here is my code

MainActivity.java

Spinner spinnerk = (Spinner)findViewById(R.id.spinnercc);
String strk = spinnerk.getSelectedItem().toString();

if(strk.equals("A"))
    {
        k2 = 0.5;

                     android:layout_width="85dp"
                     android:layout_height="40dp"
                     android:layout_marginTop="5dp"
                     android:background="@drawable/button_section"

 final Spinner spinner_contact = (Spinner)               findViewById(R.id.spinner_contact);
    ArrayAdapter<String> adapter2;

    adapter2 = new ArrayAdapter<String>(getApplicationContext(),
            R.layout.spinner_contact, list);
    adapter2.setDropDownViewResource(R.layout.spinnerchecked);
    spinner_contact.setAdapter(adapter2);
    spinner_contact.setBackgroundResource(R.drawable.spinneredittext);

    spinner_contact
            .setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                public void onItemSelected(AdapterView<?> adapterView,
                        View view, int i, long l) {
                    cu_sp = list.get(i);
                     Toast.makeText(getApplicationContext(), cu_sp,
                     Toast.LENGTH_SHORT).show();
                }

                // System.out.println("vvvv selected"+myArraySpinner.get(0));
                public void onNothingSelected(AdapterView<?> adapterView) {
                    return;
                }
