方式1:(效果为补间动画一样)
android:layout_width=
"wrap_content"
android:layout_height=
"wrap_content"
android:indeterminate=
"true"
android:indeterminateDrawable=
"@anim/loading"
其中动画loading:
<?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)
<ProgressBar
android:layout_width=
"wrap_content"
android:layout_height=
"wrap_content"
android:indeterminate=
"true"
android:indeterminateDrawable=
"@drawable/progressbar"
其中progressbar:
<?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>
<!-- 其中360.0值越大,转的圈圈越快 -->
</item>
</layer-list>
方式三:(效果为自定义颜色让其不断的旋转)
<ProgressBar
android:layout_width=
"wrap_content"
android:layout_height=
