How to work with ids and strings in pagerTabStrip - string

Question

Super newbie question about accessing information in strings. I have chunked together an app that uses a fragmentpager and the PagerTabStrip.
It is supposed to display titles on the tab, but mine displays nothing...because I am a total newbie hacking his way through. I am so grateful for this community.
From my layout file that calls the content (and once I fix it the title--id#pager_header right?):
<android.support.v4.view.PagerTabStrip
android:id="#+id/pager_header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:paddingBottom="4dp"
android:paddingTop="4dp"
android:textColor="#ffffff" />
My code that gets me the swipeable pages of content:
public class Poems extends FragmentActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contentpage);
/** Getting a reference to the ViewPager defined the layout file */
ViewPager pager = (ViewPager) findViewById(R.id.pager);
/** Getting fragment manager */
FragmentManager fm = getSupportFragmentManager();
/** Instantiating FragmentPagerAdapter */
MyFragmentPagerAdapter pagerAdapter = new MyFragmentPagerAdapter(fm);
/** Setting the pagerAdapter to the pager object */
pager.setAdapter(pagerAdapter);
}
}
My code that should get me the titles from the string reference file.
public class MyFragment extends Fragment{
int mCurrentPage;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/** Getting the arguments to the Bundle object */
Bundle data = getArguments();
/** Getting integer data of the key current_page from the bundle */
mCurrentPage = data.getInt("current_page", 0);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.myfragment_layout, container,false);
TextView tv = (TextView ) v.findViewById(R.id.tv);
tv.setMovementMethod(new ScrollingMovementMethod());
switch(mCurrentPage){
case 0:
tv.setText(" ");
break;
case 1:
tv.setText(R.string.content_1);
break;
case 2:
tv.setText(R.string.content_2);
break;
case 3:
tv.setText(R.string.content_3);
break;
}
return tv;
}
}
How do I get pager_header from this?
A sample relevant string is:
<string name="content_1">Welcome to this app!</string>
I am thinking that I need to better understand strings since I'm coming from more of a text content background.
How do I include in the stings.xml file the indicators that allow the app to reference the content associated with pageview so that I can have that show up in the tab? How I do make it so that the content shows "Welcome to this app" but the title in the tab shows "Home"?
I think as if each entry (page) is like a line in a database with one point of reference being the title, one being the content, one being a link or some other content. Each has its own id, right?
Thank you in advance for explaining this to a beginner.

You need to implement getPageTitle(int position) in MyFragmentPagerAdapter. The String that is returned from this method is used to set the title of the PagerTabStrip.
#Override
public CharSequence getPageTitle(int position) {
Log.v(TAG, "getPageTitle");
String tabTitle;
switch(position) {
case 0:
tabTitle = "Tab #0";
break;
case 1:
tabTitle = "Home";
break;
case 2:
tabTitle = "Tab #2";
break;
case 3:
tabTitle = "Tab #3";
break;
default:
tabTitle = "Default Tab Title";
break;
}
return tabTitle;
}
You can make this more dynamic by making the title and content arguments that you pass in using a Bundle by calling setArguments(Bundle args) on your MyFragments that you add to your ViewPager. In MyFragment in onCreateView() you can then set your content based on the passed in content String argument. Then in MyFragmentPagerAdapter you can get a reference to the Fragment at the position and pull get the title directly from MyFragment.
