Progress circle not running till it loads RecyclerView

I am trying to move from one activity A to another activity B.In activity B there is a recycler view,In that recycler view I am loading data in background thread(Using AsyncTask) from SQLite database.When I switch to activity B I have given a Progress Bar to show the loading of data.But that progress bar doesn't spin till it fully loads the data.I want it to spin to show loading is happening.
This some what looks like this,
When loading happens then it starts to spin,and looks like this.Running behind the recycler view.

How to fix setOnItemClickListener inside ListView

I have a ListView which has more rows in it. Inside of rows I have two LinearLayouts (deleteItem and editItem) which has setOnClickListener on them. When I'm trying to click on deleteItem or editItem it works only at the second touch, i don't know why.. I've read some answers on stackoverflow but I couldn't find one answer to fix my problem..
This is the code:

}

Your problem might be caused by the way your program executes. You first thread your adapter initialization, and then your main thread starts attaching onclick listeners before your adapter initialization finishes. This means your listview will have a click listener but not the items in the adapter, and when you click the listview once
new GetMyCurrencyResults().execute(new MyCurrencyConnector());
this fires off in your DeleteCurrencyTask and sets the adapter again. To fix this try putting setOnClick initializaion in the post execute of your
private class GetMyCurrencyResults extends AsyncTask<MyCurrencyConnector,Void,JSONArray>{

I believe I realized why the event of deleteItem and editItem is called only on second click, because deleteItem and editItem clickListeners are atached only when getAllMyCurrencyListView.setOnItemClickListener (when I click on row) is called not when the code is loaded. So I guess I have to find another way to make these events

Listview not displaying the right image in android

In my app I have a listview. Each listview item contains an image view and several textviews. To display the image I use Drawable. But the images are displayed in the wrong row when scrolling. The image in a row changes several times until the right image appears. I have searched the web but I found nothing working for me. I am posting my code below. Please help me! Thanks in advance!

Try this..
You have to use ViewHolder for that issue
private class ViewHolder {
ImageView iconImg;
TextView kompaniaTxt,pozicioniTxt,kategoriaTxt,qytetiTxt;
}
EDIT
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
final ViewHolder holder;
if (convertView == null) {
view = getActivity().getLayoutInflater().inflate(R.layout.row_site, parent, false);
holder = new ViewHolder();
holder.iconImg = (ImageView) view.findViewById(R.id.iconImg);
holder.kompaniaTxt = (TextView) view.findViewById(R.id.nameTxt);
holder.pozicioniTxt = (TextView) view.findViewById(R.id.aboutTxt);
//holder.kategoriaTxt = (TextView) view.findViewById(R.id.kategoriaTxt);
holder.qytetiTxt = (TextView) view.findViewById(R.id.qytetiTxt);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
holder.kompaniaTxt.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//String emri_komp=kompaniaTxt.getText().toString().replaceAll("\\s+","%20");
String emri_komp=holder.kompaniaTxt.getText().toString();
Intent intent=new Intent(c,CompanyDesc.class);
intent.putExtra("emri_komp", emri_komp);
intent.putExtra("url1", url1);
c.startActivity(intent);
}
});
holder.kategoriaTxt.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
String idKateg=getItem(posi).getIdKategoria();
Intent intent=new Intent(c,CategoryList.class);
intent.putExtra("idKateg", idKateg);
intent.putExtra("url2", url2);
c.startActivity(intent);
}
});
//Set the relavent text in our TextViews
holder.kompaniaTxt.setText(getItem(pos).getKompania());
holder.pozicioniTxt.setText(getItem(pos).getPozicioni());
holder.kategoriaTxt.setText(getItem(pos).getKategoria());
holder.qytetiTxt.setText(getItem(pos).getQyteti());
url1=getItem(pos).getImgUrl();
SitesDownloadTask download=new SitesDownloadTask();
download.execute();
return view;
}
and onPostExecute
#Override
protected void onPostExecute(Void result){
holder.iconImg.setBackground(backgr);
}
EDIT
Instead of using SitesDownloadTask AsyncTask use Universal Image Loader lib

Android - Pull to refresh within a tabbed fragment

I'm trying to make a refresh while sliding down on the top of the listview possible. I followed this link to make it work and it does on an activty. But I need it on fragments that are tabbed within a main activity so I cannot as the example shows use this method on my fragments.
Here's the correct code while using an activity:
TestActivity.java
import java.util.ArrayList;
import java.util.List;
import uk.co.senab.actionbarpulltorefresh.library.ActionBarPullToRefresh;
import uk.co.senab.actionbarpulltorefresh.library.PullToRefreshLayout;
import uk.co.senab.actionbarpulltorefresh.library.listeners.OnRefreshListener;
import android.os.AsyncTask;
import android.os.Bundle;
import android.app.Fragment;
import android.app.ListFragment;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
public class TestActivity extends BaseActivity {
#Override
protected Fragment getSampleFragment() {
return new SimpleListFragment();
}
public static class SimpleListFragment extends ListFragment implements
OnRefreshListener {
int i = 0;
private PullToRefreshLayout mPullToRefreshLayout;
ArrayAdapter<String> adapter;
List<String> list;
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onViewCreated(view, savedInstanceState);
list = new ArrayList<String>();
int no = 1;
for (int i = 0; i < 5; i++) {
list.add("Item No :" + no++);
}
super.onViewCreated(view, savedInstanceState);
ViewGroup viewGroup = (ViewGroup) view;
// As we're using a ListFragment we create a PullToRefreshLayout
// manually
mPullToRefreshLayout = new PullToRefreshLayout(
viewGroup.getContext());
// We can now setup the PullToRefreshLayout
ActionBarPullToRefresh
.from(getActivity())
// We need to insert the PullToRefreshLayout into the
// Fragment's ViewGroup
.insertLayoutInto(viewGroup)
// Here we mark just the ListView and it's Empty View as
// pullable
.theseChildrenArePullable(android.R.id.list,
android.R.id.empty).listener(this)
.setup(mPullToRefreshLayout);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, list);
// Set the List Adapter to display the sample items
setListAdapter(adapter);
setListShownNoAnimation(true);
}
#Override
public void onRefreshStarted(View view) {
// TODO Auto-generated method stub
// setListShown(false); // This will hide the listview and visible a
// round progress bar
new AsyncTask<Void, Void, Void>() {
#Override
protected Void doInBackground(Void... params) {
try {
Thread.sleep(5000); // 5 seconds
int itemNo = list.size();
itemNo++;
list.add("New Item No :" + itemNo);
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
adapter.notifyDataSetChanged();
// Notify PullToRefreshLayout that the refresh has finished
mPullToRefreshLayout.setRefreshComplete();
// if you set the "setListShown(false)" then you have to
// uncomment the below code segment
// if (getView() != null) {
// // Show the list again
// setListShown(true);
// }
}
}.execute();
}
}
}
I've already tried multiple times to make this method work in my fragment code but I cannot succeed. The code below is a working fragment example without any input of the TestActivity.
InfoFragment.java
import java.util.ArrayList;
import java.util.List;
import com.example.app.Config;
...
import android.app.Activity;
import android.os.Bundle;
import android.provider.Settings.Secure;

import android.widget.AdapterView;
import android.widget.ListView;
public class TicketInfoFragment extends Fragment {
List<Info> ticketInfo;
TicketFull ticket = new TicketFull();
private DatabaseHelper db;
int ticketId = TicketActivity.getCurrentTicketId();
String androidId;
String authCode;
String platform_url;
int uId;
View rootView;
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
db = new DatabaseHelper(getActivity());
androidId = Secure.getString(getActivity().getContentResolver(),
Secure.ANDROID_ID);
Config config = new Config();
config = db.getConfig(androidId);
authCode = config.getAuthCode();
platform_url = config.getPlatformURL();
uId = config.getuId();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_ticket_information, container, false);
fillTicket();
return rootView;
}
private void fillTicket() {
HttpReader httpReader = new HttpReader();
httpReader
.setOnResultReadyListener(new HttpReader.OnResultReadyListener() {
#Override
public void resultReady(String result) {
JsonHelper jsonHelper = new JsonHelper();
ticket = jsonHelper.getTicket(result);
//showTicket();
fillSettings();
}
});
httpReader
.execute("http://aa.domainlink.com:1324/example/API/v1/json.php?auth=example&a=ticket&uauth="
+ authCode + "&uid=" + uId + "&id=" + ticketId);
}
private void readSettings() {
InfoAdapter infoAdapter = new InfoAdapter(
getActivity(), ticketInfo);
final ListView listViewInfo = (ListView) rootView.findViewById(R.id.listViewInfo);
listViewInfo.setAdapter(infoAdapter);
listViewInfo
.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parentView,
View childView, int position, long id) {
}
});
listViewInfo.setEmptyView(rootView.findViewById(R.id.empty));
}
private void fillSettings() {
String dueDate = getString(R.string.noDueDate);
ticketInfo = new ArrayList<Info>();
ticketInfo.add(new Info(getString(R.string.ticket_subject), ticket.getSubject() + ""));
ticketInfo.add(new Info(getString(R.string.ticket_relation), ticket.getRelation() + ""));
ticketInfo.add(new Info(getString(R.string.ticket_status), ticket.getStatus() + ""));
ticketInfo.add(new Info(getString(R.string.ticket_priority), ticket.getPriority() + ""));
ticketInfo.add(new Info(getString(R.string.ticket_created), ticket.getTicketCreate() + ""));
ticketInfo.add(new Info(getString(R.string.ticket_department), ticket.getDepartmentName() + ""));
ticketInfo.add(new Info(getString(R.string.ticket_user), ticket.getUser() + ""));
if (!ticket.getDueDate().equals("00-00-0000 00:00:00")) {
dueDate = ticket.getDueDate();
}
ticketInfo.add(new Info(getString(R.string.ticket_dueDate), dueDate));
readSettings();
}
}
The BaseActivity that the activity normally requires:
BaseActivity.java
import android.app.Activity;
import android.app.Fragment;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
public class BaseActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
// Add the Sample Fragment if there is one
Fragment sampleFragment = getSampleFragment();
if (sampleFragment != null) {
getFragmentManager().beginTransaction()
.replace(android.R.id.content, sampleFragment).commit();
}
}
//This method will override by child class. Then base class can get the fragment
protected Fragment getSampleFragment() {
return null;
}
}
Posting my failed tries on implementing the activity method in my fragments would not work I guess so I do not post them.
If anyone of you could help thanks alot.

Android SDK has finally added SwipeRefreshLayout. Maybe you can add this to your layout?

OnListItemClick in an activity

In my Android app I have a list of countries that I can add new entries to at any time when the app is running. This list is held in a database. I have tried several different ways of trying to implement an OnListItemClick but I cannot get it to work. Here is my class containing my list:

Here is my class where I can choose to enter new countries into the list:
import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import android.widget.Toast;
public class EditList extends Activity
{
private DBManager db;
Cursor cursor;
EditText editCountry, editYear, editDesc;
Button add, delete, back;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editCountry = (EditText)findViewById(R.id.editcountry);
editYear = (EditText)findViewById(R.id.edityear);
editDesc = (EditText)findViewById(R.id.editdesc);
add = (Button)findViewById(R.id.add);
delete = (Button)findViewById(R.id.delete);
back = (Button)findViewById(R.id.backmain);
//Open database and fill it with content, then close it

add.setOnClickListener(buttonAddOnClickListener);

//handle switching back to main screen
Log.i("Test", "back to main");
back = (Button)findViewById(R.id.backmain);
back.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
db.close();
//can't use "finish()" because then the list won't refresh with the new data

updateList();
//clear text fields after use

I have previously implemented an OnListItemClick in a class where the data was statically held in an array. That class also extended ListActivity, which this one doesn't.

The difference between ListActivity and a standard Activity is that the ListActivity handled the OnItemClickListener interface mapping for you, and just provided an extra callback method. Without ListActivity, you'll need to add that plumbing yourself; i.e.
public class MainActivity extends Activity implements AdapterView.OnItemClickListener
{
...
ListView listContent;
#Override
public void onCreate(Bundle savedInstanceState)
{
...
listContent.setOnItemClickListener(this);
...
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
//Callback logic here for clicked items
}
...
}

In your MainActivity add
#Override
public void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
// a list item is click do whatever you want
}
