Java Android seekbar定制

我正在尝试定制和安装android seekbar（使用API 17），这样整个进度条线都是蓝色的

我在res/drawable中创建了以下XML：

draw\u seekbar\u settings.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <clip>
            <shape
                    android:shape="line">
                <stroke
                        android:color="@color/progressFxBar"
                        android:width="2dp"
                        />
            </shape>
        </clip>
    </item>
</selector>

更改绘图seekbar\u设置.xml如下：

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Define the background properties like color etc -->
    <item android:id="@android:id/background">
    <shape
                android:shape="line">
            <stroke
                    android:color="@color/progressFxBar"
                    android:width="2dp"
                    />
   </shape>
   </item>

  <!-- Define the progress properties like start color, end color etc -->
  <!-- if you want to change the progress edit following -->
  <item android:id="@android:id/progress">
    <clip>
        <shape>
            <gradient
                android:startColor="#007A00"
                android:centerColor="#007A00"
                android:centerY="1.0"
                android:endColor="#06101d"
                android:angle="270"
            />
        </shape>
    </clip>
    </item>
</layer-list> 



<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Define the background properties like color etc -->
    <item android:id="@android:id/background">
    <shape
                android:shape="line">
            <stroke
                    android:color="@color/progressFxBar"
                    android:width="2dp"
                    />
   </shape>
   </item>

  <!-- Define the progress properties like start color, end color etc -->
  <!-- if you want to change the progress edit following -->
  <item android:id="@android:id/progress">

                android:centerColor="#007A00"
                android:centerY="1.0"
                android:endColor="#06101d"
                android:angle="270"
            />
        </shape>
    </clip>
    </item>
</layer-list>
