How to set ImageView using the name String of the local resource avoiding conditional mapping of resources

Issue

I want to set an ImageView programatically, passing the name of the local resource drawable as String.

The drawable clearly are int identified in this way

 R.drawable.mydrawable_name

How could I do to solve this problem without map everything in a conditional switch?

I want to avoid something in this form

if(myString.equal"stringname_1"){
   myImageview.setImageResource( R.drawable.stringname_1);
}
else if(myString.equal"stringname_1")....
etc

Solution

You can use getResources().getIdentifier() (http://developer.android.com/reference/android/content/res/Resources.html#getIdentifier(java.lang.String, java.lang.String, java.lang.String)) for this purpose. For your code it would look something like this:

int id = getResources().getIdentifier(myString, "drawable", getPackageName());
Drawable drawable = getResources().getDrawable(id);
myImageview.setImageDrawable(drawable);

The code above assumes you're in an Activity.
