问题 I'm building an UI where I need to show a list of phone contacts in a list view. I'm using ContactsContract.Data and the CursorLoader to load the data and then binding the cursor to a custom adapter (extended off of SimpleCursorAdapter ). The issue here is that I can't figure out how to filter out the SIM contacts; a test phone I have has identical contacts on the phone as well as the SIM, which causes the listview to have duplicate entries. If I remove the SIM, the duplicates go away. How

问题 I wanna launch the Contacts application from my application Activity. I am not able to understand how to do it. Button contact = (Button) findViewById(R.id.contact); contact.setOnClickListener(new View.OnClickListener() { public void onClick(View arg0) { Intent i4 = new Intent(); i4.setAction(Intent.ACTION_VIEW); i4.addCategory(Intent.CATEGORY_DEFAULT); i4.setType("vnd.android.cursor.dir/phone"); startActivity(i4); } }); Error: 回答1: void showContacts() { Intent i = new Intent(); i

问题 I have an app that gets the ContactsContract.Contacts.LOOKUP_KEY of a contact on the device and saves it on the app Db. After reading this page I thought I could use the LOOKUP_KEY to uniquely identify a contact, even when a contact is edited (for example after editing the name of the contact).

Something like this: private void getContacts(){ ContentResolver resolver = getContentResolver(); Cursor cursor = resolver.query(ContactsContract.contacts.CONTENT_URI,null,null,null,null); while(cursor.moveToNext){ //get contact id ..... //get contact name .... } } What do I mean by contact above: A contact according to my understanding is a set of raw_contacts . Example: These are 2

问题 I'm having a problem with extracting phone numbers of some people in my contact list. First I show all the contacts in a listview: String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.CommonDataKinds.Phone.CONTACT_ID, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER }; mCursor = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection, ContactsContract.CommonDataKinds

问题 I am currently working with the Android Contacts content provider and currently can access a contacts full display name without issue using the following code: String[] PROJECTION = new String[] { ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.HAS_PHONE_NUMBER, }; String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC"; String SELECTION = "LOWER(" + ContactsContract.Contacts.DISPLAY_NAME + ")" + " LIKE '" +
