我有一个扩展 SherlockActivity 的类,因为我在活动中使用了 ActionBarSherlock 操作栏。但是,我还尝试将上下文菜单添加到此活动中的列表视图,该活动在列表视图中的项目被长按时启动。我的声明中有一个错误,onContextItemSelected(MenuItem item)
表明我的覆盖无效,因为没有什么可以覆盖。但是,当我删除覆盖时,永远不会调用该函数。我知道这与 SherlockActivity 从 Activity 继承的方式有关,但我不确定具体情况。也许我错过了进口?在此处查看相关代码:
public class Inbox extends SherlockActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_inbox);
refreshMsgs(this.getCurrentFocus());
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
if (v.getId() == R.id.lstInbox){
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) menuInfo;
String contactName = lstConversation.get(info.position).getContactName();
menu.setHeaderTitle(contactName);
menu.add(Menu.NONE, 0, 0, "View contact");
menu.add(Menu.NONE, 1, 1, "Delete thread");
}
}
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
SmsConversation selectedConvo = lstConversation.get(info.position);
if (item.getItemId() == 0){
//view contact
Intent viewcontactIntent = new Intent();
String contactId = selectedConvo.getContactId();
Uri uriContact = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, contactId);
viewcontactIntent.setData(uriContact);
PendingIntent pViewIntent = PendingIntent.getActivity(getBaseContext(), 1, viewcontactIntent, 0);
try {
pViewIntent.send();
} catch (CanceledException e) {
e.printStackTrace();
}
} else {
//DELETE thread
}
return true;
}
}
