Error while converting String to Integer in android

Question

I am trying to convert string value into int but it give me error:

android.content.res.resources$notfoundexception string resource id #0x16 <

I tried parsing like:

       String date = "29-30-2098";
       String[] d = date.split("-");
       int di = Integer.parseInt(d[1]);
       Toast.makeText(MainActivity.this, di, Toast.LENGTH_SHORT).show();

if i give String data type to "di" then it print the correct value. But when i try to parse it to Int it give the error And i also tried by using ValueOf(); but in all methods it give me error. Error:

Answer 1

There are two versions of makeText :

• makeText(Context context, CharSequence text, int duration)
• makeText(Context context, int resId, int duration)

The first one takes a String as the second parameter, and shows the message in the string to the user.

The second one takes a resource id as the second parameter, tries to lookup the resource, and fails because you don't have a resource with that id.

To show the int value to the user, you need to convert it to string first, eg String.valueOf(di) .
