我試圖鎖定我的屏幕，無論用戶在應用程序何時啓動對話框，然後在對話框關閉時將其解鎖。這是我的鎖定和解鎖代碼：試圖在顯示對話框時鎖定屏幕旋轉
// Sets screen rotation as fixed to current rotation setting
private void mLockScreenRotation() {
Log.d("####################", "screen orientation is " + mContext.getResources().getConfiguration().orientation);
// Stop the screen orientation changing during an event
if (mContext.getResources().getConfiguration().orientation == 1)
((Activity) mContext).setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
else ((Activity) mContext).setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
// switch (mContext.getResources().getConfiguration().orientation)
// {
// case Configuration.ORIENTATION_PORTRAIT:
// ((Activity) mContext).setRequestedOrientation(
// ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
// break;
// case Configuration.ORIENTATION_LANDSCAPE:
// ((Activity) mContext).setRequestedOrientation(
// ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
// break;
// }
}
// allow screen rotations again
private void mUnLockScreenRotation() {
this.setRequestedOrientation(
ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
mIsScreenRotationLocked = false;
}我打電話mLockScreenRotation（）當我啓動任何對話，我呼籲mUnlockScreenRotation（）在我的處理程序，並在我的DialogInterface.OnClickListener的。
有時我的屏幕保持鎖定狀態，但它不一致。任何建議或想法爲什麼或如何處理？
在此先感謝您的幫助！
Ammendment：代碼中我鎖我的屏幕：

發佈代碼，您正在調用'mLockScreenRotation'。 – user432209
我已將代碼添加到了我要求的mLockScreenRotation中。 – taraloca
