Android Share Via Dialog

I've seen the "share via" dialogs that are in apps like TFLN (texts from last night). Looks like this: share dialog http://garr.me/wp-content/uploads/2009/12/sharevia.jpg

I am loo开发者_如何学Pythonking to share text. Can someone point me in the right direction? Is this done with intents?

This is indeed done with Intents.

For sharing an image, like in the example picture, it would be something like this:

Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");

share.putExtra(Intent.EXTRA_STREAM,
  Uri.parse("file:///sdcard/DCIM/Camera/myPic.jpg"));

startActivity(Intent.createChooser(share, "Share Image"));

For text you would use something like:

Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, "I'm being sent!!");
startActivity(Intent.createChooser(share, "Share Text"));

I was having issues with the accepted answer. What worked for me was creating a file from the path, then parsing the URI of the file, like:

Uri.fromFile(new File(filePath));

instead of

Uri.parse(filePath)

Just in case anyone is having the same issue.

Yes. You need to provide an Activity with an intent filter that can handle objects of the MIME Type image/jpeg (say, if you wanted to support sharing JPEG images), and and action of presumably ACTION_SEND.

Many of the built-in Android apps are open-source, you can check the manifest file of the Messaging app to see what intent filters it is using.

Update your manifest

<activity android:name=".ui.MyActivity" >
//To receive single image
<intent-filter>
    <action android:name="android.intent.action.SEND" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="image/*" />
</intent-filter>
//To receive multiple images
<intent-filter>
    <action android:name="android.intent.action.SEND_MULTIPLE" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="image/*" />
</intent-filter>

Handle the incoming content

public class MyActivity extends AppCompactActivity {

    void onCreate(Bundle savedInstanceState) {
        // Get intent, action and MIME type
        Intent intent = getIntent();
        String action = intent.getAction();
        String type = intent.getType();

        if (Intent.ACTION_SEND.equals(action) && type != null) {
            if (type.startsWith("image/")) {
                handleSendImage(intent); // Handle single image being sent
            }
        } else if (Intent.ACTION_SEND_MULTIPLE.equals(action) && type != null) {
            if (type.startsWith("image/")) {
                handleSendMultipleImages(intent); // Handle multiple images being sent
            }
        }
    }

    void handleSendImage(Intent intent) {
        Uri imageUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
        if (imageUri != null) {
            // Update UI to reflect image being shared
        }
    }

    void handleSendMultipleImages(Intent intent) {
        ArrayList<Uri> imageUris = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
        if (imageUris != null) {
            // Update UI to reflect multiple images being shared
        }
    }
}
