Android - 如何使用 URI 共享圖像？

Question

我有圖像 uri，我正在嘗試使用下面的代碼共享它，但它不起作用。

共享意圖已打開，但那里沒有圖像。 請在這件事上給予我幫助

private fun ivShareClickListener(position: Int) {
        var file = File(dataList[position].uri.path)
        val sharingIntent = Intent(Intent.ACTION_SEND)
        //sharingIntent.type = "*/*"
        val apkURI = FileProvider.getUriForFile(
            context, context.applicationContext.packageName + ".provider", file
        )
        sharingIntent.setDataAndType(apkURI, "*/*")
        sharingIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
        startActivity(context, Intent.createChooser(sharingIntent, "Share image using"), null)
    }

Answer 1

private void shareImage() {
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.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(share, "Share Image!"));

}
