判斷當前是否在主執行緒：ThreadExecutor.isMainThread()

如果當前不是主執行緒，切換到主執行緒：

ThreadExecutor.getInstance().executeOnUI(new Runnable() {

        @Override

        public void run() {

            finishAllActivity();

        }

    });

常規程式碼編寫：

if (!ThreadExecutor.isMainThread()) {

    ThreadExecutor.getInstance().executeOnUI(new Runnable() {

        @Override

        public void run() {

            finishAllActivity();

        }

    });

    return;

}
