Body
copied!<p>I'm having a difficulty to show a fragment in a container when a menu item is clicked.Below is my code.</p> <p>I tried to do <code>ft.show();</code> inside onMenuItemClick of Login Menu Item but its not working and I don't know what am I doing wrong as I'm neither getting any errors nor the app is crashing. Fragments which are attached to the Tabs are working and displaying just fine. It's just that when I try to load a fragment in an container when menu item is clicked at that time nothing happens.Please point me in a right direction and lemme know what am I doing wrong.</p> <pre><code>public class HomeActivity extends SherlockFragmentActivity { public SherlockFragment fragment; FragmentTransaction ft; public static Context appContext; ActionBar actionbar; String mCurFilter; LoginScreenFragment loginFragment; /** Called when the activity is first created. */ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.home); appContext = getApplicationContext(); actionbar = getSupportActionBar(); actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); ActionBar.Tab HomeTab = actionbar.newTab().setText("Home"); ActionBar.Tab CartTab = actionbar.newTab().setText("Cart"); ActionBar.Tab myTab = actionbar.newTab().setText("MyFragment"); ActionBar.Tab moreTab = actionbar.newTab().setText("More..."); HomeFragment homeFragment = new HomeFragment(); CartFragment cartFragment = new CartFragment(); MyFragment myFragment = new MyFragment(); MoreFragment moreFragment = new MoreFragment(); loginFragment = new LoginScreenFragment(); HomeTab.setTabListener(new MyTabsListener(homeFragment)); CartTab.setTabListener(new MyTabsListener(cartFragment)); myTab.setTabListener(new MyTabsListener(myFragment)); moreTab.setTabListener(new MyTabsListener(moreFragment)); actionbar.addTab(HomeTab); actionbar.addTab(CartTab); actionbar.addTab(myTab); actionbar.addTab(moreTab); ft = getSupportFragmentManager().beginTransaction(); ft.add(R.id.fragment_container, homeFragment); ft.show(homeFragment); ft.add(R.id.fragment_container, cartFragment); ft.hide(cartFragment); ft.add(R.id.fragment_container, myFragment); ft.hide(myFragment); ft.add(R.id.fragment_container, moreFragment); ft.hide(moreFragment); ft.add(R.id.fragment_container, loginFragment); ft.hide(loginFragment); ft.commit(); } @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putInt("tab", getSupportActionBar() .getSelectedNavigationIndex()); System.out.println("onSaveInstanceState"); } @Override public boolean onCreateOptionsMenu(final Menu menu) { MenuItem item = menu.add("Search"); item.setIcon(android.R.drawable.ic_menu_search); item.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS); View searchView = SearchViewCompat.newSearchView(this); if (searchView != null) { SearchViewCompat.setOnQueryTextListener(searchView, new OnQueryTextListenerCompat() { @Override public boolean onQueryTextChange(String newText) { mCurFilter = !TextUtils.isEmpty(newText) ? newText : null; return true; } }); item.setActionView(searchView); } MenuItem loginItem = menu.add("Login"); loginItem.setTitle("Login"); loginItem.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS); loginItem.setOnMenuItemClickListener(new OnMenuItemClickListener(){ @Override public boolean onMenuItemClick(MenuItem item) { //I wanted to show "loginFragment" when the Login button is clicked.But unfortunately its not showing up.Also the application is not giving any errors or crashing ft.show(loginFragment); return false; } }); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { int itemId = item.getItemId(); if (itemId == R.id.menuitem_home) { Toast.makeText(appContext, "Home", Toast.LENGTH_SHORT).show(); return true; } else if (itemId == R.id.menuitem_shop) { Toast.makeText(appContext, "Shop", Toast.LENGTH_SHORT).show(); return true; } else if (itemId == R.id.menuitem_cart) { Toast.makeText(appContext, "Cart", Toast.LENGTH_SHORT).show(); return true; } else if (itemId == R.id.menuitem_my) { Toast.makeText(appContext, "My", Toast.LENGTH_SHORT).show(); return true; } else if (itemId == R.id.menuitem_more) { Toast.makeText(appContext, "More...", Toast.LENGTH_SHORT).show(); return true; } return false; } static class MyTabsListener implements ActionBar.TabListener { public SherlockFragment fragment; public MyTabsListener(SherlockFragment fragment) { this.fragment = fragment; } @Override public void onTabReselected(Tab tab, FragmentTransaction ft) { System.out.println("TabReselected " + tab.getPosition()); } @Override public void onTabSelected(Tab tab, FragmentTransaction ft) { System.out.println("TabSelected " + tab.getPosition()); ft.show(this.fragment); } @Override public void onTabUnselected(Tab tab, FragmentTransaction ft) { System.out.println("TabUnselected " + tab.getPosition()); ft.hide(this.fragment); } } } </code></pre>
