RxBus.getDefault().subscribe(this, QuantManager.DK_SHARE_MEDIA, RxBus.Callback<String> { s ->
            if ("1" == s) {
                requestDKShare()
            }
        })

原来的分享成功会刷新接口，并弹窗

    private fun requestDKShare() {

        val params = ArrayList<KeyValueData>()
        params.add(KeyValueData("userToken", UserManager.userToken()))
        params.add(KeyValueData("action", "share"))
        params.add(KeyValueData("courseid", "4357"))
        RxHttp.call(RequestCommand.COMMAND_DK_SHARE, params, QuantDkActiveResponse::class.java) { data ->
            refreshData()
            QuantDkMainDialog.newInstance(QuantDkMainDialog.TYPE_SHARE, data.message).show(supportFragmentManager, "QuantDkMainDialog")
        }
    }

改成局部变量的形式， transaction.commitAllowingStateLoss() 防止崩溃

    private fun requestDKShare() {

        val params = ArrayList<KeyValueData>()
        params.add(KeyValueData("userToken", UserManager.userToken()))
        params.add(KeyValueData("action", "share"))
        params.add(KeyValueData("courseid", "4357"))
        RxHttp.call(RequestCommand.COMMAND_DK_SHARE, params, QuantDkActiveResponse::class.java) { data ->
            refreshData()

            val dialog = QuantDkMainDialog.newInstance(QuantDkMainDialog.TYPE_SHARE, data.message)
            val transaction = supportFragmentManager.beginTransaction()
            transaction.add(dialog, "dialog")
            transaction.commitAllowingStateLoss()
        }
    }

相对于 qq，微博，等其他分享，微信分享 会回调WXEntryActivity类，这样QuantDKHomePlusActivity类就进入后台，supportFragmentManager就获取不到了，所以会引起崩溃

另外，只要微信分享获取不到

    private UMShareListener shareListener = new UMShareListener() {
        @Override
        public void onStart(SHARE_MEDIA platform) {

       }

        @Override
        public void onResult(SHARE_MEDIA platform) {

            if (context instanceof QuantDKHomePlusActivity) {
                RxBus.getDefault().post(QuantManager.DK_SHARE_MEDIA, "1");
            } else if (context instanceof QuantDKDetailPlusActivity) {
                RxBus.getDefault().post(QuantManager.DK_SHARE_MEDIA, "2");
            }

            Toast.makeText(context,"分享成功",Toast.LENGTH_LONG).show();
        }

        @Override
        public void onError(SHARE_MEDIA platform, Throwable t) {
            Toast.makeText(context,"分享失败"+t.getMessage(),Toast.LENGTH_LONG).show();
        }

        @Override
        public void onCancel(SHARE_MEDIA platform) {
            Toast.makeText(context,"取消分享",Toast.LENGTH_LONG).show();
        }
    };

需要在WXEntryActivity类中如下处理

    @Override
    public void onResp(BaseResp resp) {

        switch (resp.errCode) {
            case BaseResp.ErrCode.ERR_OK:

                if (resp instanceof SendAuth.Resp) {

                    String code = ((SendAuth.Resp) resp).code;

                    Intent intent = new Intent();
                    intent.putExtra("wxCode", code);
                    intent.setAction("wx_login");
                    sendBroadcast(intent);

                } else {

                    if (this.mWxHandler != null) {
                        try {
                            this.mWxHandler.getWXEventHandler().onResp(resp);
                        } catch (Exception var3) {
                            SLog.error(var3);
                        }
                    }

                    ToastTool.showToast("分享成功");
                }

                break;
            case BaseResp.ErrCode.ERR_USER_CANCEL:

                if (resp.getType() == 1) {

                    ToastTool.showToast("取消登录");
                } else if (resp.getType() == 2) {

                    ToastTool.showToast("取消分享");
                } else {

                }

                break;
            case BaseResp.ErrCode.ERR_AUTH_DENIED:

                ToastTool.showToast("授权失败");

                break;
            default:

                break;
        }

        finish();
    }

其实调用的是 super.onResp，但这样就会影响第三方登录，所以只在分享时调用

                    if (this.mWxHandler != null) {
                        try {
                            this.mWxHandler.getWXEventHandler().onResp(resp);
                        } catch (Exception var3) {
                            SLog.error(var3);
                        }
                    }

WXCallbackActivity 微信回调类的 onResp方法

    public void onResp(BaseResp resp) {
        SLog.I("WXCallbackActivity 分发回调");
        if (this.mWxHandler != null && resp != null) {
            try {
                this.mWxHandler.getWXEventHandler().onResp(resp);
            } catch (Exception var3) {
                SLog.error(var3);
            }
        }

        this.finish();
    }
