Question

I get an error when a run this code, every time I set a time on sleep method I get an error and its close the application.

im = (ImageView) findViewById(R.id.imag1);

    Thread t = new Thread() {
        public void run() {
            try {
                sleep(5000);

            } catch (InterruptedException e) {
                e.printStackTrace();
            } finally {

                im.setImageResource(R.drawable.primeiro_misterio_gozoso07);
            }
        }
    };
    t.start();

How can I fix it?

Answer 1

You cannot access the ui from a non ui thread, you can accomplish the same using a handler..

new Handler().postDelayed(new Runnable(){
        @Override
        public void run() {
            im.setImageResource(R.drawable.primeiro_misterio_gozoso07);
        }
    }, 5000);
