Change Image of ImageView programmatically in Android

That happens because you're setting the src of the ImageView instead of the background.

Use this instead:

qImageView.setBackgroundResource(R.drawable.thumbs_down);

Here's a thread that talks about the differences between the two methods.

Use in XML:

android:src="@drawable/image"

Source use:

imageView.setImageDrawable(ContextCompat.getDrawable(activity, R.drawable.your_image));
