与Android意图共享图像

我试图通过这样的分享意图分享图像:

Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);

    sharingIntent.setType("image/png");
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, application.getString(R.string.app_name));
    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT,application.getString(R.string.app_share_message));

    File image = new File(Uri.parse("android.resource://" + C.PROJECT_PATH + "/drawable/" + R.drawable.icon_to_share).toString());
        sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(image));
        shareMe(sharingIntent);

共享意图正确触发,我选择Gmail,所有内容都按预期运行,直到我按下发送。我收到通知“无法显示附件”,并且没有它发送电子邮件...... 为什么呢?

感谢您的时间。

首先,无法保证任何给定的其他应用都能支持android:resource// Uri。您将拥有更高的兼容性,可以在外部存储上共享文件或使用ContentProvider

话虽如此,替换:

File image = new File(Uri.parse("android.resource://" + C.PROJECT_PATH + "/drawable/" + R.drawable.icon_to_share).toString());
    sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(image));

使用:

    sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("android.resource://" + C.PROJECT_PATH + "/drawable/" + R.drawable.icon_to_share);

android:resource://不是File,您可能会通过转换为Uri然后转回File来搞乱Uri

BitmapDrawable bitmapDrawable =(BitmapDrawable)ImageView.getDrawable();             Bitmap bitmap = bitmapDrawable.getBitmap();

        // Save this bitmap to a file.
        File cache = getApplicationContext().getExternalCacheDir();
        File sharefile = new File(cache, "toshare.png");
        Log.d("share file type is", sharefile.getAbsolutePath());
        try {
            FileOutputStream out = new FileOutputStream(sharefile);
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
            out.flush();
            out.close();
        } catch (IOException e) {
            Log.e("ERROR", String.valueOf(e.getMessage()));

        }


        // Now send it out to share
        Intent share = new Intent(android.content.Intent.ACTION_SEND);
        share.setType("image/*");
        share.putExtra(Intent.EXTRA_STREAM,
                Uri.parse("file://" + sharefile));

        startActivity(Intent.createChooser(share,
                "Share Image"));

就我而言,我用过:

Uri imageUri = Uri.parse("android.resource://com.examle.tarea/" + R.drawable.tienda_musica);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);           
intent.setType("image/jpeg");
intent.putExtra(Intent.EXTRA_STREAM, imageUri);         
startActivity(Intent.createChooser(intent, getString(R.string.action_share)));

//打开共享意图选择器(将显示已安装的应用程序,我可以从中共享//图像)

private void shareImage(String imagePath,String quoteByPerson,String quoteToShare)         {

        Intent share = new Intent(Intent.ACTION_SEND);
        share.setType("image/*");
        // String imagePath = Environment.getExternalStorageDirectory() +
        // "/myImage.png";
        File imageFileToShare = new File(imagePath);
        Uri uri = Uri.fromFile(imageFileToShare);
        share.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        share.putExtra(Intent.EXTRA_TEXT, "Quote of the day-:" + "\n" + quoteToShare + "\n" + quoteByPerson);

        share.putExtra(android.content.Intent.EXTRA_TITLE, "Quote of the day-:");

        if (imagePath.contains("android.resource://"))
        {
            Uri imageUri = Uri.parse(imagePath);
            share.putExtra(Intent.EXTRA_STREAM, imageUri);

        } else
        {
            share.putExtra(Intent.EXTRA_STREAM, uri);
        }
        startActivity(Intent.createChooser(share, "Share inspiration via..."));
    }
