Add semi-transparent overlay on imageview

Question

How can I add semi-transparent overlay on imageview?

change it to

Answer 1

A simpler solution could be to use a ColorFilter on the ImageView with PorterDuff.Mode.SRC_OVER

ImageView.setColorFilter(ContextCompat.getColor(
        context,
        R.color.black_opacity_200),
        PorterDuff.Mode.SRC_OVER
);

If you want to get rid of the overlay simply clear it

ImageView.clearColorFilter()

Answer 2

for me, the selected answer didn't worked.But I got it using layer-list..All you got to do is to create a filter file(having your topmost color), a layer-drawable file(joining your filtercolor and image) and use this layer-drawable in your image view.
filter.xml

<shape
    android:shape="rectangle" xmlns:android="http://schemas.android.com/apk/res/android">

    <gradient
        android:startColor="#cf64b5f6"
        android:endColor="#cf1E88E5"
        android:angle="270"
        />

</shape>

• layerlist_drawable.xml

  <layer-list
      xmlns:android="http://schemas.android.com/apk/res/android">
      <item android:drawable="@drawable/my_img" />
      <item android:drawable="@drawable/filter" />
  </layer-list>
  

• main_activity.xml :

  <ImageView
      android:layout_width="match_parent"
      android:layout_height="180dp"
      android:scaleType="centerCrop"
      android:src="@drawable/layerlist_drawable"
      />
