Example 1: how to set list data to android spinner

// setting branch data in manually and load to spBranchName
        List branchList = new ArrayList<>();
        branchList.add("CHITTAGONG");
        branchList.add("DHAKA");

        ArrayAdapter branchListAdapter = new ArrayAdapter<>(getActivity(),
                android.R.layout.simple_spinner_item, branchList);
        branchListAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spBranchName.setAdapter(branchListAdapter);

Example 2: how to access a spinner from another activity in android

First save the position of selected data from spinner in a String variable,

int positionOfSelectedDataFromSpinner;

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView parent, View view, int position, long id) {
       positionOfSelectedDataFromSpinner= position;
}
Then on button click send intent to Another activity with putExtra

Intent i = new Intent (this, activity2.class);

i.putExtra("position", positionOfSelectedDataFromSpinner);
startActivity(i);
get int from getIntent in another activity

Intent intent = getIntent();
int positionToShowToSpinner = intent.getStringExtra("position");
then set the position to spinner

spinner.setSelection(positionToShowToSpinner);
