方式1：(效果为补间动画一样)

[html] view plain copy

<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminate="true"
android:indeterminateDrawable="@anim/loading" />

其中动画loading:

[html] view plain copy

<?xml version="1.0" encoding="UTF-8"?>
<animation-list android:oneshot="false"
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:duration="60" android:drawable="@drawable/load_1" />
<item android:duration="60" android:drawable="@drawable/load_3" />
<item android:duration="60" android:drawable="@drawable/load_5" />
<item android:duration="60" android:drawable="@drawable/load_7" />
<item android:duration="60" android:drawable="@drawable/load_9" />
<item android:duration="60" android:drawable="@drawable/load_11" />
<item android:duration="60" android:drawable="@drawable/load_13" />
<item android:duration="60" android:drawable="@drawable/load_15" />
animation-list>

方式2：（效果为自定义图片让其不断的旋转）

[html] view plain copy

<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminate="true"
android:indeterminateDrawable="@drawable/progressbar" />

其中progressbar:

[html] view plain copy

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<rotate
android:drawable="@drawable/load"
android:fromDegrees="0.0"
android:pivotX="50.0%"
android:pivotY="50.0%"
android:toDegrees="360.0" />
<span style="white-space:pre"> span>
item>
layer-list>

方式三：（效果为自定义颜色让其不断的旋转）

[html] view plain copy

<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminate="true"
android:indeterminateDrawable="@drawable/progressbar2" />

其中progressbar2（在drawable文件夹下定义如下）:

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