Fragment layout
Activity Layout

Check if your #InjectViews has correct type. I've used ImageView instead of LinearLayout. That might be your problem too.

Android View Pager set Page within Fragment

I want to build a ViewPager with 2 Pages. On the first page you can choose a category. When a List item is selected the screen swipes to the second page and you can choose some subcategories.
I implemented the clicklistener and so on. But I have no idea how to set the current page from within a fragment. Is it even possible? Or do you have another solution for me? Hope you understand what I want to achieve.

Ok, found a solution for my own. Thanks to Sayem for the hint.
I passed the ID of the ViewPager via bundle to my first fragment. in my fragment i could use then this simple code:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
viewPagerId = getArguments().getInt("viewPagerId");
View rootView = (View) inflater.inflate(R.layout.fragment_cat, container, false);
populateListView(rootView);
viewPager = (ViewPager) getActivity().findViewById(viewPagerId);
return rootView;
}
and to switch pages then simply this:
viewPager.setCurrentItem(position);
Thanks for the help

use ((ActivityName)getActivity()).getViewPager().setCurrentItem(position);
note: getViewPager() should return the viewpager instance

try:
mPager.setCurrentItem(position);

How to set the right fragment to replace.

I’m doing a navigation drawer in my android app. On my onNavigationDrawerItemSelected function i try on item select to change the current fragment into a new one. The problem is that when I change the current fragment its take the initial status of it. maybe because i'm doing this way
fragmentManager.beginTransaction()
.replace(R.id.cont, new SessionsFragement())
.commit();
I declare a new instance of my fragment and i think it’s normal, its display me the initial status of the thing. On my fragment i've try to set a textView to see if i will say it when i call the fragement from tha navigation drawer but it's not the case.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_spot, container, false);
tata = (TextView) v.findViewById(R.id.tata);
tata.setText("karim");
return inflater.inflate(R.layout.fragment_spot, container, false);
}
So please can anyone help me to fix this.

In the snippet you posted you are inflating again the view. You should return the one you modified
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_spot, container, false);
tata = (TextView) v.findViewById(R.id.tata);
tata.setText("karim");
return v;
}

how to correctly load webview based on sample of creating swipe view

I am new and learning to create a webview by selecting a tab, based on google's sample at http://developer.android.com/training/implementing-navigation/lateral.html.
I created a class for webview fragment:
public static class WebViewFragment<rootView> extends Fragment {
WebView rootView;
public WebView onCreate(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
inflater.inflate(R.layout.fragment_webview_1, container,false);
rootView.getSettings().setJavaScriptEnabled(true);
rootView.loadUrl("http://www.google.com");
return rootView;
}
}
However, it runs without error but the webview interface never shows up. Appreciate if you can provide any clues.

Above method is actually not called by Android. It is a simple onCreate overloaded method.
Change that method to:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// would be safe to check class
rootView = (WebView)inflater.inflate(R.layout.fragment_webview_1, container,false);
rootView.getSettings().setJavaScriptEnabled(true);
rootView.loadUrl("http://www.google.com");
return rootView;
}

Using Fragments in ActionBar Tabs to have widgets

I made a program that uses FragmentTabs for implementing ActionBar Tabs.
I was wondering how it is possible to add a widget to a inflated Fragments in Tabs. It's more complicated than normal because the fragment is returning only an onCreateView to the TabListener, so how would I add in functioning widgets? I don't need specific code, just the logic please!
Here is a sample Fragment being inflated when a Tab is clicked (inside of which I need widgets):
public class IdFragment extends Fragment{
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
// Inflate the layout for this fragment
return inflater.inflate(R.layout.id_layout, container, false);
}
}
