  • Just set that image in `ImageView` and take a look at [Android and setting alpha for (image) view alpha](http://stackoverflow.com/questions/4931071/android-and-setting-alpha-for-image-view-alpha) – Ravi Feb 22 '17 at 06:45

Set this android:alpha="0.5" attribute to your ImageView.

 <ImageView
        android:id="@+id/e4"
        android:layout_width="200dp"
        android:layout_height="100dp"
        android:background="@color/colorAccent"
        android:alpha="0.5" />

you can set alpha value between 0 to 1 for Transparency in Imageview.

Try using this alpha transparency attribute:

http://developer.android.com/reference/android/view/View.html#attr_android:alpha

android:alpha="0.5"

Will give you 50% alpha transparency to the View.

For ex:

<ImageView
        android:id="@+id/Imgexample"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/example"
        android:alpha="0.5" />

If your purpose is to just display with transparency then, you simply use ImageView's setImageAlpha

imageView.setImageAlpha(int)

Value ranges from 0-255

0 being transparent and 255 being opaque

Try to set transparency on ImageView with setAlpha(float) method.. where 0f is full transprent and 1f is fully opaque.

ImageView myImage = (ImageView) findViewById(R.id.myImage);
myImage.setAlpha(0.5f);
