Pass ROWID in ListView to new Activity when clicked - sql

Question

Very new to programming here. I am working on an android application that allows the user to create and manage a database for food products that he has at home. Currently the SQL database allows you to create new database entries where each entry consists of a rowid, a product name, the amount you have of the product and finally an expiry date.
Then a ListView is populated with any existing data in the database and an OnItemClickListener for this ListView is setup to handle a click event so that if the user clicks on a row in the ListView he is send to a new edit activity. Here he can edit the name, the amount and the expiry date if needed.
Now I am trying to retrieve the data (name, amount, date) when a specific row is clicked to send it to the next activity and here's what I've got so far..
Setup a public cursor in the SQL database to get all KEYS for a specific rowid:
public static final String[] ALL_KEYS = new String[] {KEY_ROWID, KEY_NAME, KEY_AMOUNT, KEY_DATE};
public Cursor getRow(long rowId) {
String where = KEY_ROWID + "=" + rowId;
Cursor c = ourDatabase.query(true, DATABASE_TABLE, ALL_KEYS, where, null, null, null, null, null);
if (c != null) {
c.moveToFirst();
}
return c;
}
Then in the activity with the ListView I have the following set up to launch the new edit activity:
private void listViewItemClick(){
ListView ourList = (ListView) findViewById(R.id.lvProducts);
ourList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
Intent openProductsEdit = new Intent(Products.this,
ProductsEdit.class);
startActivity(openProductsEdit);
finish();
}
});
}
And finally I would like to set the EditTexts in my edit activity to the data passed on during the click event:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.products_edit);
initiate();
Intent getProductName = getIntent();
String productName = getProductName.getStringExtra("productName");
etName.setText(productName);
Intent getProductAmount = getIntent();
String productAmount = getProductAmount.getStringExtra("productAmount");
etAmount.setText(productName);
Intent getProductDate = getIntent();
String productDate = getProductDate.getStringExtra("productDate");
etDate.setText(productName);
I have been trying to retrieve the specific data for a clicked row through the cursor I have setup in the SQL database and then pass it on with openProductsEdit.putExtra in the onItemClick method, but I can't seem to successfully connect the two together.
Any suggestions on how to solve this would be greatly appreciated.
EDIT: I solved my problem by coding my onSetItemClickListener like this
private void listViewItemClick(){
final ListView ourList = (ListView) findViewById(R.id.lvProducts);
ourList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
Cursor cursor = (Cursor) ourList.getItemAtPosition(position);
Intent openProductsEdit = new Intent(Products.this,
ProductsEdit.class);
int rowid = cursor.getInt(0);
String name = cursor.getString(1);
String amount = cursor.getString(2);
String date = cursor.getString(3);
openProductsEdit.putExtra("rowid", rowid);
openProductsEdit.putExtra("name", name);
openProductsEdit.putExtra("amount", amount);
openProductsEdit.putExtra("date", date);
startActivity(openProductsEdit);
finish();
}
});
Here the cursor.getString(1) sets a string to the second column of the selected row (in this case a product name). This is then passed on to an edit activity where the data is put into corresponding EditTexts.
PROBLEM SOLVED! ;)
