示例1: NumberPickerPreference

//设置package包名称以及导入依赖的类
package be.mygod.preference

import android.content.Context
import android.content.res.TypedArray
import android.support.v7.preference.DialogPreference
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 = _

  {
    val a: TypedArray = context.obtainStyledAttributes(attrs, R.styleable.NumberPickerPreference)
    setMin(a.getInt(R.styleable.NumberPickerPreference_min, 0))
    setMax(a.getInt(R.styleable.NumberPickerPreference_max, Int.MaxValue - 1))
    a.recycle
  }

  def getValue = value
  def getMin = if (picker == null) 0 else picker.getMinValue
  def getMax = picker.getMaxValue
  def setValue(i: Int) {
    if (i == value) return
    picker.setValue(i)
    value = picker.getValue
    persistInt(value)
    notifyChanged
  }
  def setMin(value: Int) = picker.setMinValue(value)
  def setMax(value: Int) = picker.setMaxValue(value)

  override protected def onGetDefaultValue(a: TypedArray, index: Int): AnyRef =
    a.getInt(index, getMin).asInstanceOf[AnyRef]
  override protected def onSetInitialValue(restorePersistedValue: Boolean, defaultValue: Any) {
    val default = defaultValue.asInstanceOf[Int]
    setValue(if (restorePersistedValue) getPersistedInt(default) else default)
  }
  protected def getSummaryValue: AnyRef = getValue.asInstanceOf[AnyRef]
}

示例2: DividerAdder

//设置package包名称以及导入依赖的类
package com.android.perrier1034.post_it_note.ui

import android.content.Context
import android.content.res.TypedArray
import android.graphics.drawable.Drawable
import android.graphics.{Canvas, Rect}
import android.support.v7.widget.RecyclerView

    drawVertical(c, parent)
  }

  def drawVertical(c: Canvas, parent: RecyclerView) {
    val left: Int = parent.getPaddingLeft
    val right: Int = parent.getWidth - parent.getPaddingRight
    val childCount: Int = parent.getChildCount

    for (i <- 0 until parent.getChildCount) {
      val child = parent.getChildAt(i)
      val params = child.getLayoutParams.asInstanceOf[RecyclerView.LayoutParams]
      val top = child.getBottom + params.bottomMargin
      val bottom = top + mDivider.getIntrinsicHeight
      mDivider.setBounds(left, top, right, bottom)
      mDivider.draw(c)
    }
  }
}
