Error inflating class ImageView caused by NumberFormatException

Question

I recently got this weird error from a Android 4.2 device when inflating a Spinner item in the getView() method of its ArrayAdapter:

This is the XML of the item's layout:

<!-- item_autocomplete.xml -->
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="48dp"
    android:gravity="center_vertical"
    android:padding="8dp">

    <TextView
        android:id="@+id/item_autocomplete_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:textColor="@color/primaryColor"/>

    <ImageView
        android:id="@+id/item_autocomplete_img"
        android:layout_width="14dp"
        android:layout_height="14dp"
        android:layout_below="@id/item_autocomplete_title"
        android:padding="2dp"
        android:src="@drawable/ic_location_on_black_18dp"
        android:tint="@android:color/tertiary_text_light"/>

    <TextView
        android:id="@+id/item_autocomplete_subtitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/item_autocomplete_img"
        android:layout_toEndOf="@+id/item_autocomplete_img"
        android:layout_toRightOf="@+id/item_autocomplete_img"
        android:textColor="@android:color/tertiary_text_light"
        android:textSize="12sp"/>

</RelativeLayout>

And this is the line where it crashed:

    // SpinnerAdapter.java
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = View.inflate(getContext(), RESOURCE, null); <-- Crash
        }
        ...
    }

So, what's wrong here? Android Studio does not throw me any warning and the app compiles and runs just fine on all devices I have tested...

Answer 1

ImageView's tint is introduced in Android API 21. If you want to use it below API 21 you can use android.support.v7.widget.AppCompatImageView and if you declare the tint as selector in xml you should replace "android:tint" with "app:tint" in the xml

Here is an example:

<android.support.v7.widget.AppCompatImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/btn_apply"
        app:tint="@color/button_selector" />

Answer 2

The problem is just that android:tint="" is to be assigned a color, not a selector, which @android:color/tertiary_text_light is.

Using directly its value #808080 or through a resource value en colors.xml will work @colors/gray_light.
