java.lang.UnsupportedOperationException: Failed to resolve attribute at index 13: TypedValue{t=0x2/d=0x7f010046 a=-1}

Question

I added an attribute to the android attrs.xml file for different color shades. In the styles.xml file I give these attributes colors, so they are different for each style.

Attrs.xml:

<attr name="lightBackground" format="color" />
<attr name="normalBackground" format="color" />

styles.xml:

<style name="AppThemeNight" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimaryNight</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDarkNight</item>
    <item name="colorAccent">@color/colorAccentNight</item>

    <item name="drawerArrowStyle">@style/DrawerIcon</item>
    <item name="lightBackground">@color/colorPrimaryLightNight</item>
    <item name="normalBackground">@color/colorPrimaryNight</item>
</style>

Inflating a custom spinner layout: spinner_layout_adapter.xml:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/spinnerLayoutAdapter_tv_spinnerText"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_weight="1"
      android:padding="15dp"
      android:text="TextView"
      android:textColor="@android:color/white"
      android:background="?attr/normalBackground"
      android:textSize="16sp"/>

However,

When I change the attribute with a normal color like below, it works. The attribute ?attr/normalBackground doesn't seem to work.

android:background="@color/colorPrimary"

Anyone has an idea what I did wrong?

Answer 1

Where do you define that your "AppThemeNight" is to be used? I set up a small project with your code and defined that "AppThemeNight" is to be used in the manifest and everything worked as expected. When I removed the reference to "AppThemeNight" in the manifest the app errored out with the following error:

Caused by: java.lang.UnsupportedOperationException: Failed to resolve attribute at index 13: TypedValue{t=0x2/d=0x7f0200c9 a=-1}

which is what I think that you are seeing, so I don't think that you are specifying that your theme should be used. If you are, please post that, and we'll make another attempt to resolve the issue. For reference, here is my test manifest that works:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.attributes">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppThemeNight">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
