import android.util.AttributeSet
import android.view.ContextThemeWrapper
import android.widget.NumberPicker
import com.github.shadowsocks.R
class NumberPickerPreference(private val context: Context, attrs: AttributeSet = null)
extends DialogPreference(context, attrs) with SummaryPreference {
private[preference] val picker = new NumberPicker(new ContextThemeWrapper(context, R.style.NumberPickerStyle))
private var value: Int = _
