android-listview

问题 I'm building a small application that I'd like to automatically update when new data arrives. From what I've read of the android documentation, I thought that because I'm using the newer techniques that a ContentObserver would be created in the background for me, and I would just get automatic calls to the Loader. If there's any more information that would be helpful, I'd be glad to add it, or to upload the complete project somewhere. Additionally, I'm targeting KitKat (sdk version 19).

问题 I am pretty new to android. I want to implement a list view. It contains some list items and when they are clicked, they should expand showing more information. But I unable to find a way to do that Here is my activity_main.xml <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <ListView android:id="@+id/listview1" android:layout_width="match_parent

问题 My app has an orange theme all over but the ScrollBar/FastScroll is appearing green. I've tried to search a lot but can't find any way to change this. It just stays the way it is. I found a "android:fastScrollTextColor" property but that changes the color of the B inside the bubble. And I can't find any property to change the color of this bubble or the ScrollBar next to it. In case it makes a difference I'm using the custom PinnedHeaderListView that I got from here to mimic the sticky

问题 I am developing an accessible app. For this purpose it is important that all elements of the interface can obtain the focus correctly, so that they can be read by Talckback.

I want the children of

问题 I am trying to create a layout with a header, a banner below it, and then a couple of ListView under the banner. I want the the complete screen to be scrollable except the header. Now I know that ListView does not scroll within a ScrollView so I have set the height of the ListView big enough to show all the items. The problem is that, even after these changes, I see that the ListView is scrolling independently and the complete screen is not scrollable. ` <include android:id="@+id/logo_header"

问题 I have read a lot of related questions regarding this question. However, none of them has been answered. I am trying to add a ViewPager to each row in the ListView where there are two layouts within the pager. I believe this is doable because of SwipeListView . Now I have implemented it. However, a blank page is showing with a line in the middle. No rows are appearing. Here is my code: MainActivity + ArrayAdapter public class MainActivity extends Activity { ListView list; String[] heros;

问题 I am currently implementing a multi-select ListView for my android app. My aim is to retrieve the selected items from the ArrayAdapter associated with the ListView when clicking the search button. I am currently stumped on how to do this, I have found stuff online such as trying to set a MultiChoiceModeListener , but this does not seem to come up as an option in Eclipse .

问题 I know that this question is probably asked a hundred times so far, but i still haven't manage to solve my problem. I have one activity that's comprised of 2 fragments. One fragment is a form that adds information to the database: **R.layout.fragment_add_server:** <?xml version="1.0" encoding="utf-8"?> ... <LinearLayout android:id="@+id/nameLinear" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginBottom="5dp" android:layout_marginLeft="5dp" >

问题 I have a custom listview which is done with getView. It must be 4 textview and a radiobutton on the right in each row. I saw many examples about this here but couldn't get the idea. Here is my getView function. With this situation i can see the rows but radiobuttons are still checked when i choose another radiobutton.
