注：所有的進(jìn)度條都要配置
android:indeterminateDrawable="樣式文件名稱"
- 圖片旋轉(zhuǎn)
im_send_loading.png
注意：android:drawable屬性使用xml文件的圖片資源類型条舔，動畫可能會有問題(如閃爍)，尤其在高版本上，此時只能使用png等類型
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<rotate
android:drawable="@drawable/dialog_progress_round"
android:fromDegrees="0.0"
android:pivotX="50.0%"
android:pivotY="50.0%"
android:toDegrees="360.0" />
</item>
</layer-list>
或者
<?xml version="1.0" encoding="utf-8"?>
<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="@drawable/im_send_loading"
android:pivotX="50%"
android:pivotY="50%" />
2.幀動畫效果

<?xml version="1.0" encoding="UTF-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="false" >
<item

android:duration="150"/>
<item
android:drawable="@drawable/loading_02"
android:duration="150"/>
<item
android:drawable="@drawable/loading_03"

<item
android:drawable="@drawable/loading_04"
android:duration="150"/>
<item
android:drawable="@drawable/loading_05"

<item
android:drawable="@drawable/loading_06"
android:duration="150"/>
<item
android:drawable="@drawable/loading_07"
android:duration="150"/>
</animation-list>
