incompatible types: Spinner cannot be converted to String

Because source_lang and target_lang declared as String.

Use Spinner instead of String when declaring source_lang and target_lang variables:

Spinner source_lang;
Spinner target_lang;

you need to change String source_lang; to Spinner source_lang; and String target_lang; to Spinner target_lang;

Remove this line.

import static android.R.layout.simple_spinner_dropdown_item;

Try this,

ArrayAdapter<String> arrayAdapter1 = new ArrayAdapter<String>(getActivity(),
                    android.R.layout.simple_spinner_item, array_sourcelang);

ArrayAdapter<String> arrayAdapter2 = new ArrayAdapter<String>(getActivity(),
                    android.R.layout.simple_spinner_item, array_targetlang);
