Error inflating class ImageView - android.view.InflateException: Binary XML file line #10: Error inflating class ImageView

Question

I'm designing an app that has a xml file for the list items (list_item.xml), and an adapter for the listView (NewsAdapter.java).

My app encounters this error when running:

My list_item file has an ImageView:

<ImageView
    android:id="@+id/thumbnail"
    android:layout_width="40dp"
    android:layout_height="wrap_content"
    android:baseline="@id/title"
    app:srcCompat="@android:drawable/ic_lock_lock"
    tools:ignore="NotSibling" />

When I delete ImageView from the list_item.xml, The app runs well!

What should I do?!

NewsAdapter.java:

public class NewsAdapter extends ArrayAdapter {
    Context context;
    List<News> newsList;

    public NewsAdapter(@NonNull Context context, @LayoutRes int resource, @NonNull List objects) {
        super(context, resource, objects);
        this.context = context;
        this.newsList = objects;
    }

    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        News current_news = (News) getItem(position);
        View list_view = convertView;
        if(list_view == null) {
            list_view = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
        }

        TextView title = list_view.findViewById(R.id.title);
        TextView publicationDate = list_view.findViewById(R.id.publicationDate);
        TextView publication = list_view.findViewById(R.id.publication);

        title.setText(current_news.getTitle());
        publicationDate.setText(current_news.getPublication_date());
        publication.setText(current_news.getPublication());

        return list_view;
    }
}

list_item.xml:

<ImageView
    android:id="@+id/thumbnail"
    android:layout_width="40dp"
    android:layout_height="wrap_content"
    android:baseline="@id/title"
    app:srcCompat="@android:drawable/ic_lock_lock"
    tools:ignore="NotSibling" />

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="16dp">

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:ellipsize="end"
        android:maxLines="3"
        tools:text="Is technology delivering in schools? Our panel debates" />

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/title"
        android:layout_alignParentLeft="true"
        android:orientation="horizontal">

        <TextView
            android:id="@+id/publicationDate"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            tools:text="27 Nov, 2016" />

        <TextView
            android:id="@+id/pipe_icon"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/separator_icon" />

        <TextView
            android:id="@+id/publication"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ellipsize="end"
            android:maxLines="1"
            tools:text="The Guardian" />
    </LinearLayout>

</RelativeLayout>

Answer 1

while copying the image files in drawable, you will get option to copy in both drawable and drawable-24. Make sure you copy in both and then try running.

Answer 2

As you see in last lines of error:

Caused by: java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x12

seems you entered something that is not a dimension where you must. And as documentation of attribute android:baseline:

The offset of the baseline within this view. May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

But you used a string for value of baseline.

Answer 3

I had the same problem with my application but finally i SOLVED it. Just put your image file in ic_launcher_background.xml file instead of ic_launcher_foreground.xml file.Hope it helps.
