Preferencescreen Class Not Found
I have this in preferences.xml
Solution 1:
You're getting confused, you're trying to set the preference definition as the layout definition. First set a layout for the Activity, then bind your preferences XML:
...
setContentView(R.layout.layout);
addPreferencesFromResource(R.xml.preferences);
...
Solution 2:
The setContentView is not for PreferenceScreen, just "addPrerencesFromResource(R.**.yourPreference);" well. And your activity for the yourPreference view should inherits PreferenceActivity but not Activity.
Solution 3:
You don't need setContentView() method in PreferenceActivity.
publicclassPreferencesActivityextendsPreferenceActivity {
@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
}
}
Although it's Deprecated. use Preference Fragments instead.
