Dynamically create tab in android and load fragment with parameters passed in it

Question

I want to create tabs dynamically on the basis of count of websites given in an array. On each click of tab I want to load a fragment with webview with website loaded in it by passing corresponding url of website from array. Can I implement pager in it too?

Thanks

I had posted a help request previously with my code at, or may be I was not able to define my problem there: Dynamically adding tabs in android with webview and fragment

Answer 1

Try this i ve done this long ago maybe few bugs but still:

Create arraylist of fragments and urls in mainactivity:

 ArrayList<Fragment> fragments = new ArrayList<>();
 ArrayList<String> urls =  new ArrayList<>();

Now while u iterate through ur dynamic data keep adding:

 while(iterator.hasNext()) {
fragments.add(new ftab1());
urls.add(url);
}

Now setup adapter passing above two arraylist:

PagerAdapter pageradapter= new PagerAdapter(getSupportFragmentManager(),getApplicationContext(),fragments,urls);
  pager.setAdapter(pageradapter);

Now coming to PagerAdapter: Create two global variables

ArrayList<Fragment> fragments;
    ArrayList<String> urls;

Define constructor and initialise the above 2 variables:

 public PagerAdapter(FragmentManager fm, Context context, ArrayList<Fragment> fragments,ArrayList<String> urls) {
        super(fm);
        this.context = context;
        this.fragments = fragments;
        this.urls=urls;
    }

Now main function is getItem() pass data in bundle to that activity:

 @Override
    public Fragment getItem(int i) {
        Bundle data = new Bundle();
        data.putString("url",urls.get(i));
        fragments.get(i).setArguments(data);
        return fragments.get(i);
    }

Now get url in your ftab1 like this:

String url = getArguments().getString("url");
