Thread.sleep(500);

Thread.sleep(700);
Button button2 = (Button) (findViewById(R.id.button2));

Don’t use Thread.sleep to delay. This will sleep the UI thread and hang your app. Try View.postDelayed:

ImageView myimage = (ImageView)findViewById(R.id.imageView1);
myimage.setImageDrawable(getResources().getDrawable(R.drawable.img01));
myImage.postDelayed(new Runnable() {
    public void run() {
        myimage.setImageDrawable(null);
        myImage.postDelayed(new Runnable() {
            public void run() {
                Button button2 = (Button) (findViewById(R.id.button2));
                button2.setEnabled(true);
            }
        }, 700);
    }
}, 500);
