I have my navigation drawer activity as my MainActivity class and I already have Homepage.class activity previously made. Since Navigation Drawer uses Fragments, I am unable to call Homepage class through Drawer. Plz help me.
Here is my code for the Drawer-
public class MainActivity extends Activity {

// nav drawer title
private CharSequence mDrawerTitle;
// used to store app title

// nav drawer icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

XML for the drawer:
<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:layout_height="match_parent" >
<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<!-- Listview to display slider menu -->
<ListView
android:id="#+id/list_slidermenu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#color/list_background"
android:choiceMode="singleChoice"
android:divider="#color/list_divider"
android:dividerHeight="1dp"
android:listSelector="#drawable/list_selector" />
</android.support.v4.widget.DrawerLayout>
And Finally XML for the activity which I want to be called -
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="#null" />
</LinearLayout>
The API for starting an Activity does not change when using a navigation drawer. You still only need to call startActivity() to launch a different Activity.
In this case, your code will look something like this:
private void displayView(int position) {
// update the main content by replacing fragments
Fragment fragment = null;
switch (position) {
case 0: // Or whatever nav item position should start the Activity
startActivity(new Intent(this, HomePage.class));
return;
// The rest of your cases
}
Note that when after calling startActivity() for the homepage item, we return instead of break so that your displayView() doesn't try to replace the displayed Fragment.

I've googled this for quite a while and nothing seems to match my issue. When my app starts the hamburger is fixed (no animation) until I do an orientation change, then it animates in both layouts. I'm using the ActionBarDrawerToggle from the v4 support pack (deprecated, I know). Here's the (fairly standard) code:

// nav icons from resources

Can anyone see where I've gone wrong and how to get the hamburger to animate all the time? Thanks!
I'm new to android. My requirement is: I am having a home activity with a drawer layout (Navigation Drawer). I also have fragments with ViewPager.
My issues is, when I select other fragments, the slider works, but when I select the fragment with ViewPager(Fragment2 here in the code) the slider stops working.

I was trying to implement Dynamically updating a list in a ListFragment.
But, when i change my fragment(i.e. from fragment 1 to fragment 2 and back to fragment 1) the list contents are lost.
Below is my ListFragment.
public class FragmentOne extends ListFragment {
String[] order = new String[] {};
public FragmentOne(){}
/** Items entered by the user is stored in this ArrayList variable */
ArrayList<String> list = new ArrayList<String>();
/** Declaring an ArrayAdapter to set items to ListView */
ArrayAdapter<String> adapter;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

Thanks in advance
When you go back from Fragment2 to Fragment1, you're creating a new instance of Fragment1. So of course your ListView will be empty (until the user adds items via the button you're supplying).
Maybe you need to modify displayView(int position) so it doesn't create an instance everytime, by null-checking and global vars maybe?
as #lenix mentioned when you come back to fragment1 the displayView does create a new fragment because you say that to the FragmentManager I've created new one and replace it..
In this case you should check isFragment added already? no then add otherwise hide and show fragment..
FragmentTransaction transaction = fragmentManager.beginTransaction();
if(fragment1.isAdded){
transaction.show(fragment1)
}else{
transaction.add(fragment1)
}
dont forget to commit when you done.. and its just way to see you how you can do.. this snippet doesnt work..
Each time you load your fragment, your ArrayList will start off empty. You could save the current list items to shared preferences and have the list fetched each time the fragment is loaded, or implement a set/get callback in your activity.
The error The method getSupportFragmentManager() is undefined for the type Context occur when i used getSupportFragmentManager() inside my oncreateview.
Different context type reference was used to overcome this error but none of these works:
e.g. globalContext = container.getContext(); globalContext = getActivity().getApplicationContext();
getSupportFragmentManager() can be set only in FragmentActivity. My question is if there is a way to reference getSupportFragmentManager().
My fragment.
public class HomeFragment extends Fragment implements
ActionBar.TabListener {
public HomeFragment(){}
Context globalContext;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_home, container, false);
globalContext = this.getActivity();
actionBar = getActivity().getActionBar();
android.support.v4.app.FragmentManager fm = globalContext.getSupportFragmentManager(); // getting error The method getSupportFragmentManager() is undefined for the type Context }}
mAdapter = new TabsPagerAdapter(fm);
}
}
}
the tabhostlistner adapter.
import android.support.v4.app.FragmentManager;
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fragmentManager) {
super(fragmentManager);
}}

1) Create the member variable:
private FragmentActivity context;
2) Override the onAttach method of your fragment:
#Override
public void onAttach(Activity activity) {
context = (FragmentActivity) activity;
super.onAttach(activity);
}
3) Get the support FragmentManager like this:
FragmentManager fm = context.getSupportFragmentManager();
In Kotlin
bottomSheetDialogFragment.show((context as FragmentActivity).supportFragmentManager,
bottomSheetDialogFragment.tag)
I am 100% sure that you are not importing the right package for the support Fragment class
make sure that your Fragment import in your HomeFragment look like this:
import android.support.v4.app.Fragment;
you can access Fragment manager in your getView method like below
((Activity)context).getFragmentManager().beginTransaction().replace(R.id.content_frame, fragment).commit();
where context is an activity ref passed in adapter class
like
public ActorAdapter(Context context, int resource, ArrayList<Actors> objects)
{
super(context, resource, objects);
this.context = context;
}
so fragment manager can be accessed for ex. FragmentManager fm = ((Activity)context).getFragmentManager();
Im new to the ActionBarCompat library.I want to develop an app which contains multiple fragments. Here is what i want to do
1.How to open a fragment when user select that from Navigation Drawer.
2.How to set a startup fragment which displays startup layout (example- In Google plus app,first its displays news feeds.when we select profile item from the side menu,then its hide the side menu/Navigation drawer and displays the profile layout)
Currently i have side menu and one fragment.
Here is the tutorial that i used to follow- wptrafficanalyzer
If you are going to use a slide out menu I recommend you use this slidemenu library I use it in my applications and it allows you to place whatever you want in the slide out menu, the menu is just a frame layout and you can put whatever you want in it (Listview, GridView, or even just a picture)
I am assuming by side menu you meant Navigation Drawer. You can find an answer in the below link.
Navigation Drawer with backword compatibility android
Do read
http://developer.android.com/design/patterns/navigation-drawer.html
Fragment is hosted by a Activity. So you need a container in the activity layout.
<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:layout_height="match_parent">
<FrameLayout // container to which you add or replace fragments
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<ListView
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"/>
</android.support.v4.widget.DrawerLayout>
Initially you don't click any item. So initially add fragment1 to the container.
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment1= new Fragment1();
fragTran.add(R.id.content_frame, fragment1);
fragTran.commit();
On click of listitem based on the position
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment3= new Fragment3();
fragTran.replace(R.id.content_frame, fragment3);
fragTran.commit();
