Question

Exception occurs when _trd1 starts.
Why it is giving an exception.
I have an imageView on which i have set an Animation.
Same as i did on _imageCard2 they working both fine…
but when i added a new thread it gives an exception after its completion.

public void AnimFunction() {

    TranslateAnimation animation2 = new TranslateAnimation(0, -50, 0, 0);
    animation2.setDuration(100); // duration in ms
    animation2.setRepeatCount(1);
    animation2.setRepeatMode(Animation.REVERSE);
    animation2.setFillAfter(false);
    _imageView.startAnimation(animation2);

    _imageView.setImageResource(R.drawable.b1fv);

    // Animation

    TranslateAnimation animation = new TranslateAnimation(0, 150, 0, 0);
    animation.setDuration(400); // duration in ms
    animation.setRepeatCount(1);
    animation.setRepeatMode(Animation.REVERSE);
    animation.setFillAfter(false);
    _imageCard2.startAnimation(animation);

    Thread _trd1 = new Thread() {
        public void run() {
            try {
                sleep(2000);
                _imageCard2.setImageResource(R.drawable.sk);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    };
    _trd1.start();

}

Try:

Thread _trd1 = new Thread() {
        public void run() {
            try {
                sleep(2000);
                runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    _imageCard2.setImageResource(R.drawable.sk);
                }
            });

            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    };
