开发中分享操作往往经常遇到，而且还是一些比较大型一定的平台，如微信，QQ，微博等。写这篇博客主要是把微信的的分享和相关操作表达一下，分享可以包含：文字，视频，音乐，图片等分享。
分享可以有 分享给好友，群，朋友圈等。
效果如下图：（注意：功能根据自己的需要选择就可以了）
准备工作：
微信开放平台创建应用，操作步骤请看博客：Android之微信开放平台创建应用
成功之后得到AppId，放入项目中。
public class Constants {// APP_ID 替换为你的应用从官方网站申请到的合法appId==public static final String APP_ID = "wx1b73fd7b49ffa027";public static class ShowMsgActivity {public static final String STitle = "showmsg_title";public static final String SMessage = "showmsg_message";public static final String BAThumbData = "showmsg_thumb_data";}
public class AppRegister extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {final IWXAPI api = WXAPIFactory.createWXAPI(context, null);// 将该app注册到微信api.registerApp(Constants.APP_ID);}}
文本分享代码：
// 初始化一个WXTextObject对象WXTextObject textObj = new WXTextObject();textObj.text = text;// 用WXTextObject对象初始化一个WXMediaMessage对象WXMediaMessage msg = new WXMediaMessage();msg.mediaObject = textObj;// 发送文本类型的消息时，title字段不起作用msg.title = "Will be ignored";msg.description = text;// 构造一个ReqSendMessageToWX.Req req = new SendMessageToWX.Req();req.transaction = buildTransaction("text"); // transaction字段用于唯一标识一个请求req.message = msg;/*** 判断是否是朋友圈*/req.scene = isTimelineCb.isChecked() ? SendMessageToWX.Req.WXSceneTimeline : SendMessageToWX.Req.WXSceneSession;// 调用api接口发送数据到微信api.sendReq(req);
图片分享代码：（包含 本地图片，SD卡图片，网络图片）
Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.send_img);WXImageObject imgObj = new WXImageObject(bmp);WXMediaMessage msg = new WXMediaMessage();msg.mediaObject = imgObj;Bitmap thumbBmp = Bitmap.createScaledBitmap(bmp, THUMB_SIZE, THUMB_SIZE, true);bmp.recycle();msg.thumbData = Util.bmpToByteArray(thumbBmp, true); // 设置所图；SendMessageToWX.Req req = new SendMessageToWX.Req();req.transaction = buildTransaction("img");req.message = msg;req.scene = isTimelineCb.isChecked() ? SendMessageToWX.Req.WXSceneTimeline : SendMessageToWX.Req.WXSceneSession;api.sendReq(req);
音乐分享代码
WXMusicObject music = new WXMusicObject();music.musicUrl="http://staff2./~wdw/softdown/index.asp/0042515_05.ANDY.mp3";WXMediaMessage msg = new WXMediaMessage();msg.mediaObject = music;msg.title = "标题";msg.description = "描述信息";Bitmap thumb = BitmapFactory.decodeResource(getResources(), R.drawable.send_music_thumb);msg.thumbData = Util.bmpToByteArray(thumb, true);SendMessageToWX.Req req = new SendMessageToWX.Req();req.transaction = buildTransaction("music");req.message = msg;req.scene = isTimelineCb.isChecked() ? SendMessageToWX.Req.WXSceneTimeline : SendMessageToWX.Req.WXSceneSession;api.sendReq(req);
视频分享代码
WXVideoObject video = new WXVideoObject();video.videoUrl = "url....mp4";//mp4视频路径WXMediaMessage msg = new WXMediaMessage(video);msg.title = "标题";msg.description = "描述信息";Bitmap thumb = BitmapFactory.decodeResource(getResources(), R.drawable.send_music_thumb); msg.thumbData = Util.bmpToByteArray(thumb, true); SendMessageToWX.Req req = new SendMessageToWX.Req(); req.transaction = buildTransaction("video"); req.message = msg; req.scene = isTimelineCb.isChecked() ? SendMessageToWX.Req.WXSceneTimeline : SendMessageToWX.Req.WXSceneSession; api.sendReq(req);
网页分享代码：
WXWebpageObject webpage = new WXWebpageObject();webpage.webpageUrl = "";WXMediaMessage msg = new WXMediaMessage(webpage);msg.title = "标题";msg.description = "描述信息";Bitmap thumb = BitmapFactory.decodeResource(getResources(), R.drawable.send_music_thumb);msg.thumbData = Util.bmpToByteArray(thumb, true);SendMessageToWX.Req req = new SendMessageToWX.Req();req.transaction = buildTransaction("webpage");req.message = msg;req.scene = isTimelineCb.isChecked() ? SendMessageToWX.Req.WXSceneTimeline : SendMessageToWX.Req.WXSceneSession;api.sendReq(req);
等等。
