Question

如何在无需在屏幕上显示相机的情况下从前置摄像头拍摄照片。我有服务类

$table1 = [PSCustomObject]@{ Name = 'Abc'; Group = 'Bad'; Policy = 'Great'}, [PSCustomObject]@{ Name = 'redi'; Group = 'Good'; Policy = 'MAD'}
$table2 = [PSCustomObject]@{ Name = 'Abc'; Limit = '10'; used = '5'}, [PSCustomObject]@{ Name = 'redi'; Limit = '20'; used = '1'}

$allTables = $table1 + $table2

$allTables | group Name | Foreach {
    $properties = @{}
    $_.Group | Foreach {
        $_.PsObject.Properties | Where Name -ne 'Name' | Foreach {
            $properties +=  @{
                "$($_.Name)" = "$($_.Value)"
            }
        }
    }
    $properties += @{Name = $_.Name}
    New-Object PSObject –Property $properties
}

和主要活动。我想从主要活动打电话。

Group  : Bad
Policy : Great
Name   : Abc
Limit  : 10
used   : 5

Group  : Good
Policy : MAD
Name   : redi
Limit  : 20
used   : 1

当你在后台线程中时，例如服务使用SurfaceTexture而不是SurfaceHolder。如果您正在寻找实施here is a opensource app，我已经实现了背景视频流和UI视频流。
