これで、リストアイテムから値を取得するためにOnItemClickListenerを取得しようとしていました。現時点では、クリックは登録されていますが、値は通過していません。私のコードの関連部分をHere're：OnItemClickListenerを使用してリストアイテムからnull値を取得する
public class DiarySchedule extends ListActivity implements OnClickListener
{
private DiaryDataSource datasource;
private static final String TAG = "MAD Diary Schedule";
private String delTitle;
private String delDate;
private String delTime;
private String editTitle;
private String editDate;
private String editTime;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.diary_schedule);
datasource = new DiaryDataSource(this);
datasource.open();
List<DiaryEntry> values = datasource.getAllDiaryEntries();
DiaryScheduleAdapter adapter = new DiaryScheduleAdapter(this,values);
setListAdapter(adapter);
registerForContextMenu(getListView());
}
public class DiaryScheduleAdapter extends ArrayAdapter<DiaryEntry>
{
private LayoutInflater li;
public DiaryScheduleAdapter(Context context, List<DiaryEntry> values)
{
super(context, 0, values);
li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
DiaryEntry diaryEntry = getItem(position);
View v = convertView;
if (v == null)
{
v = li.inflate(R.layout.diary_schedule, null);
}
TextView date = (TextView)v.findViewById(R.id.scheduleListDate);
String initialDate = diaryEntry.getDate();
String formattedDate = ConvertToDate(initialDate);
date.setText(formattedDate);
TextView link = (TextView)v.findViewById(R.id.scheduleListLink);
link.setText(" at ");
TextView time = (TextView)v.findViewById(R.id.scheduleListTime);
time.setText(diaryEntry.getTime());
TextView title = (TextView)v.findViewById(R.id.scheduleListTitle);
title.setText(diaryEntry.getTitle());
v.setOnClickListener(new OnItemClickListener(position));
return v;
}
}
@Override
public boolean onCreateOptionsMenu (Menu menu)
{
new MenuInflater(getApplication()).inflate(R.menu.diary_menu, menu);
return (super.onCreateOptionsMenu(menu));
}
@Override
public boolean onOptionsItemSelected (MenuItem item)
{
switch (item.getItemId())
{
case R.id.add:
Intent intent = new Intent(DiarySchedule.this, DiaryAddEntry.class);
startActivity(intent);
break;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo)
{

inflater.inflate(R.menu.diary_context_menu, menu);
}
@Override

switch (item.getItemId())
{
case R.id.edit:

break;

Log.v(TAG, "Hopefully title is: " + delTitle + " with date of " + delDate + " and time of " + delTime);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Are you sure?").setPositiveButton("Yes", dialogClickListener)
.setNegativeButton("No", dialogClickListener).show();
break;
}
return super.onContextItemSelected(item);
}
DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
switch (which)
{
case DialogInterface.BUTTON_POSITIVE:
datasource.deleteDiaryEntry(delTitle, delDate, delTime);

//datasource.deleteAll();

break;
}
}
};
@Override

// TODO Auto-generated method stub
}
private class OnItemClickListener implements OnClickListener
{
private int mPosition;
OnItemClickListener(int position)
{
mPosition = position;
}
@Override
public void onClick(View v)
{
Log.v(TAG, "onItemClick at position" + mPosition);
final String title = (String) ((TextView) findViewById(R.id.scheduleListTitle)).getText();
System.out.println("Title is: " + title);
String date = (String) ((TextView) findViewById(R.id.scheduleListDate)).getText();
date = GetInfoConvertToDate(date);
System.out.println("Date is: " + date);
final String time = (String) ((TextView) findViewById(R.id.scheduleListTime)).getText();
System.out.println("Time is: " + time);
Intent descIntent = new Intent(DiarySchedule.this, DiaryDetailed.class);
descIntent.putExtra("title", title);
descIntent.putExtra("date", date);
descIntent.putExtra("time", time);
startActivity(descIntent);
}
}
}
それをデバッグOnItemClickListenerのOnClickメソッドに到達し、適切にそれを通過するが、ちょうど空の出てくる値を、ピックアップしていません。何か案は？おかげ
