Android Kotlin获取通讯录大头像或封面

这几天做个老人桌面，那些系统自带的通讯录，通讯录列表头像太小了，老人看不清。于是自己写一个老人专用通讯录，给联系人设置大头贴，还能语言报名，这样老人就很好找到需要打电话的联系人！

至于通讯录获取头像，网上有很多方法，但是都太乱了！

简介代码

ContentResolver cr = view.getContext().getContentResolver();
Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI,
Long.parseLong(contact.contact_id));
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(cr, uri);
Bitmap photo = BitmapFactory.decodeStream(input);

加载到自己的ImageView

Glide.with(context)
    .load(Uri.parse(item.photo_uri))
    .into(R.id.iv_photo))

怎么获取通讯录数据

val uri = ContactsContract.CommonDataKinds.Contactables.CONTENT_URI
val PHONE_BOOK_LABEL = "phonebook_label";
contactList = ArrayList<ContactBean>()
val cursor = contentResolver.query(
    uri,
    arrayOf(
        ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
        ContactsContract.CommonDataKinds.Phone.NUMBER,
        ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
        ContactsContract.CommonDataKinds.Phone.PHOTO_FILE_ID,
        ContactsContract.CommonDataKinds.Phone.PHOTO_ID,
        ContactsContract.CommonDataKinds.Phone.PHOTO_THUMBNAIL_URI,
        ContactsContract.CommonDataKinds.Phone.PHOTO_URI,
        PHONE_BOOK_LABEL
    ),
    null,
    null,
    ContactsContract.CommonDataKinds.Phone.SORT_KEY_PRIMARY)
if (null != cursor) {
    while (cursor.moveToNext()) {
        val firstChar =
            cursor.getString(cursor.getColumnIndex(PHONE_BOOK_LABEL))
        val contact_id =
            cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID))
        val name =
            cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME))
        val phoneNum =
            cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))
        val photo_id =
            cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_ID))
        val photo_file_id =
            cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_FILE_ID))
        val photo_uri =
            cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI))
        val photo_thumbnail_uri =
           cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_THUMBNAIL_URI))

        val contact = ContactBean(
            firstChar,
            contact_id,
            name,
            phoneNum,
            photo_id,
            photo_file_id,
            photo_uri,
            photo_thumbnail_uri
        )
        contactList!!.add(contact)
    }
    cursor.close()

自定义的通讯录实体类：

data class ContactBean(
    val firstChar: String? = "",
    val contact_id: String? = "",
    val name: String? = "",
    val phoneNum: String? = "",
    val photo_id: String? = "",
    val photo_file_id: String? = "",
    val photo_uri: String? = "",
    val photo_thumbnail_uri: String? = "") {
    override fun toString(): String {
        return "${firstChar},${name},${contact_id},${phoneNum},${photo_id},${photo_file_id},${photo_uri},${photo_thumbnail_uri}\n"    }
}

可惜头条的代码排版太乱了！
