All, Forgive me I am a newbie for the Android world, I have a problem with the preference of IDE(ADT), Because The content assist short cut (alt+/) doesn't work for me. Please help to review it .thanks.
In the following code, I hope content assist can automatically make suggestions for me ,But it does't show anything when I press Alt+/. So far what I can do is right-click mouse, and select source\Override/implement methods... But I think it still seems verbose for overriding method. Is there any better way to make it? thanks.

Recently did a refreshers course in Android. I see that they changed a lot with the update. I have run into a few problems which I hope someone can help me figure out. The course gave me this code to be able to add in a button and make it activate for Android. However, this code is slightly outdated and I have attached the screenshot of the code I tried to fix according to what Andriod wants. think most of the problem is that with the new andriod sutidio I am working with this layout :androidx.constraintlayout.widget.ConstraintLayout
I would like to know in the ain activity how can I fix the problem in the screenshot attached to get this right. Please help because I can't move forward until I figure out the problem. I would like to know how do I change the "R" to the right code for constraint layout.
If you have error of R, then follow below steps.
Go to File menu in android studio and click on Invalidate cache / restart option.

Hey guys beginner in android studio here, basically my book rental is up and I am not sure of the name for something. In the tool bar of my fragment, I have a way to delete that fragment from the recyclerView. Everything works but I was wondering if someone could point me in the right direction of making a menu that pops up asking "are you sure you want to delete this?". I am almost positive I have seen it on here before as an example but I just cant seem to find it, probably because I am not entering the right search terms. Thanks for your time everyone!
I'm thinking you want to add a Dialog.
I would check out the documentation here.

Is there anyway to get a know when a keyboard (dis)appears?
Actually I'm trying to implement this
I haven't found anything which answers my question. I think I wasn't clear enough.
This
https://groups.google.com/forum/?fromgroups=#!topic/android-developers/nRaBoB8F54I
is a pretty old thread but it explains my problem pretty well.
I was wondering if there's any solution available to this now.
Please help. Thanks. :)
I'm not sure if this will work, you can try it and let me know. But if you put
android:configChange="keyboardHidden"
in your manifest for the activity, that will make it call onConfigChange of your activity passing it in a Configuration object where you can query the keyboardHidden member variable and see if its the same as it was last time or not. Note you will also have to check hardKeyboardHidden to tell if it was a slideout keyboard that went away or the software keyboard.
The problem is I know this works for pulling out the hardware keyboard. I don't know if it also calls you for displaying the software keyboard. Worth a try though.
I want to add an item in android builtin settings, for my application.
Can any body guide me through any tutorial or code that how can i acheive this?
Thanks a bunch in advance!
Something tells me this is not what you want... I don't know how to achieve it but I have a feeling if it is even possible, it wouldn't work on all devices. I'd stick to an in app settings menu like everything else. At least that way you know it's possible and will work on all devices.
