imeOptions "actionNext" programmatically - how to jump to next field?

You can use the constants from EditorInfo class for the IME options. like,

editText.setImeOptions(EditorInfo.IME_ACTION_NEXT);

Just suggestion, if you are using

     EditTextSample.setImeOptions(EditorInfo.IME_ACTION_DONE); 

it doesn't work, make sure that your EditText is using a single line.

Eg:

       editTextSample.setSingleLine();

Search for the next focusable field and than invoke requestFocus().

TextView nextField = (TextView)currentField.focusSearch(View.FOCUS_RIGHT);
nextField.requestFocus();
