1.为什么要实现自定义消息
正如我们自己的app，要实现在分享功能，并且分享的类型也不是固定的传统的分享，同时还可以点击跳转，用传统的融云分享格式是满足不了需求，这就用到了融云自定义消息
2. 怎么去实现自定义分享
-
首先我们应该自定义一个消息类继承融云MessageContent这个类，重写其中的encode方法，将json串转换为byte数组，其中shareTittle等都是在需要在分享中使用的字段，这个地方的键值要与IOS统一，否则会产生无法同步现象
@Override public byte[] encode() { JSONObject jsonObject = new JSONObject(); try { jsonObject.put("shareTitle",shareTitle); jsonObject.put("shareDescription",shareDescription); jsonObject.put("shareImageStr",shareImageStr); jsonObject.put("shareId",shareId); jsonObject.put("shareUrl",shareUrl); jsonObject.put("extra",extra); jsonObject.put("shareType",shareType); }catch (JSONException e){ e.printStackTrace(); } try { return jsonObject.toString().getBytes("UTF-8"); }catch (UnsupportedEncodingException e){ e.printStackTrace(); } return null; }-
重写父类的构造器，其中参数是byte[],将相应的byte[] 转换为json字符串，并将json中的数据赋给该类的字段
public ShareMessageContent(byte[] data) { String jsonStr = null; try { jsonStr = new String(data, "UTF-8"); } catch (UnsupportedEncodingException e1) { } try { JSONObject jsonObj = new JSONObject(jsonStr); if(jsonObj.has("shareTitle")) shareTitle = jsonObj.optString("shareTitle"); if(jsonObj.has("shareDescription")) shareDescription = jsonObj.optString("shareDescription"); if(jsonObj.has("shareImageStr")) shareImageStr = jsonObj.optString("shareImageStr"); if(jsonObj.has("shareId")) shareId = jsonObj.optString("shareId"); if(jsonObj.has("shareUrl")) shareUrl = jsonObj.optString("shareUrl"); if(jsonObj.has("extra")) extra = jsonObj.optString("extra"); if(jsonObj.has("shareType")) shareType = jsonObj.optString("shareType"); } catch (JSONException e) { e.printStackTrace(); } }- 建立以parcel为参数的构造器，并重写writeToParcel方法，这里面用到融云的工具类ParcelUtils,这两个方法必须一一对应，否则会使数据错乱
/** * 以下两个方法必须顺序必须一一对应否则会出现数据混乱 * @param in */ public ShareMessageContent(Parcel in){ setShareTitle(ParcelUtils.readFromParcel(in)); //该类为工具了，消息属性 setShareDescription(ParcelUtils.readFromParcel(in)); setShareImageStr(ParcelUtils.readFromParcel(in)); setShareId(ParcelUtils.readFromParcel(in)); setShareUrl(ParcelUtils.readFromParcel(in)); setExtra(ParcelUtils.readFromParcel(in)); setShareType(ParcelUtils.readFromParcel(in)); } /** * 将类的数据写入外部提供的parcel中 * @param dest 对象被写入Parcel * @param flags 对象如何被写入的附加标志 */ @Override public void writeToParcel(Parcel dest, int flags) { ParcelUtils.writeToParcel(dest,getShareTitle()); ParcelUtils.writeToParcel(dest,getShareDescription()); ParcelUtils.writeToParcel(dest,getShareImageStr()); ParcelUtils.writeToParcel(dest,getShareId()); ParcelUtils.writeToParcel(dest,getShareUrl()); ParcelUtils.writeToParcel(dest,getExtra()); ParcelUtils.writeToParcel(dest,getShareType()); }-
实现 Parcelable中的方法Creator方法，同时重写相应的describeContents()方法
/** * 读取接口，目的要从Parcel中构造一个实现了Parcelable的类的实例处理 */ public static final Creator<ShareMessageContent> CREATOR = new Creator<ShareMessageContent>() { @Override public ShareMessageContent createFromParcel(Parcel source) { return new ShareMessageContent(source); } @Override public ShareMessageContent[] newArray(int size) { return new ShareMessageContent[size]; } }; /** * 描述了包含在 Parcelable 对象排列信息中的特殊对象的类型。 * * @return 一个标志位，表明Parcelable对象特殊对象类型集合的排列。 */ public int describeContents() { return 0; }-
在该model上添加注解信息，以便于融云识别，其中注意属性value1必须是唯一不可重复的标识，同时也是应该和ios定义的城一个字段。
@MessageTag(value = "app:custom", flag = MessageTag.ISCOUNTED | MessageTag.ISPERSISTED) public class CustomizeMessage extends MessageContent { ... } -
注册自定义消息，注册在application中进行注册：
RongIM.registerMessageType(CustomizeMessage.class); -
消息展示创建一个消息提供者，继承IContainerProvider.MessageProvider类，实现其中的5个方法newView (),bingView(),getContentSummary(),onItemClick(),onItemLongClick(),代码如下
/** * desc新建一个消息类继承IContainerItemProvider.MessageProvider类，实现对应接口的方法 * 1.注意开头的注解 * 2.注意泛型 */ @ProviderTag(messageContent = ShareMessageContent.class, showReadState = true) public class ShareMessageContentItemProvider extends IContainerItemProvider.MessageProvider<ShareMessageContent> { public ShareMessageContentItemProvider() { } @Override public View newView(Context context, ViewGroup viewGroup) { View view = LayoutInflater.from(context).inflate(R.layout.item_share_message_rongyun, null);

发送，通过初始化model类将，将该model放在Message中的content中，通过RongIM.getInstance().sendMesssage发出去。
//开始发送消息 //进行分享的操作 Gson gson = new Gson(); String s = gson.toJson(shareModel); //将一个model转化为json字符串 byte[] data = s.getBytes(); //将string转换为byte ShareMessageContent shareMessageContent = new ShareMessageContent(data); io.rong.imlib.model.Message message = new io.rong.imlib.model.Message(); message.setContent(shareMessageContent); message.setTargetId(bean.getUid() + ""); message.setConversationType(Conversation.ConversationType.PRIVATE); message.setMessageDirection(io.rong.imlib.model.Message.MessageDirection.SEND); final String inputContent = input_et.getText().toString(); LogUtils.d("---->>", "---->> inputContent == " + input_et.getText().toString()); final String text = TextUtils.isEmpty(inputContent) ? "" : inputContent; number_tv.setVisibility(View.GONE); LogUtils.d("---->>", "---->> text == " + text); RongIM.getInstance().sendMessage(message, text, text, new IRongCallback.ISendMediaMessageCallback() { @Override public void onProgress(io.rong.imlib.model.Message message, int i) { } @Override public void onCanceled(io.rong.imlib.model.Message message) { pop.dismiss(); } @Override public void onAttached(io.rong.imlib.model.Message message) { } @Override public void onSuccess(io.rong.imlib.model.Message message) { if (!TextUtils.isEmpty(text)) { TextMessage txtMsg = TextMessage.obtain(text); io.rong.imlib.model.Message message1 = io.rong.imlib.model.Message.obtain(bean.getUid() + "", Conversation.ConversationType.PRIVATE, txtMsg); RongIM.getInstance().sendMessage(message1, null, null, new IRongCallback.ISendMediaMessageCallback() { @Override public void onProgress(io.rong.imlib.model.Message message, int i) { } @Override public void onCanceled(io.rong.imlib.model.Message message) { } @Override public void onAttached(io.rong.imlib.model.Message message) { } @Override public void onSuccess(io.rong.imlib.model.Message message) { ToastUtil.show(context, "分享成功"); pop.dismiss(); finish(); } @Override public void onError(io.rong.imlib.model.Message message, RongIMClient.ErrorCode errorCode) { pop.dismiss(); } }); } else { ToastUtil.show(context, "分享成功"); pop.dismiss(); finish(); } } @Override public void onError(io.rong.imlib.model.Message message, RongIMClient.ErrorCode errorCode) { pop.dismiss(); } }); } });
