B4A Library ChatHead wrapper + GIF overlay

JordiCP · Jan 5, 2016

(2017/07/01)

Based on this wrapper, I also built some strange things on it, with different purposes. I am not working on most of them anymore, so I decided to share.

This one is funny. Similar to the video but with added elements

It combines several overlay elements and brings them into life simulating GIF animation (based on some previously converted GIF files to PNG) and sequencing them with a timer. In this version there are some xmas stars, a Santa and a spider skull

I publish it here since the thread already exists and is related to it... As always, perhaps the code style is not the best in the world to learn from, but I have tried to comment a bit and delete unneeded things so that it will be more easy to follow.

Important: in most recent android versions, you must grant directly to the app the permission to show elements on top of others (it is not enough with the declared manifest permissions). So, if nothing appears on your screen you should check it.

Hope you enjoy it
-----------------------------------

I'm happy to share this chatHead wrapper made with B4A and Inline Java. The original project is taken from here . I wrapped and modified it "a bit" for my purposes.

These views are not "normal" views in the sense that they don't need to be in an activity, but are added diectly to the WindowManager.
This allows for special uses, such as pop-up notifications which the user can interact with or simply discard. But also special care must be taken.

The attached zip is itself a small demo. All the "important" things are in the inline Java part in "oService", and how are they created and destroyed. The rest is just for the demo itself

Possibly many things can be improved, such as adding animations (I think in this case they are a bit tricky and still struggling with them)

Important: These views are not automatically destroyed when you destroy your app. Please pay attention at Service_Destroy

Also: the sound example in Files folder is from http://www.freesfx.co.uk/. It is free, but if you use it, they need to be mentioned

Enjoy!

(I am preparing the drop option as in facebook messenger, but will take a while )

Hi
I have modified the java code to accept a single tap and it works fine. However I am trying to add a long click event that does not work. the code is as follows

B4X:

public void onLongPress(MotionEvent e) { processBA.raiseEvent(null, "onLong_Press", index); }

Could you shed any light why this would not work? I have tried it both inside the public class GestureListener extends and outside of it. I do not get any errors thrown but it just does not respond
Many thanks for any help

Hello, To do it with just one click, what would the java code be like, since you have it with LonCklick.
Thank you!

Could you give a minimal example with a static picture?

peacemaker · Aug 10, 2018

Great code.
Any suggestion of a text popup menu sample after clicking over the head ?
Or simpler just open an activity ?

Thanks, Star-Dust, but sorry, it seems to me, that this code is more universal, and works under Android8+ directly, after Java code editing. Your lib, Star-Dust, depends much on latest changes in Android versions, and must be re-compiled.

Star-Dust · Aug 10, 2018

My library also works on Android 8.1 and does not need to be re-compiled because it already provides all the news on permiss-request.
Then using the same code the library checks the SDK version and if less than 26 does not ask for permissions, instead if it is equal to or higher than SDK 26 it asks for permissions.

but I had suggested the code you will find in the examples to open a menu after clicking the Head (floating button).
So look more at the example that the library and can help you for what you want to do

No, sorry
Notification code must be fixed\re-compiled.

How to block the possibility of dragging?
I mean to lock the button position.

Jarek I&Q · Apr 13, 2019

OK, I made it.
I don't know if I did it right, but the button is motionless now, just like I wanted it to.

I commented on that in the Java code:

B4X:

case MotionEvent.ACTION_MOVE: 
...

~~Try changing targetSDK version to 28 or higher in the manifest file.~~

Which Android SDK version are you using?

Ibrahim Saleh · Oct 31, 2020

That worked actually, changed the SDK to 28, and compiled fine. Thanks a lot.

The example isn't updated, possibly you need to change some of the things mentioned in the previous posts. (will do it when I have time)

You can take a look to @Star-Dust 's lib, I think this one is updated : https://www.b4x.com/android/forum/threads/sd-floating-button-standout.80847/

Maybe you need to ask for permission to float on the other apps. Erel gave a small example

Yes, that was the first thing I did, but it still doesn't work

JordiCP · Apr 12, 2021

Ok, Taking your modified project as reference, I only had to change the ~~TYPE_PHONE~~ --> TYPE_APPLICATION_OVERLAY to make it work
Also changed the Activity buttons background, otherwise the text was not seen

Santa is back!!!
