[android-developers] Re: problem accessing widget in Preference widgetLayout
findPreference finds the Preference, findViewById is what you want to
get the button/widget...
however, it seems (I had a similar problem) that the widget isn't
being created at the time you addPreferences in your onCreate method,
only later; presumably if you wrote a custom Preference subclass,
you'd be able to grab the widget just as it was loaded by overriding
onBindView, or some other method; or you could write a custom widget
class that performs any load-time action you need in
onFinishInflate(!). However, if you can wait until the preference is
clicked, an easier option is to use an OnPreferenceClickListener, at
which point the same findViewById call does work...!

I think you need to do findPreference instead of findViewById.
so like:
ib = (Preference) findPreference(displayimagekey);
Hope that helps.

Hi,
I can't seem to get a handle to the embedded widget (via widgetLayout)
in my preference.
My Preference XML is:
PreferenceScreen
xmlns:android=http://schemas.android.com/apk/res/android;
android:key=first_preferencescreen
EditTextPreference android:key=displayname
android:title=Display
Name
android:summary=Choose a
display name /
Preference android:id=@+id/displayimageview
android:key=displayimagekey
android:title=Display Image
android:summary=Select Display Image
android:widgetLayout=@layout/displayimage
/
/PreferenceScreen
My widget XML is:
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:layout_width=wrap_content
android:layout_height=wrap_content
android:orientation=horizontal
ImageButton android:id=@+id/displayimagebutton
android:layout_width=wrap_content
android:layout_height=wrap_content
android:padding=1dp
/
/LinearLayout
I'm trying to get a handle on the displayimagebutton to embed an
ImageButton in a preference row.
My java code is:
View v1 = null;
v1 = findViewById(R.layout.preferences);
ImageButton ib = null;
if (v1 == null)
Log.d(SUBSYSTEM_TAG, v1 = null);
else
{
ib =
(ImageButton)v1.findViewById(R.id.displayimagebutton);
}
I can't seem to get a view to the preferences I setup in
preferences.xml. in my OnCreate() I'm calling:
addPreferencesFromResource(R.layout.preferences);
and this seems to work fine since the preferences layout is
represented on the screen. However I can't get a View to this layout
as my java code is trying above, so I can find the embedded widget.
I've tried: v1 = findViewById(R.id.displayimageview);
but that just returns null also.
Any ideas on how I can get the ImageButton reference to my
displayimagebutton?
I'm really disappointed on the lack of an Android example for this.
Thanks!
