InflateException错误充气类片段 [英] InflateException error inflating class fragment
问题描述
我开始不断有碎片的活动时收到这个错误。
I keep getting that error when starting the activity that has fragment.
这是我的code的概述：
This is the overview of my code:
的首页的活动从开始的开机的屏幕活动
Home activity is started from Splash screen activity
home.xml （每个片段都有50％ layout_weight ）
home.xml (Each fragment has 50% layout_weight)
<LinearLayout>
<fragment android:name="com.example.test.FragmentClass1" ...>
<fragment android:name="com.example.test.FragmentClass2" ...>
</LinearLayout>
fragment1.xml
<LinearLayout>
//some EditTexts and Buttons here
<LinearLayout>
fragment2.xml
<LinearLayout>
<ListView ... />
</LinearLayout>
FragmentClass1.java
public class FragmentClass1 extends Fragment{
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View view = inflater.inflate(R.layout.fragment1, container, false);
return view;
}
}
FragmentClass2.java
public class FragmentClass2 extends ListFragment{
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View view = inflater.inflate(R.layout.fragment2, container, false);
return view;
}
}
Home.java
public class Home extends Activity{
public View onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
//still empty
}
}
错误日志是这样的：

任何解决方案？谢谢
Any solution? Thanks
推荐答案
如果你正在尝试使用片段支持Android包的反向移植，你需要有你的活动从 FragmentActivity （或者其他什么东西，从 FragmentActivity ，如 SherlockFragmentActivity ）。
If you are trying to use the Android Support package's backport of fragments, you need to have your activity inherit from FragmentActivity (or from something else that inherits from FragmentActivity, like SherlockFragmentActivity).
更新
从堆栈跟踪的关键行是：
The key line from your stack trace is:
12-09 20:39:00.317: E/AndroidRuntime(18214): Caused by: java.lang.ClassCastException: com.example.test.Fragment1 cannot be cast to android.app.Fragment
现在，有没有在你提供的源$ C $ C，它被命名为 com.example.test.Fragment1 。如果这真的是你在您的物品有作为 com.example.test.FragmentClass1 ，那么presumably的片段你继承不是 android.app.Fragment 。最有可能的，在这种情况下，它是 android.support.v4.app.Fragment - 从片段类反向移植的。如果是这样的情况下，改变import语句（并在code基其余任何其他缺陷的）。
Now, there is nothing in your supplied source code that is named com.example.test.Fragment1. If this is really what you have in your listings as com.example.test.FragmentClass1, then presumably the Fragment you are inheriting from is not android.app.Fragment. Most likely, in that case, it is android.support.v4.app.Fragment -- the Fragment class from the backport. If this is the case, change the import statement (and any other flawed ones in the rest of your code base).
