Question

我正在使用Google https://developer.android.com/guide/components/intents-common.html中的示例可以使用以下代码启动联系人浏览器。

    Intent intent = new Intent(Intent.ACTION_PICK);
    intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivityForResult(intent, PHONE_ACTIVITY);
    }

我选择了一个联系人，活动退出并调用我的onActivityResult（）

然而，当我使用示例代码从Intent获取结果时，它会在到达查询的最后一行时抛出非法列异常data1（）

public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
        case (PHONE_ACTIVITY): {
            if (resultCode == Activity.RESULT_OK) {
                Uri contactUri = data.getData();
                String[] projection = new String[]{CommonDataKinds.Phone.NUMBER};
                Cursor cursor = getContentResolver().query(contactUri, projection,
                        null, null, null);
             }}}}

我不知道出了什么问题。数据在Uri中，但我得到以下堆栈转储。

好的，如果有人感兴趣的话，谷歌的例子有一个错误。一般的方法是正确的，你用代码调用联系人，但这再次分解为联系人界面有点复杂和记录不足。我将投影设置为null并像这样解析出数据。

            ContentResolver contentResolver = getContentResolver();
            Cursor cursor = getContentResolver().query(contactUri,
                    null, null, null, null);
            // If the cursor returned is valid, get the phone number
            if (cursor != null && cursor.getCount() > 0) {
                cursor.moveToFirst();
                String contact_id = cursor.getString(cursor
                        .getColumnIndex(ContactsContract.Contacts._ID));
                int numberIndex = cursor
                        .getColumnIndex(CommonDataKinds.Phone.NUMBER);
                int hasPhoneNumber = Integer
                        .parseInt(cursor.getString(cursor
                                .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)));

                if (hasPhoneNumber > 0) {
                    Cursor phoneCursor = contentResolver
                            .query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                                    null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                                    new String[] { contact_id }, null);
                    boolean found = false;
                    while (phoneCursor.moveToNext()) {
                        String phoneNumber = phoneCursor
                                .getString(phoneCursor
                                        .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        int phoneType = phoneCursor.getInt(phoneCursor
                                .getColumnIndex(Phone.TYPE));
                        if (phoneType == Phone.TYPE_MOBILE) {
                            phoneNumber = phoneNumber.replaceAll(
                                    "[^\\d]", "");
                            if (phoneNumber.startsWith("1")) {
                                phoneNumber = phoneNumber.substring(1,
                                        phoneNumber.length());
                            }}}}
