鸿蒙开发遇到的API调用问题

想要调用多个API，但是点击按钮是出现闪退，无法呈现页面内容，请大家帮忙看一下，代码如下：

 button1.setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {

                TaskDispatcher taskDispatcher=getGlobalTaskDispatcher(TaskPriority.DEFAULT);
                taskDispatcher.asyncDispatch(new Runnable() {
                    @Override
                    public void run() {
                        //String inputword=textField1.getText();
                        String url="https://v2.alapi.cn/api/one?token=LwExDtUWhF3rH5ib";
                        String method="GET";
                        String result=APIRequest.URLRequest(url,method) ;

                        String[] pack1=new String[3];
                        pack1[0]=JsonParse.parseTitle(result);
                        pack1[1]=JsonParse.parseSubTitle(result);
                        pack1[2]=JsonParse.parseContent(result);
                        pack1[2]= HTMLChange.delHTMLTag(pack1[2]);

                        InnerEvent evt=InnerEvent.get(1);
                        evt.object=pack1;
                        eventHandler.sendEvent(evt);
                    }
                });

            }
        });

        eventRunner=EventRunner.getMainEventRunner();
        eventHandler= new XEventHandler(eventRunner);

        Intent intent1=new Intent();
//获取笑话按钮
        button3.setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                TaskDispatcher taskDispatcher3 = getGlobalTaskDispatcher(TaskPriority.DEFAULT);
                taskDispatcher3.asyncDispatch(new Runnable() {
                    @Override
                    public void run() {
                        String url ="http://v.juhe.cn/joke/content/list.php?key=d1ea03b16d3129829962c977e90c4089&page=2&pagesize=10&sort=asc&time=1418745237";
                        String method="GET";
                        String result=APIRequest.URLRequest(url,method);
                        button3.setText("正在访问，请稍后");
                    }
                });


            }
        });

        eventRunner=EventRunner.getMainEventRunner();
        eventHandler= new XEventHandler(eventRunner);

        Intent intent2=new Intent();
//获取历史上的今天按钮
        button4.setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                TaskDispatcher taskDispatcher2 = getGlobalTaskDispatcher(TaskPriority.DEFAULT);
                taskDispatcher2.asyncDispatch(new Runnable() {
                    @Override
                    public void run() {
                        String url ="http://v.juhe.cn/todayOnhistory/queryEvent.php?key=61d3edc3abb6bceb5d4bd04b5aa7b44b&date=1/1";

                    }

            }
        });

        Intent intent3=new Intent();

//获取新闻按钮
        button5.setClickedListener(new Component.ClickedListener() {
            @Override

                        button5.setText("正在访问，请稍后");
                    }
                }));

好像遇到过类似的问题，一行代码的问题，通过一步步断点可以定位的。

建议弹出对话框，或者打印日志跟踪一下变量的值。

跟踪执行一下，看看哪里报错，把错误发给我。
