I have two Spinners. In onCreate
i setup listeners for them. At some other places i populate them.
Now I am not sure what the best practice is for handling these spinners when screen orientation changes. Should i store all values and selected item in sharedPreferences
somehow or in savedInstanceState
?
If you can, please advise me in a prefered way and also include some sample code for handling spinners. The goal here is to keep the values and selected item thru the lifecycle.
I will include code at request or if needed.
Thanks
Add android:configChanges="orientation|screenSize"
in your AndroidManifest file, it will keep spinner value selected on orientation change.
User Spinner Like this:
mSpinner = findViewById(R.id.spinner);
ArrayList<String> stringArrayList = new ArrayList<>();
for (int i = 0; i < 6; i++) {
stringArrayList.add("List Item " + i);
}
ArrayAdapter arrayAdapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, stringArrayList);
spinner.setAdapter(arrayAdapter);
