Question

它需要屏幕截图，但不会在图库中显示。屏幕截图保存到android / data / com.company.name / file.name但我想用文件名截图将其直接保存到图库

到目前为止，我的代码是：

public void Capture() 
{
    string filename = System.DateTime.Now.ToString("yyyy-MM-dd_HH-mm-ss");
    Application.CaptureScreenshot(filename + ".jpg");
    Debug.Log("captured screenshot");
}

查找提供的答案here（第二个）。它运作得很好。

这是最终的代码：

import UIKit
class CustomImageView: UIImageView {

override public func layoutSubviews() {
    super.layoutSubviews()
    self.roundUpCorners([.topLeft, .bottomLeft], radius: 8)
}
}
extension UIView {
func roundUpCorners(_ corners: UIRectCorner, radius: CGFloat) {
    let path = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius))
    let mask = CAShapeLayer()
    mask.path = path.cgPath
    self.layer.mask = mask
}
}

你只需致电：

protected const string MEDIA_STORE_IMAGE_MEDIA = "android.provider.MediaStore$Images$Media";
protected static AndroidJavaObject m_Activity;

protected static string SaveImageToGallery(Texture2D a_Texture, string a_Title, string a_Description)
{
    using (AndroidJavaClass mediaClass = new AndroidJavaClass(MEDIA_STORE_IMAGE_MEDIA))
    {
        using (AndroidJavaObject contentResolver = Activity.Call<AndroidJavaObject>("getContentResolver"))
        {
            AndroidJavaObject image = Texture2DToAndroidBitmap(a_Texture);
            return mediaClass.CallStatic<string>("insertImage", contentResolver, image, a_Title, a_Description);
        }
    }
}

protected static AndroidJavaObject Texture2DToAndroidBitmap(Texture2D a_Texture)
{
    byte[] encodedTexture = a_Texture.EncodeToPNG();
    using (AndroidJavaClass bitmapFactory = new AndroidJavaClass("android.graphics.BitmapFactory"))
    {
        return bitmapFactory.CallStatic<AndroidJavaObject>("decodeByteArray", encodedTexture, 0, encodedTexture.Length);
    }
}

protected static AndroidJavaObject Activity
{
    get
    {
        if (m_Activity == null)
        {
            AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            m_Activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
        }
        return m_Activity;
    }
}

修改既然你似乎对Unity很陌生，我建议先学习它。无论如何，这里是你如何调用上面提供的代码：

string path = SaveImageToGallery(picture, "Test Picture", "This is a description.");

只需将这两种方法添加到您的代码中，然后从另一个脚本，Unity按钮或其他任何内容调用public void CaptureScreenshot() { StartCoroutine(CaptureScreenshotCoroutine(Screen.width, Screen.height)); } private IEnumerator CaptureScreenshotCoroutine(int width, int height) { yield return new WaitForEndOfFrame(); Texture2D tex = new Texture2D(width, height); tex.ReadPixels(new Rect(0, 0, width, height), 0, 0); tex.Apply(); yield return tex; string path = SaveImageToGallery(tex, "Name", "Description"); Debug.Log("Picture has been saved at:\n" + path); } ......

希望这有帮助，
