unable to get the working of this for loop

Please explain how this for loop works:

  Button submit = new Button(this);
submit.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View arg0) {
        for (EditText editText : editTexts) {
            editText.getText().toString();
            // whatever u want to do with the strings
        }
    }

Particularly, what does the for (EditText editText : editTexts) part do?

This is saying for each EditText view within editTexts (an array or collection).

EXAMPLE
If editTexts was an array of editTexts like et1,et2,et3,et4 This loop would start at et1 accomlish all the work in the inner loop then go to et2 and do the same thing over and over until after et4 it will exit the loop.

You should look at the type of 'editTexts'. It seems to be a simple 'foreach' loop in java.
