Display user profile the second time he uses the application
<p>Here's the case, the first time the user uses the application and fills in his important personal data on the edittexts, it automatically should be stored in SQLite db. The second time he uses the application, the details he input should be displayed on edittexts and need not be blank fields. How am I going to do that? </p>

<p>the only thing that I already is this.
for my method to checkvalues:</p>

<pre><code>           private void checkValues(){  

           String f1 = etFname.getText().toString();
     String f2 = etLname.getText().toString(); 
     String f3 = etMname.getText().toString();
     String f4 = etAge.getText().toString(); // int
     String f5 = etWeight.getText().toString(); // int
     String f6 = etHeightFt.getText().toString(); // int
     String f7 = etHeightIn.getText().toString(); // int
     String f8 = rgGender.toString();
     String f9 = spBloodType.toString();
     String f10 = spBodyType.toString();
     String f11 = etDOB.getText().toString();

     if ( ( f11.isEmpty() || f1.isEmpty() || f2.isEmpty() || f3.isEmpty() || 
         f4.isEmpty() || f5.isEmpty() || f6.isEmpty() || f7.isEmpty() ||
         f8.isEmpty() || f9.isEmpty() || f10.isEmpty() || f11.isEmpty() ) ) 
     { 

         viewErrorBlankToast();

     }
        else
        {

            boolean didItWork = true;       

            try{

            AddUser entry = new AddUser(Profile.this);
            entry.open();

            entry.createEntry(f1, f2, f3, Integer.parseInt(f4), 
                    Integer.parseInt(f5), Integer.parseInt(f6), Integer.parseInt(f7), 
                    f8, f9, f10, f11);

            entry.close();
            }
            catch(Exception e){
                didItWork = false;

                // call for viewing custom toast
                viewErrorToast();
            }finally{
                if (didItWork){

                viewProfileSavedToast();
                }
            } // end try-finally statement       

        } // end of if-else statement

} // end checkValues method
