I'm unlucky and I can not see my code now. As soon as I get back I see how I did it.

I use this:
B4X: 
@Override
        public boolean onDoubleTap(MotionEvent e) {
            processBA.raiseEvent(null, "ondouble_tap", index);
            return true;
        }
        public boolean onSingleTapConfirmed(MotionEvent e) {
            processBA.raiseEvent(null, "onsingle_tap", index);
            return true;
        }
        public void onLongPress(MotionEvent e) {
            processBA.raiseEvent(null, "onlong_tap", index);
        }

UPDATE:
Is it not always the way. I have struggled with this for ages and as soon as I ask for help the solution comes to me. Well a partial solution anyway. By destroying any previous head in Init_elements first it works. Every other place has generated an error. This at least allows me to create the latest head but I do not have the history of the previous ones on the screen. If you could help with that it would be fantastic. Thanks

Hi
I know that you are not actively involved with this anymore but I am trying to understand how the system destroys the standout created. I have generated a few heads (for want of a better word) and then try to destroy them. No matter what I do Only one is ever destroyed. The others stay in view untill the program ceases to run. I have moved the code from Service_destroy to a sub routine and I have tried to call it from various places. The result is always the same. Only the last one generated is destroyed. I have stepped through the code that removes the heads and it only ever goes through the loop once. Can you offer any advice as to why it does not work or how I could remove them
Many thanks for any replies

EDIT
I think I have realised the problem, Your code creates as many heads as is required immediately, What I have tried to do is make a call to the code and create a head when required and then when one is removed they are all supposed to be removed. However they are created in the map one at a time so there will only ever be one active at any time. I have then tried to destroy the one that is active before creating a new one but that does not work either. Any suggestions?

Yes and not . I also had some funny "variations" based on the original code and will now release one of them in the first post (I was just finishing to clean it), since it is good for me if people can play with it and make new things

About how to destroy them, you should keep a reference to each created object (in a map, list or array, depending on how your code works) and then call the destructor for each one of them (and remove from the list/map if you don't do it when you finish the service)

-EDIT- Just released it -

But if I extend the GroupView class instead of ImageView, would I be able to make a set of Views floating? How a floating panel? What do you think about it

B4X: 
public class CustomImageView extends GroupView {
     }

Yes, you can place a GroupView or derived class and place elements inside it.
Now I don't remember exactly, but something similar to what was done here

Thank's. But I think I arrived late, someone thought it long before me.

Hi @JordiCP, It is really helpful example. I have one question to ask you on how I use Panel view instead of Bitmaps to be displayed exactly same like GiF overlay?

Why it does not work by setting in the manifetst sdk_target = 26?

This message appears


But there is not this option on the device

Any updates on thoughts on how to allow dropping, which I assume means flinging it to the bottom to close the app?

Pretty cool, either way.

Sorry, now I see some pending questions which I didn't reply when they were made.

I haven't been into this project for months, and won't take it again in some time (that's why I released the source code) so my memory may fail me, but will try to answer what I remember.

B4A Panel Views are activity objects and this chathead is meant to work from a service so they will not work directly. Not sure since I still must test it, but perhaps you can take a look to OverlayWindow from Informatix's Pro Bundle.

The only problem that I am aware of, when using alert windows, is that in the later android versions they are seen as dangerous and need special permissions which don't work as the normal ones: you must go to a special settings page to manually allow it. I made THIS (also based on overlays) some time ago that handles the access to that settings page (look at the inline java part of the activity)

This would mean adding a second 'circle' that would move a bit (if we think of facebook messenger chathead) following the movement of the main chathead. It can be done in the gesturelistener of the inline java part, but requires time and someone to code it

Dear @JordiCP, permission request worked perfectly from SDK 23 up to 25
Unfortunately, by setting SDK_Taget = 26 a new problem arises.


Everything happens to this line of your code:

B4X: 
For Each descriptor As String In elements.Keys
        Dim num_instances As Int = elements.Get(descriptor)
        For k=0 To num_instances-1
            Dim myChatHead As chElement
            myChatHead.Initialize
            If descriptor="pic" Then myChatHead.ttype = PICTYPE
            If descriptor="drop" Then myChatHead.ttype = DROPTYPE

            myChatHead.active=True
            myChatHead.id=id
            ' -------------------   ERROR ON THIS ROW  -----------------------
            myChatHead.instance=J.RunMethod("newInstance2",Array(J,id))

            Dim Rect1 As Rect
            Rect1.Initialize(0,0,myChatHead.ttype.wwe,myChatHead.ttype.hhe)
            Dim bbb As Bitmap
            bbb.InitializeMutable(myChatHead.ttype.wwe,myChatHead.ttype.hhe)
            Dim cv As Canvas
            cv.Initialize2(bbb)
            cv.DrawBitmap(myChatHead.ttype.bitmap,Null,Rect1)
            If FloatingStandOut.WhiteCircle Then cv.DrawCircle(myChatHead.ttype.wwe/2,myChatHead.ttype.hhe/2,myChatHead.ttype.wwe/2-1dip,Colors.ARGB(200,255,255,255),False,1dip)
            myChatHead.instance.RunMethod("setImageBitmap",    Array(bbb))

            Dim xxe As Int = FloatingStandOut.X 'Rnd(0,a.Width-myChatHead.ttype.wwe)
            Dim yye As Int = FloatingStandOut.Y 'Rnd(0,a.Height-myChatHead.ttype.hhe)
  
            myChatHead.instance.RunMethod("mSetPos",Array(xxe,yye))
            'Add to the map
            myChatHeadsMap.Put(id,myChatHead)
            id=id+1
        Next
    Next

Just a guess based on some answers I've seen over there. Not tested but may be the cause

Look for the TYPE_PHONE or SYSTEM_ALERT string in the code where params is initted, and replace it by LAYOUT_FLAG, which should be defined as follows

B4X: 
// add these lines before the camParams initialisation
int LAYOUT_FLAG;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
   LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
} else {
   LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_PHONE;
}

params = new WindowManager.LayoutParams(
   <whatever there was here>,
   <whatever there was here>,
   LAYOUT_FLAG,
   <....>
   <....> );

Pls report results

Now solved.
Of course it is getting complicated .... From sdk 23+ you have to request a special permit, while from 26+ you have to change the flag

Add this
B4X: 
import android.os.Build;
Modified the code like this
B4X: 
private void sharedConstructing(Context context) {
        super.setClickable(true);

        this.context = context;
        windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);

        if (Build.VERSION.SDK_INT >= 26) {
           params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,//TYPE_SYSTEM_ALERT,
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
                PixelFormat.TRANSLUCENT);
        } else {
           params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.TYPE_PHONE,//TYPE_SYSTEM_ALERT,
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
                PixelFormat.TRANSLUCENT);
        }

        params.gravity = Gravity.TOP | Gravity.LEFT;
        params.x = 0;
        params.y = 100;

        windowManager.addView(this, params);
