I have an ArrayAdapter as follows

ArrayAdapter<String>dataAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item);

This is the adapter which I am going to use for my Spinner.I have value sets (String array) for the Spinner in my strings.xml file.

How can I set the <string-array> in string.xml to the spinner pragmatically? Please help!

Just add it to your ArrayAdapter when you create it.

String[] yourArray = getResources().getStringArray(R.array.array_name);

ArrayAdapter<String>dataAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item, yourArray);

How to set selected item of Spinner by value, not by position , How to programmatically set drawableLeft on Android button? asked Jul 24, 2019 in Java by Nigam� How to set selected item of Spinner by value, not by position? (14) I have a update view, where I need to preselect the value stored in database for a Spinner. I was having in mind something like this, but the Adapter has no indexOf method, so I am stuck.

You can try something like this :

String[] mTestArray;
ArrayAdapter<String>dataAdapter;

mTestArray = getResources().getStringArray(R.array.testArray);
dataAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item,mTestArray);

and then attach the adapter to the Spinner.

spinner.setAdapter(dataAdapter);

Hope this helps!!!
