Remarks

Listener for apps to implement handling for insertion of content. Content may be both text and non-text (plain/styled text, HTML, images, videos, audio files, etc).

This listener can be attached to different types of UI components using View#setOnReceiveContentListener.

Here is a sample implementation that handles content URIs and delegates the processing for text and everything else to the platform:<br>

// (1) Define the listener
            public class MyReceiver implements OnReceiveContentListener {
                public static final String[] MIME_TYPES = new String[] {"image/*", "video/*"};

                &#64;Override
                public ContentInfo onReceiveContent(View view, ContentInfo payload) {
                    Pair&lt;ContentInfo, ContentInfo&gt; split =
                            ContentInfoCompat.partition(payload, item -&gt; item.getUri() != null);
                    ContentInfo uriContent = split.first;
                    ContentInfo remaining = split.second;
                    if (uriContent != null) {
                        ClipData clip = uriContent.getClip();
                        for (int i = 0; i < clip.getItemCount(); i++) {
                            Uri uri = clip.getItemAt(i).getUri();
                            // ... app-specific logic to handle the URI ...
                        }
                    }
                    // Return anything that we didn't handle ourselves. This preserves the default platform
                    // behavior for text and anything else for which we are not implementing custom handling.
                    return remaining;
                }
            }

            // (2) Register the listener
            public class MyActivity extends Activity {
                &#64;Override
                public void onCreate(Bundle savedInstanceState) {
                    // ...

                    EditText myInput = findViewById(R.id.my_input);
                    myInput.setOnReceiveContentListener(MyReceiver.MIME_TYPES, new MyReceiver());
                }

Properties

Handle	Gets the JNI value of the underlying Android object. (Inherited from IJavaObject)
JniIdentityHashCode	Returns the value of `java.lang.System.identityHashCode()` for the wrapped instance. (Inherited from IJavaPeerable)
JniManagedPeerState	State of the managed peer. (Inherited from IJavaPeerable)
JniPeerMembers	Member access and invocation support. (Inherited from IJavaPeerable)
PeerReference	Returns a JniObjectReference of the wrapped Java object instance. (Inherited from IJavaPeerable)

Methods

Disposed()	Called when the instance has been disposed. (Inherited from IJavaPeerable)
DisposeUnlessReferenced()	If there are no outstanding references to this instance, then calls `Dispose()`; otherwise, does nothing. (Inherited from IJavaPeerable)
Finalized()	Called when the instance has been finalized. (Inherited from IJavaPeerable)
OnReceiveContent(View, ContentInfo)	Receive the given content.
SetJniIdentityHashCode(Int32)	Set the value returned by `JniIdentityHashCode`. (Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)	Set the value returned by `PeerReference`. (Inherited from IJavaPeerable)
UnregisterFromRuntime()	Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable)

Extension Methods

JavaCast<TResult>(IJavaObject)	Performs an Android runtime-checked type conversion.
JavaCast<TResult>(IJavaObject)
GetJniTypeName(IJavaPeerable)
