如何为 ImageView 创建共享意图？

我正在创建一个照片应用程序，用户从图库中选择图像，并将其显示在应用程序中心的图像视图中。我将如何为 ImageView 创建共享意图？

更新共享意图正在工作，但是，图像无法共享，因为我无法将其保存到我选择的路径。下面是我的代码。有什么帮助吗？

public void taptoshare(View v)
    {  
        View content = findViewById(R.id.myimage);
        content.setDrawingCacheEnabled(true);
            Bitmap bitmap = content.getDrawingCache();
            File file = new File("/DCIM/Camera/image.jpg");
            try 
            {
                file.createNewFile();
                FileOutputStream ostream = new FileOutputStream(file);
                bitmap.compress(CompressFormat.JPEG, 100, ostream);
                ostream.close();
            } 
            catch (Exception e) 
            {
                e.printStackTrace();
            }


        Intent shareIntent = new Intent(Intent.ACTION_SEND);
        Uri phototUri = Uri.parse("/DCIM/Camera/image.jpg");
        shareIntent.setData(phototUri);
        shareIntent.setType("image/*");
        shareIntent.putExtra(Intent.EXTRA_STREAM, phototUri);
        startActivity(Intent.createChooser(shareIntent, "Share Via"));

}

}

I am creating a photo application where the user selects and image from the gallery and it displays in an imageview in the center of the app. How would I go about creating a share intent for the ImageView?

UPDATE
Share intent is working, however, the image can not be shared because I can not save it to the path I have selected. Below is my code. Any help?

public void taptoshare(View v)
    {  
        View content = findViewById(R.id.myimage);
        content.setDrawingCacheEnabled(true);
            Bitmap bitmap = content.getDrawingCache();
            File file = new File("/DCIM/Camera/image.jpg");
            try 
            {
                file.createNewFile();
                FileOutputStream ostream = new FileOutputStream(file);
                bitmap.compress(CompressFormat.JPEG, 100, ostream);
                ostream.close();
            } 
            catch (Exception e) 
            {
                e.printStackTrace();
            }


        Intent shareIntent = new Intent(Intent.ACTION_SEND);
        Uri phototUri = Uri.parse("/DCIM/Camera/image.jpg");
        shareIntent.setData(phototUri);
        shareIntent.setType("image/*");
        shareIntent.putExtra(Intent.EXTRA_STREAM, phototUri);
        startActivity(Intent.createChooser(shareIntent, "Share Via"));

}

}

试试这个

Intent shareIntent = new Intent(Intent.ACTION_SEND);
Uri phototUri = Uri.parse(path);
shareIntent.setData(photootUri);
shareIntent.setType("image/png");
shareIntent.putExtra(Intent.EXTRA_STREAM, photootUri);
getContext().startActivity(Intent.createChooser(shareIntent, "Use this for sharing"));

Try this

Intent shareIntent = new Intent(Intent.ACTION_SEND);
Uri phototUri = Uri.parse(path);
shareIntent.setData(photootUri);
shareIntent.setType("image/png");
shareIntent.putExtra(Intent.EXTRA_STREAM, photootUri);
getContext().startActivity(Intent.createChooser(shareIntent, "Use this for sharing"));
