您好，我正在尝试向操作栏添加动画 View ，但我在 Android 2.3(适用于 Android 4)上遇到此错误

膨胀图像的代码是这样的:

LayoutInflater inflater = (LayoutInflater) getApplication()
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ImageView iv = (ImageView) inflater.inflate(R.layout.load_action_view,
        null);
Animation rotation = AnimationUtils.loadAnimation(getApplication(),
        R.anim.load_anim);
rotation.setRepeatCount(Animation.INFINITE);
iv.startAnimation(rotation); 

load_action_view.xml 是这样的:

<?xml version="1.0" encoding="utf-8"?>
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
    style="@style/Widget.Sherlock.ActionButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_action_load" />

做一些测试我注意到删除 style="@style/Widget.Sherlock.ActionButton"可以解决问题。

我在 list 中的应用程序标签是这样的:

<application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/Theme.Sherlock" >..</application>

你知道问题出在哪里吗？

修复了将 getApplication() 更改为此(它在 Activity 中)
