Android Question How to save settings?

[trueboss323]

How can I save my settings inside my app. In VB.NET you use

My.Settings

and you can change what type of value (String, Boolean, Integer, etc)
What is the easiest way I can do that in B4A ?

Hi,
I looked at the library. Could you please provide an example?
Say that I want to save a simple textbox like My.Settings.text = TextBox1.Text
and then load it like: TextBox1.Text = My.Settings.text
Whats the best way i can do that?

StateManager is very easy to use.

Thanks. I'm still trying to figure out how I could save booleans like checkboxes, I can't seem to find the proper code for saving, and loading them.
Could you provide some help please ?

I never worked with checkboxes but I guess it will be something like

'load or set first time defaults
StateManager.loadStateFile
chkOption1.checked=StateManager.GetSetting2("option1",0)

'saving
StateManager.SetSetting("option1",chkOption1.checked)
StateManager.SaveSettings

StateManager.SaveSettings

I have tried your code and unfortunately that didn't work for me.

worst case you can solve it with if/then's

'load or set first time defaults
StateManager.loadStateFile
if StateManager.GetSetting2("option1",0)=0 then
chkOption1.checked=false
else
chkOption1.checked=true
end if

'saving
if chkOption1.checked=false then
StateManager.SetSetting("option1",0)
else
StateManager.SetSetting("option1",1)
end if
StateManager.SaveSettings

Thank you! That one worked. And do you also know how I can do the same with text and labels? Since I'm not sure if StateManager.SetSetting("text1",1) would work with Strings.

 

[sorex]

the first is the paraeter name, the second the value so you could use

StateManager.SetSetting("text1",editText1.text)

StateManager SetSettings is indeed very simple to use. However you should also check KeyValueStore class which is simple and much more powerful.
