Question

执行以下代码后，我希望通过TextView resultText显示联系人列表。

预期结果：

$name = $_POST['name'];
$surname = $_POST['surname'];

然而，在执行1 Peter 1 234-567-8 2 Sam 1122-334-4 3 Mary 1 357-246-8后它崩溃了。错误日志＆＃34; EXED5＆＃34;没有显示。我已经在Cursor c = cr.query(contacts, projection, null, null, null);中添加了权限：

AndroidManifest.xml

代码：

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

错误日志：

Log.d(TAG, "EXED1");
Uri contacts = Contacts.CONTENT_URI;
Log.d(TAG, "EXED2");
String[] projection = {
        ContactsContract.Contacts._ID,
        ContactsContract.Contacts.DISPLAY_NAME,
        ContactsContract.Contacts.HAS_PHONE_NUMBER
};
Log.d(TAG, "EXED3");
ContentResolver cr = getContentResolver();
Log.d(TAG, "EXED4");
Cursor c = cr.query(contacts, projection, null, null, null);
Log.d(TAG, "EXED5");  //Not displayed in the log but it display "AndroidRuntime: Shutting down VM"

String list = "";
int column;
String idStr, nameStr, phoneStr;
Log.d(TAG, "EXED6");

c.moveToFirst();
do {
    Log.d(TAG, "EXED_7_LOOP1");
    column = c.getColumnIndex(ContactsContract.Contacts._ID);
    idStr = c.getString(column);

    column = c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
    nameStr = c.getString(column);

    list += idStr + " " + nameStr;

    column = c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER);
    if (c.getString(column).equals("1")) {
        Cursor phoneC = cr.query(
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                null,
                ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + idStr,
                null,
                null
        );
        phoneC.moveToFirst();
        phoneStr = phoneC.getString(phoneC.getColumnIndex(
                ContactsContract.CommonDataKinds.Phone.NUMBER
        ));
        list += " " + phoneStr;
    }
} while(c.moveToNext());
c.close();
resultText.setText(list);

如何解决问题？
