如何分享全屏圖片android？

Question

我通過從服務器獲取來在視圖尋呼機中顯示圖像。我沒有顯示全屏圖像。我添加了通過電子郵件或許多其他選項共享圖像的功能。

用於共享圖像的代碼

imageView = (TouchImageView) viewpager.findViewWithTag(viewpager
            .getCurrentItem());
    imageView.setDrawingCacheEnabled(true);
    Bitmap bitmap = imageView.getDrawingCache();
    String path = Images.Media.insertImage(getContentResolver(), bitmap,
            "description", null);
    uri = Uri.parse(path);
    Intent send_report = new Intent(Intent.ACTION_SEND);
    send_report.putExtra(Intent.EXTRA_EMAIL, new String[] { "" });
    send_report.putExtra(Intent.EXTRA_SUBJECT, "Give Me That Picture");
    send_report.putExtra(Intent.EXTRA_STREAM, uri);
    send_report.putExtra(Intent.EXTRA_TEXT, "cool picture");
    send_report.setType("text/plain");
    send_report.setType("image/png");
    startActivityForResult(
    Intent.createChooser(send_report, "Choose an Email client"), 77);

但共享的圖像不是全屏圖像。但我想分享實際尺寸的圖像。請幫我解決這個問題。

UPDATE 視圖尋呼機適配器

        @Override

        }

    }

Answer 1

您已經設置了cacheOnDisk(true) ，所以現在您要通過以下方式從中獲取圖像：

File cachedImage = imageLoader.getDiscCache().get(imageUrl);
if (cachedImage.exists()) {
    /// get your image from file
}

Answer 2

如果您在視圖尋呼機中獲取當前圖像的緩存，那么您將獲得帶有邊距的視圖尋呼機上顯示的視圖。您需要從服務器下載圖像。在視圖尋呼機中獲取當前顯示圖像的URL並下載來自服務器的圖像。這將解決您的問題。
