Android自定义横向的ProgressBar

其实很简单，上代码！

在res下创建drawable文件夹，新建文件drawable/progressbar_color.xml

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

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

    <!-- 背景  gradient是渐变,corners定义的是圆角 -->

    <item android:id="@android:id/background">

        <shape>

            <corners android:radius="10dp" />

            <solid android:color="#ffffff" />

        </shape>

    </item>

    <!-- 第二条进度条颜色 -->

    <item android:id="@android:id/secondaryProgress">

        <clip>

            <shape>

                <corners android:radius="10dip" />

                <gradient

                    android:angle="90.0"

                    android:centerColor="#ac6079"

                    android:centerY="0.45"

                    android:endColor="#6c213a"

                    android:startColor="#e71a5e" />

            </shape>

        </clip>

    </item>

    <!-- 进度条 -->

    <item android:id="@android:id/progress">

        <clip>

            <shape>

                <corners android:radius="10dip" />

                <solid android:color="#FF8080" />

            </shape>

        </clip>

    </item>

</layer-list>

然后在布局中引用就可以了。

<ProgressBar

        android:id="@+id/my_progress"

        android:layout_width="match_parent"

        android:layout_height="12dp"

        android:max="100"

        android:progress="40"

        android:secondaryProgress="70"

        style="?android:attr/progressBarStyleHorizontal"

        android:progressDrawable="@drawable/progressbar_color"/>

还有一种是进度条样式加载图片：

1. <?xml version="1.0" encoding="UTF-8"?>
2. <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
3. <!--  设置背景色图像资源  -->
4. <item
5. android:id="@android:id/background"
6. android:drawable="@drawable/prgs_bg" />
7. <!--  设置进度条颜色图像资源  -->
8. <item
9. android:id="@android:id/progress"
10. android:drawable="@drawable/prgs_progress" />
11. </layer-list>
