I am still playing around with my calendar, I already nearly managed to integrate the https://github.com/SundeepK/CompactCalendarView into one of my fragments. There is just one error left, i did some research, others got the problem too for example with ArrayList<>.
Example code:
final ArrayAdapter adapter = new ArrayAdapter<>
(this,android.R.layout.simple_list_item_1, mutableBookings);
The IDE says:
Error:(87, 38) error: cannot infer type arguments for ArrayAdapter<>
Note: C:...\Uebersicht.java uses or overrides a deprecated API. Note: Recompile with -Xlint:deprecation for details.
I already tried to recompile, but the result doesn't seem to work
Uebersicht.java:87: error: cannot find symbol
final ArrayAdapter adapter =
new ArrayAdapter<>(this,android.R.layout.simple_list_item_1, mutableBookings);
Uebersicht.java:87: error: cannot find symbol
final ArrayAdapter adapter =
new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, mutableBookings);
Uebersicht.java:87: error: package android.R does not exist
final ArrayAdapter adapter =
new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, mutableBookings);
I can post my full Fragment class too if it's necessary, it must be something with my API and the API the ArrayAdapter is using? Don't forget I am just a beginner, I am trying to do just some stuff all by myself.
You need to pass a Context to the Constructor of ArrayAdapter. You're actually in initializing it in a Fragment class, so this
is not valid as a Context. Try calling
final ArrayAdapter adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1,
mutableBookings);
