Hi All, I'm really new to Android development, so I have one basic question. I have the following code. I want to change the screen(the Activity) via Options menu: Code (Text): @Override public boolean onOptionsItemSelected(MenuItem item) { // TODO Auto-generated method stub switch (item.getItemId()) { case R.id.item01: Intent intentItem1 = new Intent(this, Item1Activity.class); startActivityForResult(intentItem1, 0); //startActivity(intentItem1); return true; default: return super.onOptionsItemSelected(item); } } But the activity doesn't change and the error message I receive while debugging is that "The resource doesn't exist" Any ideas? Thanks in advance.
Your code for changing the activity looks solid. If you receive the error that a resource cannot be found, that means you're accessing a xml resource that just isn't there. In your example, the only line where you access a resource is your Code (Text): case R.id.item01: line. You should check if your menuitem is really spelled that way. Besides, your compiler should tell you exactly where and what is causing the error, just check the logcat output.
