Android意向无法正常工作

Question

I developed an app.. it is a numerology app.. where user's firstname, second name and third name is collected and calculated... values from 1 -9 are assigned for each values and when calculating these value for all letters has to be added together and make into a one digit 1 - 9. after that this value is given to textview in another activity and the result is displayed.... my problem is i did the programming .. but when adding .. correct value is not displaying.. i used switch case for giving values for each letter... i gave 0 as default value.. when result is displayed the value is displaying as 0 . if i change it to 1 then 1 is added to the value and that value is isplaying.. please check my code and if ther any mistake pls point it out 4 me... thanks...

Answer 1

you have no key sum10 inside your intent , but only name10 . You should see the String int first TextView and nothing in the second one

Answer 2

May be encoding in eclipse is different that Android? Try to change it to UTF-8 in propreties of project.

I tried such concole code. Your function of value10 works correctly.

public class HelloWorld {
  public static void main(String[] args) {

    HelloWorld hw = new HelloWorld();
   long a = hw.value10('F');
   System.out.println("val: " + a);
  }
  private long value10(char a) 

  {
      // TODO Auto-generated method stub
      switch(a)
      {
         case 'A': 
         return 1;    
         case 'B':
         return 2;
         case 'C':
         return 3;
         case 'D':
         return 4;
         case 'E':
         return 5;
         case 'F':
         return 6;
         case 'G':
         return 7;
         case 'H':
         return 8;
         case 'I':
         return 9;
         case 'J':
         return 1;
         case 'K':
         return 2;
         case 'L':
         return 3;
         case 'M':
         return 4;
         case 'N':
         return 5;
         case 'O':
         return 6;
         case 'P':
         return 7;
         case 'Q':
         return 8;
         case 'R':
         return 9;
         case 'S':
         return 1;          
         case 'T':
         return 2;
         case 'U':
         return 3;
         case 'V':
         return 4;
         case 'W':
         return 5;
         case 'X':
         return 6;
         case 'Y':
         return 7;
         case 'Z':
         return 8;
         default:         
         return 0;


      }


  }
