问题描述

我想更改默认的动画进度,所以我在我的主题添加自定义样式:

I want to change the default animation of a ProgressBar, so I added a custom style in my theme:

<style name="ProgressTheme" parent="@android:style/Widget.ProgressBar.Large">
    <item name="android:indeterminateDrawable">@drawable/spinner_holo_light</item>
</style>

我打电话这种风格在我的进度为以下内容:

<ProgressBar
    android:id="@+id/loadingProgressBar"
    style="@style/ProgressTheme"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

问题出在 spinner_holo_light.xml

如果我用下面的,一切工作正常与OS 3.0+设备,但进度不旋转在旧版本的操作系统:

If I use the following, everything works fine on devices with os 3.0+, but the progress does not rotate on older os versions:

<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/spinner_76_inner_holo"
    android:fromDegrees="720"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="0" />

但是,如果我用动画,旋转相反,动漫作品的每一个操作系统版本,但结果是非常laggy动画。

But if I use animate-rotate instead, the animation works on every os version, but the result is a very laggy animation.

<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/spinner_76_inner_holo"
    android:fromDegrees="720"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="0" />

你觉得呢?难道我做错了什么吗?

What do you think about it? Am I doing something wrong here?

推荐答案

在旧设备上这是一个问题,当安卓fromDegrees 大于机器人:toDegress &LT;转&GT; 。尝试交换的值:

On older devices it is a problem when android:fromDegrees is bigger than android:toDegress in <rotate>. Try swapping the values:

<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/spinner_76_inner_holo"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="720" />

另外,你可以尝试将其设置为无穷大:

Alternatively, you can try setting it as infinite:

<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/spinner_76_inner_holo"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatCount="infinite" />

动画可能是laggy对旧设备。为了解决这个问题添加安卓animationResolution 的风格:

<style name="ProgressTheme" parent="@android:style/Widget.ProgressBar.Large">
    <item name="android:indeterminateDrawable">@drawable/spinner_holo_light</item>
    <item name="android:animationResolution">33</item>
</style>
