            setContentView(R.layout.activity_main);
        }
      
        /*____________________________________________________________*/
        /*                                                                                                                       */

        /*____________________________________________________________*/
       
     public void showSimpleToastMessage(View view) {
            Toast.makeText(this, "click on \"Show Simple Toast Message\".", Toast.LENGTH_SHORT).show();
        }
       
    
        /*____________________________________________________________*/
        /*                                                                                                                        */
        /*__Methode will be call when user click on "Show Custom Toast Message"__*/
        /*____________________________________________________________*/
       
    
     public void showCustomToastMessage(View view) {
            
    //create the LayoutInflater object
            LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
          
      //Create custom view object
            View customToastView=inflater.inflate(R.layout.custom_toast_view,null);
          
      //create toast object
            Toast toast=new Toast(this);
          
      //update toast to custom view
            toast.setView(customToastView);
       
         //show toast
