私は本当にこれで立ち往生していて、先に進むことができません.Googleカレンダーのイベントをリストビューに入力しようとしていますが、結果が表示されません. このような長いコードを投稿して申し訳ありませんが、本当に立ち往生しています!! 私の活動
public class EventListActivity extends Activity {
private List<Events> events = new ArrayList<Events>();
private Handler handler = new Handler();
private ProgressDialog progressBar;
private SelectableEventsAdapter eventsAdapter;
@Override
public void onCreate(Bundle savedInstance) {
super.onCreate(savedInstance);
getAccount();
setContentView(R.layout.layout_main);
setEventsListView();
}
private void setEventsListView() {
Log.i("ReachedsetEvents", "Reached set Events view 1");
final ListView eventsListView = (ListView) findViewById(R.id.list_main);
eventsAdapter = new SelectableEventsAdapter(this, events);
//eventsAdapter.getView(0, eventsListView, eventsListView);
eventsAdapter.setAdapter(eventsAdapter);
Log.i("ReachedsetEvents", "Reached set Events view 2");
eventsAdapter.sort();
private void retrieveEvents() {
// Retrieves the attendees on a separate thread.
new Thread(new Runnable() {
public void run() {
EventsRetriever eventsRetriever =
new EventsRetriever(EventListActivity.this, OAuthManager.getInstance()
.getAccount());
final List<Events> newevents = eventsRetriever.getEvents();
Log.i("reachedRetrieve", "reached retrieve");
// Update the progress bar
handler.post(new Runnable() {
public void run() {
if (newevents != null) {
events.clear();
events.addAll(newevents);
eventsAdapter.sort();
eventsAdapter.notifyDataSetChanged();
}
Log.d(Constants.TAG, "Got attendees, dismissing progress bar");
if (progressBar != null) {
progressBar.dismiss();
Log.d(Constants.TAG, "Progress bar should have been dismissed");
}
}
});
}
}).start();
// Show a progress bar while the attendees are retrieved from the phone's
// database.
progressBar =
ProgressDialog.show(this, null, getString(R.string.retrieve_contacts_wait_text), true);
}
@Override
protected void onResume() {
super.onResume();
// getAccount();
}
/**
* Prompt user to choose an account and retrieve attendees from phone's
* database.
*/
private void getAccount() {
OAuthManager.getInstance().doLogin(false, this, new OAuthManager.AuthHandler() {
public void handleAuth(Account account, String authToken) {
if (account != null) {
retrieveEvents();
}
}
});
}}
私のカスタムアダプター
public SelectableEventsAdapter(Context context, List<Events> items) {
super(context, R.layout.layout_main,items);
inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
Events item = getItem(position);
LinearLayout eventsView = getView(convertView);
setViews(item, eventsView);
return eventsView;
}
private LinearLayout getView(View convertView) {
Log.i("Reached", "Reached getView long");
LinearLayout eventsView;
if (convertView == null) {
eventsView = new LinearLayout(getContext());
inflater.inflate(R.layout.layout_main,eventsView,true);
} else {
eventsView = (LinearLayout) convertView;
}
return eventsView;
}
private void setViews(Events item, LinearLayout eventsView) {
setTitleView(item, eventsView);
}
private void setTitleView(Events item, LinearLayout eventsView) {
ListView titleView = (ListView) eventsView.findViewById(R.id.list_main);
titleView.setEnabled(true);
//titleView.setText(item.title);
}
イベントを取得するためのレトリーバー:
public EventsRetriever(Activity activity, Account account) {
this.activity = activity;
this.account = account;
}
public static final String[] FIELDS = {
CalendarContract.Events.TITLE,
CalendarContract.Events.DESCRIPTION,
CalendarContract.Events.ORGANIZER,
CalendarContract.Events.STATUS,
CalendarContract.Events.DTSTART,
CalendarContract.Events.EVENT_LOCATION,
};
public static final Uri CALENDAR_URI = Uri.parse("content://com.android.calendar/calendars");
String[] selectionArgs = new String[] {CalendarServiceBuilder.ACCOUNT_NAME, Constants.ACCOUNT_TYPE,
CalendarServiceBuilder.ACCOUNT_NAME};
/**
* Get the list of user's contacts.
*
* @return The list of contacts.
*/
public List<Events> getEvents() {
List<Events> result = new ArrayList<Events>();
ContentResolver cr = activity.getContentResolver();
Cursor cursor =
cr.query(CalendarContract.Events.CONTENT_URI, FIELDS,null,null, null);
try {
if(cursor.getCount() > 0) {
while (cursor.moveToNext()) {
String title =cursor.getString(cursor.getColumnIndex(
CalendarContract.Events.TITLE));
String description = cursor.getString(cursor.getColumnIndex(
CalendarContract.Events.DESCRIPTION));
String organizer = cursor.getString(cursor.getColumnIndex(
CalendarContract.Events.ORGANIZER));
String status = cursor.getString(cursor.getColumnIndex(
CalendarContract.Events.STATUS));
String location = cursor.getString(cursor.getColumnIndex(
CalendarContract.Events.EVENT_LOCATION));
result.add(new Events(title,description,organizer,status,location));
Log.i("Reachedretriever", "Reached retriever");
}
}}
finally {
cursor.close();
}
return result;
}}
