引出しレイアウトを実装しました。ナビゲーションビュー項目をクリックすると、タブレイアウトが開きます。 tablayoutはうまくいきますが、問題は、アプリケーションがクラッシュするタブレイアウトの[戻る]ボタンをクリックしたときです。また、タブレイアウトが来たときにナビゲーションドロワーが閉じても、ドロワーがスムーズに閉じることがないので、少し遅れがあることに気付きました。DrawerLayout NavigationView重力で引出線が見つからないLEFT

はonBackPressedでDrawerLayoutのあなたのグローバルに定義された変数（）もメソッドを使用します
以下は私のJavaコードとxmlです。 –
私は答えを与えました。それを参照してください。 –
それはまだ失敗します、私は後ろの電話ボタンを押すと動作しますが、ツールバーの後ろのアイコンを押すとクラッシュします –
