Android心得5.3--从通讯录获取和添加联系人

1．加入读取联系人信息的权限

<uses-permissionandroid:name="android.permission.READ_CONTACTS"/>

content://com.android.contacts/contacts操作的数据是联系人信息Uri

content://com.android.contacts/data/phones联系人电话Uri

content://com.android.contacts/data/emails联系人EmailUri

读取联系人信息

2.部分代码：

Cursorcursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,

null, null, null, null);

while (cursor.moveToNext()) {

String contactId =cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));

String name =cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

Cursor phones =getContentResolver().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));

Log.i("RongActivity", "phoneNumber="+phoneNumber);

}

phones.close();

Cursor emails =getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,

null,

ContactsContract.CommonDataKinds.Email.CONTACT_ID+ " = " + contactId,

null,null);

while (emails.moveToNext()) {

// This would allow you get severalemail addresses

String emailAddress =emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));

Log.i("RongActivity","emailAddress="+ emailAddress);

}

emails.close();

}

cursor.close();
