I’m using a spinner to show countries ID. Everything seems fine until I run the app and click on the spinner. After I click on the spinner the app crash.

Here’s my spinner xml code (which is inside a LinearLayout, if this is useful):

 <Spinner
       style="@style/mediumBlackDefault"
       android:id="@+id/spinner"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:layout_weight="4" />

And here’s how I populate it:

Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(  
                       getApplicationContext(),R.array.countries_array,
                       android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

Also this is the countries_array:

<string-array name="countries_array">
    <item>AE</item>
    <item>AF</item>
    <item>AG</item>
    <item>AI</item>
    <item>AL</item>
    <item>AM</item>
</string-array>

Finally I get these errors:

I’ve read all the posts available and none solved my problem.

Many thanks in advance!

    I would suggest you to try passing YourActivityName.this instead of getApplicationContext() as Context to your adapter.

    Are you using ActivityGroup or simple Activity?

    If you are using ActivityGroup, then it may cause problem of bad window token. Following post address the issue with ActivityGroup
