Android: Create ArrayList from Spinner programmatically
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I have a spinner, created in an XML file:
<Spinner
android:id="@+id/unitSpinner"
android:entries="@array/units" />
With its entries defined in array.xml
<string-array name="units">
<item>g</item>
<item>kg</item>
<item>ml</item>
<item>l</item>
<item>szt.</item>
<item>op.</item>
</string-array>
Now in my Java file I want to create an ArrayList<String> which contents after feeding it with Spinner's entries would be:
["g", "kg", "ml", "l", "szt.", "op."]
My Java code looks like this:
Spinner unit = (Spinner) findViewById(R.id.unitSpinner);
ArrayList<String> array = new ArrayList<>();
//pass information from unit to array
EDIT:
This question differs from many questions like Android : Fill Spinner From Java Code Programmatically as I don't want to fill Spinner with an Array, but the opposite way.

This doesn't really make sense. You already know exactly what those values are. What is the point of building anArrayListfrom theSpinnervalues?

You can get the list from the XML array directly. no need to get ti from the spinner
String ss = getResources().getStringArray(R.array.units);
ArrayList<String> array = Arrays.asList(words);
if this aproach does not work with you you can try to get all the items fom the spinner via loop
for( int i = 0 ; i< unit.getAdapter().getCount() ; i++ ){
array.add ( ss.getAdapter().getItem( i ) )
}
Hope this will help.
