Error inflating class fragment

2018-12-31 16:36发布

I get the Error

Unable to start activity ComponentInfo{de.androidbuch.activiti/de.androidbuch.activiti.task.Activity}: android.view.InflateException: Binary XML file line #11: Error inflating class fragment

when I switch via the portrait and the landscape mode. I'm using fragments. My xml is:

 <LinearLayout android:id="@+id/mainLayout"
               android:orientation="horizontal"
               android:layout_width="fill_parent"
               android:layout_height="wrap_content" >

    <ListView android:id="@+id/android:list"
              android:layout_height="wrap_content"
              android:layout_width="fill_parent"/> 

    <fragment android:id="@+id/fragmentDetails"
              android:layout_height="fill_parent"
              android:layout_width="fill_parent"
              class="de.androidbuch.activiti.task.TaskDetailsFragment"/> 
</LinearLayout>

If I switch via landscape and portrait mode everything works fine. But when I click on my fragment (and I can see my fragment) and then switch to the other mode I get the error. Any idea how I can solve it? Found some answers here but none of these helped me out...

I had the same problem. The solution for me was the order of super.onCreate and setContentView within the FragmentActivity

Following order works fine:

    super.onCreate(savedInstanceState);
    setContentView(R.layout.fc_activity_list_profiles);

If you have separate layout files for portrait and landscape modes and are getting an inflation error whenever you change orientation after clicking an item, there is most likely a discrepancy between your layout files.

When you get the error, is it only when you click the item in landscape mode or only in portrait mode or both? Does your TaskDetailsFragment activity use a layout file that could have discrepancies between landscape and portrait modes?

I got the same error, but my issue was that my fragment did not have an id in the xml layout of the parent activity.

As hdemirchian said, make sure to use:

import android.support.v4.app.Fragment;

And also make sure that the Activity that is using the fragment(s) extends FragmentActivity instead of the regular Activity,

import android.support.v4.app.FragmentActivity;

to get the FragmentActivity class.

I was receiving this error for different reasons.

Steps to reproduce:

~> My issue was that I created a brand new blank application.

~> I then generated a custom fragment from the File ~> New File Menu.

~> Proceeded to customize the fragment by adding layouts and buttons etc.

~> Referenced the new custom fragment in the auto generated activity_my.xml that was generated for me when creating the application. Doing this allowed the XML to generate the objects for me.

Heres is the catch when generating the custom fragment via File ~> New File Menu it auto generates an interface function stub and places it at the bottom of the fragment class file.

This means that your MyActivity class must implement this interface. If it does not then the the above error occurs only when referencing the fragment from xml. By removing the reference for the Fragment in the XML completely, and creating the fragment through code in the MyActivity.java class file Logcat generates a more concise error explaining the issue in detail and complaining about the interface. This is demonstrated in the Project Template Activity+Fragment. Although, <~that Project Template does not generate the interface stub.

If your TaskDetailsFragment extending android.app.Fragment, do change in onCreateView().

Return your view which you want to show in the Fragment or convert your Layout to view by using LayoutInflater and return it.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View mainview = inflater.inflate(R.layout.main, null);
    return mainview;
}

Hope this works. :)
