我有一个测试活动，它应该做很简单的任务：膨胀视图，并用ObjectAnimator在屏幕上移动它。ActionBarSherlock和Android的ObjectAnimator上的NineOldAndroids之间的区别<11
如果我使用NineOldAndroids库，它可以与所有设备（OS 2.2+ - OS4.2）完美兼容。但是，如果我将库更改为ActionBarSherlock（它假设内部具有相同的NineOldAndroid库），它适用于OS 3.x及更高版本，但它不适用于2.2和2.3设备。在这种情况下，它无法找到该属性并抛出空指针异常（如下所示）。
任何人都有同样的问题？有没有解决方法，或者我实际上使用了两个库（NineOldAndroids和ActionBarSherlock）来解决问题？
这里是TestsActivity：
public class TestActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
RelativeLayout mainLayout = (RelativeLayout) findViewById(R.id.main_layout);
View testView = getLayoutInflater().inflate(R.layout.object_holder, null);
mainLayout.addView(testView);
AnimatorSet set = new AnimatorSet();
set.playTogether(
ObjectAnimator.ofFloat(testView, "translationX", 100),
ObjectAnimator.ofFloat(testView, "translationY", 100)
);
set.setDuration(0).start();
}
}
（同样的事情发生，如果我改变“translationX”与“×”。）
这里是个例外（它的发生只是如果我使用的库actionBarSherlock在2.2和2.3的设备）：
