How to convert a main activity to a fragment in a Tabbed actionbar

[jonathan d roberts]

Hi all,

I am a noob with android at the moment so please bear with me.

I am currently building an app with action-bar tabs using fragments.  I have created four fragments with a mainactivity and I am trying to add a 5th fragment with a news feed in it.  Problem is I cannot find a news feed that will fit in a fragment.  I have tried the code below is there anyway I can get this to fit into a fragment.

IN the RSS activity I know I have to change it to extend fragment and I have tried changing the oncreate method to oncreate view, removed the setcontentview and added the rootviiew ectr.. and I have tried just using the RssFragment directly but when I do this nothing happens.

How can I get the RSs newfeeds to work within a fragment?.

My mainactivity

public class BradfordMain extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

        ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
        com.ff.kool4cats.myapplication.league1.BradfordMain.PagerAdapter pagerAdapter =
                new com.ff.kool4cats.myapplication.league1.BradfordMain.PagerAdapter(getSupportFragmentManager(),
                com.ff.kool4cats.myapplication.league1.BradfordMain.this);
        viewPager.setAdapter(pagerAdapter);

        TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
        tabLayout.setupWithViewPager(viewPager);

        for(int i = 0; i < tabLayout.getTabCount(); i++){
            TabLayout.Tab tab = tabLayout.getTabAt(i);
            tab.setCustomView(pagerAdapter.getTabView(i));
        }
    }

    @Override
    public void onResume() { super.onResume();}

    @Override
    public boolean onCreateOptionsMenu(Menu menu){

        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item){
        int id = item.getItemId();

        if(id == R.id.action_settings){
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    class PagerAdapter extends FragmentPagerAdapter {

        String tabTitles[] = new String[]{"Premiership", "Championship", "League One", "League Two"};
        Context context;

        public PagerAdapter(FragmentManager fm, Context context) {
            super(fm);
            this.context = context;
        }

        @Override
        public int getCount() {
            return tabTitles.length;
        }

        @Override
        public Fragment getItem(int position) {

            switch (position) {
                case 0:
                    return new BlankFragment();
                case 1:
                    return new BlankFragment();
                case 2:
                    return new BlankFragment();
                case 3:
                    return new Bradrss();
            }

            return null;
        }

        @Override
        public CharSequence getPageTitle(int position){
            return tabTitles[position];
        }

        public View getTabView(int position){
            View tab = LayoutInflater.from(com.ff.kool4cats.myapplication.league1.BradfordMain.this).inflate(R.layout.custom_tab, null);
            TextView tv = (TextView) tab.findViewById(R.id.custom_text);
            tv.setText(tabTitles[position]);
            return tab;
        }
    }
}

Rss MainActivity

public class Bradrss extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        if (savedInstanceState == null) {
            addRssFragment();
        }
    }

    private void addRssFragment() {
        FragmentManager manager = getSupportFragmentManager();
        FragmentTransaction transaction = manager.beginTransaction();
        RssFragment fragment = new RssFragment();
        transaction.add(R.id.fragment_container, fragment);
        transaction.commit();
    }
}

Rss Fragment

public class RssFragment extends Fragment implements OnItemClickListener {

    private ProgressBar progressBar;
    private ListView listView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_layout, container, false);
        progressBar = (ProgressBar) view.findViewById(R.id.progressBar);
        listView = (ListView) view.findViewById(R.id.listView);
        listView.setOnItemClickListener(this);
        return view;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        startService();
    }

    private void startService() {
        Intent intent = new Intent(getActivity(), RssService.class);
        getActivity().startService(intent);
    }

    /**
     * Once the {@link RssService} finishes its task, the result is sent to this BroadcastReceiver
     */
    private BroadcastReceiver resultReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            progressBar.setVisibility(View.GONE);
            List<RssItem> items = (List<RssItem>) intent.getSerializableExtra(RssService.ITEMS);
            if (items != null) {
                RssAdapter adapter = new RssAdapter(getActivity(), items);
                listView.setAdapter(adapter);
            } else {
                Toast.makeText(getActivity(), "An error occurred while downloading the rss feed.",
                        Toast.LENGTH_LONG).show();
            }
        }
    };

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        RssAdapter adapter = (RssAdapter) parent.getAdapter();
        RssItem item = (RssItem) adapter.getItem(position);
        Uri uri = Uri.parse(item.getLink());
        Intent intent = new Intent(Intent.ACTION_VIEW, uri);
        startActivity(intent);
    }

    @Override
    public void onStart() {
        super.onStart();
        IntentFilter intentFilter = new IntentFilter(RssService.ACTION_RSS_PARSED);
        LocalBroadcastManager.getInstance(getActivity()).registerReceiver(resultReceiver, intentFilter);
    }

    @Override
    public void onStop() {
        super.onStop();
        LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(resultReceiver);
    }
}
