How to put black transparent on image in android

try this

<FrameLayout 
android:layout_width="match_parent"
android:layout_height="match_parent" >

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/ur_image" />

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/gradient_bg" >
</FrameLayout>

and gradient_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <gradient
        android:angle="90"
        android:centerColor="#59000000"
        android:endColor="@android:color/transparent"
        android:startColor="#000000" />
</shape>

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>
