在android中访问SIM卡联系人
我需要访问手机上的前 10 个 SIM 卡联系人。我使用的代码如下:
public class simcontacts extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Uri uri16 = Uri.parse("content://icc/adn/");
String[]SimContactsName = new String[250];
String[]SimContactsNumber = new String[250];
int count = 0;
ContentResolver cr = getApplicationContext().getContentResolver();
Cursor cur = cr.query(uri16,
null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(
cur.getColumnIndex(ContactsContract.Contacts._ID));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext())
{
String contact = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String number = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
SimContactsName[count]=contact;
SimContactsNumber[count]=number;
count++;
}
pCur.close();
}
}
}
TelephonyManager telMng = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
for (int i=0; i<10;i++)
{
Message=Message+SimContactsNumber[i]+"\n";
}
Toast.makeText(this, Message, Toast.LENGTH_LONG).show();
}
当我在手机(htc野火S)上测试它时,我得到了所有空值。 我还使用手机联系人 uri、ContactsContract.Contacts.CONTENT_URI 对其进行了测试,效果很好。 我如何访问 SIM 卡联系人?我必须使用另一个 uri 吗?
i need to access the first 10 sim card contacts on my phone. the code i used is the following:
public class simcontacts extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Uri uri16 = Uri.parse("content://icc/adn/");
String[]SimContactsName = new String[250];
String[]SimContactsNumber = new String[250];
int count = 0;
ContentResolver cr = getApplicationContext().getContentResolver();
Cursor cur = cr.query(uri16,
null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(
cur.getColumnIndex(ContactsContract.Contacts._ID));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext())
{
String contact = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String number = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
SimContactsName[count]=contact;
SimContactsNumber[count]=number;
count++;
}
pCur.close();
}
}
}
TelephonyManager telMng = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
for (int i=0; i<10;i++)
{
Message=Message+SimContactsNumber[i]+"\n";
}
Toast.makeText(this, Message, Toast.LENGTH_LONG).show();
}
when i tested it on the phone, an htc wildfire S, i got all null values.
i also tested it with the phone contacts uri, ContactsContract.Contacts.CONTENT_URI, and it worked fine.
how can i access SIM contacts? is there another uri i must use?

您的代码与
Uri
完美配合:确保您已在 Android Manifest 中添加 android 权限,例如:
android.permission.READ_CONTACTS
(使用权限)。Your code is working perfectly with the
Uri
:Make sure you have added the android permissions in the Android Manifest, like for example:
android.permission.READ_CONTACTS
(Uses Permission).
