android.view.InflateException: Binary XML file line #9: Error inflating class <unknown>

Question

I've been looking into this issue for hours and similar errors that had solutions didn't do the trick.

I'm reusing this XML file for multiple ListViews in different activities (which I'm assuming has something to do with it) but I do not see why it would break. The XML file represents the individual items in the ListView.

Here's the XML:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"

    android:paddingRight="10dp"
    android:paddingTop="5dp" >

    <LinearLayout
        android:id="@+id/post"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="?attr/postBackground"
        android:orientation="horizontal" >

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"

            <LinearLayout
                android:id="@+id/postTop"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"

                <TextView
                    android:id="@+id/author"
                    style="?attr/postButton"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_alignParentLeft="true"
                    android:textSize="12sp" />

                <!-- Comments -->

                <TextView
                    android:id="@+id/comments"

            </RelativeLayout>
        </LinearLayout>
    </LinearLayout>

</FrameLayout>

And here's the Java (error occurs on convertView = (FrameLayout) FrameLayout.inflate(mContext, R.layout.column_post, null);) :

Thanks in advance.

Answer 1

Thanks to @kiruwka, the problem is fixed!

The issue was that I needed to make sure that I was using the same theme across activities.
