问题 I have a list view that is being populated from an SQLite database using the SimpleCursorAdapter. One of the columns being returned in the cursor is an integer value 0 or 1. In my list view, I would like to display this in a more friendly form (ie. "Yes" or "No") and possibly with different text colors for each. Here is my source: Cursor c = dbHelper.fetchAllItems(); startManagingCursor(c); String[] from = {"deployed", "designation", "serial"}; int[] to = {R.id.deployed, R.id.designation, R

问题 i'm having a problem with a Cursor and a SimpleCursorAdapter. What i want to accomplish: I have a database with 3 fields _id | nickName | somethingelse I want to select all nickNames distinctly and provide them in an AutoCompleteTextView. Problem: When doing the query (see below) i don't select the _id-field. That's why i get an error when trying to create the SimpleCursorAdapter because in the cursor there is no field "_id". But if i select the "_id" in the query, the nickNames in the cursor

CheckedTextView not checked

问题 I want a Multiselected (checked) listview . When I select an item then the green check mark must appear. For this I use CheckedTextViews . The ListView gets the data from the database. I'm using a SimpleCursorAdapter for that. When you click on the button then the selected entries(IDs) will be passed to the next activity. My problem is that the check marks of the CheckedTextView does not appear. But the IDs will be passed to the next activity. What am I doing wrong? How to fix it? selecttest

问题 I want to know what are the differences between CursorAdapter and SimpleCursorAdapter. Based on what criteria someone would choose the one or the other. Your experiences working with them? Thank you 回答1: CursorAdapter is abstract and is to be extended. On the other hand, SimpleCursorAdapter is not abstract. Notice that newView(Context context, Cursor cursor, ViewGroup parent) is abstract in CursorAdapter but implemented in SimpleCursorAdapter. This is because SimpleCursorAdapter has a

OnclickListener for individual elements in a row from a ListActivity using SimpleCursorAdapter to Bind to DB not working properly

由 吃可爱长大的小学妹 提交于 2019-12-06 19:13:25
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 c = (Cursor) this.getListAdapter().getItem(position); // c.moveToNext(); prescription_id = c.getString

swapCursor() slow: “The application may be doing too much work on its main thread.”

问题 I keep seeing "The application may be doing too much work on its main thread." Is this being caused by swapCursor() in my code below? It appears so: if I remove it, the above warning disappears. I still don't understand why it claims to be the main thread that is causing the problem. I have moved the swapCursor() around into various places such as onLoadFinished() and in loadInBackground() but I get the same result. How can I call swapCursor() so that this warning doesn't appear?
