Android之微信开放平台实现分享（分享好友和朋友圈）

来源：互联网发布：泰格软件使用教程编辑：程序博客网时间：2024/05/20 23:39

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 {    @Override    public 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Req                        SendMessageToWX.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() ?
