How to make Views in a GridView hightlight-able by keyAction

sommeralex · by **sommeralex** » Sun Mar 02, 2008 8:22 am

Hello! And nice sunday..

I have no idea how to to implement focusable / selectable (android makes differences here) on GridView elements. What i mean, sounds simple:

There is a GridView, and i want Views to be added (works for me)
But, i also want them to be highlighted if i move the buttons on the phone (so, for mobile phones without touchscreen)

hm..
and help as highly welcomed.
alex

ps: the coolest thing would be a custom selection layer to draw on the selected item.

exactly..

i also set my views (they are all the same) to

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
setFocusable(true);
 
Parsed in 0.030 seconds,  using GeSHi 1.0.8.4

but this doesnt change anything.. myView extends linearLayout - mybe this causes some troubles.. ?

Hello sommeralex,

I haven't done such a thing before, but I would start trying with :darrow:

in your custom View:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

        @Override
 
        protected void onFocusChanged(boolean focused, int direction) {
 
                // TODO Auto-generated method stub
 
                super.onFocusChanged(focused, direction);
 
        }
Parsed in 0.030 seconds,  using GeSHi 1.0.8.4

thx for your answer.. the trouble is... there is nothing - no selection-rectangle at all..

Hello sommeralex,

yes I understood.
But within that function you could alter the background-color of the LinearLayout and/or the Children.

i got the "bug" - i dont know why - nor if it is really a bug, but for me, it sounds like one.

i added the adapter BEFORE adding any elements to the adapter itself. therefore, i had not the standard-selection function elements (views) have.

but anyway, thanx you very much for your suggestions..
