Android Question text box overflow

[Zeev Goldstein]

hi,

i use a textbox for entering data.
how do i prevent it from scroll when i enter a long string ?
currently after i type in a long string it will scroll down, i want it to keep in one line
it is not set to be multi line in the designer
when i am typing it is fine - all in one line but when i move to another field it scrolls

thanks

Does your text include an end of line character?

 

[Zeev Goldstein]

i think it has nothing to do with that as it also happen while i type
basically the data is read from a magnetic card reader but even if i just press 4 or any other char for some time it will happen
the msr finishes the entry with cr+lf but my manual entry is just charachters without any cr or lf in the end
it is somehow dependent on the text box...

Try this code:

Dim r As Reflector
r.Target = EditText1
r.RunMethod2("setHorizontallyScrolling", False, "java.lang.boolean")
r.RunMethod2("setMaxLines", 1, "java.lang.int")
EditText1.SingleLine = True

thanks Erel,

i put this code in sub Globals
it did not work
it didn't produce any error but also didn't change anything
have i missed anything ?

thanks

You should put this code in Activity_Create. Sub Globals should only be used to declare variables. I tested it on Android 4.3 and it doesn't scroll.

Also make sure that the EditText height fits a single line.

thanks.

sorry - i tried in Activity_Create but then i get error that the edittext is not initialized...

how do i set edittext height to fit single line ?
the text size is 25 height is 50. tried 25, 35, 40, 45 but the text was set to upper
changed to center and tried all options i could not set it to fit.

when i leave the field it is shown a bit up so i see the first part above the second part

also - when typing it cuts the entry and seems to start on clean but it is ok as the whole content is there
very odd - it should scroll horizontally...

edit:
i can't even initialize the edittext as it is not yet declared...
chicken and egg ?

solved.
had to bypass the problem any way as the display had to hide part of the field so i use a display field that holds the relevant data to show and the full content is hidden in another non display field.

thanks for your help and good will
