I have a preferences screen that is populated with items from the database. It works for me, creating my own PreferenceActivity. In my work, I create elements DialogPreferenceand add them to my PreferenceCategoryTo style on the preference item on the screen. I use a custom layout and apply it withsetLayoutResource(R.layout.custom_pref_row)
This basically adds ImageButtonto the view aligned to the right of the layout. All this works great, and the settings screen shows a custom view with a button. My question is how to attach a click button to a button in a user view? I could not find a way to get Viewfor the string from PreferenceActivity. If my objects were not created dynamically, I could do all of this from XML, and then reference the identifier or button, but I can do this because I am dynamically creating the list.
Any suggestions on how to get a handle ImageButtonfor each item? In the end, I want to configure a button to launch the delete confirmation dialog box.
R.layout.custom_pref_row:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

Related part of my PreferenceActivity:
DialogPreference diaPref;
for (Station mStation : sList) {
diaPref = new StationEditor(this.getPreferenceScreen().getContext(), null, this, mStation);
diaPref.setLayoutResource(R.layout.custom_pref_row);
diaPref.setTitle(mStation.getName());
diaPref.setKey(STATION_PREFIX + mStation.getId());
// add new preference
stationTypesCategory.addPreference(diaPref);
}
