I have one existing contact, I need to add a work address to that existing contact. I am using the following code, but it's not working. String selectPhone = Data.CONTACT_ID + "=? AND " + Data.MIMETYPE + "='" + ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE + "'" + " AND " + ContactsContract.CommonDataKinds.StructuredPostal.TYPE + "=?"; String[] phoneArgs = new String[] {String.valueOf(ContactId), String.valueOf( ContactsContract.CommonDataKinds.StructuredPostal.TYPE_WORK)}; ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI) .withSelection(selectPhone, phoneArgs)

At the moment I’m using getContentResolver().query()/managedQuery() to get a cursor to retrieve images from the gallery app. Because the APIs I’m using are partly deprecated I wanted to use CursorLoader with LoaderManager. /** * Creates a cursor to access the content defined by the image uri for API * version 11 and newer. * * @return The created cursor. */ @TargetApi(Build.VERSION_CODES.HONEYCOMB) private Cursor createCursorHoneycomb() { String[] projection = { MediaStore.Images.Media.DATA }; Cursor cursor = getContentResolver().query(imageUri, projection, null, null, null); return cursor; }

Is there an easy way to display a ListView in reverse order? I am trying to create a conversation-based app, and would like the most recent entries to be at the bottom of the ListView. I am aware of transcriptMode and stackFromBottom, however my problem is the order of the data. Say I have 100 conversation items, and want to display items 80-100, with 100 being the most recent conversation item. I would like to show 80-100, which implies an ORDER BY id desc LIMIT 20 in my query, which forces the items to be sorted 100 to 80, the opposite of what I need. I currently have some nasty inner query

I'm querying the CallLog content provider and need to detect the column types. In Honeycomb and newer (API Level 11+) you can get a columns preferred data type by calling the method Cursor.getType(int columnIndex) which returns one of the following types: FIELD_TYPE_NULL (0) FIELD_TYPE_INTEGER (1) FIELD_TYPE_FLOAT (2) FIELD_TYPE_STRING (3) FIELD_TYPE_BLOB (4) How can I accomplish this on pre-Honeycomb <11 devices? I've tried the following: for ( int i = 0; i < cursor.getColumnCount(); i++ ) { int columnType = -1; try { cursor.getInt( i ); columnType = Cursor.FIELD_TYPE_INTEGER; } catch (

I'm searching for a way to prevent the user from moving the cursor position anywhere. The cursor should always stay at the end of the current EditText value. In addition to that the user should not be able to select anything in the EditText. Do you have any idea how to realize that in Android using an EditText? To clarify: the user should be able to insert text, but only at the end. I had the same problem. This ended up working for me: public class CustomEditText extends EditText { @Override public void onSelectionChanged(int start, int end) { CharSequence text = getText(); if (text != null) {

How do I use the String[] selectionArgs in SQLiteDatabase.query() ? I wish I could just set it to null , as I have no use for it. I am just trying to load an entire unsorted table from a database into a Cursor . Any suggestions on how to achieve this? selectionArgs replace any question marks in the selection string. for example: String[] args = { "first string", "second@string.com" }; Cursor cursor = db.query("TABLE_NAME", null, "name=? AND email=?", args, null); as for your question - you can use null Yes, you may set all parameters to null except the table name. for example: Cursor cursor =
