How do you obtain a Drawable object from a resource id in android package?
Drawable d = getResources().getDrawable(android.R.drawable.ic_dialog_email);ImageView image = (ImageView)findViewById(R.id.image);image.setImageDrawable(d);
As of API 21, you should use the getDrawable(int, Theme) method instead of getDrawable(int), as it allows you to fetch a drawable object associated with a particular resource ID for the given screen density/theme. Calling the deprecated getDrawable(int) method is equivalent to calling getDrawable(int, null).
You should use the following code from the support library instead:
ContextCompat.getDrawable(context, android.R.drawable.ic_dialog_email)Using this method is equivalent to calling:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { return resources.getDrawable(id, context.getTheme());} else { return resources.getDrawable(id);}
As of API 21, you could also use:
ResourcesCompat.getDrawable(getResources(), R.drawable.name, null);Instead of ContextCompat.getDrawable(context, android.R.drawable.ic_dialog_email)
