android系统ContentProvider——联系人

  就做了个查询、添加联系人的例子，其他系统ContentProvider应该也差不多。

 

//查询联系人
    public void query()
    {
    	//获得ContentResolver实例
        ContentResolver cr = this.getContentResolver();
        
        //定义URI
        Uri uri = ContactsContract.Contacts.CONTENT_URI;
        //定义查询数组
//      String[] projection = {ContactsContract.Contacts.DISPLAY_NAME,ContactsContract.Contacts._COUNT};
        //定义查询条件
//      String selection = ContactsContract.Contacts.DISPLAY_NAME +"=?";
        //定义查询条件参数
//      String[] selectionArgs = {"aaa"};  
        //排序列
        String sortOrder = ContactsContract.Contacts._ID;
        
        //查询获得游标
        Cursor c = cr.query(uri, null, null, null, sortOrder);
        
        //遍历
        for(c.moveToFirst();!c.isAfterLast();c.moveToNext())
        {
        	Log.i("people","**********************************************************");
        	//获得联系人的ID号
        	String contactId = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));
        	Log.i("people", "_ID="+contactId);
        	//获得联系人姓名
        	Log.i("people", "DISPLAY_NAME="+c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)));
        	//查看该联系人有多少个电话号码
        	int phoneCount = c.getInt(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
        	if(phoneCount>0)
        	{
        		Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
        				ContactsContract.CommonDataKinds.Phone.CONTACT_ID+ " = " + contactId, null, null);
        		
        		for(phones.moveToFirst();!phones.isAfterLast();phones.moveToNext())
                {
        			Log.i("people", "NUMBER="+phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
                }

            }
        }
        Log.i("people","----------------------------------------------------------");
    }
    
    //添加联系人，name+tel
    public void insert()
    {
        ContentValues values = new ContentValues();
        Uri rawContactUri = getContentResolver().insert(ContactsContract.RawContacts.CONTENT_URI, values);
        long rawContactId = ContentUris.parseId(rawContactUri);
        
        //插入姓名
        values.clear();
        values.put(ContactsContract.Data.RAW_CONTACT_ID, rawContactId);
        values.put(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE);
        values.put(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME, "sq");
        values.put(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME, "c");
        getContentResolver().insert(ContactsContract.Data.CONTENT_URI, values);

        //插入电话号码
        values.clear();
        values.put(ContactsContract.Contacts.Data.RAW_CONTACT_ID, rawContactId);
        values.put(ContactsContract.Contacts.Data.MIMETYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
        values.put(ContactsContract.CommonDataKinds.Phone.NUMBER, "13989297343");
        values.put(ContactsContract.CommonDataKinds.Phone.TYPE, ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE);
        getContentResolver().insert(ContactsContract.Data.CONTENT_URI, values);
    }
