Dynamic Wifi Scanner with kivy

Question

I have made a small app for Android which is responsible for scanning Wi-Fi networks, the app works well, the problem is that I don't know how to add widgets every time there is a new network. What I want is that every time there is a new Wi-Fi network, a new widget appears with the data of that Wi-Fi network, I don't know if I explain myself, in my example I put several transparent buttons on the in which the button text is a wifi network, the bad thing about this is that when there are 4 or less wifi networks the buttons are still there, I want each new wifi network to add a button with the wifi network information,I'm still learning kivy I need help thanks!

Answer 1

You can replace the buttons in your kv string with a ScrollView containing a BoxLayout, then add a button to that BoxLayout for each network scanned. All the buttons can have the same on_press method, and that method can be similar to your info() method. The modified info() method would accept an arg:

def info(self, text):

That text argument could be the Button text attribute, and the info() method could look up the information about that network in a dictionary that uses that text as the key.
