I have multiple fragments in my Activity. It should initiate only first fragment at start up. It initializes the second one also. More over I move from one fragment to the other though a swipe action. When I swipe from first fragment to the next, third in the row is also initiated.
I have to get data from the server and then populate that fragment. Network request is sent but not for the one for which I am sending but for the fragment next to it.
Please suggest me where I am mistaken...
Thanks in advance.
Following is the code:
Note: Sample code is being used, Please consider the other fragments and their layouts as the same as that for Fragment1.

I achieved it by placing the following code at the end of OnPageChangeListener.onPageSelected()
Fragment fragment = _adapter.getFragment(previousFragment);
if(fragment != null) {
fragment.onPause();
}
I am using onPause() in the following way
public void onPause(){
super.onPause();
onDestroyView();
}
public void onDestroyView() {
super.onDestroyView();
onDestroy();
}
public void onDestroy() {
super.onDestroy();
onDetach();
}
public void onDetach() {
super.onDetach();
}
this is a known issue, that ViewPager(FragmentAdapter(Fragements)) created and destroyed according to the actual page.
I also came across with this situation, furthermore the data (Object) not referenced, because of a destroy will be collected by the GC so this is difficult.
I would use a static object at the main Activity and with the onRetainNonConfigurationInstance method I would save and load Fragment state.
Also found another solution which concentrated on the passed data between the Fragments (A,B and passed String data) here.
I hope one of these solutions are suitable for you!
Just call setOffscreenPageLimit() in onCreate() (after initializing ViewPager). The OffscreenPageLimit sets the number of pages that should be retained to either side of the current page. Set the minimum number of fragments you want to initiate either side.

I wanted to achieve this animation, which is the search edit box overlays the tab-layout, I must tell that I tried this code on the parent layout android:animateLayoutChanges="true" and set the tab-layout visibility to View.GONE but it just animates the tab moving up, not the search box overlays tab-layout.
I have made a quick dummy app that looks like yours, and tried to achieve what you have shown in your animation. See the effect below (you can make it more smooth and elegant) :
Its a bit tricky way of doing, the way I have done. I post my whole code here :

[![enter image description here][2]][2]
But i want the images to come like a stack.. Not exactly overlapped. Refer this
Can anyone help me achieve this?
This is a link with your solution https://github.com/Diolor/Swipecards
Incase you use custom ArrayAdaper on inflating layout this is the code that worked for me
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.swipe_item, parent, false);

I am extending NavigationDrawer in my other activities(MainActivity and Login).
I want MainActivity and Login to have navigation drawer as well as their own xml views/xml files. If I put some content in navigation_drawer.xml, then it would come in all activities. I want different contents for MainActivity and Login with same navigation drawer.
Thank you.

Each Activity has to have his one fragment layout and inflate it from there. Take a look at this tutorial, it's really good:
I created my app with the Tabbed Activity. I created some fragments and simple UI. Swipe and tabs work. I want to make really simple calculator-like app but I can't even change the text.
I tried so many solutions found on the Internet, but nothing works. I'm a beginner in Android development and now my code is a real mess.
What change to make it work? I just want to change some TextView's texts after clicking calculate button.

Inside onCreateView() of the fragment :
Button calculate = (Button) convertView.findViewById(R.id.calculate);
final TextView textView = (TextView) convertView.findViewById(R.id.textViewId);
Then set a click listener on the button. :
calculate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
textView.setText("Here goes sample text");
}
});
I just want to know if this is possible since first. I have created a custom listView based on the tutorial I read from Sai Geetha. Well it works perfectly on my app except that it needs to extend ListActivity instead of FragmentActivity. Now I'm having a hard time configuring and adding a dialog for this since I need to apply a fragment dialog and I can't use the getFragmentManager() since I'm not working with the FragmentActivity. Is there's another way I can do to work on this without sacrificing the ListActivity? Thanks!
Here's my code so far

You can use ListFragment inside FragmentActivity instead of using a ListActivity.
