I use the ViewHolder class for smooth scrolling. But there is something weird I have noticed. Items keep repeating when I scroll down the list or gridView when I implement ViewHolder , as it is recommended in Android guides. But when I initialize views out of it, items don't repeat. Tell me how I can make this

问题 I am trying to determine why an asp.net grid view is so horribly slow. The grid view is contained in a custom sub class that adds a custom pager and does some special formatting. Further, the custom grid view is contained in a user control that puts the grid view in an update panel and combines it with an object data source to making the control easy to use. I have traced the slow downs to two problem areas: The first is the size of the rendered html and viewstate. I managed to improve this

问题 I am using the sample ImageAdpater provided in the google documentation to populate a gridview with drawables. What I'm trying to do is populate the gridview with an array of drawables in an xml file. I use TypedArray imgs = getResources().obtainTypedArray(R.array.log_type_icons); to access the array from my main activity, but that doesn't work within the ImageAdapter class. The array: <string-array name="log_type_icons"> <item>@drawable/ic_launcher</item> <item>@drawable/ic_headache</item>

问题 I'm stuck with the following problem. I'm trying to implement a basic GridView paged result set, which connects to an Oracle database. By itself, the GridView, and the paged results, work fine. The problem comes when I try to put it in page layout class that we have at work. We have ClassA, which inherits from Page, and is a corporate standard. Then I have ClassB, which inherits from ClassA and which includes application-specific code. The page that the GridView is on inherits from ClassB.
