解决方法

Intent tweet = new Intent(Intent.ACTION_VIEW);
tweet.setData(Uri.parse("http://twitter.com/?status=" + Uri.encode(message)));//where message is your string message
startActivity(tweet);

要么,

Intent tweet = new Intent(Intent.ACTION_SEND);
tweet.putExtra(Intent.EXTRA_TEXT,"Sample test for Twitter.");
startActivity(Intent.createChooser(share,"Share this via"));

要么,

String tweetUrl = "https://twitter.com/intent/tweet?text=WRITE YOUR MESSAGE HERE &url="
                    + "https://www.google.com";
Uri uri = Uri.parse(tweetUrl);
startActivity(new Intent(Intent.ACTION_VIEW,uri));
