Question: I am using the SeekBar class provided by HoloEverywhere. I have the following imports:

```
import org.holoeverywhere.widget.SeekBar;
import org.holoeverywhere.widget.SeekBar.OnSeekBarChangeListener;

```

I get no preliminary errors or warnings, but when I compile, I get a class cast exception on the following line:

```
sectionTimeElapsedSeekBar = (SeekBar) findViewById(R.id.sectionTimeElapsedSeekBar);

```

Here is the corresponding XML:

```
<SeekBar
        android:id="@+id/sectionTimeElapsedSeekBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/startOrPauseTimerButton"
        android:layout_alignParentLeft="true"
        android:layout_marginBottom="16dp"
        android:max="2100" />

```

Anyone have any ideas?

Answer: 
Extend activity from org.holoeverywhere.app.Activity.
try importing:

```
import android.widget.SeekBar;

```

instead of 

```
import org.holoeverywhere.widget.SeekBar;

```
