我想从这样的一个的AsyncTask设置一些TextView中的文本:资源ID NOTFOUND时设置的TextView的文本从的AsyncTask
class InfoLoader extends AsyncTask<Params, String, Result>{
final String groupName;
final TextView populationTV;
final TextView passwordstateTV;
final TextView publicstateTV;
RoomInfo info;
protected InfoLoader(final String groupName,final TextView populationTV, final
TextView passwordstateTV, final TextView publicstateTV) {
super();
this.groupName = groupName;
this.populationTV = populationTV;
this.passwordstateTV = passwordstateTV;
this.publicstateTV = publicstateTV;
}
@Override
protected Result doInBackground(Params... params) {
try {
info =
MultiUserChat.getRoomInfo(MyService.connection,groupName+"@conference.reza-hp");
} catch (NoResponseException | XMPPErrorException
| NotConnectedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
new Handler(Looper.getMainLooper()).post(new Runnable() {
@Override
public void run() {
if(populationTV==null){
System.out.println("Its null");
}
if(info==null){
System.out.println("Info null");
}
populationTV.setText(info.getOccupantsCount());
if(info.isPasswordProtected()==true){
passwordstateTV.setText("Yes");
}else if(info.isPasswordProtected()==false){
passwordstateTV.setText("No");
}
if(info.isMembersOnly()==true){
publicstateTV.setText("Members Only");
}else if(info.isMembersOnly()==false){
publicstateTV.setText("Public");
}
}
});
return null;
}
}
的TextViews是从我的ListView,和IM确保它们不为空,但我取回此错误:

但即时通讯相当肯定,我做了一些这样的事之前,你看到了什么事错在这里家伙?
妈呀,怎么我傻的,生病尝试和回来尽快 – dasdas
