    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);
        }
    }
