Error connecting adapter for Spinner

When trying to connect an adapter:

Spinner spinner = (Spinner) findViewById(R.id.input_words_spinner_1); ArrayAdapter<?> adapter = ArrayAdapter.createFromResource(this, R.array.times, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); 

On the last line, the program crashes. Here is the array code:

 <string-array name="times"> <item>Один</item> <item>Два</item> </string-array> 

stacktrace errors:

Here is the Spinner a code:

 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@color/gray" android:orientation="vertical" > <LinearLayout android:layout_width="300dp" android:layout_height="45dp" android:layout_margin="3dp" android:background="@color/white" > <Spinner android:id="@+id/input_words_spinner_1" android:layout_width="match_parent" android:layout_height="45dp" /> </LinearLayout> <LinearLayout android:id="@+id/input_words_linearLayout_1" android:layout_width="300dp" android:layout_height="wrap_content" > <FrameLayout android:id="@+id/input_words_frameLayout_1" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="3dp" android:layout_marginRight="3dp" > </FrameLayout> </LinearLayout> <Button android:id="@+id/input_words_button_1" android:layout_width="300dp" android:layout_height="40dp" android:layout_margin="3dp" android:background="@drawable/button_background_one" android:text="@string/button_2" android:textColor="@color/black" /> </LinearLayout> 

What am I doing wrong?
