Goal: I am trying to use the RecyclerView to add EditText field(s) and PlaceAutocompleteFragment field(s)
Note: PlaceAutoComplete worked before adding the RecyclerView. Also, EditTexts work fine in RecyclerView, but once I try to use PlaceAutoComplete with it that's when I get the NullPointer Exception
Yes I googled and searched on stackoverflow for this error in conjunction with AutoPlacecomplete such as (Java null pointer exception on google places fragment) and (Didn't find class "android.view.fragment")
Full Error:
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void com.google.android.gms.location.places.ui.PlaceAutocompleteFragment.setOnPlaceSelectedListener(com.google.android.gms.location.places.ui.PlaceSelectionListener)' on a null object reference
at com.netgalaxystudios.timeclock.RegisterBusinessActivity.onCreate(RegisterBusinessActivity.java:119)
Line 119 refers to: autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
fragment from row_list.xml:
<fragment
android:id="@+id/place_autocomplete_fragment"
android:layout_width="0dp"
android:layout_weight="2.55"
android:layout_height="wrap_content"
android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"
/>
It seems like from my code that the PlaceAutocomplete is set, so not sure how its NullPointer (especially since it worked before using recycler view...) ??
