update sqlite not working in listview android
Question
i use listview, when i try to update the listview but not change
i put method updateTggl() in SaveData() , so when i save data, the list is change but not work
here is my method
private void updateTggl()
{
DatabaseHelper dbConnector = new DatabaseHelper(this);
if (getIntent().getExtras() != null)
{
dbConnector.updateTanggal(rowID,tglEt.getText().toString());
}
}
this is code updateTanggal Method
public void updateTanggal(long id, String tglb)
{
ContentValues editTgl = new ContentValues();
editTgl.put("tglb", tglb);
SQLiteDatabase db = this.getWritableDatabase();
db.update("petak_tetap", editTgl, "_id=" + id, null);
db.close();
}
code to call the listview
db = new DatabaseHelper(this);
constantsCursor = db.getReadableDatabase().rawQuery(
"SELECT _ID, alamat, tglb " + "FROM petak_tetap ORDER BY _ID",
null);
ListAdapter adapter = new SimpleCursorAdapter(this, R.layout.row,
constantsCursor, new String[] { DatabaseHelper.ID,
DatabaseHelper.ALAMAT, DatabaseHelper.TANGGAL_AKHIR },
new int[] { R.id.id, R.id.alamat, R.id.tglakhir });
setListAdapter(adapter);
registerForContextMenu(getListView());
here is full code activity

update sqlite not working in listview android
You did not specify which kind of adapter you are using. But probably some CursorAdapter .
So you should call cursor.requery() or you can perform query again to get fresh Cursor and then swap this new one into CursorAdapter.
Also you can try to use changeCursor() or swapCursor() on your Adapter if first approach wo't work.
yourAdapter.changeCursor(newCursor);
And if you are not using CursorAdapter there are method notifyDataSetChanged()
