移动此行：

newweight2 = newweight.getText().toString();

从目前的位置到：

   dialogButton.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {

                   newweight2 = newweight.getText().toString();  //<---------------------------

                   Toast.makeText(Activity3.this,"המשקל " + newweight2 + " נקלט בהצלחה", Toast.LENGTH_LONG).show();
                   dialog.dismiss();
                }
