How to associate event to a spinner selection

Question

I've created a spinner for my application. This is the code in the main.xml

 <Spinner android:id="@+id/sMenu" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="center" android:prompt="@string/base" />

and in my main class

 String [] base = {"Decimale", "Binaria", "Ottale", "Esadecimale"}; Spinner s1; s1 = (Spinner) findViewById (R.id.sMenu); ArrayAdapter adapter = ArrayAdapter.createFromResource(this, R.array.base, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); s1.setAdapter(adapter);

The program converts a number in binary, decimal, octal, hexadecimal. I want to associated some events to the spinner. For example, if I select in the spinner binary, in the edit text I can put only binary numbers. In which way I can associate this event to the spinner?

What did you try? Did you even try to find a solution before pasting that code here? — Tae-Sung Shin

s1.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parent, View v, int position, long id3) { final String b = adapter.getItem(position); // based on b you change the property inputType of your EditText // for instance, if b is 'deciaml' you set as inputType 'numberDecimal' } @Override public void onNothingSelected(AdapterView<?> parent) { } });

but in which way can indicate the position?

gwvatieri Over a year ago

the position is a parameter passed by the framework in the method ... onItemSelected(AdapterView<?> parent, View v, int position, long id3)...

but how can i associate the inputtype binary for example, with the string b?

gwvatieri Over a year ago

if ("Decimale".equals(b)). There is no other way unless you compare the position if (position == 0), but in this last case if then you move the set of values to arrays.xml you can't anymore.
