在unity3d中刷新android相機膠卷

Question

我為Android設備制作了一個簡單的應用，該應用使用移動相機拍攝照片並將其保存在內部存儲文件夾/ mnt / sdcard / DCIM / Camerizeman /

照片已正確保存，但是我面臨的問題是我看不到來自手機畫廊的照片。 如果我使用文件管理器或重啟設備，我可以正確看到它們。 我現在是searchig 10天，問題是保存圖像后必須刷新圖庫。

我沒有找到任何可行的解決方案。

我的代碼如下：

RenderTexture renderTex;
Texture2D screenshot;
Texture2D LoadScreenshot;
int width = Screen.width; // for Taking Picture
int height = Screen.height; // for Taking Picture
string fileName;
string myScreenshotLocation;
string screenShotName = "MyImage_AR_" + System.DateTime.Now.ToString("yyyy-MM-dd-HHmmss") + ".png";
public void Snapshot ()
{
StartCoroutine (CaptureScreen ());
}
public IEnumerator CaptureScreen ()
{
yield return null; // Wait till the last possible moment before screen rendering to hide the UI
//GameObject.FindGameObjectWithTag("Snapshoot").SetActive(false);
yield return new WaitForEndOfFrame (); // Wait for screen rendering to complete
if (Screen.orientation == ScreenOrientation.Portrait || Screen.orientation == ScreenOrientation.PortraitUpsideDown) {
mainCamera = Camera.main.GetComponent<Camera> (); // for Taking Picture
renderTex = new RenderTexture (width, height, 24);
mainCamera.targetTexture = renderTex;
RenderTexture.active = renderTex;
mainCamera.Render ();
screenshot = new Texture2D (width, height, TextureFormat.RGB24, false);
screenshot.ReadPixels (new Rect (0, 0, width, height), 0, 0);
screenshot.Apply (); //false
RenderTexture.active = null;
mainCamera.targetTexture = null;
}
if (Screen.orientation == ScreenOrientation.LandscapeLeft || Screen.orientation == ScreenOrientation.LandscapeRight) {
mainCamera = Camera.main.GetComponent<Camera> (); // for Taking Picture
renderTex = new RenderTexture (height, width, 24);
mainCamera.targetTexture = renderTex;
RenderTexture.active = renderTex;
mainCamera.Render ();
screenshot = new Texture2D (height, width, TextureFormat.RGB24, false);
screenshot.ReadPixels (new Rect (0, 0, height, width), 0, 0);
screenshot.Apply (); //false
RenderTexture.active = null;
mainCamera.targetTexture = null;
}
myScreenshotLocation = myFolderLocation + screenShotName;
File.WriteAllBytes (myFolderLocation + screenShotName, screenshot.EncodeToPNG ());
}

請幫忙！

第二個可行的解決方案是：

using (AndroidJavaClass jcUnityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
        using (AndroidJavaObject joActivity = jcUnityPlayer.GetStatic<AndroidJavaObject>("currentActivity"))
        using (AndroidJavaObject joContext = joActivity.Call<AndroidJavaObject>("getApplicationContext"))
        using (AndroidJavaClass jcMediaScannerConnection = new AndroidJavaClass("android.media.MediaScannerConnection"))
        using (AndroidJavaClass jcEnvironment = new AndroidJavaClass("android.os.Environment"))
        using (AndroidJavaObject joExDir = jcEnvironment.CallStatic<AndroidJavaObject>("getExternalStorageDirectory"))
        {
            jcMediaScannerConnection.CallStatic("scanFile", joContext, new string[] { YOURFULL IMAGE PATH}, null, null);
        }

Answer 2

使用MediaScannerConnection 。 您需要將圖像“掃描到”圖庫中。

本機Java代碼類似於：

MediaScannerConnection.scanFile(unityPlayerActivity, new String[]{externalImagePath}, null, null);

可以創建插件AndroidJavaClass.CallStatic Android插件教程 （1/3）基礎 -或使用AndroidJavaClass.CallStatic調用MediaScannerConnection.scanFile 。
