当我单击项目时没有任何反应，我尝试更改颜色、显示所选元素的数量、显示日志什么也没有发生

我的ViewHolder

class MyViewHolder(view: View) : RecyclerView.ViewHolder(view) {

val name: TextView = view.list_item_name
val phone: TextView = view.list_item_phone

// More code here
fun getItemDetails(): ItemDetailsLookup.ItemDetails<Long> =
    object : ItemDetailsLookup.ItemDetails<Long>() {
        override fun getSelectionKey(): Long? = itemId

        override fun getPosition(): Int = adapterPosition

    }

}

我的物品详情查找

class MuLookup(private val rv: RecyclerView) : ItemDetailsLookup<Long>() {
    override fun getItemDetails(event: MotionEvent): ItemDetails<Long>? {
        val view = rv.findChildViewUnder(event.x, event.y)
        if (view != null) {
            return (rv.getChildViewHolder(view) as MyViewHolder)
                .getItemDetails()
        }
        return null
    }
}

我的适配器 …

由于 mysql 5.7.5 group by 有变化

https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html

如果我做这个查询

$qb = $this->createQueryBuilder('d');
$qb->select('ANY_VALUE(d.id), d.nom, count(d.nom) as lignes');
$qb->groupBy('d.nom');   
$qb->orderBy('d.nom');

我有一个错误

SELECT列表的表达式 #1不在GROUP BY子句中，并且包含非聚合列“ sepultures.d0_.id”，该列在功能上不依赖于 GROUP BY 子句中的列；这与 sql_mode=only_full_group_by 不兼容

正如mysql doc中的解释，这个问题可以用这样的any_value解决

$qb = $this->createQueryBuilder('d');
$qb->select('ANY_VALUE(d.id), d.nom, count(d.nom) as lignes');
$qb->groupBy('d.nom');   
$qb->orderBy('d.nom');

但是学说不承认这个功能

[2/2] QueryException: [Syntax Error] line 0, col 7: Error: 预期已知函数，得到“ANY_VALUE”

我该如何解决？

我正在尝试从图库中发送照片，但出现错误指示找不到图像

请求甚至不去服务器

在片段中

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (resultCode == Activity.RESULT_OK) {
        when (requestCode) {
            REQUEST_SELECT_IMAGE_IN_ALBUM -> {
                val contentURI = data!!.data
                postServer(contentURI)

            }
        }
    }
}

private fun postServer(contentURI: Uri) {

    val MEDIA_TYPE_IMAGE: MediaType = MediaType.parse("image/*")!!
    val file = File(contentURI.path)
    val requestBody: RequestBody = RequestBody.create(MEDIA_TYPE_IMAGE, file)
    mercrediViewModel.uploadImage(enfant, requestBody)
}

在我的模型中

fun uploadImage(enfant: Enfant, requestBody: RequestBody) {
    viewModelScope.launch {

        val request = mercrediService.uploadImage("****", enfant.id, requestBody)
        request.enqueue(object : Callback<ResponseBody> {
            override fun onFailure(call: …
