[android-developers] Re: AlertDialog OnKeyListener - How to get Focused Item?
I figured this out so I thought I would share. The handleKeyPress
method that is called from my OnKey handler is part of my Activity
object. So "this" is an activity not a dialog. So to get the focused
item is pretty simple, I needed to keep a reference to the AlertDialog
(mAlertDialog in the example):
public boolean handleKeyPress(DialogInterface dialog, int keyCode,
KeyEvent event) {
ListView lv = mAlertDialog.getListView();
if( lv != null ) {
int selectedPos = lv.getSelectedItemPosition();
Log.d("keyPress", "handleKeyPress : selectedPos: " +
selectedPos);
}
You also have to test for the right key and only choose the down
button action, but this is the part I had trouble with.

[android-developers] Re: AlertDialog OnKeyListener - How to get Focused Item?
I am thinking I need to override the dialog and track the position of
the focused item myself.
That seems kind of risky in case they ever get out of synch. Am I
missing something obvious?
Thanks!

[android-developers] AlertDialog OnKeyListener - How to get Focused Item?
I have an AlertDialog with an OnKeyListener. I need to find the
focused item when the Call key is pressed.
This AlertDialog also has an OnClickListener that works great - I get
the position of the item from my view when it is clicked.
What I also want to do - is get the position of the currently
highlighted (focused right?) item when the CALL key is pressed.
I can detected the CALL key event in my handler - no problem. But I
do not know how to get the item that had the focus when the key was
pressed.
Here is my OnKey handler and some of the things I have used to try and
get info
public boolean handleKeyPress(DialogInterface dialog, int keyCode,
KeyEvent event) {
Log.d("keyPress", "handleKeyPress :
this.getSelectedItemPosition(): " + this.getSelectedItemPosition());
Log.d("keyPress", "handleKeyPress : this.getSelectedItemId():
" + this.getSelectedItemId());
AlertDialog ad = (AlertDialog)dialog;
View fv = this.getCurrentFocus();
if( fv != null ) {
Log.d("keyPress", "handleKeyPress : fv.getId(): " +
fv.getId());
}
ListView lv = this.getListView();
if( lv != null ) {
View fvC = lv.getFocusedChild();
if( fvC != null ) {
Log.d("keyPress", "handleKeyPress : fvC.getId(): " +
fvC.getId());
}
int selectedPos = lv.getSelectedItemPosition();
Log.d("keyPress", "handleKeyPress : selectedPos: " +
selectedPos);
}
return false;
}
Thanks for your help!
