1.水平进度条

问题一：如何这种进度条颜色

drawable文件夹下创建进度条样式文件progressbar_bg.xml

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">    <!--3个层的顺序即为显示时的叠加顺序-->    <!--背景色-->    <item android:id="@android:id/background">        <shape>            <corners android:radius="5dip" />            <solid android:color="#CCCCCC" />        </shape>    </item>    <!--二级进度条的颜色-->    <item android:id="@android:id/secondaryProgress">        <clip>            <shape>                <corners android:radius="5dip" />                <solid android:color="#88F56100" />            </shape>        </clip>    </item>    <!--一级进度条的颜色，也可以直接替换成图片-->    <item android:id="@android:id/progress">        <clip>            <shape>                <corners android:radius="5dip" />                <solid android:color="#F56100" />            </shape>        </clip>    </item></layer-list>

布局文件中使用进度条

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="match_parent"    android:layout_height="match_parent">    <ProgressBar        android:id="@+id/progress_bar"        style="?android:attr/progressBarStyleHorizontal"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginTop="100dp"        android:minHeight="20dp"        android:padding="10dp"        android:progressDrawable="@drawable/progressbar_bg" /></LinearLayout>

问题二：单一颜色不好看，如何设置渐变颜色

修改progressbar.xml样式文件就行了

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >    <item android:id="@android:id/background">        <shape>            <corners android:radius="5dip" />            <gradient                android:angle="0"                android:centerColor="#ff5a5d5a"                android:centerY="0.75"                android:endColor="#ff747674"                android:startColor="#ff9d9e9d" />        </shape>    </item>    <item android:id="@android:id/secondaryProgress">        <clip>            <shape>                <corners android:radius="5dip" />                <gradient                    android:angle="0"                    android:centerColor="#80ffb600"                    android:centerY="0.75"                    android:endColor="#a0ffcb00"                    android:startColor="#80ffd300" />            </shape>        </clip>    </item>    <item android:id="@android:id/progress">        <clip>            <shape>                <corners android:radius="5dip" />                <gradient                    android:angle="0"                    android:endColor="#8000ff00"                    android:startColor="#80ff0000" />            </shape>        </clip>    </item></layer-list>
