To solve the problem I changed the colors of my theme as described here to avoid override the original unsplash colors.

I also added this in both themes:

        <item name="android:textColorHint">@android:color/darker_gray</item>
        <item name="android:textColorPrimary">@android:color/black</item>

Here is what I had to do: In your androidManifest

<activity
            tools:replace="theme"
            android:theme="@style/UnsplashActivity"
            android:name="com.unsplash.pickerandroid.photopicker.presentation.UnsplashPickerActivity" />

In your style

<style name="UnsplashActivity" parent="AppTheme.NoActionBar">
        <item name="backgroundTint"> <your_color> </item>
        <item name="android:statusBarColor">@color/status_bar_color</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:windowTranslucentStatus">false</item>
        <item name="android:fitsSystemWindows">true</item>
 </style>

Hope that helps ;)
