を更新し、アンドロイドでレイアウトをリロード私はGitHubのからこのライブラリを使用しています：https://github.com/lzyzsd/CircleProgress円の進行状況バー、プログラム
私はMainLayoutにArcProgressを置きます。私はプログレスバーの値を変更しようとしていますが、画面には表示されません。 mArcProgress.getProgress();でチェックすると正しい値が得られますが、バーは画面上で空であり、進捗状況は表示されません。
私が使用してしようとしていた：
mArcProgress.invalidate();
しかしdoesntの仕事。
私が見つけた唯一の方法はしていました：
finish();
startActivity(getIntent());
が、フルスクリーンで起動するので、私は期待できないとして働き、点滅のように思えます。
誰かがこのアクティビティをどのように知っていますか、このビューを変更して、mArcProgress.setProgress(aNumber);を設定したときの変更を確認できるようにしますか？
