this is my adapter class
I have a RecyclerView. Each row has a Download button, Cancale button, and Progressbar. when click on the Download button have to Download PDF from my phone storage and have to progress Progressbar The problem is when I scroll down the recyclerview the change item Id .means I can fit 1 items on the screen at once.then scroll ItemId change
I have a fragment where when a User inputs a link and hits the button, a service is initiated which processes the link and grabs image or videos if there are any on the url...
But my problem is that the same is downloaded more than once like 2 to 3 times..
here is the fragment -
public class FragmentTwo extends Fragment {

here's the Downloader Service -

if (ACTION_FOO.equals(action)) {

}
}
}
private void handleActionFoo(String urlStr) {
try {
ContentValues mediaInfo = new ContentValues();
Document doc = Jsoup.connect(urlStr).timeout(5000).get();
Document content = Jsoup.parse(doc.toString());
String videoUrl = content.getElementsByAttributeValue("property","og:video")
.attr("content");
String title = content.getElementsByAttributeValue("property","og:title")
.attr("content").replaceAll("[^a-zA-Z0-9\\u4E00-\\u9FA5\\s]","");
if (!videoUrl.isEmpty()) {
String videoName = title + ".mp4";
mediaInfo.put(Constants.MEDIA_NAME, videoName);
mediaInfo.put(Constants.MEDIA_URL, videoUrl);
} else {
String imgUrl = content.getElementsByAttributeValue("property","og:image").attr("content");
String imgName = title + ".jpg";
mediaInfo.put(Constants.MEDIA_NAME, imgName);
mediaInfo.put(Constants.MEDIA_URL, imgUrl);
}
Intent intent = new Intent(Constants.BROADCAST_ACTION);
intent.putExtra(Constants.MEDIA_INFO, mediaInfo);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
} catch (IOException e) {
e.printStackTrace();
}
}
}
& the Constants -
public final class Constants {
public static final String BROADCAST_ACTION = "com.parrotainment.media.downloader.BROADCAST";
public static final String MEDIA_INFO = "com.parrotainment.media.downloader.MEDIA_INFO";
public static final String MEDIA_NAME = "com.parrotainment.media.downloader.MEDIA_NAME";
public static final String MEDIA_URL = "com.parrotainment.media.downloader.MEDIA_URL";
}
just checking data in your oReceive may help. like this:
if(intent.getAction() != null && intent.getAction().equals("your_constant_item")){
//

In a list view i have image, text and image contains default image when list load with download complete , every thing works fine but when keyboard opens the downloaded image change to default image.

Try to tag the data model/ data source with your list view view.setTag(dataModel) in getView method of your adapter class.
Why not try RecyclerView instead of ListView and use Fresco Image Library?
I am new to android programming,I got a chance to work with (wifi printers).In my application I have a pdf file which needs to be taken a printout by using wifi printer
I didnt have much idea on this,but after doing a research I got that,there are 3 things to be done for doing this
1)getting the list of devices which are connected to wifi network which my mobile is using right now.
2) Then,select a device and make a connection with that device.
3) Transfer data to a printer
I hope these are the steps which I need to use.
I worked on first point,but I am getting the (Wifi networks like Tata communications,vonline etc) but not the devices which are connecting to that networks.
Here is the code I used.........
public class WiFiDemo extends Activity implements OnClickListener
{
WifiManager wifi;
ListView lv;
TextView textStatus;
Button buttonScan;
int size = 0;
List<ScanResult> results;
String ITEM_KEY = "key";
ArrayList<HashMap<String, String>> arraylist = new ArrayList<HashMap<String, String>>();
SimpleAdapter adapter;
/* Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// textStatus = (TextView) findViewById(R.id.textStatus);
buttonScan = (Button) findViewById(R.id.buttonScan);
buttonScan.setOnClickListener(this);
lv = (ListView)findViewById(R.id.list);
wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
if (wifi.isWifiEnabled() == false)
{
Toast.makeText(getApplicationContext(), "wifi is disabled..making it enabled", Toast.LENGTH_LONG).show();
wifi.setWifiEnabled(true);
}
this.adapter = new SimpleAdapter(WiFiDemo.this, arraylist, R.layout.row, new String[] { ITEM_KEY }, new int[] { R.id.list_value });
lv.setAdapter(this.adapter);
registerReceiver(new BroadcastReceiver()
{
#Override
public void onReceive(Context c, Intent intent)
{
results = wifi.getScanResults();
size = results.size();
}
}, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));
}
public void onClick(View view)
{
arraylist.clear();
wifi.startScan();
checkWifi();
Toast.makeText(this, "Scanning...." + size, Toast.LENGTH_SHORT).show();
try
{
size = size - 1;
while (size >= 0)
{
HashMap<String, String> item = new HashMap<String, String>();
item.put(ITEM_KEY, results.get(size).SSID + " " + results.get(size).capabilities);
arraylist.add(item);
size--;
adapter.notifyDataSetChanged();
}
}
catch (Exception e)
{ }
}
private void checkWifi(){
IntentFilter filter = new IntentFilter();
filter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
final WifiManager wifiManager =
(WifiManager)this.getSystemService(Context.WIFI_SERVICE);;
registerReceiver(new BroadcastReceiver(){
#Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
Log.d("wifi","Open Wifimanager");
String scanList = wifiManager.getScanResults().toString();
Log.d("wifi","Scan:"+scanList);
}
},filter);
wifiManager.startScan();
}
}
please suggest for the solution
Thanks in advance friends
Refer this Android-wifi-print - Github, Which contains a demo application I created for the same.
Edit :
As #NileshThakkar said. we may lost connection to that link in future so, I am posting code here.. with flow.
checks connectivity.
If connected in WiFi.. am storing that WiFi configuration.
Now checking whether I already have printer's information (WiFi configuration of WiFi printer) is available or not. If available, I'll scan and get list of WiFi ScanResults and connects to that else.. It'll showing list of WiFi and clicking on that, user will connect to printer and stores that WiFi configuration for future printing jobs.
After print job completes, I'm connecting to my previous WiFi or Mobile data connection.
Now going back to 2nd step.
If user connected in Mobile data, I'm just enabling WiFi and following 3rd step.
After Print job completes, I'm just disabling WiFi. so that, We'll be connected back to Mobile data connection. (That is android default).

I have made a program in which i am fetching list of all my Facebook Friends with their name, dob and profile picture, but i have decided to use tabs in my existing program therefore, i have also written code for that, but whenever i run my app, every time i am getting tabs but not getting list of friends..
In my case i am not getting FriendsList Activity data in TabSample Class, why?

Please tell me where i have to add this code :
Bundle extras = getIntent().getExtras();
String response = extras.getString("FRIENDS");
Log.d(LOG_TAG, "onCreate()" + response);
try {
jsonArray = new JSONArray(response);
} catch (JSONException e) {
FacebookUtility.displayMessageBox(this, this.getString(R.string.json_failed));
}
and any other code need to move from FriendsList class to TabSample Class
