问如何在Android上编程共享活动的动作？

EN

Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Compartir");
sendIntent.putExtra(Intent.EXTRA_TEXT, "Descargar");
startActivity(sendIntent);

private void shareFacebook(){

    shareDialog = new ShareDialog(this);
    ShareLinkContent linkContent = new ShareLinkContent.Builder()
            .setContentTitle("Hello Facebook")
            .setContentDescription(
                    "The 'Hello Facebook' sample  showcases simple Facebook integration")
         .setContentUrl(Uri.parse("http://developers.facebook.com/android"))
            .setImageUrl(...)
            .build();
    shareDialog.show(linkContent);
}
