您可以在 DrawerLayout 上调用 openDrawer(intgravity) 来使其以动画方式打开抽屉。

例子：

// 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);
        }
    }
}
