我用来调用Async类。我正面临着logcat中的一个问题，显示07-22 12：31：42.657：I / Choreographer（29254）：跳过31帧！应用程序可能在其主线程上做了太多工作。这个消息有时候也很粗鲁。我不明白为什么这会显示这条消息
我的代码是
class LoadSubmitteddoinback extends AsyncTask<URL, Integer, Long>
{
MyProgressDialog dialog;JSONObject jobject=null;JSONArray jarraysubmit=null;
String jsonresult="";
int strat;
public LoadSubmittedbloopsdoinback(int strat) {
super();
this.strat = strat;
}
protected void onPreExecute()
{
if(boolforprogressdialogmyfeed==true){
dialog=MyProgressDialog.show(getActivity(), null,null);
dialog.getWindow().setGravity(Gravity.CENTER);
footerView.setVisibility(View.GONE);
}else{
loading=true;
footerView.setVisibility(View.VISIBLE);
// listfortestmyfeed.addFooterView(footerView);
}
}
@Override
protected Long doInBackground(URL... arg0) {
try {
jsonresult= UrltoValue.getValuefromUrl(DataUrls.submittedsurl+"userid="+userid+"&category="+category+"&start="+strat+"&userid2="+quickuserid);
Log.e("url is. submitted .load.", DataUrls.submittedsurl+"userid="+userid+"&category="+category+"&start="+strat+"&userid2="+quickuserid);
jobject = new JSONObject(jsonresult);
jarraysubmit = jobject.getJSONArray("urls");
if(jarraysubmit.length()!=0){
for(int i=0;i<jarraysubmit.length();i++){
// JSONObject jobject= jarray.getJSONObject(i);
JSONObject jobject1= jarraysubmit.getJSONObject(i);
Bloop bloop= new Bloop();
bloop.setBloopid(jobject1.getString("id"));
bloop.setUserid(jobject1.getString("userid"));
bloop.setTitle(jobject1.getString("title"));
bloop.setDescription(jobject1.getString("description"));
bloop.setThumb(jobject1.getString("thumb"));
bloop.setKeywords(jobject1.getString("keywords"));
bloop.setAuthorPic(jobject1.getString("authorpic"));
bloop.setViewscount(jobject1.getString("Viewscount"));
bloop.setCommentscount(jobject1.getString("commentscount"));
try{
bloop.setUsercommentstatus(jobject1.getString("usercommentstatus"));
bloop.setPublicvalue(jobject1.getString("Public"));
bloop.setNsfw(jobject1.getString("NSFW"));}catch(Exception e){e.printStackTrace();}
bloops.add(bloop);
getActivity(). runOnUiThread(new Runnable() {
@Override
public void run() {
myfeedAdapter.notifyDataSetChanged();
Utility.setListViewHeightBasedOnChildren(listfortestmyfeed);
}
});
//
}
}else{
listfortestmyfeed.removeFooterView(footerView);
listfortestmyfeed.setOnScrollListener(null);
}
loading=false;
} catch (Exception e1) {
e1.printStackTrace();
}
return null;
}
@SuppressLint("NewApi")
protected void onPostExecute(Long result) {
try{
if(boolforprogressdialogmyfeed==true){
dialog.dismiss();
boolforprogressdialogmyfeed=false;
}
}catch(Exception e){e.printStackTrace();}
}
以上是我的异步课。我没有发现错误，请指导我错误的地方。感谢所有
