Use this to get resource id:

int picId = getResources().getIdentifier(picName, "drawable", getApplicationContext().getPackageName());

If you want to get the integer then simply remove the quotes.

int id = R.drawable.image1; // instead of "R.drawable.image1"

That will give you the number.

View view = findViewById(R.drawable.image1);
int id = view.getId();

This returns `R.drawable.image1`... You used an id you already had, then found it, then get it back – OneCricketeer Jun 02 '16 at 18:05
This does not answer the question of retriving an Id using a string because you hardcode it in findViewById – Alejandro Jul 31 '16 at 18:55
