}
3、全局菜单中某一项被选择 // 一个全局菜单项被选择
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
int position = (int) info.id;
Note note = (Note) subjectlist.getItemAtPosition(position);
NoteEntry entry = note.getNoteEntry();
switch (item.getItemId()) {
case R.id.menu_add_note:// 添加日记
