I'm trying to use an unique activity that contain navigation view and their option will open another fragment. Everything is ok, unless the MainFragment is being recreated when back from another fragment (that was opened from the navigation view). I'd like to know how to avoid this because it's loading the list again.

Fragment 2 has a hello world text view for test purpose.
When you put your MainFragment to BackStack (means that the view
of this fragment is not visible because Fragment2 take the
screen), all the views which belong to it will be destroyed.
Then when you back to MainFragment from another fragment, view of
MainFragment will be re-created. That mean onCreateView and onViewCreated will be
called again.
In your case, I suggest:
Move new ScheduleServiceTask().execute(); to onCreate or to
another method (example: requestGetData())
Init mAdapter and set adapter for mRecyclerView in onViewCreated()
On setData() method, all you need is re-set data for mAdapter and call notifyDatasetChanged() function.
#Douglas Fomaro, Better you can move your data(mList) outside fragment. Maintain DataManager Class that hold all your list data value.

setHasOptionsMenu(true);
include this in fragment so that onOptionItemSelected() can be called.
Finally solved.
Now, if you want to listen to clicks on any type of NavigationIcon in your custom toolbar (be it a Hamburger or up-caret or some fancy icon) then use setToolbarNavigationClickListener(). No need to use onOptionsItemSelected Method.
Thanks Protino for suggestion
// Add the backstack listener
getSupportFragmentManager().addOnBackStackChangedListener(this);
// Handle clicks on the up arrow since this isnt handled by the
toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FragmentManager fm = getSupportFragmentManager();
// Pop the backstack all the way back to the initial fragment. Customize if needed
//fm.popBackStack(fm.getBackStackEntryAt(0).getName(), FragmentManager.POP_BACK_STACK_INCLUSIVE);
if(fm.getBackStackEntryCount() > 0) {
fm.popBackStack();

Well to call the activity method, you should use something like this
((YourActivityName)getActivity()).onBackPressed();
and for the log to work you need to include the tag too.
Log.d(TAG, "Your message");
I have a fragment that is half image and then half text.
Trying to assign the ImageView and the TextView but it says:
Might give null
and when I run the app it does not run.
I included the Java and XML files for fragment and included the mainActivity java.
Fragment code:
import android.media.Image;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.support.v4.app.Fragment;

ImageView image;
TextView text;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if(getView().findViewById(R.id.imageView ) != null)
{
image = (ImageView)getView().findViewById(R.id.imageView);
}
return inflater.inflate(R.layout.frag, container, false);
}
public void run(){
text.setText("Test");
}
}
Layout XML:
<?xml version="1.0" encoding="utf-8"?>

For fragment you should inflate first your xml in the onCreateView method, you get your view and you can find your corresponding ImageView:
View myView = inflater.inflate(R.layout.frag, container, false);
ImageView myImage = (ImageView) myView.findViewById(R.layout.my_image);
return myView;
In the xml you should add an id to the iamgeView in order to get it:
<ImageView
android:id="#+id/my_image"
android:layout_width="match_parent"
android:layout_height="300dp" />
Trying to assign the ImageView and the textView but it says Might give
null error and when i run the app it does not run.
That's a lint warning informing you that findViewById could return null. If your xml contains the id you are looking for, you don't have anything to worry about.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if(getView().findViewById(R.id.imageView ) != null)
getView() returns the View the onCreateView returns, therefore you can't use getView() inside onCreateView. Override onViewCreate instead, and its parameter View to perform your findViewById calls
In the fragment you first need to infalte the view and then assing values to its content
Example:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.frag, container, false);
ImageView image = (ImageView) rootView.findViewById(R.id.imageView);
TextView tv = (TextView) rootView.findViewById(R.id.yourTextViewId);
tv.setText("Test");
// Here you will perform all the actions that you want to perform and then in the end return the view like below
return rootView;
}
I've a NavigationDrawer that shows fragments in MainActivity when a menu item is clicked.
One of these fragments is called MainFragment that uses TabHost to show tabs. The tabs are another two fragments (FragmentOne and FragmentTwo).
It's all working but I can't code the swipe functionality and effects like WhatsApp tabs. I've searched many examples/tutorials but all of them show how to do it with an activity and I'm not able to implement it with fragments. I hope you can help me. Thank you.
Only one of my fragments need tabs.
MainFragment:
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTabHost;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.podtest.R;
public class MainFragment extends Fragment {
private FragmentTabHost mTabHost;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mTabHost = new FragmentTabHost(getActivity());
mTabHost.setup(getActivity(), getChildFragmentManager(), R.layout.fragment_main);
Bundle arg1 = new Bundle();
arg1.putInt("Arg for Frag1", 1);
mTabHost.addTab(mTabHost.newTabSpec("Tab1").setIndicator("Frag Tab1"),
FragmentOne.class, arg1);
Bundle arg2 = new Bundle();
arg2.putInt("Arg for Frag2", 2);
mTabHost.addTab(mTabHost.newTabSpec("Tab2").setIndicator("Frag Tab2"),
FragmentTwo.class, arg2);
return mTabHost;
}

For the swipe functionality you would be best off using a ViewPager paired with a TabLayout. Both are provided in the design support library.
You can see a working example here:
http://blog.grafixartist.com/material-design-tabs-with-android-design-support-library/
The above example is within an Activity, but I have used a similar so
