问题 Background: I have an orders table in my database whose data I show in RecyclerView . I do it by using a CursorAdapter in RecyclerView.Adapter . All of this is done in parent activity. Besides this I have a child activity which is responsible for adding new orders to orders table and then coming back to parent activity to show all the orders in RecyclerView including the newly ones just created. New orders are added by starting a child activity in addOrder() . Problem: When I come back from

问题 I want to get last visited URL in chrome and other browser's. I am able to get Last URL in android Native browser. I use following code for this - Cursor cur = getContentResolver().query(Browser.BOOKMARKS_URI, new String[] { Browser.BookmarkColumns.URL }, null, null, BookmarkColumns.DATE + " DESC"); if (cur != null && cur.getCount() > 0) { cur.moveToFirst(); String url = cur.getString(cur .getColumnIndex(Browser.BookmarkColumns.URL)); cur.close(); return url; } else { if (cur != null) { cur

问题 It is possible to import a text file of 6MB directly into my database. However, the text can't be extracted since CursorWindow has a limit of 2MB. (I should have used files, but some users already have this problem and I would need to read the entire text to be able to put it in a file) I used substr (a special SQL function) to only request 1 MB and it worked. However, the following while loop doesn't work after the second iteration (which means that even if I called cursor.close(), the

问题 The application has a SearchView which fetches suggestions from a specific database table. Everything worked without any errors until Android 5.0 appeared. As of then, when the SQLiteQueryBuilder queries the database to fill the Cursor object, the return is empty cursor. Not NULL , but empty. On other platforms, I can output the Cursor 's content via DatabaseUtils.dumpCursorToString(cursorObject) , but on Android 5.0+ the method reports output on null objects Dumping cursor null <<<<< Even

问题 I have MyDBHandler with a getAllDetails method that queries the database using a cursor and returns a list. What I don't know what to do now is how to output this list in a listview in another fragment. I was told to create two XML layouts and a custom adapter but I don't know how to this exactly!

问题 I'm stumped as to what is causing this error, as I have made sure that I am closing my database adapter properly (at least I think I am).

问题 I have an app in which one aspect is for a user to select a contact and send a text to that contact thru the app. The app only works with some contacts and fails on others. More precisely: for the contacts that I entered into my contact book by hand, the Intent.ACTION_PICK has no trouble finding and returning them to the app, i.e. cursor.moveToFirst() is true. But for the contact that were imported by Facebook (my phone is set to sync with Facebook contacts), I get the following android
