I am generating an events dynamically. These events data I am storing in sqlite database. Now I want to retrieve data of the clicked event. I tried to retrieve data but always getting 0th id data.
Generating events function :
private void createEvent(LayoutInflater inflater, ViewGroup dayplanView, int fromMinutes, int toMinutes, String title) {
final View eventView = inflater.inflate(R.layout.event_view, dayplanView, false);
RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) eventView.getLayoutParams();
RelativeLayout container = (RelativeLayout) eventView.findViewById(R.id.container);
TextView tvTitle = (TextView) eventView.findViewById(R.id.textViewTitle);
if (tvTitle.getParent() != null)
((ViewGroup) tvTitle.getParent()).removeView(tvTitle);
tvTitle.setText(title);
int distance = (toMinutes - fromMinutes);
layoutParams.topMargin = dpToPixels(fromMinutes + 9);
layoutParams.height = dpToPixels(distance);
eventView.setLayoutParams(layoutParams);
dayplanView.addView(eventView);
container.addView(tvTitle);
eventView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
i = new Intent(getActivity(),AddEventActivity.class);
startActivity(i);
}
});
}
This is my attempt to get data:
db = new EventTableHelper(getApplication());
eventData = new EventData();
if(editMode)//true
{
eventData = events.get(id);
Toast.makeText(getApplicationContext(),String.valueOf(id),Toast.LENGTH_LONG).show();
title.setText(eventData.getTitle());
eventTitle = title.getText().toString();
db.updateEvent(eventData);
Toast.makeText(getApplicationContext(),"Edit mode",Toast.LENGTH_LONG).show();
Log.i("Log","save mode");
}
I have EventTableHelper in that i have created functions to get event,update and delete events.
public class EventTableHelper extends SQLiteOpenHelper {
private static final String TABLE = "event";
private static final String KEY_ID = "id";
private static final String KEY_TITLE = "title";
private static final String KEY_FROM_DATE = "datefrom";
private static final String KEY_TO_DATE = "dateto";
private static final String KEY_LOCATION = "location";
private static final String KEY_DAY_OF_WEEK = "dayofweek";
public EventTableHelper(Context context) {
super(context, Constants.DATABASE_NAME, null, Constants.DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
}
public void createTable(SQLiteDatabase db){
String CREATE_EVENTS_TABLE = "CREATE TABLE " + TABLE+ "("
+ KEY_ID + " INTEGER PRIMARY KEY,"
+ KEY_TITLE + " TEXT,"
+ KEY_FROM_DATE + " DATE,"
+ KEY_TO_DATE + " DATE,"
+ KEY_DAY_OF_WEEK + " TEXT "
+ KEY_LOCATION + " TEXT" + ")";
db.execSQL(CREATE_EVENTS_TABLE);
}
// Upgrading database
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE);
// createTable(db);
// onCreate(db);
}
public void addEvent(EventData event) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(KEY_TITLE,event.getTitle());
values.put(KEY_FROM_DATE, event.getFromDate());
values.put(KEY_TO_DATE,event.getToDate());
values.put(KEY_DAY_OF_WEEK,event.getDayOfWeek());
values.put(KEY_LOCATION,event.getLocation());
db.insert(TABLE, null, values);
db.close();
}
EventData getEvent(int id) {
SQLiteDatabase db = this.getReadableDatabase();
EventData eventData = new EventData();
Cursor cursor = db.query(TABLE, new String[]{KEY_ID,
KEY_TITLE, KEY_FROM_DATE, KEY_TO_DATE,KEY_DAY_OF_WEEK, KEY_LOCATION}, KEY_ID + "=?",
new String[]{String.valueOf(id)}, null, null, null, null);
if( cursor != null && cursor.moveToFirst() ) {
eventData = new EventData(Integer.parseInt(cursor.getString(0)), cursor.getString(1), cursor.getString(2),
cursor.getString(3), cursor.getString(4), cursor.getString(5));
}
return eventData;
}
public List<EventData> getAllEvents() {
List<EventData> conList = new ArrayList<EventData>();
String selectQuery = "SELECT * FROM " + TABLE;
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
if (cursor.moveToFirst()) {
do {
EventData event = new EventData();
event.setId(Integer.parseInt(cursor.getString(0)));
event.setTitle(cursor.getString(1));
event.setFromDate(cursor.getString(2));
event.setToDate(cursor.getString(3));
event.setLocation(cursor.getString(4));
conList.add(event);
} while (cursor.moveToNext());
}
return conList;
}
}
I want to show data and update data if changes made.
Whats going wrong?
