pullRefresh = (PullRefresh) findViewById(R.id.pullrefresh);      listView = (ListView) findViewById(R.id.listview);      View header = findViewById(R.id.header);      View footer = findViewById(R.id.footer);        PullRefresh.CallBack callBack = new PullRefresh.CallBack() {          @Override          public boolean CanotPullDown() {              if (listView.getFirstVisiblePosition() == 0) {                  View first = listView.getChildAt(0);                  if (first.getTop() == 0)                      return true;              }              return false;          }            @Override          public boolean CanotPullUp() {              if (listView.getLastVisiblePosition() == listView.getCount() - 1) {                  View last = listView.getChildAt(listView.getChildCount() - 1);                  if (Math.abs(listView.getBottom() - last.getBottom()) < 2)                      return true;              }              return false;          }      };      PullRefresh.Task task = new PullRefresh.Task() {          @Override          public void HeaderTask() {              new Thread() {                  @Override                  public void run() {                      try {                          sleep(3000);                      } catch (InterruptedException e) {                          e.printStackTrace();                      }                      runOnUiThread(new Runnable() {                          @Override                          public void run() {                              HeaderTaskFinish();                          }                      });                  }              }.start();          }            @Override          public void FooterTask() {              new Thread() {                  @Override                  public void run() {                      try {                          sleep(3000);                      } catch (InterruptedException e) {                          e.printStackTrace();                      }                      runOnUiThread(new Runnable() {                          @Override                          public void run() {                              FooterTaskFinish();                          }                      });                  }              }.start();          }      };      //使用头部和尾部      pullRefresh.UseAll(callBack,header, listView,footer, new SimpleHeaderHolder(this), new SimpleFooterHolder(this),task );      //只使用头部      //pullRefresh.UseHeader(callBack,header,listView,new SimpleHeaderHolder(this),task);      //只使用尾部      //pullRefresh.UseFooter(callBack,footer,listView,new SimpleFooterHolder(this),task);          List<String> stringList = new ArrayList<String>();      for(int i=0;i<20;i++){          stringList.add("String:"+i);      }        adapter = new Adapter(this,stringList);      listView.setAdapter(adapter);  }    private void HeaderTaskFinish() {      if (tag%2==0){          pullRefresh.headerEndSuccess();          adapter.addDataToHeader();          adapter.notifyDataSetChanged();      }      else{          pullRefresh.headerEndFailed();      }      tag++;  }    private void FooterTaskFinish() {      if (tag%2==0){          pullRefresh.footerEndSuccess();          adapter.addDataToFooter();          adapter.notifyDataSetChanged();      }      else{          pullRefresh.footerEndFailed();      }      tag++;  }
