片段错误充气类片段 [英] Fragment Error inflating class fragment
问题描述
我有一些麻烦片段我得到了一个错误,指出:
I have some trouble with fragment I got an error that says:
Binary XML file line #2 Error: inflating class fragment.
Cause by: Java.lan.NullPointerException: name == null
这是我的二进制文件:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<fragment
android:id="@+id/fragment_content"
android:name="com.livetrekker.fragments.WelcomeFragment"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
然后我FragmentActivity:
Then my FragmentActivity:
public class SetupWizard extends FragmentActivity{
public void onCreate(Bundle bundle){
super.onCreate(bundle);
setContentView(R.layout.activity_wizardsetup);
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
WelcomeFragment wf = new WelcomeFragment();
fragmentTransaction.add(R.id.fragment_content, wf);
fragmentTransaction.commit();
}
}
和我的最后片段:
Public class WelcomeFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
return inflater.inflate(R.layout.welcomelivetrekker,container, false);
}
}
我已导入Android.support.v4.app.Fragment到我的两个文件,并检查了在互联网上,但没有解决方案的工作。
I have imported the Android.support.v4.app.Fragment to both of my file and check out on the internet, but none of the solution is working.
推荐答案
您应该activity_wizardsetup.xml看起来是这样的:
Your activity_wizardsetup.xml should look something like this:
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
</android.support.v4.view.ViewPager>
那么你fragment_content.xml看起来应该以这样的效果:
Then your fragment_content.xml should look something to this effect:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/test"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>
我认为,应该修复它......在我的codeI使用的 FragmentPagerAdapter 而非FragmentTransaction或FragmentManager ...但我认为固定XML起来将工作...
I believe that should fix it... in my code i use a FragmentPagerAdapter rather than FragmentTransaction or FragmentManager... but i think fixing the xml up will work...
