Answer 1

remove android:entries from your .xml file & define the string array into

String[] number = getResources().getStringArray(R.id.numbers);
ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, number);

Answer 2

Change to

String [] fiilliste;
ArrayAdapter<String> adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.verbs);
    fiilliste = getResources().getStringArray(R.array.fi); 
    // move this in onCreate

I assume you have the string array fi in strings.xml.

You probably got NullPointerException. You require activity context for getResources(). So move it inside onCreate.

here is what I did. i have created a string-array in array.xml

 <resources>
<string-array name="numbers">
    <item>1</item>
    <item>2</item>
    <item>3</item>
    <item>4</item>
    <item>5</item>
    <item>6</item>
    <item>7</item>
    <item>8</item>
    <item>9</item>
    <item>10</item>
</string-array>

and put a lisView in my xml layout

 <ListView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/listView"
    android:entries="@array/numbers"
    android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true" />

here is my MainActivity look like.

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemClickListener {

ListView listView;
String[] number;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    number = getResources().getStringArray(R.array.numbers);

    listView = (ListView) findViewById(R.id.listView);
    ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, number);
    listView.setAdapter(adapter);
    listView.setOnItemClickListener(this);
}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    TextView textView = (TextView) view;
    Toast.makeText(this, textView.getText() , Toast.LENGTH_SHORT).show();
}

}

Your problem is that the code should be put in on create or any other function. Not as static variable
