推荐答案
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.
