I am using SwipeFlingAdapterView
and I am fetching data from the MySQL database.
Variables:
private ArrayList<String> al;
private ArrayAdapter<String> arrayAdapter;
private int i;
SwipeFlingAdapterView flingContainer;
JSONParser jParser = new JSONParser();
ArrayList<HashMap<String, String>> productsList;
// url to get all products list
private static String url_all_products = "http://example.com/items.php";
// JSON Node names
private static final String TAG_SUCCESS = "success";
private static final String TAG_PRODUCTS = "items";
private static final String TAG_NAME = "name";
// products JSONArray
JSONArray products = null;
When I am using below code then it will bind data :
al.add("php");
al.add("c");
al.add("python");
al.add("java");
// choose your favorite adapter
arrayAdapter = new ArrayAdapter<String>(MainActivity.this,
R.layout.item, R.id.tv_portal, al);
// set the listener and the adapter
flingContainer.setAdapter(arrayAdapter);
flingContainer
.setFlingListener(new SwipeFlingAdapterView.onFlingListener() {
@Override
public void removeFirstObjectInAdapter() {
// this is the simplest way to delete an object from the
// Adapter (/AdapterView)
Log.d("LIST", "removed object!");
al.remove(0);
arrayAdapter.notifyDataSetChanged();
}
@Override
public void onLeftCardExit(Object dataObject) {
// Do something on the left!
// You also have access to the original object.
// If you want to use it just cast it (String)
// dataObject
Toast.makeText(MainActivity.this, "Left!",
Toast.LENGTH_SHORT).show();
}
@Override
public void onRightCardExit(Object dataObject) {
Toast.makeText(MainActivity.this, "Right!",
Toast.LENGTH_SHORT).show();
}
@Override
public void onAdapterAboutToEmpty(int itemsInAdapter) {
// Ask for more data here
/*
* al.add("XML ".concat(String.valueOf(i)));
* arrayAdapter.notifyDataSetChanged(); Log.d("LIST",
* "notified"); i++;
*/
}
@Override
public void onScroll(float scrollProgressPercent) {
// TODO Auto-generated method stub
}
});
// Optionally add an OnItemClickListener
flingContainer
.setOnItemClickListener(new SwipeFlingAdapterView.OnItemClickListener() {
@Override
public void onItemClicked(int itemPosition,
Object dataObject) {
// Toast.make(MainActivity.this, "Clicked!");
}
});
It is loading all right.
But when I used below code, it is not bind the data even no error comes:
class LoadAllProducts extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(MainActivity.this);
pDialog.setMessage("Loading products. Please wait...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
protected String doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("itemid", "1"));
// getting JSON string from URL
JSONObject json = jParser.makeHttpRequest(url_all_items, "GET",
params);
// Check your log cat for JSON reponse
Log.d("All Products: ", json.toString());
try {
// Checking for SUCCESS TAG
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// products found
// Getting Array of Products
products = json.getJSONArray(TAG_PRODUCTS);
// looping through All Products
for (int i = 0; i < products.length(); i++) {
JSONObject c = products.getJSONObject(i);
// Storing each json item in variable
String name = c.getString(TAG_NAME);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_NAME, name);
al.add(name);
}
} else {
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String file_url) {
// dismiss the dialog after getting all products
pDialog.dismiss();
// updating UI from Background Thread
runOnUiThread(new Runnable() {
public void run() {
arrayAdapter = new ArrayAdapter<String>(MainActivity.this,
R.layout.item, R.id.tv_portal, al);
// set the listener and the adapter
flingContainer.setAdapter(arrayAdapter);
Toast.makeText(getApplicationContext(), "Done",
Toast.LENGTH_LONG).show();
}
});
}
}
It is not loading the data but it shows the toast done
.
I am using this - https://github.com/Diolor/Swipecards
How can I do this?
I also faced the same issue. Here's how I solved it. After this line
flingContainer.setAdapter(arrayAdapter);
Add this line
arrayAdapter.notifyDataSetChanged();
