Hmm...I am suffering with same problem.
why getView() returns unrelated view..
So..did you find any solution?
please refer below sample code.
preference_layout.xml
<LinearLayout
...
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/pref_cb"
android:onClick="onClickCheckBox"
android:layout_gravity="center_vertical"/>
/>LinerLayout
/xml/main.xml
...
<Preference
android:key="pref_key"
android:title="preference test"
android:layout="@layout/preference_layout"/>
PreferenceActivity.java
....
public void onClickCheckBox(View view) {
if(view != null) {
cb = (CheckBox) view.findViewById(R.id.pref_cb);
if(cb != null) {
Log.e("Activity", "Wow");
}
Log.e("Activity", "Check state:" + cb.isChecked());
}
}
Absolutely, onClickCheckBox() methos run when I click check box.
But, still I can't find the way how can get the root view of
LinearLayout.
If someone can have the solution that will be very useful tip.
Because we don't need to implement custom preference java source file
any more.
Have good weekend~~~~
