NPE同时在老Androids上充气ActionBarSherlock
我正在使用ActionBarSherlock并遇到可怕的问题：
01-08 22:16:05.803: E/AndroidRuntime(432): java.lang.RuntimeException: Unable to start activity ComponentInfo{ar.android.app.glarm/ar.android.app.glarm.gui.GLarmMain}: android.view.InflateException: Binary XML file line #32: Error inflating class com.actionbarsherlock.internal.widget.ActionBarView 01-08 22:16:05.803: E/AndroidRuntime(432): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1736) [CUT] 01-08 22:16:05.803: E/AndroidRuntime(432): Caused by: android.view.InflateException: Binary XML file line #32: Error inflating class com.actionbarsherlock.internal.widget.ActionBarView 01-08 22:16:05.803: E/AndroidRuntime(432): at android.view.LayoutInflater.createView(LayoutInflater.java:596) 01-08 22:16:05.803: E/AndroidRuntime(432): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:671) 01-08 22:16:05.803: E/AndroidRuntime(432): at android.view.LayoutInflater.rInflate(LayoutInflater.java:724) 01-08 22:16:05.803: E/AndroidRuntime(432): at android.view.LayoutInflater.rInflate(LayoutInflater.java:727) 01-08 22:16:05.803: E/AndroidRuntime(432): at android.view.LayoutInflater.inflate(LayoutInflater.java:479) 01-08 22:16:05.803: E/AndroidRuntime(432): at android.view.LayoutInflater.inflate(LayoutInflater.java:391) 01-08 22:16:05.803: E/AndroidRuntime(432): at android.view.LayoutInflater.inflate(LayoutInflater.java:347) 01-08 22:16:05.803: E/AndroidRuntime(432): at com.actionbarsherlock.internal.ActionBarSherlockCompat.generateLayout(ActionBarSherlockCompat.java:1010) 01-08 22:16:05.803: E/AndroidRuntime(432): at com.actionbarsherlock.internal.ActionBarSherlockCompat.installDecor(ActionBarSherlockCompat.java:902) 01-08 22:16:05.803: E/AndroidRuntime(432): at com.actionbarsherlock.internal.ActionBarSherlockCompat.setContentView(ActionBarSherlockCompat.java:855) 01-08 22:16:05.803: E/AndroidRuntime(432): at com.actionbarsherlock.ActionBarSherlock.setContentView(ActionBarSherlock.java:672) 01-08 22:16:05.803: E/AndroidRuntime(432): at com.actionbarsherlock.app.SherlockListActivity.setContentView(SherlockListActivity.java:239) 01-08 22:16:05.803: E/AndroidRuntime(432): at ar.android.app.glarm.gui.GLarmMain.onCreate(GLarmMain.java:117) 01-08 22:16:05.803: E/AndroidRuntime(432): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1048) 01-08 22:16:05.803: E/AndroidRuntime(432): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1700) 01-08 22:16:05.803: E/AndroidRuntime(432): ... 11 more 01-08 22:16:05.803: E/AndroidRuntime(432): Caused by: java.lang.reflect.InvocationTargetException 01-08 22:16:05.803: E/AndroidRuntime(432): at java.lang.reflect.Constructor.constructNative(Native Method) 01-08 22:16:05.803: E/AndroidRuntime(432): at java.lang.reflect.Constructor.newInstance(Constructor.java:417) 01-08 22:16:05.803: E/AndroidRuntime(432): at android.view.LayoutInflater.createView(LayoutInflater.java:576) 01-08 22:16:05.803: E/AndroidRuntime(432): ... 25 more 01-08 22:16:05.803: E/AndroidRuntime(432): Caused by: java.lang.NullPointerException 01-08 22:16:05.803: E/AndroidRuntime(432): at com.actionbarsherlock.internal.widget.ActionBarView$HomeView.setUp(ActionBarView.java:1219) 01-08 22:16:05.803: E/AndroidRuntime(432): at com.actionbarsherlock.internal.widget.ActionBarView.(ActionBarView.java:231) 01-08 22:16:05.803: E/AndroidRuntime(432): ... 28 more 由于我的应用程序直接使用Theme.Sherlock，因此清单中没有任何样式。 我的ABS版本是最后一个4.4.0，我试图在API 11模拟器中运行我的应用程序（API 8导致相同的结果）。 API 18工作正常。
在Eclipse中进行一些调试之后，它看起来以下返回两个空视图（ActionBarView.java）：
@Override protected void onFinishInflate() { mUpView = findViewById(R.id.abs__up); mIconView = (ImageView) findViewById(R.id.abs__home); }
当然后来的电话正在回归NPE。 看起来我的LogCat中也有一些警告：

什么可以成为我的问题？
PS。：我使用Eclipse + Maven并包括android-v4支持19.0.1和NineOldAndroids 2.4.0。
编辑
经过一些其他调试后，它看起来像ActionBarSherlock和R.txt（Maven生成的目标/文件夹）中生成的资源编号不一样。 检查调试器，我有：
R.txt -> int layout abs__action_bar_home 0x7f030000 | Debug -> same R.txt -> int id abs__up 0x7f07000b | Debug -> ox7f04000b R.txt -> int id abs__home 0x7f07000a | Debug -> 0x7f04000a
UPDATE
看起来导入apklib时出现问题… R编译出了问题。 解决方法是删除使abs __ * 1的id不对齐的自定义资源并弄乱编号。 例如，我做了以下事情：
- 我检查了ActionBarSherlock失败的地方，对我来说是在加载资源R.id.abs__up时。
- 我从我的R.java文件中获取了资源编号并记下它（0x7f07XXXX）;
- 我删除了0x7f07XXXX之前的所有资源，清理了项目，重新生成了R.我想将R.id.abs__up对齐到它的apklib编号（0x7f04000b）。 我不得不从我的字符串xml中删除三个文件夹（anim /，xml /，raw /）和三个实际资源。
- 现在R.id.abs__up在我编译的R.java中有正确的数字。
