getItem function calling twice in FragmentStatePagerAdapter?

I Have a problem with getItem() function why because it is called twice in FragmentStatePagerAdapter class.
Actually the main reason is in application having TextoSpeech functionality so getItem() function twice the text also speech twice. This is my code can u please assist me....Great thanks in advance.
Here is the code
This is MainActivity class:
public class MainActivity extends FragmentActivity{
PagerFragment pagerFragment;
Cursor mCursor;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.rhymes_activity_main);
DBUtils utils = new DBUtils(getApplicationContext());
new DBUtils(getApplicationContext());
try {
DBUtils.createDatabase();
} catch (IOException e) {
Log.w(" Create Db "+e.toString(),"===");
}
DBUtils.openDatabase();
mCursor = utils.getResult("select * from Cflviewpagerdata order by title");
final ArrayList<PageData> myList = new ArrayList<PageData>();
while (mCursor.moveToNext()) {
myList.add(new PageData(mCursor.getInt(
mCursor.getColumnIndex("_id")),
mCursor.getString(mCursor.getColumnIndex("title")),
mCursor.getString(mCursor.getColumnIndex("view"))));
}
mCursor.close();
ListView lv = (ListView) findViewById(R.id.list_view);
ListViewAdapter lva = new ListViewAdapter(this, R.layout.list_item, myList);
lv.setAdapter(lva);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//peace of code that create launch new fragment with swipe view inside
PagerFragment pagerFragment = new PagerFragment();
Bundle bundle = new Bundle();
bundle.putInt("CURRENT_POSITION", position);
bundle.putParcelableArrayList("DATA_LIST", myList);
pagerFragment.setArguments(bundle);
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction ft = fragmentManager.beginTransaction();
ft.replace(R.id.container, pagerFragment, "swipe_view_fragment").commit();
}
});
DBUtils.closeDataBase();
}
#Override
public void onBackPressed() {
FragmentManager fm = getSupportFragmentManager();
Fragment f = fm.findFragmentByTag("swipe_view_fragment");
if(f!=null){
fm.beginTransaction().remove(f).commit();
}else{
super.onBackPressed();
}
}
}
This is PagerFragment class:
public class PagerFragment extends Fragment{
private ArrayList<PageData> data;
private int currentPosition;
private String mTitle;
private FragmentActivity context;
#Override public void onAttach(Activity activity) {
context = (FragmentActivity) activity;
super.onAttach(activity);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_pager, container, false);
ViewPager mViewPager = (ViewPager) v.findViewById(R.id.pager_view);
currentPosition = getArguments().getInt("CURRENT_POSITION");
mTitle = getArguments().getString("T_TITLE");
data = getArguments().getParcelableArrayList("DATA_LIST");
FragmentItemPagerAdapter fragmentItemPagerAdapter = new FragmentItemPagerAdapter(getFragmentManager(), data);
mViewPager.setAdapter(fragmentItemPagerAdapter);
mViewPager.setCurrentItem(currentPosition);
return v;
}
}
This is FragmentItemPagerAdapter class:
public class FragmentItemPagerAdapter extends FragmentStatePagerAdapter{
private static ArrayList<PageData> data;
public FragmentItemPagerAdapter(FragmentManager fm, ArrayList<PageData> data){
super(fm);
this.data = data;
}
#Override
public Fragment getItem(int position) {
Fragment fragment = new PageFragment();
Bundle args = new Bundle();
args.putString(PageFragment.TITLE, data.get(position).getTitle());
args.putString(PageFragment.DESCRIPTION, data.get(position).getDes());
args.putInt("CURRENT_POSITION", position);
fragment.setArguments(args);
return fragment;
}
void deletePage(int position) {
if (canDelete()) {
data.remove(position);
notifyDataSetChanged();
}
}
boolean canDelete() {
return data.size() > 0;
}
#Override
public int getItemPosition(Object object) {
// refresh all fragments when data set changed
return PagerAdapter.POSITION_NONE;
}
#Override
public int getCount() {
return data.size();
}
public static class PageFragment extends Fragment implements OnInitListener{
public static final String TITLE = "title";
public static final String DESCRIPTION = "view";
String om;
TextToSpeech tts;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_item, container, false);
((TextView) rootView.findViewById(R.id.item_label)).setText(getArguments().getString(TITLE));
View tv = rootView.findViewById(R.id.item_des);
((TextView) tv).setText(getArguments().getString(DESCRIPTION));
Bundle bundle = getArguments();
int currentPosition = bundle.getInt("CURRENT_POSITION");
tts = new TextToSpeech( getActivity(), PageFragment.this);
om = data.get(currentPosition).getDes();
tts.speak(om, TextToSpeech.QUEUE_FLUSH, null);
return rootView;
}
#Override
public void onDestroy() {
if (tts != null) {
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
public void onInit(int status) {
// TODO Auto-generated method stub
if (status == TextToSpeech.SUCCESS) {
tts.speak(om, TextToSpeech.QUEUE_FLUSH, null);
}
}
}
}
This is PageData class:
This class is Object class
public class PageData implements Parcelable{
private String title;
private String view;
public PageData(){
}
public PageData(Parcel in){
title = in.readString();
view = in.readString();
}
public int describeContents() {
return 0;
}
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(title);
dest.writeString(view);
}
public PageData(int picture, String title, String description){
this.title = title;
this.view = description;
}
public String getTitle() {
return title;
}
public String getDes() {
return view;
}
}
This is Xml code

This images are my application look
This image is logcat of my application
Highlighted is my problem.
This is my code can you please help me any one.
I am new one of Android so please help

FragmentStatePagerAdapter preloads always at least 1 page.
You can try to use setUserVisibleHint to handle your logic only for visible fragment:
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (isVisibleToUser) {
// Your code
}
}

Don't initialize songAdapter1 again inside loadSongs().
Create a method like this in songAdapter class:
public void notifySongAdded(ArrayList<songInfo> songs) {
this.songs = songs;
notifyDataSetChanged();
}
And call songAdapter1.notifySongAdded(songs); after adding songs inside loadSongs().

Navigation drawer stuck when offline data loading

I am developing news app user can download video and image.
So I developed navigation drawer with different fragment with material design. But I am facing some problem in it when I click gallery (where I show the downloaded video and images) it stuck for some time and then open fragment. it happened only in specific fragment but not all.

In your AsyncTask, you are accessing the class fields of the Fragment! This will actually block the UI Thread :-(
The lines
videofiles = new ArrayList<>();
imagefiles = new ArrayList<>();
cannot be there. You need to create local lists, put data in them and then return it in onPostExecute().
Start by replacing
public class LoadOfflineData extends AsyncTask<Void, Void, Void> {
with
public static class LoadOfflineData extends AsyncTask<Void, Void, Void> {
This will give you errors in places you need to change :-)

I found the answer.
It is in my RecyclerAdapter when i get thumbnail using inbuilt class so it will take time to set it see my
Old code
Bitmap bmThumbnail;
//MICRO_KIND, size: 96 x 96 thumbnail
bmThumbnail = ThumbnailUtils.createVideoThumbnail(sdcard_path + "/Botad News/Videos/" + fileName, MediaStore.Images.Thumbnails.MICRO_KIND);
holder.img_main.setImageBitmap(bmThumbnail);
New code is using glide library so lib automatically handle the thread i assume.
BitmapPool bitmapPool = Glide.get(context).getBitmapPool();
int microSecond = 6000000;// 6th second as an example
VideoBitmapDecoder videoBitmapDecoder = new VideoBitmapDecoder(microSecond);
FileDescriptorBitmapDecoder fileDescriptorBitmapDecoder = new FileDescriptorBitmapDecoder(videoBitmapDecoder, bitmapPool, DecodeFormat.PREFER_ARGB_8888);
Glide.with(context)
.load(sdcard_path + "/Botad News/Videos/" + fileName)
.asBitmap()
.override(250,250)// Example
.videoDecoder(fileDescriptorBitmapDecoder)
.into(holder.img_main);
Found solution HERE....

Fragment: Get object from activity (Tab View)

how can I can access in this example the object "selectedBox" from the fragment? I need it in the main activity for testing connection and in the fragment.
In the moment I create it in the main and the fragment.

You need to create an interface to your activity from your fragment. Something like:
public class MainActivity extends FragmentActivity implements ActionBar.TabListener,MainFragment.getSelectedBox {
private ViewPager viewPager;
private ActionBar actionBar;
private MainTabAdapter mAdapter;
private String[] tabs = { "Live" };
private box selectedBox;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
....
}
//called from the MainFragment
#Override
public void AccessSelectedBox {
this.box = <do something with box>
}
}
Fragment Class
public class MainFragment extends ListFragment {
//interface to the MainActivity activity class
private getSelectedBox listener;
public interface getSelectedBox {
public void AccessSelectedBox();
}
}
Here is a good article on this: http://www.vogella.com/articles/AndroidFragments/article.html.

Setting OnClick to ViewPager not functioning

I am having some trouble with implementing OnItemClick to the ViewPager.
I would like it so when I click on one of my picture's being displayed by the ViewPager, it displays a toast message just to tell me that this is working.
So far, nothing happens when I click on one of my items when doing this.
Any help would be appreciated!
