java - 如何共享全屏图像android？

Question

我通过从服务器获取来在 View 寻呼机中显示图像。我没有显示全屏图像。我添加了通过电子邮件或许多其他选项共享图像的功能。

分享图片的代码

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);

但共享的图像不是全屏图像。但我想共享实际尺寸的图像。请帮我解决这个问题。

你已经设置了 cacheOnDisk(true)，所以现在你想通过以下方式从中获取图像:

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