小编pol*_*sky的帖子

有些用户告诉我有关的异常:

但我无法理解什么是错的.有没有人对这个问题有一些想法？我试图重复那个例外,但我没有做到这一点.这是代码

@Override
public boolean onCreateOptionsMenu(Menu menu) {  
   MenuInflater inflater = getMenuInflater();
   inflater.inflate(R.menu.app_menu, menu);
   return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {  
   switch (item.getItemId()) {
   case R.id.about:
      startActivity(new Intent(this, AboutActivity.class));
      return true;
   case R.id.settings:
      startActivity(new Intent(this, SettingsActivity.class)); …
