What does connectAs=“endUser” actually do?

由 故事扮演 提交于 2019-12-08 06:40:44
问题 The Worklight documentation refers to an attribute within the element of an adapter's XML file called connectAs="endUser" . It says that this means that: The connection to the back end is created with the user’s identity. Only valid if a user realm has been identified in the security tests for this procedure. However, what does this actually mean in terms of the HTTP connection that is performed from the adapter to the back-end HTTP server? How does it affect, for example, the JSESSIONID? 回答1

Custom ArrayAdapter for a Spinner: drop down view not working properly

由 丶灬走出姿态 提交于 2019-12-08 03:40:28
问题 I created a custom ArrayAdapter for a Spinner . The difference is, that it shows images from an ArrayList of a complex class instead of plain text. It works so far. The Images and the radio buttons are displayed as desired. The problem is, that the drop down view doesn't behave correctly: it doesn't close on a click and only the radio buttons are clickable instead of the whole view. Does anybody has an idea what's wrong? Do I have to implement some kind of listener in the adapter ?? Here's

Non-clickable Listview Item with Visible Divider

由 半世苍凉 提交于 2019-12-07 16:45:56
问题 I would like to disable clicking of a Listview item. One solution is to override areAllItemsEnabled() to always return false, and isEnabled() to return false for a particular position. However, this causes the divider lines around the particular Listview item to disappear. A few people suggested returning true for areAllItemsEnabled() and false for isEnabled() , but this is not working for me. I am hesitant to place a divider line in manually because I would need to add a parent layout to the

问题 All the examples I have seen on the net contain only 1 TextView per item and they load data from an array. I don't understand how do I specify which data goes where. For example my item layout looks like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/receiver" android:layout_width="wrap
