[Q] Remapping the trackpad

Hi, I was wondering if I could remap the trackpad button on my Droid Incredible to the home button. Kind of like how if you press the center button on the iPhone, it goes back to the home screen. Is this possible? and I do not want to flash another ROM. Thanks.

Uhm, this phone already has a "home" button.....

can't we just answer the question? sometimes ppl. I would assume if he has a dinc he knows about the home shaped icon under the screen there, with that said I've never seen this question asked b4 but would assume no bcuz of already in place "home" button

I know there is a button, but I want to use the track pad button for the same function.

I think this would be useful as well.

Look at the Optical joy stick wake thread. It's in the keymap file somewhere. I don't know what all you can remap it too but I know they remapped it to wake the device (though inconstantly but thats a sleeping problem)

Just a thought, but would you not loose all of the intended functionality as a result of doing this? For instance, how would you take a picture or record a video?

I have ruby rom so there already is a record button or camera button on the screen itself so it's not a problem.

Redemption rom use to have a tweak that let you hold down the search button key and it would start the camera application. This was done by editing the incredible-keypad.kl file in /system/usr/keylayout and changing the line "key 217 SEARCH WAKE_DROPPED" to "key 217 CAMERA WAKE_DROPED" i figure you could add a line "key 232 HOME WAKE_DROPPED" and get the home to open when the trackpad was pressed, but that didn't worked.
I've been trying to remap my trackpad to camera since I rooted my phone and still can't get the working. I hope this thread will spread some light on how to properly remap the DPAD_CENTER button.

Those two aplications remove the need for the trackpad button, however its usefulness doesn't end.there. the.ability to.scroll through text to edit without endlessly, 'push and pray' u get it in the right spot I would.imagine would get lost as well. The trackpad also can seek in some flash players too.

Okay. So this is not possible at all? Because i can edit text by zooming in on the website...
-steve

It doesn't seem to be possible... or if anyone has figured out how they don't want to share. Editing the kl files doesn't work like it does for other hardware buttons. Here's my thread asking the same thing:
[Q] Can't remap optical joystick?

would this be possible
if you were to look at the file text for the real home key maybe if you copy-pasted that txt into your trackpad txt file it would do the same function .......just a thought

Remapping soft keys

So I'm looking at remaping the soft keys (specifically the search) on the front of the phone. There appears to only be one "SEARCH" in the /system/usr/keylayout/vision-keypad.kl - key 217 (see code below) - that if changed has the following 2 effects:
1. Alters the functions of both the soft key on the front of the phone and the search key on the hardware keyboard. When I remap one, they both change to match your modification.
2. When changed, long press functionality of the soft key is lost. It will only accept a short press.
"SEARCH" can be successfully changed to "MENU", "BACK", and "CALL" (possibly others I have not tried) then pushed to the phone in recovery and function perfectly. However, when I map it to be the "POWER", the soft key does nothing on press, while the hardware search key on the slide-out works fine.
Has anyone found a way around this?
We remap the track pad to wake because we dont like using the top mounted power button, but it only does a half-ass job because when you want to shut the screen back off, you still have to reach for the power button. I think the track pad wake mod needs its own 'bacon bits'
Code:
# column 0
key 185 USER3 WAKE_DROPPED
key 100 ALT_RIGHT WAKE_DROPPED
key 217 SEARCH WAKE_DROPPED
key 28 ENTER WAKE_DROPPED
key 38 L WAKE_DROPPED
key 14 DEL WAKE_DROPPED
key 54 SHIFT_RIGHT WAKE_DROPPED

I think you're out of luck with regard to an easy fix. I just did a quick experiment with evtest and it looks like the softkeys on the screen are just areas of the touchscreen that the window manager treats specially and generates synthetic key events in response to touches on, instead of being actual mappable keys.

Well the are mappable. I managed to make it be the menu button and the back button just fine. It just doesnt want to be the power button..

The same key can be used as a single quick press or a long press. It is considered two different keys though. So you would have to figure out what the long press equivalent of the search button would be and change that one.

The way this thread can stay in developmental, is show steps on how you are remapping the keys.
For others to gain knowledge or this thread is moving to Q&A

Maybe I'm off here, but if I was making this post to show the steps, would that not fall under a "How To" or "Guide"? My goal here is development. Development –noun 1. the act or process of developing; growth; progress. Or in my case, I'm in the act/process of developing a remapped key file to make the search soft key into a power key, and to then share with the rest of the forum. My progress so far is that I've managed to map it to a menu key and a back key with no problems, and am reaching out to others for help as to why it is that when I change it to the power key, it doesn't accept my changes.
Its kinda a gray zone, in that if I were to successfully remap it to the power button and post the file here, it would, technically speaking, be less of a development thread than it is now - because it would be finished developing and instead, merely contain a file with instructions.
However, as requested, and for those who are interested:
The file you are looking for, is as mentioned in the OP, "vision-keypad.kl" and is located in /system/usr/keylayout. You can edit it with a text editor like Notepad++. The line that I am looking at, also refer to OP, is key 217.
I'm thinking now, after messing with it some more, that maybe because it is a soft key it cant be mapped to power, being that as soon as the screen shuts off it no longer functions... But then again there exists widgets that, upon press, turn off the screen and they function fine, so I see no reason this shouldn't. I'll keep you posted on what I find, and would appreciate any help in the mean time.

i'd love to be able to map a longpress menu and a longpress back action. Cyanogen 6.1 allows longpress back to be turned into force kill foreground process. So there is a way to capture longpress on those 4 keys, the question is, what does the system read that keypress as and how can it be mapped.

So it is doable! There are some .bin files in the /system/usr/keychar folder that correspond to the .kl files in the ../keylayout folder, but i havent been able to read them. Maybe thats it.. Gonna figure that out when I land tomorrow and get my computer set up

I changed the Search function key to Camera and it only works on a long press and I get no result on a short press. So maybe the function you are trying to rename the Search key to has to be specific to either way i.e. short or long press but not both.
So it will either work as a long press key for some functions or a short press key for others.

Read the window manager source (from AOSP or CM), determine what scancodes it synthesizes in response to touches or long-touches on the softkeys, edit keylayout accordingly.

Doesn't ButtonRemapper from Android App Dev section work on G2? :S

hey guys, i dont know if you all figured this out or not, I just got the g2, and to remap the key to power button you have to change it to "ENDCALL" not "POWER", after, reboot and voila! your search button now acts like a power button!!!!! Hope this helps!!!!!

Need to Map Back button to one of the soft key
Rceently I bought HTC Desire Z (no warranty), and I am facing the problem with 4 bottom buttons of the touch screen (menu, back, home and search). So I am planning to do hardware map for one of the softkeys to BACK button.
Could you please provide me step-by-step installation of all the softwares and the procedure I need to do for updating "vision-keypad.kl" file. Appreciate your help.
My one more doubt is that what is the difference between "WAKE_DROPPED" & "WAKE". I have seen these keywords in ".kl" file in GITHUB.
Please give me reply ASAP. I am frustrated with the way the mobile is working. Just imagine how it will be if back button stop working and you are in the middle of some application. I restarted my mobile some dozens of times.

CM9 - Keylayout camera button question...

So I've just installed CM9 ICS on my Samsung Epic 4G. The problem is, I want to add WAKE to the Camera button, however it is not listed in the "cypress-touchkey.kl" keylayout file. I figured I would change it in the Generic.kl file, but that doesn't seem to work.
In 2.3, the camera button was in keylayout, but this is not the case for CM9. I tried added the Camera entry with 212 on the cypress.touchkey.kl but no luck. What should I do?
Thanks in advance for any and all help.

I believe I saw that option in the settings somewhere

While I do appreciate the response, this in no way shape or form actually helps me. Let's say for instance that there is an option in Settings, saying "somewhere" doesn't really help. Second, I asked about the keylayout files. So even if there is a way to do this in the Settings page (which I don't think there is), I was still talking about keylayout files for a reason.
Sorry for sounding rude, but your response does not help me whatsoever. It's like saying that the answer is on the Internet... that's great and all and I'm sure it's on the Internet somewhere, but if I don't know where, then the answer is pretty pointless.

I apologize for my post and I was wrong anyway, there is no option. Sorry for taking your time

Solution
So after messing around with a few things, I finally found the solution which I will list below:
- To change Camera Button you need to edit s3c-keypad.kl
- To change Power Button, Vol+, Vol- you need to edit victory-keypad.kl
- To change soft keys (i.e. home button, menu, back, search) edit cypress-touchkey.kl
So to conclude, it is actually a combination of keylayout files. Please note that there are other listings for the buttons in various keylayout files such as Generic.kl, however do not edit these because they are not what the phone uses. I have tried almost all of the above keys and they have remapped successfully so long as you edit the key values in the .kl files listed above.
I hope this helps someone else who had the same problem.

soft keys layout change

does any one know how to change the key layout of the android sofy keys, i mean in a normal android or a nexus product, the soft keys goes in the order as ( First is the back button, then middle is home and last in the right is recent tasks button).
but in samsung s3 and note 2, when soft keys are enabled. The soft key layout is reversed. I mean the back button soft key which is supposed to be in the left is in the right , and the recent tasks button which is supposed to be in the right is in the left. Any one knows how to change the soft key layout?
anything to do with tht build.prop or the sys/usr/keylayout file?

I feel you mate.
Yes you are right go to sytem/usr/keylayout/generic.kl and swap 139 with 158 and reboot.
You need to use something like solid explorer that gives you root acces.
Have fun, W

Remap multitask to menu?

Any way to do this without root on the Note 4? I believe HTC offers this option on their M7 and M8 phones, so I really hope Samsung did the same since they switched it.

yes please! I believe it can be done but uncertain without decompiling the app doing some recoding and then recompile the results into a .apk file.

Hold the button down....it's menu with a long press of the multitasking button

haha me too i want menu one touch menu and recent long press of home button

I didn't realize the back button still did menu with a long-press. Glad to have learned that rather than having to search the 4 corners of the screen to see where the menu in whatever app is hidden.

When root is found, it should be a simple thing to flip the functionality of it right?
Also, anyone else wish there was a flashlight quick toggle in the notification tray?
