我的主要活动包括:

public class MainActivity extends Activity {

我觉得放了很多代码,但不是因为它错了
非常感谢你的帮助

如果您打算使用ActionBarSherlock,请从一个Sherlock
类继承,例如SherlockActivity
。如果您还打算使用片段,请从SherlockFragmentActivity
继承
引述:
在所有版本的Android上创建使用操作栏的活动时,必须声明活动以扩展以“Sherlock”开头的任何活动类(例如SherlockActivity、SherlockFragmentActivity)
为了使用compability碎片和ABS,您必须扩展SherlockFragmentActivity
public class MainActivity extends SherlockFragmentActivity {
非常感谢。从SherlockActivity扩展之后我失败了,但扩展SherlockFragmentActivity工作得很完美。我不确定您测试的是什么设备,但对于运行<4.0的设备,我建议对片段使用Support library XML小部件,而不是android.Support.v4.app.Fragment的本机片段,而不是
Fragment
@jsimon:如果您使用的是ActionBarSherlock,就像OP一样,您必须从片段类的Sherlock
版本继承,正如OP所做的那样。@commonware甚至在布局XML中?@jsimon:layout XML中的
元素必须引用从片段类的Sherlock
版本继承的类,如果该片段将参与操作栏。ActionBarSherlock可以使用android.support.v4.app.Fragment
类——有关示例,请参见Maps V2中的SupportMapFragment
。但是,如果您想让片段向操作栏添加项目、启动操作模式或以其他方式使用操作栏,您需要从SherlockFragment
、SherlockListFragment
等继承。如果您使用的是ActionBarSherlock。谢谢!从SherlockActivity扩展之后我失败了,但扩展SherlockFragmentActivity工作得很完美。
