issue : i want auto capitalize first letter of edittext not happening. please !

note : want multiline edittext.

you can use code in activity making upper case sentence . in every sentence first word letter uppercase , new sentence means after dot(.) , space .

for example:  i/p---> hi hello. hi hello       o/p---> hi hello. hi hello 

use code

 edittext assignmentname=(edittext) findviewbyid(r.id.assignmentnameid);      string sassignmentname = assignmentname.gettext().tostring();      char[] assignment=sassignmentname.tochararray();                 char[] assignment1=new char[assignment.length];                 int  count=0;                 for(int i=0;i<=assignment.length-1;i++)                 {                     if(i==0 && character.islowercase(assignment[i]) ) {                         char first = assignment[i];                         char first1 = character.touppercase(first);                         assignment1[count] = first1;                         count++;                     }else if(character.iswhitespace(assignment[i-1]) &&  assignment[i-2]=='.'  && character.islowercase(assignment[i]))                     {                         char first = assignment[i];                         char first1 = character.touppercase(first);                         assignment1[count] = first1;                         count++;                     }                     else {                         assignment1[count]=assignment[i];                         count++;                     }                 }                 string uppercaseassignmentname=string.valueof(assignment1);
