Android Question How save a EditText reference?

rafaelmotaquintana · Jul 24, 2016

I have this situation.
This Sub gets an edittext as a parameter, and I need to know after an activity resume, which edittext was used

B4X:

Sub SaveSettings(lText As EditText)
     StateManager.SetSetting("bigtext",lText.Text)       
End Sub

After an activity resume, I need to restore the original edittext, and I don't know which is.
If only I could save the name of the edittext or some reference.

Just set lText.tag=xxxxx before. The you can check the value later.

I can't, its been used for another purposes. Besides, there are a lot of them and some are created in code, others are from layouts.

You have two options:
1. Use a custom type that holds all the things you need and set it as the Tag value.
2. Create a Map with the EditTexts as keys:

B4X:

Dim EditTextNames As Map = CreateMap(EditText1: "EditText1", EditText2: "EditText2")

Dim name As String = EditTextNames.Get(et) 'et is an unknown EditText

The first options is the one I prefer, but StateManager.SetSetting only saves string.

If I could save the object, then after activity resume I could use

SAVEDEDITTEXT = StateManager.getsetting(something)
SAVEDEDITTEXT.TEXT = StateManager.SetSetting("savedtext")

You cannot persist views.
