اینم نمونه کدش

Timer timer = new Timer();

timer.schedule(new TimerTask() {
    @Override
    public void run() {
        // Your logic here...
        final int[] imageArray={R.drawable.ic_food,R.drawable.ic_discount,R.drawable.ic_movie,R.drawable.ic_travel};
       // final String[] imageArray={"ic_food","ic_discount","ic_movie","ic_travel"
        


        // When you need to modify a UI element, do so on the UI thread.
        // 'getActivity()' is required as this is being ran from a Fragment.
        getActivity().runOnUiThread(new Runnable() {
            @Override
            public void run() {
                // This code will always run on the UI thread, therefore is safe to modify UI elements.
                //myTextBox.setText("my text");
                if (cur<imageArray.length) {
                    String imageName = String.valueOf(imageArray[cur]);
                    int id = getContext().getResources().getIdentifier(imageName, "drawable", getContext().getPackageName());
                    imageView.setImageResource(id);
                    cur++;
                }else{
                    cur = 0;
                    String imageName = String.valueOf(imageArray[cur]);
                    int id = getContext().getResources().getIdentifier(imageName, "drawable", getContext().getPackageName());
                    imageView.setImageResource(id);
                }
            }
        });
    }
}, 0, 3000); // End of your timer code.

حل شد اینم نمونه کد نهایی ... دوستان میتونن استفاده کنن داخل fragment

imageView = (ImageView) root.findViewById(R.id.imgAnim);
Timer timer = new Timer();
timer.schedule(new TimerTask() {
    @Override
    public void run() {
        // Your logic here...
        final int[] imageArray={R.drawable.ic_food,R.drawable.ic_discount,R.drawable.ic_movie,R.drawable.ic_travel};
        // When you need to modify a UI element, do so on the UI thread.
        // 'getActivity()' is required as this is being ran from a Fragment.
        if (isAdded()) {
            getActivity().runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    // This code will always run on the UI thread, therefore is safe to modify UI elements.
                    //myTextBox.setText("my text");
                    if (cur < imageArray.length) {
                        String imageName = String.valueOf(imageArray[cur]);
                        int id = getResources().getIdentifier(imageName, "drawable", getContext().getPackageName());
                        imageView.setImageResource(id);
                        cur++;
                    } else {
                        cur = 0;
                        String imageName = String.valueOf(imageArray[cur]);
                        int id = getResources().getIdentifier(imageName, "drawable", getContext().getPackageName());
                        imageView.setImageResource(id);
                    }
                }
            });
        }
    }
