Activity
에 ListView
을 사용하고 있으며 SQLite DB에서로드하는 데 시간이 걸리므로 사용자에게 ProgressDialog
이 표시되어 무언가가로드되고 있음을 알리고 싶었습니다. 별도의 스레드에서 작업을 실행하려고했지만 CalledFromWrongThreadException
이 표시됩니다.AsyncThread에서 ListView 어댑터를 설정할 수 없음
@Override
public void onCreate(Bundle savedInstanceState)
{
try
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.open_issues);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title);
//Set Window title.
final TextView title = (TextView) findViewById(R.id.customTitle);
if (title != null)
title.setText("Open Issues");
//Call Async Task to run in the background.
new LoadIssuesTask().execute();
}
catch (Exception e)
{
Errors.LogError(e);
}
}
그리고 LoadIssuesTask 코드 :
private class LoadIssuesTask extends AsyncTask<Void, Void, Cursor> {
ProgressDialog pdDialog = null;
protected void onPreExecute()
{
try
{
pdDialog = new ProgressDialog(OpenIssues.this);
pdDialog.setMessage("Loading Issues and Activities, please wait...");
pdDialog.show();
}
catch (Exception e)
{
Errors.LogError(e);
}
}
@Override
protected Cursor doInBackground(Void... params) {
LoadIssues();
return null;
}
@Override
protected void onPostExecute(Cursor c) {
pdDialog.dismiss();
pdDialog = null;
}
}
그리고 LoadIssues 코드 : IssueInfoAdapter에 대한
private void LoadIssues(){
//Set listview of Issues.
ListView lvIssues = (ListView)findViewById(R.id.lvIssues);
lvIssues.setOnItemClickListener(viewIssuesListener);
IssueCreator = new IssueInfoCreator(this, Integer.parseInt(AppPreferences.mDBVersion));
IssueCreator.open();
lvIssues.setAdapter(new IssueInfoAdapter(this, IssueCreator.queryAll()));
IssueCreator.close();
}
생성자 :
public IssueInfoAdapter(Context c, List<IssueInfo> list){
mListIssueInfo = list;
//create layout inflater.
mInflater = LayoutInflater.from(c);
}
그것은 THR의 여기 내 주요 Activity
코드입니다 .setAdapter 메서드의 오류가 LoadIssues()
안에 있기 때문에. ERROR :
