    spinner = (Spinner) findViewById(R.id.categoryList);
    btnViewExpenses = (Button) findViewById(R.id.btnViewExpenses);

    categoriesList = new ArrayList<Category>();

    //spinner item select listener
    spinner.setOnItemSelectedListener(this);

    new GetCategories().execute();

}

/**

private void populateSpinner() {
    List<String> lables = new ArrayList<String>();

// txtCategory.setText("");

    for (int i = 0; i < categoriesList.size(); i++) {
        lables.add(categoriesList.get(i).getName());
    }

    //Creating adapter for spinner
    ArrayAdapter<String> spinnerAdapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, lables);

    //Drop down layout style - list view with radio button
    spinnerAdapter
            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    //attaching data adapter to spinner

Verwenden Sie diese.

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position,
    long id) {

   String myStr = spinner.getSelectedItem().toString();
   selectedSpinner.setText(myStr);

}

@Override
public void onNothingSelected(AdapterView<?> arg0) {        
}

Versuchen Sie, diese..

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position,
        long id) {
    Toast.makeText(
            getApplicationContext(),
                    parent.getItemAtPosition(position).toString() + " Selected" ,
            Toast.LENGTH_LONG).show();

       String type = spinner.getSelectedItem().toString().trim();
       selectedSpinner.setText(type);

}

@Override
public void onNothingSelected(AdapterView<?> arg0) {        
}

Verwenden Sie Dieses.....

MainActivity.java

String[] text1 = { "SUNDAY", "MONDAY", "TUESDAY",
        "WEDNESDAY", "THURSDAY", "FRIDAY", "SATURDAY" };
int[] val1 = { 0, 1, 2, 3, 4, 5, 6};


Spinner  spinner1;
TextView  textView1;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    textView1 = (TextView)findViewById(R.id.text1);
    spinner1 = (Spinner)findViewById(R.id.spinner1);
    ArrayAdapter<String> adapter1 =
            new ArrayAdapter<String>(MainActivity.this,
                    android.R.layout.simple_spinner_item, text1);
    adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner1.setAdapter(adapter1);
    spinner1.setOnItemSelectedListener(onItemSelectedListener1);
}

OnItemSelectedListener onItemSelectedListener1 =
        new OnItemSelectedListener(){

            @Override
            public void onItemSelected(AdapterView<?> parent, View view,
                                       int position, long id) {
                String s1 = String.valueOf(val1[position]);
                textView1.setText(s1);
            }

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

        };

XML-CODE

    <Spinner
        android:id="@+id/spinner1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
    <TextView
        android:id="@+id/text1"
