I'm new to Android Studio and i have been trying to get the button to work but on my device it wouldn't show but on my design page it's there but no errors show up.
the design layout
the code
the AVD
Remove either layout_marginTop or layout_constraintVertical_bias attribute from the Button, according to the design requirements. Bias moves the button to the very bottom of the screen, and margin moves it event lower, out of the visible are.
P.S. do not trust AS layout preview, it lies sometimes :)

I noticed this half screen wifi selection menu in some Android Apps.
I would like to use this menu in my own app, to give the user the possibility to select the wifi without jumping to settings app.
I didn't find any instruction how to do this. However AndroidStudios Layout Inspector showed me that its belonging to the system, not to the app.
Anyone knows how to open this menu ?
It's called a Settings Panel:

You are looking for Settings Panel
This is for Android Q.
Here's an example to how to call it.
startActivityForResult(Intent(Settings.Panel.ACTION_INTERNET_CONNECTIVITY), INTERNET_SETTINGS_REQUEST)
I already made a button to be overlaid in the system window, only thing is I don't know how to take screenshot programmatically from that button to take screenshot of home screen or any other screen (not my activity).
What I want is how to programmatically run the combo keys to initiate the screenshot? (like pressing both power and volume down key at the same to take screenshot)
I know using adb command required root (which I don't want to), you can using getrootview but only inside your own activity (which I don't want to).
Since Android Lollipop (5.0) you can use MediaProjection to take screenshot.
I've this problem that my screen in Android Virtual Device is out of view. I have tried reducing the scaling by -0.75, as stated by others, but it doesn't seem to help.
Notice how the button to unlock the screen is out of view. How do I solve this issue?
You could use the context menu of windows. Right-click with your mouse on the AVD and chose move. Then your AVD should not be "locked" anymore (and maybe you can adjust the size then too).
I don´t know if it's possible, but I would like to know if it´s possible open widgets screen from a button inside in my app.
thanks and best regards.
You cannot bring app widget to home screen by code because Android not supported. Only by user action because you can not know does home screen has space to place widget.
I want to create a Draggable activity/fragment like the default settings screen in abdroid which opens when I pull down from HOme screen. By draggable i mean I want to pull the screen down from a point to close it.
I am trying to figure out the term used for this. I went through Drag views but that is used for moving view around the screen. Has someone solved this? Please help!
Android does not provide any API to support development of the settings-like screen. If you have to implement it, you will have to do that by yourself.
In order to fake the settings-like pull down screen within your application, you will need to create similar UI layout and use it in combination with the swipe down gesture (which works only when you swipe from the top within your application) and Animation.
Good place to start is to look on
DrawerLayout
It for drag layout into the screen and out.
A pretty good library that handle the stuff for you is:
