Answer 1

没找到Jsoup这个包，重新导入试试

Answer 2

您是说onClick这个按钮的代码吗？
<Button
            android:id="@+id/set"
            android:layout_width="100dp"
            android:layout_height="wrap_content"
            android:onClick="getFile"
            android:text="@string/set" />就是我贴出来的那段

Answer 3

我一开始引用了
jsoup-1.7.3-javadoc.jar
jsoup-1.7.3-sources.jar
jsoup-1.7.3.jar然后我删掉      jsoup-1.7.3-sources.jar
并在 java build path -->  order and export 里面勾选了相应jar文件之后就好了（如图）！ 谢谢~！

//onClick getFile
        public void getFile(View view)  {
            File input;
            TextView coursesList  = (TextView) findViewById(R.id.theList);
            TextView location = (TextView) findViewById(R.id.location);
            filePath = location.getText().toString();
         
            if(fileIsExists(filePath)){
                 
                input = new File(filePath);               
                try {
                    //parse the html file
                    Document doc;
                    Course course = new Course();
                    doc = Jsoup.parse(input, "UTF-8"); //经测试后，我认为是这句引起的程序崩溃
                    Elements links = doc.getElementsByAttributeValue("ALIGN","left");
                    int i = 0;
                    boolean needrecord = false;//in order to find the information needed
 
                    for (Element link : links) {//setText on the screen and save the information as a file
                          String linkText = link.text();
                          if(linkText.equals("EE")){//after String EE found, the course name, date, and instructor
                              needrecord = true;    //can be found in the fixed position
                          }
                          if(needrecord){
                              i++;
                              if(i == 4){//course name
                                    coursesList.setText(linkText+"       ");
                              }
                              if(i == 5){//date
                                    coursesList.setText(linkText+"      ");
                              }
                              if(i == 8){//instructor
                                    coursesList.setText(linkText+"   \n");
                                    needrecord = false;
                                    i = 0;
                              }
                          }
                    }
                                    flage = true;  
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    coursesList.setText("ERROR!"+e.toString());
                    e.printStackTrace();
                 
                }           
                              }//if
             
            else{
                coursesList.setText("File path is not right. Check the path and retype the path.");
            }
 
        }
问题已经解决了  谢谢~

终于让我找到这个帖子了！在布局文件中为标签绑定事件处理方法我总是出现这个问题，这个问题的原因是不是因为缺少jsoup这个包来在XML文件中解析然后就找不到所绑定的方法？怎么添加jsoup？是另外下载的吗？
