问题描述
我想要一个活动转换为片段。在 runOnUiThread
错误标记。在过去的:
I'm trying to convert an Activity to fragment. The error mark on runOnUiThread
.on the past:
GoogleActivityV2从活动延伸。 runOnUiThread类 ExecuteTask。嵌套的活动类ExecuteTask。
(运行正常)现在:
GoogleActivityV2从片段延伸。 runOnUiThread类 ExecuteTask。嵌套的活动类ExecuteTask。 (上的错误 runOnUiThread)
这是我的code
public class GoogleActivityV2 extends SherlockMapFragment implements OnMapClickListener , OnMapLongClickListener , OnCameraChangeListener , TextWatcher {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View rootView = inflater.inflate(R.layout.activity_googlev2, container, false);
Init();
adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_dropdown_item_1line);
textView = (AutoCompleteTextView) getView().findViewById(R.id.autoCompleteTextView1);
return rootView;
}
public void onCameraChange(CameraPosition arg0){
// TODO Auto-generated method stub
}
public void onMapLongClick(LatLng arg0){
llLoc = arg0;
stCommand = "onTouchEvent";
lp = new ExecuteTask();
lp.execute();
}
public void onMapClick(LatLng arg0){
// TODO Auto-generated method stub
}
class ExecuteTask extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute(){
super.onPreExecute();
if(stCommand.compareTo("AutoCompleteTextView") != 0) {
pDialog = new ProgressDialog(getActivity());
pDialog.setMessage(Html.fromHtml("<b>Search</b><br/>Loading ..."));
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
}
protected String doInBackground(String ... args){
do something
return null;
}
@Override
protected void onPostExecute(String file_url){
if(stCommand.compareTo("AutoCompleteTextView") != 0) pDialog.dismiss();
runOnUiThread(new Runnable() {
public void run(){
do something
}
});
}
}
public void afterTextChanged(Editable s){
// TODO Auto-generated method stub
}
public void beforeTextChanged(CharSequence s, int start, int count, int after){
// TODO Auto-generated method stub
}
public void onTextChanged(CharSequence s, int start, int before, int count){
// TODO Auto-generated method stub
}
}
错误说:
the error says:
我该如何解决这个问题?
how can I fix this error?
推荐答案
试试这个: getActivity()runOnUiThread(新的Runnable ...
这是因为:
1)隐这
在调用 runOnUiThread
是指AsyncTask的,不是你的片段。
1) the implicit this
in your call to runOnUiThread
is referring to AsyncTask, not your fragment.
2)片段
没有runOnUiThread
2) Fragment
doesn't have runOnUiThread

然而活动
作用:

请注意,这只是执行的Runnable
如果您已经在主线程,并使用处理程序
如果你不是在主线程。您可以在片段实施处理程序
如果你不想担心这
,它实际上上下文非常简单:
Note that this just executes the Runnable
if you're already on the main thread, and uses a Handler
if you aren't on the main thread. You can implement a Handler
in your fragment if you don't want to worry about the context of this
, it's actually very easy:

编辑:@rciovati是对的,你是在 onPostExecute
,这是已经在主线程
@rciovati is right, you are in onPostExecute
, that's already on the main thread.
