根据号码取得联系人姓名

网上获取的：

 * 根据电话号码取得联系人姓名 *//*public static String getContactNameByPhoneNumber(Context context,String address) {String[] projection = { ContactsContract.PhoneLookup.DISPLAY_NAME,ContactsContract.CommonDataKinds.Phone.NUMBER };// 将自己添加到 msPeers 中Cursor cursor = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,projection, // Which columns to return.ContactsContract.CommonDataKinds.Phone.NUMBER + " = '"+ address + "'", // WHERE clause.null, // WHERE clause value substitutionnull); // Sort order.if (cursor == null) {Log.d(TAG, "getPeople null");return null;}for (int i = 0; i < cursor.getCount(); i++) {cursor.moveToPosition(i);// 取得联系人名字int nameFieldColumnIndex = cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME);String name = cursor.getString(nameFieldColumnIndex);return name;}return null;}/** * 获取所有联系人内容 *  * @param context * @param address * @return */ /*public static String getContacts(Context context) {StringBuilder sb = new StringBuilder();ContentResolver cr = context.getContentResolver();Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null,null, null, null);if (cursor.moveToFirst()) {do {String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));// 第一条不用换行if (sb.length() == 0) {sb.append(name);} else {sb.append("\n" + name);}Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID+ " = " + contactId, null, null);while (phones.moveToNext()) {String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));// 添加Phone的信息sb.append("\t").append(phoneNumber);}phones.close();} while (cursor.moveToNext());}cursor.close();return sb.toString();}

 

这段代码无法查找sim卡联系人的信息！而且cursor没有关闭，导致许多错误。

 

自己改良后的代码如下：

private static final Uri PHONES_WITH_PRESENCE_URI = Data.CONTENT_URI;    private static final String[] CALLER_ID_PROJECTION = new String[] {            Phone._ID, // 0            Phone.NUMBER, // 1            Phone.LABEL, // 2            Phone.DISPLAY_NAME, // 3            Phone.CONTACT_ID, // 4            Phone.CONTACT_PRESENCE, // 5            Phone.CONTACT_STATUS, // 6            Phone.NORMALIZED_NUMBER, // 7            Contacts.SEND_TO_VOICEMAIL    // 8    };    private static final int PHONE_ID_COLUMN = 0;    private static final int PHONE_NUMBER_COLUMN = 1;    private static final int PHONE_LABEL_COLUMN = 2;    private static final int CONTACT_NAME_COLUMN = 3;    private static final int CONTACT_ID_COLUMN = 4;    private static final int CONTACT_PRESENCE_COLUMN = 5;    private static final int CONTACT_STATUS_COLUMN = 6;    private static final int PHONE_NORMALIZED_NUMBER = 7;    private static final int SEND_TO_VOICEMAIL = 8;    private static final String CALLER_ID_SELECTION_EXACT_MATCH = " Data._ID IN "            + " (SELECT DISTINCT lookup.data_id " + " FROM "            + " (SELECT data_id, normalized_number, length(normalized_number) as len "            + " FROM phone_lookup " + " WHERE normalized_number = ?)
