B4A Class Blank screen or splash screen

I had need to hide some screen manipulation including a keyboard showing, and came across some code on StackOverflow to add a panel directly to the window manager, which did the trick.

Here are two examples, and as I needed to run this at boot up, I've added the option to put a splash panel on top of it.

The panel passes through clicks, so if you are hiding buttons and edittexts, you will still need to cover them with a panel that has click and long click subs to consume the events.

The code I based it on can be found here:

http://stackoverflow.com/questions/...-lock-screen-turn-on-with-t/16034100#16034100

There are more options for animation if you search the Android developers site, and of course background colors.

An additional permission is required: Edit the manifest in the IDE and add:

B4X:
AddPermission("android.permission.SYSTEM_ALERT_WINDOW")

Excuse me, but a little because of my English a lot because of my lack of clarity, I'm not sure I understood.

I do not think you're referring to "normal" splash screen; you wrote:

"Directly to add a panel to the window manager",

which I guess is part of the OS and then you want to say that this method can display panels on external app?

I ask you this (although I could use your attachments and study their code) because it seems to me that some apps do this (they give even bother, to tell the truth).

The issue is that I would find a way to be able to write in the "EditText" of other apps, and despite the OS security perhaps a method exists to achieve this.

I am only slightly off topic, it is only a first impression!

This has nothing to do with 'other apps' the window manager is related to the apps context that is is added to, it is basically a system alert screen, hence the additional permission. It is not a normal splash screen in the sense that all manner of things, including keyboards, can be hidden behind it. But basically it adds a panel to the Window Manager, that panel can contain other views.

Maybe that's what I meant: "system alert screen".

I did not want to mention the app, I possibly delete its name, but Viber displays its messages on any app or on the Home, maybe using this your method. I was referring to this.

That is not possible with this method. As far as I know it only works with the app it's running in.
