listactivity

问题 I am trying to make a selection ListActivity, similar to the one used to add shortcuts to the launcher screens. I have rolled my own header and footers, which I would like to be "sticky" at the top and bottom of the view when on screen. In order to do this, I am using a RelativeLayout with the header set to dock to top, footer set to dock to bottom, and the list set to go below the header and above the footer. In terms of the overall layout of the activity, this is rendering as I would expect

问题 I am using a ListActivity which fills from a database. Depending on a the information stored in the record I want to format the row in the listView. For example, I have a boolean coulmn which specifies whether the current entry has been 'marked off' and if so then I want to set the strike-through formatting flag on one of the textViews inside the list row. The way I thought that I could do this was by getting the ListView from the ListActivity and then getting the view that I wanted to change

问题 Please help. As I have stated in the title I am trying to make that individual elements of a row of a List adapter launch different actions depending on what the user click. It "kind of" works but it takes LONG for it to react to user clicks. What is it that I am doing wrong? Thanks in advance, So I tried the following code in @Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); // Get the item that was clicked Cursor

问题 I can show the id, title and borrowed values in a TextView . My problem is that I would like to check the "borrowed" values, and if they are not null , display a simple image. If the value is null , I don't want to display anything. Might work with a ViewBinder , but I don't know how to solve this. private static String[] FROM = { _ID, TITLE, BORROWED }; private static String[] TO = { R.id.id, R.id.title, R.id.borrowed }; private Cursor getMovies() { SQLiteDatabase db = movies

问题 my question is how to access and change the checkBox mode for any item in a listactivity. I have an XML template file with a checkbox and a textview, and these define a row.

问题 I have list activity with custom array adapter and I can't to get context menu when make long press on list item. <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"> <ListView android:id="@+id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </FrameLayout>
