使用部分搜索字符串搜索联系人

Question

我想搜索android用户的联系人列表，只需输入一个特定号码的3-4位数字。我已经写了下面的方法来做同样的事情，但是只有当我写完整的10位数并且不少于10位数时，这个方法才能起作用。这意味着它只适用于精确的匹配。我想从98965开始.以此类推。但我只在输入完9896511112时才给我匹配。

 public static void getContactDetails(Context context, String number, int type) {
        String[] projection = new String[]{
                ContactsContract.PhoneLookup.DISPLAY_NAME,
                ContactsContract.PhoneLookup._ID,
                ContactsContract.PhoneLookup.LOOKUP_KEY,
                ContactsContract.PhoneLookup.PHOTO_URI,
                ContactsContract.PhoneLookup.NUMBER};
        Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number.trim() + "%"));

        Cursor cursor = context.getContentResolver().query(contactUri, null, null, null, null);

        while (Common.nonNull(cursor) && cursor.moveToNext()) {
            String lookUpKey = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.LOOKUP_KEY));
            String mobileNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.NUMBER));
            Log.e("I am found", "Found " + number);
        }
        cursor.close();
    }

请帮我找出我的错误。

啊终于来了。有一件事救了我的命：

Uri uri = Uri.withAppendedPath(ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI, Uri.encode(partial));

使用"ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI"而不是ContactsContract.PhoneLookup.CONTENT_FILTER_URI，，它将对您有效。

以下是我的完整示例：

public static void getContactDetails(Context context, String number, int type) {
    String[] projection = new String[]{
            ContactsContract.PhoneLookup.DISPLAY_NAME,
            ContactsContract.PhoneLookup._ID,
            ContactsContract.PhoneLookup.LOOKUP_KEY,
            ContactsContract.PhoneLookup.PHOTO_URI,
            ContactsContract.CommonDataKinds.Phone.NUMBER};
    Uri contactUri = Uri.withAppendedPath(ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI, Uri.encode(number.trim()));

    Cursor cursor = context.getContentResolver().query(contactUri, projection, null, null, null);

    while (Common.nonNull(cursor) && cursor.moveToNext()) {
        String lookUpKey = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.LOOKUP_KEY));
        String mobileNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
        String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));

        if (mobileNumber.length() > 10) {
            mobileNumber = mobileNumber.substring(mobileNumber.length() - 10);
            if (mobileNumber.startsWith(number)) {
                Log.e("I am found", "I am found " + mobileNumber + displayName);
            }
        }

    }

    cursor.close();
}
