity, why those key letter key presses are being intercepted by some other inherent listener(?). I setup an OnKeyListener for the view to call my own method and that does work... but I'm wondering if there is perhaps a better way to handle it.

I am trying to add a listener to my service that listens for volume key presses. I would like to act on presses even if my service is not in focus. Any idea how to do this? I have looked over the API, as well as performed google searches.

I am writing an activity where the user is supposed to some editing and is critical. In this activity, I dont want pressing of Call key to make it go to Call Log so I handle onKeyDown call back and there if the key pressed is Call, I just return true. That solves my problem. But, if Options menu is opened and then I press Call button, I am not getting control in onKeyDown.

Is there an app that will automatically press 1 when answering a call from someone who called the google voice number?I would prefer not to turn off 'call screening' because if my cellphone is off or doesn't have service (e.g. at work), any calls to my google voice number will go to voicemail instead of ringing my other phones.I recently learn off the Tasker app. Can this be configured to do this?

My MAIN activity is spawning a child activity that contains a ListView. While this ListView is being populated (through an AsyncTask), an indeterminate progress bar is shown.However, assuming that I am an impatient user and I press the BACK button, the progress bar is cancelled but I am left with a blank screen. I have to press BACK one more time to go back to the MAIN activity.I would like the app to go back directly to the MAIN activity by pressing BACK only once. Can somebody point me in the right direction? I am thinking I should call finish() somewhere but I don't know where to put it.

Can a program sit in the background and intercept keypresses, convert the keypresses from one letter to another, and send it to whatever program you are working in as though the new letter is what you typed?As qwerty is the only layout choice for hardware keyboards and I don't have root on my tablet, I want to use this as a work around.
If I were to press "s" on my hardware usb keyboard. The program would intercept the "s" before it got to whatever textbox and convert it into the dvorak key equivalent of "o". That o would then be passed to the program as a normal keypress.
if I were to press asdfg on the qwerty aoeui would be sent instead.I thought it best to ask before I waste hours trying to learn how to write the program.
List of changes I would make in a pseudocode case statement format.
Select Case Key
#Comment - Number Row Key changes
- = change to [
= = change to ]
#Comment - Top Row Key changes
q = change to '
w = change to ,
[code]...

When I'm looking at a web page or app the search key will from time to time light up, give haptic feedback and initiate the the search function on its own. Anyone else have this issue?

I purchased a Galaxy S through Bell in Canada a few days ago and it's been great, except for an issue that started just this morning. The phone keeps bringing up the context menu at random when I have not hit the key to do so. Sometimes I can use it for ten minutes without an issue, other times it will flip on/off repeatedly ever few seconds for a 15 second period or so. This is definitely not an issue of me pressing the key by mistake; I can lay the phone on the table and it will trigger the key on/off on its own.
I've tried:
- Cleaning the screen several times
- Rebooting
- Deleting pretty much every app I downloaded
- Total factory reset (from the boot menu)
After the factory reset the problem still exists, which leads me to believe it may be a hardware issue. I haven't seen any other posts regarding this issue, has anyone seen something like this before?

I have 3 activities in my app: Activity1 -> Activity2 -> Activity3. Inside Activity3, if the user presses Back, I would like to return to Activity2. In Activity3's onPause event, I added a finish() statement. That's probably not even necessary, but I wanted to make sure this Activity gets cleaned up. This works fine.
However, while in Activity3, if the user presses Home or starts a new app (through notification bar or some other means), I want both Activity3 and Activity2 to finish. If the user returns to this app, he should resume with Activity1.
I have figured out how to do one or the other, but I can't figure out how to handle both cases, if it's even possible. Can I trap the "Back" button in Activity3 and send a message back to Activity2 telling it not to finish()? It seems like the Activities follow the same lifecycle flow (Pause, Stop) regardless of what you do to send them to the background. Just to answer the question of why I want this behavior, imagine that Activity1 is a login screen, Activity2 is a selection screen, and Activity3 is a content screen. If I press Back from the content page, I want to be able to make a new selection. If I exit via any other means (Home, notification bar), I want the user to be "logged out".

On the iPhone, when you hold down the top button and the button on the bottom it takes a snap shot of your screen, I love that feature. Does the droid have it?

I'm trying to create an always-op-top button/clickable-image which stays on top of all the windows all the time. The proof of concept is here URLs...I'm following this example code URL....
I have been successful and have a running service now. The service displays some text on top left corner of screen all the time while user can freely interact with rest of apps in normal manner. What I'm doing is subclass ViewGroup and add it to root window manager with flag TYPE_SYSTEM_ OVERLAY. Now I want to add a button/clickable-image in place of this text which can receive touch events on itself. I tried overriding "onTouchEvent" for the whole ViewGroup but it does not receive any event. How can I receive events only on certain parts of my always-on-top view group?
Code:
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.graphics.Canvas;
[code]....

I like being able to wake the phone to view the lock screen using the home button at the bottom of the phone, but is there any way to make it so that a second click of that button, or a click of one of the others down there, will make it sleep again? Having to press the power button up top is just an inconvenience.

does anyone know if its possible or what app would be used to have the optical button work the same as the power button on the top of the phone. so if you push the button it would light the display up. or maybe its not even possible.

I tried searching for this but couldn't find a thread that discussed it. My power button appears as though its been jammed. I dropped my phone on its corner where the power button is but I don't think thats what the problem is. Anyhow, recently my power button responds but I have to really press it hard and it as though the button is jammed cause it doesn't depress as far.
My question is that is there a way to designate the camera button to become the power button? I know on some phones you can make different buttons do different things and I was curious if this was possible on the Droid.
