i suggest use library afollestad/material-dialogs
before start loading show dialog
materialdialog.builder builder = new materialdialog.builder(this) .title(r.string.title) .content(r.string.content) .positivetext(r.string.agree); materialdialog dialog = builder.build(); dialog.show(); after finising loading data dismis dialog
dialog.dismiss();
