seekbar是android常用的一款手動滑動和自動滑動的滑動條控制元件，可以作為手動選擇數值的控制元件，也可作為進度條來使用，下面來介紹seekbar作為進度條的常用配置
一、樣式設定，在xml佈局檔案中引入下面的程式碼

 <SeekBar
         android:id="@+id/sb_quota"
         style="@style/mprogress_horizontal"//樣式
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
 

         android:thumb="@mipmap/bulegress_button" />//滑塊的圖示

style.xml

 <style name="mprogress_horizontal">
        <item name="android:indeterminateOnly">false</item>
        <item name="android:progressDrawable">@drawable/seekbar_horizontal</item><!-- 滑動條顏色-->
        <item
 
 name="android:indeterminateDrawable">@android:drawable/progress_indeterminate_horizontal</item>
        <item name="android:minHeight">5dip</item>
        <item name="android:maxHeight">5dip</item>
    </style>

seekbar_horizontal.xml

<?xml version="1.0" encoding="utf-8"?>
 

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@android:id/background"
        android:drawable="@drawable/seek_bar_secondaryprogress">
    </item>
    <item android:id="@android:id/secondaryProgress">
        <scale
            android:drawable="@drawable/seekbar_background"
            android:scaleWidth="100%" />
    </item>
    <item android:id="@android:id/progress">
        <scale
            android:drawable="@drawable/seekbar_progress"
            android:scaleWidth="100%" />
    </item>
</layer-list>

seek_bar_secondaryprogress.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/seek_background"/>
    <corners android:radius="20sp"/>
</shape>

seekbar_background.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/seek_background"/>
    <corners android:topRightRadius="20sp" android:bottomRightRadius="20sp"/>
</shape>

colors.xml

    <color name="seek_background">#FFcccccc</color>

二、滑動條的使用

private SeekBar sb_quota;
  sb_quota = (SeekBar) rootView.findViewById(R.id.sb_quota);
   sb_quota.setMax(maxAmount);//maxAmount為最大額度

三、滑動事件

 sb_quota.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
               //滑動中的監聽
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {
               //滑動後的事件
            }
