How to use a list of String instead of Resource Array in android

Question

I am using the following line of code currently and it works fine. I have an array called somearray declared under strings.xml

ArrayAdapter<CharSequence> adapter_teh = ArrayAdapter.createFromResource(AttendActivity.this, R.array.somearray, android.R.layout.simple_spinner_item);

However, I now wish to use List<String> instead of R.array.somearray. Basically, I am now getting a List from an API call which needs to be populated to the adapter_teh instead of the hardcoded array in Strings.xml

You can use ArrayAdapter<String> and pass your List<String> to adapter constructor, try below code

ArrayAdapter<String> adapter_teh = new ArrayAdapter<String>(AttendActivity.this, android.R.layout.simple_spinner_item, yourArrayList);

Hope this help you and solve your problem.

from resources

String[] yourStringArray = getResources().getStringArray(R.array.stringarray);

using String class

String[] yourStringArray = new String[]{"A1","A3","A4","A6","A7","A8"};

Common Adapter

ArrayAdapter<String> adapter = new ArrayAdapter<>(AttendActivity.this,android.R.layout.simple_list_item_1,android.R.id.text1,yourStringArray);

yes, edited, that should work, you just need to dynamically populate the string array now.
