Hi! im using an Async-Task and currently im using runOnUiThread in the
doInBackground method to refresh activities UI, this seems to be working but
on rotation it loses the data and im usng the
getLastNonConfigurationInstance and the onRetainNonConfigurationInstance
methods, here's the parent class method that calls the async task:
/**
* do asynctask for background work
*/
public void doAsyncTask(){
//get task back in case of rotation
task= (QuadrosMobileActivityTask)getLastNonConfigurationInstance();
if(task==null){
task= new QuadrosMobileActivityTask(this);
task.execute();
//add to the set of tasks
QuadrosMobileApplicationContext appliContext=
(QuadrosMobileApplicationContext)getApplicationContext();
appliContext.getAsyncTasks().add(task);
}else{
task.attach(this);
}
}
Here's the async task as normal class(non inner class) main methods;
@Override
protected void onPreExecute() {
Logger.write("QuadrosMobileActivityTask ", " AsyncTask pre execution "+
"Current Activity: "+activity.getClass().getName(), Logger.INFO);
if(QuadrosMobileActivity.themeId!=R.style.CustomThemeNoHeader){
activity.findViewById(R.id.progressView).setVisibility(ProgressBar.VISIBLE);
}
QuadrosMobileActivity.progressBarstate=ProgressBar.VISIBLE;
}
@Override
protected String doInBackground(Void... params) {
Logger.write("QuadrosMobileActivityTask ", "initialized", Logger.INFO);
return activity.*updateResultsInUi()*;
}
@Override
protected void onPostExecute(String result) {
Logger.write("QuadrosMobileActivityTask ", " AsyncTask post execution
"+"Current Activity: "+activity.getClass().getName(), Logger.INFO);
if(activity!=null)
Toast.makeText(activity, result, Toast.LENGTH_LONG).show();
//remove this task from collection
QuadrosMobileApplicationContext appliContext=
QuadrosMobileApplicationContext.getInstance();
appliContext.getAsyncTasks().remove(this);
//check if there's more tasks in the collection
if(appliContext.getAsyncTasks().isEmpty()){
if(QuadrosMobileActivity.themeId!=R.style.CustomThemeNoHeader){
activity.findViewById(R.id.progressView).setVisibility(ProgressBar.GONE);
}
QuadrosMobileActivity.progressBarstate=ProgressBar.GONE;
}
}
And the sub activities *updateResultsInUi() *method:
runOnUiThread(
new Runnable() {
@Override
public void run() {
((TextView)findViewById(R.id.nome_value)).setText(quadro.getNome());
//((TextView)findViewById(R.id.nif_value)).setText(quadro.getDadosPessoais().getNumeroContribuinte());
((TextView)findViewById(R.id.datanasc_value)).setText(DateTimeZoneUtils.getInstance().sqlLiteDateTimeFormat(quadro.getDadosPessoais().getDataNascimento()));
((TextView)findViewById(R.id.provincia_value)).setText(quadro.getResidencia().getProvincia());
((TextView)findViewById(R.id.municipio_value)).setText(quadro.getResidencia().getMunicipio());
((TextView)findViewById(R.id.comuna_value)).setText(quadro.getResidencia().getComuna());
((TextView)findViewById(R.id.bairro_value)).setText(quadro.getResidencia().getBairro());
((TextView)findViewById(R.id.rua_value)).setText(quadro.getResidencia().getRua());
}
}
);
Can i use the runOnUIThread method inside the doInBackground method of
AsyncTask??
regards,
