Question

我有一个自定义的相机实现，我想在拍照时拥有自己的声音如何在硬件相机中启用快门声音，我只需要播放我的相机声音，而不是默认的

private async void TakePhotoButtonTapped(object sender, EventArgs e)
{
Android.Hardware.Camera.CameraInfo info = new Android.Hardware.Camera.CameraInfo();
// mCameraFacing is CameraID.
Android.Hardware.Camera.GetCameraInfo(mCameraFacing, info);
if (info.CanDisableShutterSound)
camera.EnableShutterSound(false);
else
camera.EnableShutterSound(true);
Bitmap image = textureView.Bitmap;
using (var imageStream = new MemoryStream())
{
await image.CompressAsync(Bitmap.CompressFormat.Jpeg, 100, imageStream);
image.Recycle();
imageBytes = imageStream.ToArray();
AddImages(imageBytes);
Toast.MakeText(Android.App.Application.Context, _languageCache.Translate("Photo Captured"), ToastLength.Short).Show();
}
await Task.Delay(300);

您可以使用下面的声音设置代码并将其放入您用于拍照的代码中。

参考系统的ShutterClick声音。你也可以用你自己的。

private void SoundSettings()
{
MediaActionSound sound = new MediaActionSound();
AudioManager meng = (AudioManager)Context.GetSystemService(Context.AudioService);
int volume = meng.GetStreamVolume(Android.Media.Stream.Notification);
if (volume != 0)
sound.Play(MediaActionSoundType.ShutterClick);
}
