Come call il dispositivo di scorrimento FrameLayout nelle attività di diffusione in Android

Ho 3 attività dicono first_activity , second_activity , third_activity . Ho usato FrameLayout per aprire un cursore.!

Ora quello che voglio aprire il cursore sul clic del button disponibile in tutte e tre le attività.

  • Tasto in ViewPager scorri alla pagina specifica
  • Taglia, copia, incolla in android
  • Visualizzazione di ProgressDialog durante l'avvio di un servizio
  • Ottenere il cursore corretto in CustomCursor Adapater getView ()
  • IBM Worklight - "Purtroppo HelloWorkLight si è arrestato" messaggio di errore
  • Come eliminare un argomento da Firebase Console? (FCM)
  • Così ora come nel Test 1 c'è un button sul lato sinistro allo stesso modo che ho su tutte e tre le attività in modo da clic su che voglio aprire il cursore.

    Questo è il mio codice di scorrimento

     public class MainActivity extends Activity { // Within which the entire activity is enclosed private DrawerLayout mDrawerLayout; // ListView represents Navigation Drawer private ListView mDrawerList; // ActionBarDrawerToggle indicates the presence of Navigation Drawer in the // action bar private ActionBarDrawerToggle mDrawerToggle; // Title of the action bar private String mTitle = ""; @SuppressLint("NewApi") @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTitle = "Test App"; getActionBar().setTitle(mTitle); // Getting reference to the DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); mDrawerList = (ListView) findViewById(R.id.drawer_list); // Getting reference to the ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close) { /** Called when drawer is closed */ public void onDrawerClosed(View view) { getActionBar().setTitle(mTitle); invalidateOptionsMenu(); } /** Called when a drawer is opened */ public void onDrawerOpened(View drawerView) { // getActionBar().setTitle("Approval Status"); invalidateOptionsMenu(); } }; // Setting DrawerToggle on DrawerLayout mDrawerLayout.setDrawerListener(mDrawerToggle); // Creating an ArrayAdapter to add items to the listview mDrawerList ArrayAdapter<String> adapter = new ArrayAdapter<String>( getBaseContext(), R.layout.drawer_list_item, getResources() .getStringArray(R.arrays.menus)); // Setting the adapter on mDrawerList mDrawerList.setAdapter(adapter); // Enabling Home button getActionBar().setHomeButtonEnabled(true); // Enabling Up navigation getActionBar().setDisplayHomeAsUpEnabled(true); // Setting item click listener for the listview mDrawerList mDrawerList.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // Getting an arrays of rivers String[] menuItems = getResources().getStringArray( R.arrays.menus); // Currently selected river mTitle = menuItems[position]; // Creating a fragment object // WebViewFragment rFragment = new WebViewFragment(); // // // Passing selected item information to fragment // Bundle data = new Bundle(); // data.putInt("position", position); // data.putString("url", getUrl(position)); // rFragment.setArguments(data); // // // // Getting reference to the FragmentManager // FragmentManager fragmentManager = getFragmentManager(); // // // Creating a fragment transaction // FragmentTransaction ft = fragmentManager.beginTransaction(); // // // Adding a fragment to the fragment transaction // ft.replace(R.id.content_frame, rFragment); // // // Committing the transaction // ft.commit(); // Closing the drawer mDrawerLayout.closeDrawer(mDrawerList); } }); } protected String getUrl(int position) { switch (position) { case 0: return ""; case 1: return ""; case 2: return ""; case 3: return ""; case 4: return ""; case 5: return ""; case 6: return ""; default: return ""; } } @Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); mDrawerToggle.syncState(); } @Override public boolean onOptionsItemSelected(MenuItem item) { if (mDrawerToggle.onOptionsItemSelected(item)) { return true; } return super.onOptionsItemSelected(item); } /** Called whenever we call invalidateOptionsMenu() */ @Override public boolean onPrepareOptionsMenu(Menu menu) { // If the drawer is open, hide action items related to the content view boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList); menu.findItem(R.id.action_settings).setVisible(!drawerOpen); return super.onPrepareOptionsMenu(menu); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.main, menu); return true; } }

    Non è ansible aprire un cassetto in un'altra attività a less che non disponga di un cassetto per tale attività.

    Ti suggerisco di utilizzare frammenti.

    Ancora prima di decidere sul tuo disegno ti suggerisco di dare un'occhiata a questo collegamento in primo luogo

    In oncreate

     if (savedInstanceState == null){ getUrl(0); } 

    In call getUrl(position)

    Poi in getUrl

      protected String getUrl(int position) { FragmentTransaction fragTran = getFragmentManager() .beginTransaction(); switch (position) { case 0: // make one a Fragment fragTran.replace(R.id.content_frame, fragment1); break; case 1: // second fragment fragTran.replace(R.id.content_frame, fragment2); break case 2: // third fragment fragTran.replace(R.id.content_frame, fragment3); break; } // Commit the transaction and close the drawer fragTran.commit(); mDrawerList.setItemChecked(position, true); mDrawerLayout.closeDrawer(drawerList); } 

    Esempio:

     public class Fragment1 extends Fragment { String[] titles={"A","B","C"}; @Override public View onCreateView( LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){ View rootView = inflater.inflate(R.layout.fragment1, container, false); return rootView; } }
