How do I get characters from EditText?

I want to get the String from an EditText and then read individual characters from it. I've tried the following code:

String PT = pt.getText().toString(); 
int len = PT.length(); 
char chars[] = PT.toCharArray(); 
for(int i=0;i<len;i++)
{ Toast.makeText(encrypt.this,chars[i], 0).show(); }

However I get a Force Close error on this. Where am I going wrong?

I'm quite new to all this!

Here's the LogCat:

Toast.makeText(encrypt.this,String.valueOf(chars[i]), 0).show();

instead of 

Toast.makeText(encrypt.this,chars[i], 0).show();

Change your toast message to 

Toast.makeText(encrypt.this,Character.toString(chars[i]), Toast.LENGTH_SHORT).show();

Here the problem is with Toast message. Toast can not Display charaters. so convert charater to string and display

the chars[i] is integer value. If you look closely in your error log you will see 

android.content.res.Resources$NotFoundException: String resource ID #0x61

(if you pass integer parameter, android will lookup for a resource with this Id)

you can print the character from the string directly:

Toast.makeText(encrypt.this,PT[i], 0).show();

probably the edit text (layout resource)is not available when reading the data from it. Just check whether you are able to get no null value when you do 

EditText edt1 = (EditText)findViewById(R.id.myEditView);

log edt1(either through log, system.out.println);
