默認情況下，Android打開菜單導航抽屜

Question

我想知道是否默認情況下可以打開“導航菜單”嗎？

我的應用程序基於此菜單，因此如果默認情況下未打開導航菜單，則看來我的應用程序為空。

我的首選是XML。

感謝幫助！

// Delay is in milliseconds
static final int DRAWER_DELAY = 200;

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...
    // Building NavDrawer logic here. Just a method call would be best.
    ...
    new Handler().postDelayed(openDrawerRunnable(), DRAWER_DELAY);
}

private Runnable openDrawerRunnable() {
    return new Runnable() {

        @Override
        public void run() {
            drawerLayout.openDrawer(Gravity.LEFT);
        }
    }
}
