I have an EditText
field with the attribute inputType set to textMultiLine, this breaks a text into several lines, so far so good. I attached a TextWatcher
to the EditText
so I can check for any change. In the method afterTextChanged I want to check when a line of text is broken into 2 lines, but the textMultiLine attribute does not add a new line char, so my question is:
How can I check how many lines of text have been written in an EditText
with the inputType attribute set to textMultiLine if there is not new line character?
No need to use a Runnable
or post to a message queue. Simply call EditText.getLineCount()
in your afterTextChanged()
method:
final EditText editText = /* your EditText here */;
editText.addTextChangedListener(new TextWatcher() {
...
@Override
public void afterTextChanged(Editable editable) {
int numLines = editText.getLineCount();
// your code here
}
});
