get edittext ( multi-line ) text . Now want to know where a character is not the Enter key,
I use \ r \ n can not match , will be how to achieve ? Is not required to match with the ascii value ? Thank you !

should be \ n it

newline and carriage return has a corresponding value in the Ascii code , 10 and 13 , respectively , declare two char variables, taking out value comparison .

No, with

if (input_current == "\n"){}

not return true
