I have two activities. One displays all the notices in a listview and it displays links to pdf files. Second activity runs when an item is selected. Basically second activity should fire up on item click and it should open the pdf file.
Well the thing is that it does not fire up 2nd activity on item select. Posting the code for your reference.
CODE:
AllEventsActivity.java
public class AllEventsActivity extends ListActivity {
private ProgressDialog pDialog;
// Creating JSON Parser object
JSONParser jParser = new JSONParser();
ArrayList<HashMap<String, String>> productsList;
private static String url_all_products = "http://myurl/fetchnotice.php";
// JSON Node names
private static final String TAG_SUCCESS = "success";
private static final String TAG_PRODUCTS = "notices";
private static final String TAG_PID = "nid";
private static final String TAG_NAME = "notice";
private static final String TAG_INFO = "noticeinfo";
private static final String TAG_DATE = "date";
// products JSONArray
JSONArray products = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.all_events);
// Hashmap for ListView
productsList = new ArrayList<HashMap<String, String>>();
Button go_btn = (Button) findViewById(R.id.go_btn);
// Loading products in Background Thread
new LoadAllProducts().execute();
// Get listview
ListView lv = getListView();
// on seleting single product
// launching pdfviewer activity
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String pid = ((TextView) view.findViewById(R.id.einfo)).getText()
.toString();
// Starting new intent
Intent in = new Intent(getApplicationContext(),
PdfViewActivity.class);
// sending pid to next activity
in.putExtra("pathid", pid);
// starting new activity and expecting some response back
startActivityForResult(in, 100);
}
});
}
// Response from Edit Product Activity
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// if result code 100
if (resultCode == 100) {
// if result code 100 is received
// means user edited/deleted product
// reload this screen again
Intent intent = getIntent();
finish();
startActivity(intent);
}
}
class LoadAllProducts extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(AllEventsActivity.this);
pDialog.setMessage("Loading results. Please wait...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
protected String doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
// getting JSON string from URL
JSONObject json = jParser.makeHttpRequest(url_all_products, "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 id = c.getString(TAG_PID);
String name = c.getString(TAG_NAME);
String info = c.getString(TAG_INFO);
String date = c.getString(TAG_DATE);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_PID, id);
map.put(TAG_NAME, name);
map.put(TAG_INFO, info);
map.put(TAG_DATE, date);
// adding HashList to ArrayList
productsList.add(map);
}
} else {
// nothing found
}
} 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() {
/**
* Updating parsed JSON data into ListView
* */
ListAdapter adapter = new SimpleAdapter(
AllEventsActivity.this, productsList,
R.layout.list_item_eve, new String[] { TAG_PID,
TAG_NAME, TAG_INFO, TAG_DATE },
new int[] { R.id.eid, R.id.ename, R.id.einfo, R.id.date});
// updating listview
setListAdapter(adapter);
}
});
}
}
}
2nd Activity:
public class PdfViewActivity extends Activity {
private WebView webview;
//private ProgressDialog progressDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.photoview);
webview = (WebView) findViewById(R.id.my_img);
webview.getSettings().setBuiltInZoomControls(true);
webview.getSettings().setUseWideViewPort(true);
webview.getSettings().setDefaultZoom(WebSettings.ZoomDensity.FAR);
String id = getIntent().getExtras().getString("pathid");
webview.loadUrl("http://docs.google.com/viewer?url="+id);
}
}
