导航抽屉的自定义动画

Question

I've successfully implemented the Navigation Drawer as explained here Now, I'd like to override the default animation for opening/closing. I'd like to use a custom animation. Is it feasible? If so, how can I do it? Thank you very much

Answer 1

You can call openDrawer(int gravity) on the DrawerLayout to make it open the drawer with an animation.

Example:

// 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);
        }
    }
}
