showing multiple images in imageviewer through loop

Question

I want to show multiple images in my imageView I want to do this by using a for loop, but my image view only shows the last image.

I have tried Thread.sleep and sleep functions too but they didn't work

for(int i=0;i<=3;i++){
                try {

                    pic = picText.getText().toString();
                    String photoPath = "sdcard/Pictures/" + pic + i + ".jpg";
                    imageView.setImageBitmap(BitmapFactory.decodeFile(photoPath));
                    sleep(1000);
                } catch (Exception ex) {

                }}

I expect to get all the images one after other, the delay is given in sleep() function.

Use Thread.sleep(1000) which pause the execution of current thread for specified time in milliseconds.

I have tried it too, but it works same as sleep() and only puts the delay and displays the image whose path is passed at the end. – hamza Shahid Apr 09 '19 at 17:06
Check whether photo paths are different for each iteration. log the photopath inside the loop. – Goutham Apr 09 '19 at 17:10
all the photos are in the same folder of Pictures and are named like abc0, abc1, abc2, abc3 – hamza Shahid Apr 09 '19 at 17:18

Get all the imagepath in array or ArrayList and then use a handler and timertask

Timer t; Handler handler; Runnable update; handler = new Handler(); update = new Runnable() { @Override public void run() {
            //load photo
        }
    };
    t = new Timer();
           t.schedule(new TimerTask() {
               @Override
               public void run() {
                   handler.post(update);
               }
           }, 0, 5000);

Note if its showing last image, redirect counter to 1st image. Hope this helps
