You probably want to set an InputFilter on your EditText object

This page has an example of an InputFilter for numeric values

((EditText)findViewById(R.id.EditText01)).addTextChangedListener(new TextWatcher() 
 {           
public void beforeTextChanged(CharSequence s, int start, int count, int after) 
{             
                    //check here if character is '"' if yes don't allow to right
}          
public void onTextChanged(CharSequence s, int start, int before,  int count) 
{            

}            
@Override        
 public void afterTextChanged(Editable s)
 {             
    // TODO Auto-generated method stub         
 }     
});

May this solve it?
