createChooser

Question

我正在尝试将图片和文字分享到手机上的不同应用。我创建了一个IntentChooser来选择要与之分享内容的应用，并创建一个Broadcast Receiver来获取用户点击内容的回调。现在问题在于Facebook。我想分享一个标签，但它不会通过Intent.EXTRA_TEXT。我也整合了Facebook SDK。我添加了Broadcast Receiver，以便我可以显示Facebook的ShareDialog来分享图片和Hashtag。但是当用户从createChooser选择Facebook时，它会打开应用程序，然后回拨Broadcast。

如何将HashTag添加到我通过Facebook分享的帖子中？

public void doSocialShare(String title, String text, Bitmap resource){

        Intent sendIntent = new Intent(android.content.Intent.ACTION_SEND);
        sendIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        sendIntent.putExtra(Intent.EXTRA_TEXT, text);
        sendIntent.putExtra(Intent.EXTRA_STREAM, getBitmapFromDrawable(resource));
        sendIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        sendIntent.setType("image/*");

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP_MR1) {
            Log.d("INFORMATION", "The current android version allow us to know what app is chosen by the user.");

            Intent receiverIntent = new Intent(this,ShareBroadcastReceiver.class);
            PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, receiverIntent, PendingIntent.FLAG_CANCEL_CURRENT);
            sendIntent = Intent.createChooser(sendIntent,"Share via...", pendingIntent.getIntentSender());
        }
        startActivity(sendIntent);
}

这是我的广播接收器：

public class ShareBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO: This method is called when the BroadcastReceiver is receiving
        // an Intent broadcast.
        for (String key : intent.getExtras().keySet()) {
            Log.d(getClass().getSimpleName(), " " + intent.getExtras().get(key));
        }
    }
}
