Android: Binary XML file line Error inflating class

Question

I've been trying to load a list of records from a database to a screen but there seems to be a problem when the app gets the data and tries to display it on the screen. I read that sometimes this type of error is thrown when displaying large images and such but I have no images and tried some other solutions I've read about. Any input is appreciated!

Here is the xml of the layout Im trying to "inflate".

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    <LinearLayout
        android:layout_width="match_parent"

                android:textColor="@color/colorText"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="left"
                android:layout_marginBottom="5dp"/>

            <TextView

        </LinearLayout>

            <LinearLayout
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:orientation="horizontal"

                <Button
                    android:id="@+id/add"
                    android:layout_width="40dp"
                    android:layout_height="40dp"
                    android:layout_marginRight="5dp"
                    android:background="@android:drawable/ic_menu_add"/>

                <Button

                    android:layout_height="40dp"
                    android:layout_marginRight="5dp"
                    android:background="@android:drawable/ic_menu_edit"/>

                <Button
                    android:id="@+id/delete"
                    android:layout_width="40dp"
                    android:layout_height="40dp"
                    android:background="@android:drawable/ic_menu_delete"/>
            </LinearLayout>
    </LinearLayout>

Since I'm not really sure where the error is happening, I'm not sure what piece of code to post -and I don't want to make this unreadable.

Answer 1

Currenty you are setting ?android:attr/textAppearanceMedium to android:textSize.
You should replace the attribute with android:textAppearance.

Change

android:textSize="?android:attr/textAppearanceMedium" 

TO

android:textAppearance="?android:attr/textAppearanceMedium"

OR

Set direct value to android:textSizelike

android:textSize="10sp"
