Put another ImageView above the image using a FrameLayout and set this as src:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">

<gradient
    android:angle="270"
    android:startColor="#8000"
    android:endColor="#0000"/>

</shape>

Use AppCompatImageView with tint attribute

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <android.support.v7.widget.AppCompatImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:tint="@color/black_transparent"//transparent color 
        android:scaleType="centerCrop"
        android:src="@drawable/background_splash" />
</FrameLayout>

You can use alpha attribute

android:alpha="0.0" thats invisible
android:alpha="0.5" see-through
android:alpha="1.0" full visible
