ProgressBar 颜色的设置

转载自：http://blog.csdn.net/mars2639/article/details/6620836

布局文件代码：

<ProgressBar 
				android:id="@+id/progressbar"
				android:layout_width="wrap_content"
				android:layout_height="wrap_content"
				android:indeterminateDrawable="@drawable/progressbar"
			/>

此XML文件新建在drawable目录下：文件名为：progressbar

<?xml version="1.0" encoding="utf-8"?>
<animated-rotate
   xmlns:android="http://schemas.android.com/apk/res/android"
 android:pivotX="50%" android:pivotY="50%"    
 android:fromDegrees="0"  
 android:toDegrees="360">
    
    <shape 
     android:shape="ring" 
     android:innerRadiusRatio="3"  
  android:thicknessRatio="8" 
  android:useLevel="false">  
  <gradient 
   android:type="sweep" 
   android:useLevel="false"  
   android:startColor="#6BD3FF"         
    android:centerColor="#FF7121"  
   android:centerY="0.50" 
   android:endColor="#FFFF00" />  
 </shape>  
    
</animated-rotate>

至于设置水平进度条的颜色:

	<LinearLayout android:gravity="center"
		android:orientation="horizontal"
		android:padding="10dp" 
		android:layout_width="fill_parent"
		android:layout_height="wrap_content">
		<SeekBar android:layout_gravity="center" android:id="@android:id/progress"
			android:paddingLeft="8.0dip" android:paddingRight="8.0dip"
			android:paddingBottom="4.0dip" android:layout_width="fill_parent"
			android:layout_height="wrap_content" android:maxHeight="2.0px"
			android:progressDrawable="@drawable/progressbar_drawable" android:minHeight="2.0px"
			android:thumb="@drawable/seekbar_thumb" style="?android:attr/progressBarStyleHorizontal" />
	</LinearLayout>

progressbar_drawable.xml如下：

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background">
        <shape>
            <corners android:radius="2.0dip" />
            <gradient android:startColor="#ff000000" android:centerColor="#ff000000" android:endColor="#ff000000" android:angle="270.0" android:centerY="2.0"  />
        </shape>
    </item>
    <item android:id="@android:id/progress">
        <clip>
            <shape>
                <corners android:radius="2.0dip" />
                <gradient android:startColor="#ff33b5e5" android:centerColor="#ff33b5e5" android:endColor="#ff33b5e5" android:angle="270.0" android:centerY="2.0"  />
            </shape>
        </clip>
    </item>
</layer-list>
