私は自分のタブのビューページを持っています。私は3つのタブを持っています。最初のタブで計算を行いますが、それはまだsharedPreferencesのtinyDbに保存されています。 2番目のタブで別の計算を行い、答えをtinydbに保存します。これらの答えをボタンのクリックに保存します.3番目のタブは、これらの2つの答えに基づいて計算を行うことになっています。私は計算が完璧に動作することを知っていますが、問題はこれです。私は、アプリケーションがタブ1で計算する必要があると私はタブ2に行くと私はタブ3にonCreateViewは3つの呼び出しに取得されないので、私は戻ってくるまで更新されていないタブ3にもう一度クリックすると、onCreateViewが呼び出されます。私は0にsetOffscreenPageLimitを置くようなsomethingsを試みたが、役に立たない方法で私はこれを訂正してください。onCreateViewがタブ用に呼び出されていない
これはタブ1
