How to get Resource(int) from String - Android

Android, getting resource ID from string?

String res = "R.drawable.image1";

I need to get it's INT id. Please help me!

Solution 1

Use this to get resource id:

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

Solution 2

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.

Solution 3

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

sorry my fault I have updated the answer

This returns R.drawable.image1... You used an id you already had, then found it, then get it back

This does not answer the question of retriving an Id using a string because you hardcode it in findViewById
