I am using a linear layout and frame layout  In the linear layout I keep an image as background and in the frame layout I keep an imageView  In that imageView I give an image   Now I want to make the second image  that is in the imageView  transparent  How can I do this

Image alpha sets just opacity to ImageView which makes Image blurry, try adding tint attribute in ImageView

 android:tint="#66000000"

It can also be done programatically :

imageView.setColorFilter(R.color.transparent);

where you need to define transparent color in your colors.xml

<color name="transparent">#66000000</color>

On newer versions of Android  post Android 4 2  Jelly Bean  at least   the setAlpha int value  method is depreciated  Instead  use the setAlpha float value  method that takes a float between 0 and 1 where 0 is complete transparency and 1 is no transparency

Set an id attribute on the ImageView    lt ImageView android id    id myImage    In your code where you wish to hide the image  you ll need the following code   First  you ll need a reference to the ImageView   ImageView myImage    ImageView  findViewById R id myImage     Then  set Visibility to GONE   myImage setVisibility View GONE     If you want to have code elsewhere that makes it visible again  just set it to Visible the same way   myImage setVisibility View VISIBLE     If you mean  fully transparent   the above code works  If you mean  partially transparent   use the following method   int alphaAmount   128     Some value 0-255 where 0 is fully transparent and 255 is fully opaque myImage setAlpha alphaAmount
