Helo i am trying to populate a listView with data stored in a sqLite. After i select a product i want all the reference of that product to go on the same line like i drew in the picture.
Can i make the ArrayAdapter put all records in the same xml?
My code looks like this: The cursor that returns all records:
public Cursor getAllRows() {
String where = null;
// query the DBAdapter
Cursor cursor = db.query(true, TABLE_NAME, ALL_KEYS, where, null, null, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
}
return cursor;
}
Adding data to arrayList:
public ArrayList<String> fromCursorToArrayListString(Cursor c){
ArrayList<String> result = new ArrayList<String>();
c.moveToFirst();
for(int i = 0; i < c.getCount(); i++){
String row_PRODUCT = c.getString(c.getColumnIndex(KEY_PRODUCT));
String row_PRICE = c.getString(c.getColumnIndex(KEY_PRICE));
String row_TYPE = c.getString(c.getColumnIndex(KEY_TYPE));
result.add(row_PRODUCT);
result.add(row_PRICE);
result.add(row_TYPE);
c.moveToNext();
}
return result;
}
In the mainActivity i wrote this:
ListView listView = (ListView) findViewById(R.id.new_list_listView);
Cursor cursor = newListDBAdapter.getAllRows();
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,R.layout.custom_product_layout_new_list,R.id.custom_product_layout_new_list_productName,newListDBAdapter.fromCursorToArrayListString(cursor));
listView.setAdapter(arrayAdapter);
CursorAdapter adapter more reliable for this . you just pass your Cursor to adapter so you no need to maintain any collection . you must follow few things
Adapter
public class YourCursorAdapter extends CursorAdapter {
public YourCursorAdapter(Context context, Cursor cursor, int flags) {
super(context, cursor, 0);
}
// The newView method is used to inflate a new view and return it,
// you don't bind any data to the view at this point.
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
return LayoutInflater.from(context).inflate(R.layout.your_item_view, parent, false);
}
// The bindView method is used to bind all data to a given view
// such as setting the text on a TextView.
@Override
public void bindView(View view, Context context, Cursor c) {
// Find fields to populate in inflated template
TextView tvproduct = (TextView) view.findViewById(R.id.tcproduct);
TextView tvPrice = (TextView) view.findViewById(R.id.tvPrice);
TextView tvType = (TextView) view.findViewById(R.id.tvType);
// Extract properties from cursor
String row_PRODUCT = c.getString(c.getColumnIndex(KEY_PRODUCT));
String row_PRICE = c.getString(c.getColumnIndex(KEY_PRICE));
String row_TYPE = c.getString(c.getColumnIndex(KEY_TYPE));
// Populate fields with extracted properties
tvproduct.setText(row_PRODUCT);
tvPrice.setText(row_PRICE);
tvType.setText(row_TYPE);
}
}
Retrieve the record from DB
public Cursor getAllRows() { String where = null;
// query the DBAdapter
Cursor cursor = db.query(true, TABLE_NAME, ALL_KEYS, where, null, null, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
}
return cursor;
}
Now set cursor to your adapter ,adapter set to listview
ListView listView = (ListView) findViewById(R.id.new_list_listView);
Cursor cursor = newListDBAdapter.getAllRows();
YourCursorAdapter arrayAdapter = new YourCursorAdapter(this, cursor);
listView.setAdapter(arrayAdapter );
