simplecursoradapter

问题 I'm trying to add a background color for an TextView on my ListView using a SimpleCursorAdapter with ViewBinder , but it doesn't work: listrow.xml: <TextView android:id="@+id/catcolor" android:layout_width="4dp" android:layout_height="match_parent" android:layout_margin="4dp" android:background="#FF0099FF" /> <LinearLayout android:paddingTop="4dp" android:paddingRight="4dp" android:paddingLeft="4dp" android:paddingBottom="2dp"> <TextView android:id="@+id/title" android:text="{title}" android

问题 I am writing an application which is using a SimpleCursorAdapter to display a list of items from my SQLite Database. The application is a list application, which allows the user to create a list of items. There is a field in the database that keeps track of whether the user wants the list item's text crossed out or not. Basically, I want to intercept the point in time where the SimpleCursorAdapter tries to settext() on my crossed_out field, and instead call a function to set the text of

问题 I have a ListView which displays a list of items. When I click on an item, I mark the item as striked in my database table. Then, I update the list using a SimpleCursorAdapter, setViewBinder, setViewValue. I check if the striked column is set for a corresponding item, and then I update the TextView to strike the item. The code is below Cursor c = db.fetchAllNotes(id); startManagingCursor(c); String[] from = new String[] { DatabaseHandler.KEY_LIST }; int[] to = new int[] { R.id.text1 };

问题 I'm trying to set onItemClickListener for my adapter, and it works but now i don't know how to get clicked object ? I have a list with notes and on click I want to start new activity with id of clicked note. private DatabaseHelper dbhelper; SimpleCursorAdapter adapter = null; public OnItemClickListener listener = new OnItemClickListener() { public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub Toast.makeText(getApplicationContext(),

问题 Newbee question: Both snippets below work, either from string array or cursor from SQLite table. Now, how do I get these values from the table into a string array so I can manipulate them, then display them as a lstAdapter? (I can provide the complete source but 14 pages 10 pt. minimal heading footer before lots of comments added). I have tried lots of samples from here and other places. Most generate errors I haven't figured out, rest don't work, so I am missing something. This structure

问题 I have a ListView in AcitivityA that is populated using a custom SimpleCursorAdapter called RecipeAdapter . The adapter holds data from SQLite There is a EditText view at the top of the ListView , that filters the listview as the user searches for a recipe. When a user clicks on a item in the filtered ListView , ActivityB starts. This all works perfectly. However when the user presses the backbutton to resume ActivityB , I get the following error. java.lang.IllegalStateException: trying to

问题 I have an app that uses a ViewPager and Fragments to create tabs. Within my app, I have a chat function. Whenever a chat is received or sent, it is stored in a table of the database. The received chats are coming in on a different thread, and the user's chats are being entered into an EditText window in the Chat fragmenet. I have a class called "LogChat.java" that saves the chats to the database. I have a ListView backed by a SimpleCursorAdapter that is displaying the chats. This ListView is

问题 This problem is discussed in this question Android: Wrong item checked when filtering listview. To summarize the problem, when using a listview with a CursorAdapter and a filter, items selected on a filtered list lose their selection after the filter is removed and instead, items at that position in the unfiltered list get selected. Using the code sample in the linked question above, where should we put the code to mark the checkboxes. I believe it should be in the getView() method of the

问题 I was looking for an alternative to a spinner, since the first item is always selected (which causes me issues), and I found some examples for using an AlertDialog with a list instead. I am having two problems: The list is displaying and is formatted ok, but there are no values in it. I know the query is returning, and the cursor/adapter has the data in it. This may be a symptom of #1 - but when I select a blank row, the Cursor cursor2 = (Cursor) ((AdapterView) dialog).getItemAtPosition(which

问题 Data from Cursor added to ListView with SimpleCursorAdapter shows white text (how to make it black) - see the image Here is the Simple cursor adapter code public void displayWords(Cursor c){ // Creates a new SimpleCursorAdapter SimpleCursorAdapter mCursorAdapter = new SimpleCursorAdapter( getApplicationContext(), // The application's Context object android.R.layout.simple_list_item_1, // A layout in XML for one row in the ListView c, // The result from the query new String[] {DatabaseTable
