Question

I have created a Spinner and ArrayAdapter as follows:

Spinner spinner1 = (Spinner) findViewById(R.id.spinner1);
final ArrayAdapter<CharSequence> adapter1 = ArrayAdapter.createFromResource(
            this, R.array.units_array1, android.R.layout.simple_spinner_item);
adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter1);

The units_array1 is a string array declared in a xml file like this:

<string-array name="units_array1">
    <item>Centimeters</item>
    <item>Meters</item>
    <item>Kilometers</item>
    <item>Inches</item>
    <item>Foots</item>
    <item>Miles</item>
</string-array>

Now I want to implement some If-ELSE conditions that are based on the elements in string-array. I Have researched a lot on the internet for this but haven’t found out any solution that works. Please help me in implementing a function that returns the individual elements from the string-array using the adapter.

Answer 1

spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View v, int position, long id3) {
        final String scale = adapter1.getItem(position);
        // scale is gonna be "Centimeters" or "Meters", etc...
        if (scale.equals("Centimeters")) {
            // do something
        } else if (scale.equals("Meters")) {
            // do something else 
        }
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {
    }

});
