1.先下载微信分享的jar包放在lib目录下，并且添加依赖，

清单文件添加

<activity            android:name=".wxapi.WXEntryActivity"            android:exported="true">//产生回调        </activity>

2.在工程下新建如图所示的包和Activity

Activity里面的内容主要是创建微信api并且注册返回回调值

private final String APP_ID= "wx108514397eea5f77";    private IWXAPI api;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_wxentry);        api = WXAPIFactory.createWXAPI(this, APP_ID, false);        api.registerApp(APP_ID);        api.handleIntent(getIntent(), this);    }    @Override    public void onReq(BaseReq baseReq) {    }    @Override    public void onResp(BaseResp baseResp) {        switch (baseResp.errCode) {            case BaseResp.ErrCode.ERR_OK:                Toast.makeText(this, "分享成功", Toast.LENGTH_LONG).show();                break;            case BaseResp.ErrCode.ERR_USER_CANCEL:                Toast.makeText(this, "分享取消", Toast.LENGTH_LONG).show();                break;            case BaseResp.ErrCode.ERR_AUTH_DENIED:                Toast.makeText(this, "被拒绝", Toast.LENGTH_LONG).show();                break;            default:                Toast.makeText(this, "未知错误", Toast.LENGTH_LONG).show();                break;        }        finish();    }

3.接着就是在要使用的地方调用

 private void weiChat(int flag) {        if (!api.isWXAppInstalled()) {            return;        }        //创建一个WXWebPageObject对象，用于封装要发送的Url        WXWebpageObject webpage = new WXWebpageObject();        webpage.webpageUrl = "http://www.baidu.com/";        //创建一个WXMediaMessage对象        WXMediaMessage msg = new WXMediaMessage(webpage);        msg.title = "测试";        msg.description = "ceshi ";        SendMessageToWX.Req req = new SendMessageToWX.Req();        req.transaction = String.valueOf(System.currentTimeMillis());//transaction字段用于唯一标识一个请求，这个必须有，否则会出错        req.message = msg;        //表示发送给朋友圈  WXSceneTimeline  表示发送给朋友  WXSceneSession        req.scene = flag == 0 ? SendMessageToWX.Req.WXSceneSession : SendMessageToWX.Req.WXSceneTimeline;        api.sendReq(req);    }
