Android - Error inflating text view

Question

Android - Error inflating text view

Kim*_*hiu 7 android android-layout android-fragments

I know there are a bunch of similar questions on stackoverflow. But none of these solve my problem.

It's not about theme settings nor resource not found. And I didn't load large images in this layout(all of the backgrounds are from drawable xml). All the attributes have accurate values, including namespace declaration. It just throws this exception randomly. Looks like an android bug.

It happens on Nexus 5X, Nexus 6P, HTC_A9u, ASUS_Z012, etc. I'm using API 25, support library 25.0.1, build tools 25.0.2.

It starts reporting this exception after I change to use API 25.

There are 20 similar nodes in the layout with a ScrollView. And a Fragment holds this layout. I initialize it with fragment transaction, then put it in a DrawerLayout.

The layout node:

<ScrollView
    android:id="@+id/mainMenuScrollView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="10dp">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        ...

        <RelativeLayout
            android:id="@+id/aboutHolder"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:paddingTop="7dp"
            android:paddingBottom="7dp"
            android:paddingStart="10dp"
            android:paddingEnd="5dp"
            android:clickable="true"
            android:background="?theme.mainMenuItemBackground"
            android:layout_below="@+id/otherHolder">
            <TextView
                    android:id="@+id/aboutCapital"
                    android:layout_width="30dp"
                    android:layout_height="30dp"
                    android:layout_centerVertical="true"
                    android:background="@drawable/my_background"
                    android:gravity="center"
                    android:textSize="14sp"
                    android:textColor="?theme.titleColor"
                    android:text="A"/>
            <TextView
                    android:id="@+id/aboutName"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_centerVertical="true"
                    android:layout_marginStart="10dp"
                    android:layout_toEndOf="@+id/aboutCapital"
                    android:textStyle="bold"
                    android:textSize="@dimen/menu_item_title"
                    android:textColor="?theme.titleColor"
                    android:text="About"/>
        </RelativeLayout>

        ...

    </RelativeLayout>

</ScrollView>
