PostDelayed and Handler not working and run with no delay

Question

I have a list of animated gifs in drawable resource folder in my android project. I need these gifs played one by one, wait for seconds, and then play the next gif. but when I run the app, all gifs load very very fast so I can just see the last gif. I used Glide for playing gifs and this is my code

Handler handler1 = new Handler();        

for (int a = 1; a<=lines.size() ;a++) {
    handler1.postDelayed(new Runnable() {

        @Override
        public void run() {
            String resName = "";
            int duration = 0;
            resName = "wo_" + (lines.get(slideIndex).split(",")[0]).toLowerCase().trim().replace(".gif", "");
            duration = Integer.parseInt(lines.get(slideIndex++).split(",")[2].trim());
            int resourceId = getResId(resName, R.drawable.class);//this.getResources().getIdentifier(resName, "drawable", this.getPackageName());

            Glide.with(WorkoutActivity.this).asGif().load(resourceId).into(imageView);
        }
    }, 5000);
}

You can use Timer for this

   // Declare globally
private int position = -1;

/**
 * This timer will call each of the seconds.
 */
Timer mTimer = new Timer();
mTimer.schedule(new TimerTask() {
    @Override
    public void run() {
        // As timer is not a Main/UI thread need to do all UI task on runOnUiThread
        getActivity().runOnUiThread(new Runnable() {
            @Override
            public void run() {
                    // increase your position so new image will show
                position++;
                // check whether position increased to length then set it to 0
                // so it will show images in circuler
                if (position >= imageArray.length)
                    position = 0;
                // Set Image
                MyImageView.setImageResource(imageArray[position]);
            }
        });
    }
}, 0, 5000);
