按姓名搜索联系人

Question

我正在尝试创建一个自定义联系人应用程序，该应用程序仅显示那些具有联系人号码的联系人。首先，有没有自动化的方法来做到这一点？假设不是，那么我正在尝试按名称搜索联系人，例如罗汉。

这里是代码：-

Cursor photoCursor = getContentResolver().query(
            android.provider.ContactsContract.Contacts.CONTENT_URI,
            new String[] { ContactsContract.Contacts.PHOTO_ID,
                    ContactsContract.Contacts.DISPLAY_NAME },
            ContactsContract.Contacts.DISPLAY_NAME + " = ?",
            new String[]{"Rohan"}, null);
    photoCursor.moveToFirst();
    while (photoCursor.moveToNext()) {
        Log.d("Photo Thumbnail", "" + photoCursor.getString(1));
    }

虽然联系人存在，但我没有收到任何日志，如果我删除 Selection 和 Selection Args，我会在日志中看到 Rohan。我做错了什么？

Answer 1

搜索部分显示名称的简单解决方案。

ContentResolver contentResolver = getCurrentActivity().getContentResolver();

String   whereString = "display_name LIKE ?";
String[] whereParams = new String[]{ "%" + searchText + "%" };

Cursor contactCursor = contentResolver.query(
        ContactsContract.Data.CONTENT_URI,
        null,
        whereString,
        whereParams,
        null );

while( contactCursor.moveToNext() ) {

    int contactId = getIntFromCursor( contactCursor, ContactsContract.Data.CONTACT_ID );

    Log.d( "Contact ID", contactId)

}

contactCursor.close();

我是用下面的代码做到的

Cursor cursor = getContentResolver().query(
            android.provider.ContactsContract.Contacts.CONTENT_URI,
            new String[] { ContactsContract.Contacts.PHOTO_ID,
                    ContactsContract.Contacts.DISPLAY_NAME,
                    ContactsContract.Contacts._ID },
            ContactsContract.Contacts.HAS_PHONE_NUMBER, null,
            ContactsContract.Contacts.DISPLAY_NAME);

这个cursor 提供了所有具有任何电话号码的联系人，然后我将唯一的ID 保存在ArrayList 中，就像这样

cursor.moveToFirst();

    while (cursor.moveToNext()) {
        contactsID.add(cursor.getString(2));
    }

然后在选择联系人时，我使用此查找联系人号码

Cursor cursor = getContentResolver()
                    .query(android.provider.ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                            new String[] {
                                    ContactsContract.CommonDataKinds.Phone.NUMBER,
                                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
                                    ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME },
                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                                    + " = ?",
                            new String[] { contactsID.get(position) }, null);
            contactNumbers = new ArrayList<String>();
            while (cursor.moveToNext()) {
                contactNumbers.add(cursor.getString(0));
                Log.d("number", cursor.getString(0));
            }

试试这个：

    Cursor contactLookupCursor =
            getContentResolver().query(
                    Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,
                            Uri.encode("Rohan")),
                    new String[] {PhoneLookup.DISPLAY_NAME, PhoneLookup.NUMBER},
                    null,
                    null,
                    null);

    try {
        while (contactLookupCursor.moveToNext()) {
            contactName = contactLookupCursor.getString(contactLookupCursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME));
            contactNumber = contactLookupCursor.getString(contactLookupCursor.getColumnIndexOrThrow(PhoneLookup.NUMBER));
        }
    } finally {
        contactLookupCursor.close();
    }

您似乎正在尝试实现一个允许用户选择联系人的屏幕，然后选择该联系人的电话号码。

如果是这种情况，您可以改用电话选择器意图：

Intent intent = Intent(Intent.ACTION_PICK);
intent.setType(CommonDataKinds.Phone.CONTENT_TYPE);
startActivityForResult(intent, REQUEST_SELECT_PHONE_NUMBER);

这将打开本机联系人应用程序，并允许用户选择联系人和电话号码。 然后，您将在您的应用中收到如下结果：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_SELECT_PHONE_NUMBER && resultCode == RESULT_OK) {
        // Get the URI and query the content provider for the phone number
        Uri contactUri = data.getData();
        String[] projection = new String[]{CommonDataKinds.Phone.NUMBER};
        Cursor cursor = getContentResolver().query(contactUri, projection,
                null, null, null);
        // If the cursor returned is valid, get the phone number
        if (cursor != null && cursor.moveToFirst()) {
            int numberIndex = cursor.getColumnIndex(CommonDataKinds.Phone.NUMBER);
            String number = cursor.getString(numberIndex);
            // Do something with the phone number
            ...
        }
    }
}
