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..."));
}
