在仿真器中按照預期方向工作，但不在設備上

Question

我差不多完成了一個應用程序，在該應用程序中，我使用底部導航欄在不同的佈局（不包括活動，如果相關）之間切換，以及一些自定義佈局適用於手機和平板電腦的橫向方向。當我在模擬器中運行應用程序時，我的應用程序的行爲與預期相同，但當我導出一個apk在我的設備（本例中爲手機）上測試時，該應用程序根本不會切換到橫向模式。

讓我知道你是否希望我粘貼我認爲相關的部分代碼 - 我不知道從哪裏開始解決這個問題。

編輯：這裏是清單和活動文件：

你可以試試這個

/** 
    * Getting screen orientation and ON rotation if it is OFF 
    */ 
    private void rotationON() { 
     if (Settings.System.getInt(getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 0) == 0) { 
      Settings.System.putInt(getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 1); 
     } 
    } 

    /** 
    * Getting screen orientation and Off rotation if it is ON 
    */ 
    private void rotationOFF() { 
     if (Settings.System.getInt(getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 0) == 1) { 
      Settings.System.putInt(getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 0); 
     } 
    }
