I was able to achieve this by defining a drawable (something like blank_white_shape.xml):

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

Then when I want to clear the image view I just call

 imageView.setImage(R.drawable.blank_white_shape);

This works beautifully for me!

I had a similar problem  where I needed to basically remove ImageViews from the screen completely   Some of the answers here led me in the right direction  but ultimately calling setImageDrawable   worked for me    imgView setImageDrawable null      As mentioned in the comment  such usage is documented in the official docs  ImageView setImageDrawable

If none of these solutions are clearing an image you ve already set  especially setImageResource 0  or setImageResources android R color transparent   check to make sure the current image isn t set as background using setBackgroundDrawable      or something similar   Your code will just set the image resource in the foreground to something transparent in front of that background image you ve set and will still show

Hey i know i am extremely late to this answer  but just thought i must share this   The method to call when u reset the image must be the same method that u called while u were setting it   When u want to reset the image source  dennis sheepard answer works fine only if u are originally setting the image in the bitmap using setImageResource    for instance   i had used setImageBitmap   and hence setting setImageResource 0  didn work  instead i used setImageBitmap null

I tried to remove the Image of the ImageView too by using ImageView setImageRessource 0  but it didn t work for me   Luckily I got this message in the logs    Caused by  java lang IllegalStateException  The specified child already has a parent   You must call removeView   on the child s parent first    So let s say  layoutmanager is your instance for the layout  than you need to do that   RelativeLayout layoutManager   new RelativeLayout this   ImageView image   new ImageView this       this line worked for me layoutManager removeView image

It sounds like what you want is a default image to set your ImageView to when it s not displaying a different image   This is how the Contacts application does it   if  photoId    0        viewToUse setImageResource R drawable ic contact list picture     else              here is where they set an actual image

If you use the support library  you get AppCompatImageView instead of ImageView   which supports setImageResource 0  on all devices  so you should be fine with using it the same way as using setImageDrawable null  and setImageBitmap null   Otherwise  it should work fine starting from some Android version  According to the code of Android and according to my tests  I think it should be safe to use setImageResource 0  from Android API 22  5 1   You can see the Android code of API 22 vs API 21  here

I used to do it with the dennis sheppard solution   viewToUse setImageResource 0     it works but it is not documented so it isn t really clear if it effects something else in the view  you can check the ImageView code if you like  i didn t    I think the best solution is   viewToUse setImageResource android R color transparent     I like this solution the most cause there isn t anything tricky in reverting the state and it s also clear what it is doing
