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

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 was able to achieve this by defining a drawable  something like blank white shape xml     lt shape xmlns android  http   schemas android com apk res android                android shape  rectangle  gt       lt solid android color   android color white   gt   lt  shape gt    Then when I want to clear the image view I just call    imageView setImage R drawable blank white shape     This works beautifully for me

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

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
