Answer 1

Use alert.setMessage() instead of builder.setMessage(). Call alert.setMessage() and set message of your dialog anytime you want.

Example:

     AlertDialog.Builder dialogBuilder;
     AlertDialog alertDialog;

     @Override
     protected void onCreate(Bundle savedInstanceState)
     {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);

       dialogBuilder = new AlertDialog.Builder(MainActivity.this);
       alertDialog = dialogBuilder.create();
     }


     public void showAlert(int caller) {
       if(alertDialog != null && !alertDialog.isShowing()) {
        switch (caller){
            case 1:
                alertDialog.setMessage("First method call");
                break;
            case 2:
                alertDialog.setMessage("Second method call");
                break;
            case 3:
                alertDialog.setMessage("Third method call");
                break;
            }
            alertDialog.show();
         }
      }
