How to set EditText Background to Colors.Transparent

 

[LucaMs]

EditText1.Color = Colors.ARGB(0,0,0,0)

The above code will not work properly as it will replace the EditText drawable with a simple color drawable.

It should be transparent by default if you set the targetSdkVersion to 14.

Have you tried it?

 

[LucaMs]

EditText1.Color = Colors.ARGB(0,0,0,0)

It seems to work

 

[Erel]

I didn't mean that it will not work. As I wrote it will replace the default drawable, which is not a simple color, with a ColorDrawable.

On Android 4+ the "correct" look of EditText is a thin line with a transparent background. I thought that this is what the OP wants to achieve.

 

[LucaMs]

Indeed, the rectangle does not appear (I think you mean this).


P.S.
No, you mean the line similar to an underscore; but I understand what you mean, the EditText will lose its appearance

is it possible to set background to one color on focus and to another color when lost focus ?
this is a way to let the user know where he is on the data entry flow
it can also be used to indicate for mandatory field (for example light red background) or optional (light yellow)
when focus on the field to paint the background and when lost focus to return it to whatever it was...
is this possible ?

Place the edit text in a Panel, set the panel to transparent and play with canvas and drawable to change the border color/width...

 

[Zeev Goldstein]

thanks,
seems not very friendly as it will require each edit text into a panel and that's quite a hustle
i am more into changing the background similar to vb.net for example

 

[Cableguy]

You could create it as a custom view, and expose the necessary properties, it would then act as a single view

 

[Zeev Goldstein]

thank you.
i will look into it
