android - FragmentActivity and Navigation Drawer

Problem : When I click an item on the drawer it doesn't show the FragmentActivity that is supposed to be shown. App is ok it doesn't have errors when I compile it and It doesn't crash when I click an item in the drawer
MainActivty
private void displayView(int position) {
// update the main content by replacing fragments
FragmentActivity fragment = null;
switch (position) {
case 0:
fragment = new HomeFragment();
break;
case 1:
fragment = new LocateFragment();
break;
case 2:
fragment = new SecureFragment();
break;
case 3:
fragment = new NotificationFragment();
break;
default:
break;
}
if (fragment != null) {
LayoutInflater inflater = getLayoutInflater();
LinearLayout container = (LinearLayout)findViewById(R.id.frame_container);
inflater.inflate(R.layout.activity_main,container);
//FragmentManager fragmentManager = getFragmentManager();
//fragmentManager.beginTransaction()
//.replace(R.id.frame_container, fragment).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
setTitle(navMenuTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else {

Log.e("MainActivity", "Error in creating fragment");
}

if (fragment != null) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.add(R.id.frame_container,fragment);
transaction.commit();
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
setTitle(navMenuTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
I guess you are after something like this. You will with this put the fragment in the container view. Hope it helps

Load content of Navigation drawer item and ViewPagerStrip item on same container - Android

I am developing an application, It has an Activity(MainActivity.java) ,I integrated Navigation Drawer over it ,when I click navigation drawer item then the content of navigation drawer item loads on the <framelayout /> ,after that I integrated tabs at bottom on the same page (MainActivity.java) using ViewPagerStrip ,Now Problem is that :
When I click on Navigation drawer item and tabs item the content of Navigation Drawer item and ViewPagerStrip item is not being loaded on the same container ,How can I load content of both (tabs item and drawer item ) on the same container (Framelayout or ViewPager) .
I have following code in MainActivity.java
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Set activity_main.xml
setContentView(R.layout.activity_main);
//Create tabs at bottom using ViewPagerStrip
mCustomPagerAdapter = new CustomPagerAdapter(getSupportFragmentManager(), this);
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mCustomPagerAdapter);
//Create NavigationDrawer .
---------------------------------------
---------------------------------------
---------------------------------------
}
//Click on Drawer menus
private class SlideMenuClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// display view for selected nav drawer item
displayDrawerItem(position);
}
}
private void displayDrawerItem(int position) {
// update the main content by replacing fragments
Fragment fragment = null;
switch (position) {
case 0:
fragment = new HomeFragment();
break;
case 1:
fragment = new FindPeopleFragment();
break;
//Other fragments goes here .
default:
break;
}
if (fragment != null) {
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
setTitle(navMenuTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else {
// error in creating fragment
Log.e("MainActivity", "Error in creating fragment");
}
}
}
I have following code in my activity_main.xml
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"

android:dividerHeight="1dp"
android:listSelector="#drawable/list_selector"
android:background="#color/list_background"/>
</android.support.v4.widget.DrawerLayout>
My own efforts
I tried to solve this problem with different-2 approaches
1 . I put <ViewPager > inside <framelayout > and tried to load click events of navigation item and tabs item on the ViewPager .
2 . I removed <framelayout > and tried to load click events of navigation and tabs items both on the ViewPager .
3 . I follow many Stackoverflow links ,tutorials regarding ViewPagerStrip and DrawerLayout , tried to search how to load click events of drawer item and tabs item on the same container .
Edit
public class CustomPagerAdapter extends FragmentPagerAdapter {
Context mContext;
private String[] tabs = {"Trails", "Breweries", "Near By", "Events"};
public CustomPagerAdapter(FragmentManager fragmentManager, Context context) {
super(fragmentManager);
mContext = context;
}
#Override
public android.support.v4.app.Fragment getItem(int position) {
// Create fragment object
android.support.v4.app.Fragment fragment = new DemoFragment();
// Attach some data to the fragment
// that we'll use to populate our fragment layouts
Bundle args = new Bundle();
args.putString("page_name", tabs[position]);
// Set the arguments on the fragment
// that will be fetched in the
// DemoFragment#onCreateView
fragment.setArguments(args);
return fragment;
}
#Override
public int getCount() {
return tabs.length;
}
#Override
public CharSequence getPageTitle(int position) {
return tabs[position];
}}
public class DemoFragment extends android.support.v4.app.Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// Inflate the layout resource that'll be returned
View rootView = inflater.inflate(R.layout.fragment_tab, container, false);
// Get the arguments that was supplied when
// the fragment was instantiated in the
// CustomPagerAdapter
Bundle args = getArguments();
((TextView) rootView.findViewById(R.id.textView)).setText(args.getString("page_name"));
return rootView;
}}

See xml layout below:

android:choiceMode="singleChoice"
android:divider="#color/list_divider"
android:dividerHeight="1dp"
android:listSelector="#drawable/list_selector" />
</android.support.v4.widget.DrawerLayout>
Here when you click to tab set the frame_container visibility gone and when you click on navigation drawer item make the frame_container visibility visible.
Hope this will help.

Replacing fragments in one activity

I am able to add a fragment to my fragmentlayout, but when I'm trying to replace the fragment with a new one the screen is blank. I can add a new fragment but then it's not scrollable. I'm also not able not remove a fragment.
Does someone know what I'm doing wrong? I red a lot about it and I feel like I have tried everything..
The framelayout is defined static:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minWidth="25px"
android:minHeight="25px">
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>'
And this is the method for switching fragments:
void TabOnTabSelected (object sender, ActionBar.TabEventArgs tabEventArgs)
{
ActionBar.Tab tab = (ActionBar.Tab)sender;
var fragmentTransaction = FragmentManager.BeginTransaction ();
switch (tab.Text) {
case "vandaag":
if (currentFragment != null) {
fragmentTransaction.Remove (FragmentManager.FindFragmentByTag ("gister"));
}
if (fragmentToday == null) {
fragmentToday = WZWVDataOverview.NewInstance (DateTime.Now.AddDays (0).ToString ("d-M-yyyy"));
}
fragmentTransaction.Add (Resource.Id.fragment_container, fragmentToday, "vandaag");
currentFragment = fragmentToday;
break;
case "gister":
if (currentFragment != null) {
fragmentTransaction.Remove (currentFragment);
}
if (fragmentYesterday == null) {
fragmentYesterday = WZWVDataOverview.NewInstance (DateTime.Now.AddDays (-1).ToString ("d-M-yyyy"));
}
currentFragment = fragmentYesterday;
fragmentTransaction.Add (Resource.Id.fragment_container, currentFragment, "gister");
break;
case "morgen":
if (currentFragment != null) {
fragmentTransaction.Remove (currentFragment);
}
if (fragmentTomorrow == null) {
fragmentTomorrow = WZWVDataOverview.NewInstance (DateTime.Now.AddDays (+1).ToString ("d-M-yyyy"));
}
fragmentTransaction.Add (Resource.Id.fragment_container, fragmentTomorrow);
currentFragment = fragmentTomorrow;
break;
}
fragmentTransaction.Commit ();
}
XML of the framelayout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minWidth="25px"
android:minHeight="25px">
<ListView
android:minWidth="25px"
android:minHeight="25px"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/list" />
</LinearLayout>
Huge thanks in advance!

You can try using the .replace method. If you do not wish to be able to move back to the previous fragment than you can remove addToBackStack().
This may need to be altered slightly to fit your application.
FragmentManager fragmentManager = getFragmentManager();
Fragment mFragment = new DetailFragment();
mFragment.setArguments(bundle);
fragmentManager.beginTransaction().replace(R.id.fragment_container, mFragment).addToBackStack("DETAILFRAGMENT").commit();
POSSIBLE SECOND SOLUTION:
Check to see how your Fragment layout XML is. Possibly try using a FrameLayout as the parent.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.modup.fragment.DetailFragment">
<!-- TODO: Update blank fragment layout -->
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
</LinearLayout>
</FrameLayout>

I have open fragments from navigation view as items are selected from it.(I have use DataBinding Concept)

}
//items are selected from navigationView
public void selectItem(MenuItem menuItem) throws IllegalAccessException, InstantiationException {
switch (menuItem.getItemId()) {
case R.id.Home:

}
private ActionBarDrawerToggle setupToogle() {
return new ActionBarDrawerToggle(this, mainBinding.drawerLayout, mainBinding.toolbar, R.string.open, R.string.close);
}
menu/listnavigation.xml is attached to navigation view I contains items of navigation view.
In my code as items are selected from navigation view accordingly fragment is replaced. Here Home, Product, Media are my fragment, you can create any fragment.

Try using fragmentTransaction.replace() instead of fragmentTransaction.add() and comment out code for removing fragments. When you replace the fragment - it gets removed. Also - remember to call: fragmentTransaction.commit() when you are done with replacing fragments.

Cardslib Fragment not responding when interacted in Navigation Drawer

The fragment I'm having problems with is using a CardListView from the Cardslib library. I added the fragment dynamically to the container and everything is working as expected, except it isn't responding when it is interacted with. This means it doesn't scroll, I can't press on any of the cards, and anything else related to the problem.
Adding fragment to container in MainActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
// Code here...
NoteFragment nf = new NoteFragment();
// nf.setArguments(getIntent().getExtras());
FragmentTransaction tx = getFragmentManager().beginTransaction();
tx.add(R.id.container, nf);
tx.commit();
}
Replaces container fragment when Navigation Drawer is used in MainActivity. Default case selected is NoteFragment.
#Override
public void onNavigationDrawerItemSelected(int position) {
// update the main content by replacing fragments
Fragment fragment = null;
switch(position) {
case 0:
onSectionAttached(0);
fragment = new NoteFragment();
break;
case 1:
onSectionAttached(1);
fragment = new ArchiveFragment();
break;
case 2:
onSectionAttached(2);
fragment = new TrashFragment();
break;
}
FragmentTransaction tx = getFragmentManager().beginTransaction();
tx.replace(R.id.container, fragment);
tx.commit();
}
NoteFragment returning inflated layout:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// CardListView Code Here...
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_note, container, false);
}
Container XML (activity_main.xml):
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout

<!-- The drawer is given a fixed width in dp and extends the full height of
the container. -->
<fragment android:id="#+id/navigation_drawer"
android:layout_width="#dimen/navigation_drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"
android:name="com.example.NavigationDrawerFragment"
tools:layout="#layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>
Fragment XML (fragment_note.xml):
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".fragments.NoteFragment">

android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="5dp"
android:id="#+id/CardList"/>
</FrameLayout>
Any help is appreciated.

I fixed it! The Cardslib piece of code in onCreateView() was moved to onStart(), and it fixed the unresponsiveness.

Change between fragment navigation drawer viewpagerindicator

I have a Navigation Drawer and a ViewPagerIndicator inside the content_frame. I want to change between fragment`s from the navigation drawer but the problem is that switch between tabs ViewPager works but when I switch to another option that you have to remove the ViewPager and put a new fragment puts this fragment under the ViewPager.
Attached photo so you can see.
1) Here you can already see the new fragment below ViewPager.It can be distinguished by the text shown is Prueba

I do not know if I have to destroy the viewpager to show the new fragment or a problem of hierarchy in the xml.

Your ViewPager must be Fragment, and it should be placed to layout.content_frame, so when you calling ft.replace(R.id.content_frame, fragment); your ViewPager fragment will be replaced.

You should not use ViewPager and NavigationDrawer at the same time. You can see Roman Nurik's answer in this G+ post:
https://plus.google.com/u/1/+DavidTaSmoochibi/posts/8dWEkFcbTFX
"You shouldn't use navigation drawers with action bar tabs. If you're aiming for a UI similar to that of Google Play Music, you should implement tabs manually (and beware of how this looks on tablet—you don't want full-width tab bars on tablets). Also make sure to check out the Structure in Android App Design session from this year's Google I/O for a detailed run-through of the various interface patterns available for exposing app hierarchy."
