different of setText(CharSequence,TextView.BufferType) and setText(CharSequence)

Question

what is difference between setText(CharSequence, TextView.BufferType) and setText(CharSequence), and when we should use them?

Answer 1

setText (CharSequence text)

Sets the string value of the TextView. whereas

setText (CharSequence text, TextView.BufferType type) 

Sets the text that this TextView is to display and also sets whether it is stored in a styleable/spannable buffer and whether it is editable.

All BufferType options are:

1. TextView.BufferType.EDITABLE
2. TextView.BufferType.NORMAL
3. TextView.BufferType.SPANNABLE

for e.g.

myEditText.setText("This is new text from setText with BufferType EDITABLE.",  TextView.BufferType.EDITABLE);
