Toolbar overlaps the PreferenceFragment

Toolbar overlaps the PreferenceFragment - android

As you see in the title, The toolbar appears, but it overlaps my preferenceFragment content.
I fixed the issue on the Settings Screen by adding a padding to the listview.
But the problem persists in all the other preferenceFragments. Here is my code.

As you see in this photo, the "First Name" EditTextPreference is hidden by the toolbar:
I think, maybe it has something to do with the preference ressource files under xml/. so here a link to the files : https://github.com/waeljomni/apptest.git

The problem here is that you are inflating the activity_main.xml layout in android.R.id.content and the preference fragments into com.android.internal.R.id.headers (if you see the implementation of PreferenceActivity).
The default XML layout of PreferenceActivity is preference_list_content.
You should define in your team your custom preference layout in which you reproduce your main Activity layout.
See headerLayout in R.attr.preferenceActivityStyle.

I suggest to use ConstraintLayout for performance reason and simplicity

TABS Are not displayed in Fragment

BEFORE YOU DO ANY OF THIS MAKE SURE YOU HAVE A BACKUP OF YOUR PROJECT AS I HAVE NOT TESTED THIS!!!
INSIDE COORDINATORLAYOUT
Before the fragment_container I want you to place a FrameLayout, make sure it's layout_height is wrap_content. I want you to make it's id equal to realtabcontent. I want you to add the attribute layout_weight to fragment_container and make it equal to 1.
I want you to delete fragment main layout, MAKE SURE YOU HAVE A BACKUP OF THIS PROJECT!!!
INSIDE MAINFRAGMENT
I want you to change onCreateView to:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mTabHost = new FragmentTabHost(getActivity());
mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("fragmentc").setIndicator("Fragment C"), MovieFragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("fragmentb").setIndicator("Fragment B"), GalleryFragment.class, null);
return inflater.inflate(R.id.fragment_container, null);

Main activity Layout overlays SettingsActivity

I am currently trying to develop an android application which should have Settings. How far I am informed I should use a SettingsActivity.
Mine looks currently like this:

private static Preference.OnPreferenceChangeListener sBindPreferenceSummaryToValueListener = new Preference.OnPreferenceChangeListener() {
#Override
public boolean onPreferenceChange(Preference preference, Object value) {
String stringValue = value.toString();
if (preference instanceof ListPreference) {
ListPreference listPreference = (ListPreference) preference;
int index = listPreference.findIndexOfValue(stringValue);
preference.setSummary(
index >= 0
? listPreference.getEntries()[index]
: null);
} else if (preference instanceof RingtonePreference) {
if (TextUtils.isEmpty(stringValue)) {
preference.setSummary(R.string.pref_ringtone_silent);
} else {
Ringtone ringtone = RingtoneManager.getRingtone(
preference.getContext(), Uri.parse(stringValue));
if (ringtone == null) {
preference.setSummary(null);
} else {
String name = ringtone.getTitle(preference.getContext());
preference.setSummary(name);
}
}
} else {

}
return true;

The problem with this code is, that my preferences are not practically usable, because my MainActivity layout is shown above the settings. I have searched a lot for this, but still I cannot find an answer which satisfies my needs. A lot of guys said that you could use wrap the SettingsActivity with Layouts and Stuff, but to my knowledge this is not Good Practice programming which I am trying to do. And I know this is pretty near at the Google example, but I am currently starting to develop the application so this will be replaced! Thx in advance!
EDIT: Replaced the code with the new issue.

Yeah this is an annoying one! I ran into the same issue - The pattern used on the Android Developer site is dated to the days of API 10. My example below demonstrates how to implement Preferences using a modern Activity/Fragment design pattern.

I found my failure! After reading apelosoczi's answer I found out that in my app bar, I had an include with my main layout. Now after I declared my own app_bar for this it works! But now I have to add padding over the subsettings :( which does not work currently]1

Changing navigation drawer items at runtime

The case is the following: I have two types of users, type1 and type2. Both have to login in order to go to the main activity which has a Navigation Drawer. The items in the navigation drawer depends on the type of the user. How can I change the items of the navigation drawer at runtime after I know the user type.

I found easier way to change navigation view ( work with both submenu and menu). You can re-inflate NavigationViewat runtime with 2 lines of code. In this example i re-inflate with new_navigation_drawer_items.xml when user successfully logged-in
navigationView.getMenu().clear(); //clear old inflated items.
navigationView.inflateMenu(R.menu.logged_in_navigation_drawer_items); //inflate new items.
When user log out just re-inflate again with logged_out_navigation_drawer_items.xml
navigationView.getMenu().clear(); //clear old inflated items.
navigationView.inflateMenu(R.menu.logged_out_navigation_drawer_items); //inflate new items.

Up caret shows navigation drawer

Nothing much more to say. I'm using a single activity and I go into a Fragment which calls setDisplayHomeAsUpEnabled(Boolean.TRUE) and setHasOptionsMenu(Boolean.TRUE). The menu has two items and the interactions with them are right. I have set breakpoints on all onOptionsItemSelected of the app (which includes the Activity, the Fragment, and the drawer toggle) but when I debug, the menu opens and no breakpoint is triggered.
The Activity and Fragment code in case they help:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/navigation_drawer"
android:layout_width="match_parent"

I have opted for making an activity only for that fragment which doesn't include the nav drawer. But obviously this doesn't answer the question, it just gets a relatively similar behavior.

How to dynamically add user input into a listView within a fragment?

Im trying to add text into a listview within a fragment but i keep getting an error: cannot find symbol method setListAdapter(ArrayAdapter).
I'm using this tutorial as reference but it only shows how to do it within a activity : http://wptrafficanalyzer.in/blog/dynamically-add-items-to-listview-in-android/
Im trying to move this over to a fragment. Can anyone help please i would highly appreciate it? heres my code :
