现在你有这样的：

super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater =getMenuInflater();
inflater.inflate(R.menu.more_tab_menu, menu);

改成这样：

MenuInflater inflater =getMenuInflater();
inflater.inflate(R.menu.more_tab_menu, menu);
return true;

此外，在onOptionsItemSelected：

Also in onOptionsItemSelected:

return true;

也可以使用onCreateOptionsMenu和onOptionsItemSelected。

Also use onCreateOptionsMenu and onOptionsItemSelected.
