Handling Clicks / Why Android menu do not show next image when touching icon?

For some reason when touching the icon in the menu to show a next image the code works but the image doesn't show it.

Code:

@Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()){ case R.id.nextImage: imageIndex++; if (imageIndex >= imageResIds.length){ imageIndex = 0; loadImage(); break; } } return super.onOptionsItemSelected(item); }

Your closing bracket for the if block is misplaced. 

loadImage();
break;

should be outside the block. In the video, Ben is not using any bracket because the statement only consists of one line. Some personal preference.

The way your code is now, you're only increasing the imageIndex, but never loading the image corresponding to that index.

Also, it is much easier to read your code if you format it. Just add 3 backticks (```) before your code, and after and the magic will happen. Hope that helps.
