在pre蜂窝设备Android进度条缓慢旋转 [英] Android Progress Bar slow rotation on pre HoneyComb devices

问题描述

我一直试图实现pre蜂窝设备抽屉的转动平稳，但对我来说是不可能的：

I've been trying to achieve an smooth rotation of a drawer in pre honeycomb devices, but it was impossible for me:

在我layout.xml

In my layout.xml

<ProgressBar
    style="@style/ProgressBarLarge"
    android:layout_centerInParent="true" />

在styles.xml

in styles.xml

<!-- ProgressBar style -->
<style name="ProgressBarLarge" parent="@android:style/Widget.ProgressBar.Large">
    <item name="android:layout_width">@dimen/large_size</item>
    <item name="android:layout_height">@dimen/large_size</item>
    <item name="android:indeterminateDrawable">@drawable/progress_large</item>
</style>

最后，这里是我的绘制：

and finally, here is my drawable:

<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/spinner_green_76"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatCount="infinite"
    android:toDegrees="720" />

它工作在阿比11 +设备smoothy，但在pre ...它被禁止或缓慢...

It works smoothy on Api 11 + devices, but on pre... it gets barred or slowly...

我绝望了，我试图改变旋转抽屉，更改绘制资源到正确的API版本，但我无法得到任何

I'm desperate, I've tried to change the rotate drawer, change drawable resource to the right api version, but I couldn't get anything

推荐答案

要避免每次图像的处理，您可以$计算机页上$ P-过程中它们，然后使用的帧动画：

To avoid the processing of every image, you can pre-process them on your computer, and then use a Frame animation:

在XML中定义的动画，显示在顺序图像序列
  （如薄膜）。

An animation defined in XML that shows a sequence of images in order (like a film).
