POAndroid: "Navigation Type: Fixed Tabs + Swipe"
text
Body
copied!<p>I'm trying to use Tabs + Swipe in an App and want to use the Navigation Type "Fixed Tabs + Swipe" which the ADT provides me when creating an Activity.</p> <p>Sooo now the ADT spits out nice Code, which I slightly modified...</p> <p>I completely understand the code and what's going on... But how can I teach the App to use my three Fragments instead of the stupid Dummy Frag? :(</p> <p>I cannot find any tutorial which deals with the ADTs "Navigation Types"...</p> <p>Thanks for your help!</p> <pre><code>public class MainActivity extends FragmentActivity implements ActionBar.TabListener { SectionsPagerAdapter mSectionsPagerAdapter; ViewPager mViewPager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Set up the action bar. final ActionBar actionBar = getActionBar(); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); // Create the adapter that will return a fragment for each of the three // primary sections of the app. mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager()); // Set up the ViewPager with the sections adapter. mViewPager = (ViewPager) findViewById(R.id.pager); mViewPager.setAdapter(mSectionsPagerAdapter); // When swiping between different sections, select the corresponding // tab. We can also use ActionBar.Tab#select() to do this if we have // a reference to the Tab. mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() { @Override public void onPageSelected(int position) { actionBar.setSelectedNavigationItem(position); } }); //Adding Tabs actionBar.addTab(actionBar.newTab().setText("Tab 1").setTabListener(this)); actionBar.addTab(actionBar.newTab().setText("Tab 2").setTabListener(this)); actionBar.addTab(actionBar.newTab().setText("Tab 3").setTabListener(this)); } @Override public void onTabSelected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) { // When the given tab is selected, switch to the corresponding page in // the ViewPager. mViewPager.setCurrentItem(tab.getPosition()); } @Override public void onTabUnselected(ActionBar.Tab tab,FragmentTransaction fragmentTransaction) { } @Override public void onTabReselected(ActionBar.Tab tab,FragmentTransaction fragmentTransaction) { } public class SectionsPagerAdapter extends FragmentPagerAdapter { public SectionsPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { // getItem is called to instantiate the fragment for the given page. // Return a DummySectionFragment (defined as a static inner class // below) with the page number as its lone argument. Fragment fragment = new DummySectionFragment(); Bundle args = new Bundle(); args.putInt(DummySectionFragment.ARG_SECTION_NUMBER, position + 1); fragment.setArguments(args); return fragment; } @Override public int getCount() { // Show 3 total pages. return 3; } } public static class DummySectionFragment extends Fragment { /** * The fragment argument representing the section number for this * fragment. */ public static final String ARG_SECTION_NUMBER = "section_number"; public DummySectionFragment() { } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_main_dummy,container, false); TextView dummyTextView = (TextView) rootView.findViewById(R.id.section_label); dummyTextView.setText(Integer.toString(getArguments().getInt(ARG_SECTION_NUMBER))); return rootView; } } } </code></pre>
