happydude’s answer is the most elegant way to handle this but unfortunately (as pointed out in the comments) the source code for ImageView only accepts an integer (solid colour). Issue 18220 has been around for a couple years addressing this, I’ve posted a workaround there that I’ll summarize here: Extend ImageView and wrap drawableStateChanged() with … Read more
The issue is that adjustViewBounds will not increase the size of the ImageView beyond the natural dimensions of the drawable. It will only shrink the view to maintain aspect ratio; if you provide a 500×500 image instead of a 50×50 image, this should work. If you’re interested in the spot where this behavior is implemented, … Read more
Hi please have a try with this as follows if (regProfile.getDrawable().getConstantState() == getResources().getDrawable( R.drawable.ivpic).getConstantState()) { Toast.makeText(_con, “Image is ivPic”, Toast.LENGTH_LONG).show(); // new RegisterAsyntaskNew().execute(); } else { Toast.makeText(_con, “Image isn’t ivPic”, Toast.LENGTH_LONG).show(); // new RegisterAsyntask().execute(); } please use .getConstantState() to compare visit http://developer.android.com/reference/android/graphics/drawable/Drawable.html http://developer.android.com/reference/android/graphics/drawable/Drawable.ConstantState.html EDIT: .getResources().getDrawable(imageResource) Is deprecated in API21, so I changed Jitesh Upadhyay’s answer. … Read more

I was interested in this SO as I didnt know how to do it neither. So I started looking into it and here is how I did it. I am not a specialist in UI so there may be some stuff useless/wrong in the following XML. From what I said above, I didnt manage to … Read more
If you’re in API 21+ you can do this easily in XML with a selector and tint: <?xml version=”1.0″ encoding=”utf-8″?> <selector xmlns:android=”http://schemas.android.com/apk/res/android”> <item android:state_activated=”true”> <bitmap android:src=”https://stackoverflow.com/questions/19500039/@drawable/ic_settings_grey” android:tint=”@color/primary” /> </item> <item android:drawable=”https://stackoverflow.com/questions/19500039/@drawable/ic_settings_grey”/> </selector>
There is a method for doing that, you can retreive resource IDs by string using Resources.getIdentifier() http://developer.android.com/reference/android/content/res/Resources.html Something like: int resourceId = Activity.getResources().getIdentifier(“testimage”, “drawable”, “your.package.name”);
It’s easier than the other response. There is an xml value alpha that takes double values. android:alpha=”0.0″ thats invisible android:alpha=”0.5″ see-through android:alpha=”1.0″ full visible That’s how it works.
You can create a resource (layer drawable xml) for your ImageView‘s “border” (actually background), and declare in your theme that the ImageView‘s background resource is the drawable xml. If you need this “border” to be changed based on the ImageView‘s state (focused, selected, etc.), then you should create more layer drawables, and put them together … Read more
In your AndroidManifest.xml keep this inside application tag, add largeHeap like this: <application android:allowBackup=”true” android:icon=”@mipmap/ic_launcher” android:label=”@string/app_name” android:largeHeap=”true”/>
