listview

问题 I have a very odd problem that I'm looking into. I didn't write the original code, but I am investigate why its crashing now, all of a sudden. After looking at it, I don't see any reason for the crash. Also, it works perfectly in lower OS levels (e.g., Android 6); however, its consistently crashing when run in Android 7 and 8. It was also very difficult to reproduce at first, because the crash only manifests after the 6th indices... Was originally thinking that it might be some corrupted data

问题 So I am using a Grid View inside of a List View and when I run my application I get this weird spacing stuff before the row of my items, between the items, and at the end (can't see in picture), which I want to remove. Here is my XAML. <ListView x:Name="schemaTableListView" Width="600" Height="50" Margin="0,550,0,0" ItemsSource="{Binding phase}"> <ListView.View> <GridView > <GridView.ColumnHeaderContainerStyle> <Style TargetType="{x:Type GridViewColumnHeader}"> <Setter Property="IsEnabled"

问题 I'm not using a ListActivity because I want to extend FragmentActivity. Instead I'm trying to use: ListView lv = (ListView) findViewById(R.id.mainListView); Unfortunately lv is null. In my xml I have: <ListView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mainListView" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" > </ListView> I've also tried using different android id's for the list view such as the one you

问题 I am developing an app on the android platform that gets youtube video search results as a JSON format and puts the title, channel name, and thumbnail url into a listview. I should also add that I am using the jsoup library for android. Pretty much I am connecting to a URL that contains a JSON response and am trying to use values from that response and apply them to a listview. Here is the method. public void initSearch(String searchQuery) { String url = "https://www.googleapis.com/youtube/v3

问题 Overview I am currently working on a theme system for my application allowing Light and Dark themes for users to choose from (similar to visual studio). The entire process is pretty straight forward and this is how I am changing the BackColor property of the ListView control currently (though I have tried a couple inline solutions that failed such as just setting the BackColor of the ListView and ListViewItem ).
