Obviously you can use maxLength in xml or InputFilter LengthFilter as answered above  But for me in some cases  it was not enough  I created a class for more flexible settings of EditText  https   github com devapro NumberWatcher It is implementation only for numbers input  but you can change it for any of the types

You can use a InputFilter  that s the way   EditText myEditText    EditText  findViewById R id editText1   InputFilter   filters   new InputFilter 1   filters 0    new InputFilter LengthFilter 10     Filter to 10 characters myEditText  setFilters filters
