I have a MainActivity that contains a NavigationView for the drawer menu. The NavigationView's header contains a TextView that I want to populate with some user information.
The problem is, that sometimes the app crashes in the onChanged method with a NullPointerException because textUsername is null. My guess is that's because the layout has not been fully inflated yet. I have implemented the null check (as seen in the code below), which obviously just results in the textUsername being blank in most cases.
My onCreate method looks like this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mainViewModel = ViewModelProviders.of(this).get(MainViewModel.class);
mainDrawerLayout = (DrawerLayout) findViewById(R.id.main_drawer_layout);
mainNavigationView = (NavigationView) findViewById(R.id.main_navigation_view);
mainContentLayout = (CoordinatorLayout) findViewById(R.id.main_content_layout);
// get user information
NetworkController.getInstance().getCurrentUser(Utils.getAuthenticationToken(), new NetworkController.GetUserResponseCallback() {
#Override
public void onGetUser(Response<UserResponse> response) {
if(response.isSuccessful() && response.body() != null && response.body().isSuccess()) {
mainViewModel.setCurrentUser(response.body().getUser());
}
}
#Override
public void onRequestFailed(Throwable throwable) {
}
});
mainViewModel.getCurrentUser().observe(this, new Observer<User>() {
#Override
public void onChanged(#Nullable User user) {
TextView textUsername = (TextView) mainNavigationView.findViewById(R.id.drawer_header_username);
if(textUsername != null) {
textUsername.setText(user.getProfile().getUsername());
}
}
});
}
How can I make sure that that layout is inflated before I access it from the callback? Thanks.

I wonder why such a strange behavior in the app attribute: elevation = "0dp" and how to solve the problem. I use the androidx library. The toolbar is transparent. Shadow remains. When I write an app: elevation = "0dp", the shadow disappears, but the toolbar buttons, including the "back" buttons, stop responding.
I tried to solve it in other ways: android: elevation = "0dp"
programmatically set getSupportActionBar (). setElevation (0); Does not help.

Try the below code snippet instead of toolbar.setNavigationOnClickListener
#Override public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId() == android.R.id.home){
getActivity().onBackPressed();

return super.onOptionsItemSelected(item);
}
hope this will solve your problem.
thanks
This is just because you have used FrameLayout as a parent - and also removed elevation from AppBarLayout, and due to this, Your ScrollView is overlapping your AppBarLayout as it is written below AppBarLayout. change your root to something else, for eg.

You should use below property so your viewPager below your upper tab. I think your viewPager have height and width both are match parent.
Since you are using RelativeLayout as root component you have to give margin top to RecyclerView:
android:layout_marginTop="104dp"
EDIT:
if you were using coordinatorLayout as Root layout, the story would be different.
EDIT
Following issues are obvious in your codes:
1- AppBarLayout in Fragment home is extra since you have already an Appbar in activitie's home layout.
2- According to android official document use CoordinatorLayout instead of RelativeLayout. By using RelativeLayout you will loose some functionality and layout management of AppBarLayout
3- Since you have just included content_main inside app_bar_main, no needs to use tools:context=".MainActivity" and tools:showIn="#layout/app_bar_main"
4- Replace RelativeLayout inside content_main by merge tag
After above changes you have just removed extra layouts which may have side effects on margins and padings, then apply attribute below to your view pager. I hope these changes will be effective and no other hidden items are alive in your code:
android:layout_marginTop="104dp"
change you Relativelayout to android.support.design.widget.CoordinatorLayout and add app:layout_behavior="#string/appbar_scrolling_view_behavior" to android.support.v7.widget.RecyclerView
Use this for app_mar_main:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbarlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:popupTheme="#style/AppTheme.PopupOverlay" />
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorPrimaryDark"
app:tabTextColor="#color/colorAccent"
app:tabSelectedTextColor="#color/colorAccent"
android:id="#+id/tabs">
<android.support.design.widget.TabItem
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/tab_np"
android:text="#string/now_playing"
android:textColor="#color/colorAccent"/>
<android.support.design.widget.TabItem
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/up_coming"
android:id="#+id/tab_up"/>
</android.support.design.widget.TabLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_below="#+id/appbarlayout"
android:layout_marginTop="1dp"/>
</RelativeLayout>
Try this way..
make viewpager xml code..
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/tab_bg_color"
android:orientation="vertical">
<android.support.design.widget.TabLayout
android:id="#+id/tlConversation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
app:tabIndicatorColor="#color/tab_color"
app:tabMinWidth="0dp"
app:tabMode="fixed"
app:tabTextAppearance="#style/Tab_Style"
app:tabSelectedTextColor="#color/tab_color"
app:tabTextColor="#color/tab_text_color">
</android.support.design.widget.TabLayout>
<android.support.v4.view.ViewPager
android:id="#+id/vpPager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white">
</android.support.v4.view.ViewPager>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
after that fragement xml code for recyclerview ..
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tool="http://schemas.android.com/tools">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/rvData"
tool:listitem="#layout/item_row_layout"
></android.support.v7.widget.RecyclerView>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/tvEmpty"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
tool:text="No data found"
android:text="#string/no_found"
android:visibility="gone"
/>
</android.support.constraint.ConstraintLayout>
after that setup view pager like this way make viewpager adapter..
private void setupViewPager(ViewPager viewPager) {
viewPagerAdapter = new ViewPagerAdapter(getActivity().getSupportFragmentManager(),conversationId);
viewPager.setAdapter(viewPagerAdapter);
viewPager.setOffscreenPageLimit(1);
viewPager.setCurrentItem(currentItem);
}
And
public class ViewPagerAdapter extends FragmentPagerAdapter {
private final Context context;
public ViewPagerAdapter(FragmentManager fragmentManager, Context context) {
super(fragmentManager);
this.context = context;
}
#Override
public Fragment getItem(int position) {
if(position == 0) return new ActiveConversationFragment();
if(position == 1) return new InvitedConversationFragment();
if(position == 2) return new RecentConversationFragment();
throw new IllegalStateException("Unexpected position " + position);
}
#Override
public int getCount() {
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
if(position == 0) return context.getString(R.string.tab_active_conversation_title);
if(position == 1) return getString(R.string.tab_invited_conversation_title);
if(position == 2) return getString(R.string.tab_recent_conversation_title);
throw new IllegalStateException("Unexpected position " + position);
}
}
after that call above method like this way set into tablayout..
setupViewPager(viewPager);
tabLayout.setupWithViewPager(viewPager);
I want to move the whole layout down when SwipeRefreshLayout Listener is called? Is this thing possile in android .?
This is my whole xml layout.SwipeRefreshLayout contains a progressbar and FrameLayout and that is included in a RelativeLayout.So I want the FrameLyout should pull down when I call for refresh.

try this. you have to set your SwipeRefreshLayout above. Hope it helps you. If this doesn't helps you ask me what is the problem i will help you
And My class code is below
mSwipeRefreshLayout1 = (SwipeRefreshLayout) findViewById(R.id.swp1);
//set colors if you need
mSwipeRefreshLayout1.setColorSchemeResources(R.color.colorPrimary, R.color.colorPrimaryDark, R.color.colorPrimaryLight);
mSwipeRefreshLayout1.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
mSwipeRefreshLayout1.setRefreshing(true);
try {
//Refresh data
} catch (Exception e) {
//Toast.makeText(getActivity(), String.valueOf(e.getMessage()), Toast.LENGTH_SHORT).show();
//customtoast.ShowToast(getActivity(), String.valueOf(e.getMessage()), R.layout.red_toast);
}
}
});
you can code like this
swipe.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
new class(getActivity(), listView, progressBar, mApp.getPreference().getString(Common.u_id, ""), "all", swipe).execute();
}
});
return view;
}
Include code below in your xml file
<RelativeLayout 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">

On my phone and that of a friend, the FAB in the default Android Studio Activity does not move down after the Snackbar dismisses.
On the emulator and a few other friends' phones, it does animate down.
The first friend and I have changed animation scale to 0.5, but setting it to 1.0 and rebooting hasn't fixed the issue.
This should have been fixed in Design Support Library 23.2.0, and I am using 23.3.0, as the example comes with that set.

As suggested by #ianhanniballake, this was fixed in Design Support Library 23.4.0.
I have an android app with preference
As you can see the preferences overlaps the toolbar.
This is my main fragment xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<FrameLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
which include a new xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include
layout="#layout/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/toolbar" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_partial_secure" />
</android.support.design.widget.CoordinatorLayout>
and finally the content_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.example.gilca.ebspma.MainActivity">
<TextView
android:id="#+id/location"
android:paddingTop="30dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
My xml preferences are this one
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<PreferenceCategory
android:summary="Username and password information"
android:title="Informações de Login">
<EditTextPreference
android:key="username"
android:summary="Introduzir username"
android:title="Username" />
<EditTextPreference
android:key="password"
android:summary="Introduzir password"
android:title="Password" />
</PreferenceCategory>
<PreferenceCategory
android:summary="sessao"
android:title="Definições">
<Preference
android:key="#string/myCoolButton"
android:summary="Mude aqui"
android:title="Mudar a password na BD" />
<CheckBoxPreference
android:key="checkBox"
android:summary="On/Off"
android:title="Manter Sessão" />
</PreferenceCategory>
</PreferenceScreen>
And this xml is called from SettingsFragment.java
public class SettingsFragment extends PreferenceFragmentCompat {
SharedPreferences sharedPreferences;
#Override
public void onCreatePreferences(Bundle bundle, String s) {
addPreferencesFromResource(R.xml.prefs);
sharedPreferences = PreferenceManager.getDefaultSharedPreferences(getActivity());
}
}
So...why do i have this problem and how can i fix that?
UPDATE
The code asked
public boolean onNavigationItemSelected(MenuItem item) {
Fragment fragment = null;
Class fragmentClass = null;
int id = item.getItemId();
if (id == R.id.nav_home) {
fragmentClass = HomeFragment.class;
} else if (id == R.id.nav_req) {
} else if (id == R.id.nav_ver) {
} else if (id == R.id.nav_atividades) {
fragmentClass = AtividadesFragment.class;
} else if (id == R.id.nav_training) {
fragmentClass = TrainingFragment.class;
} else if (id == R.id.nav_settings) {
fragmentClass = SettingsFragment.class;
}
else if (id == R.id.nav_about) {
}
else if (id == R.id.nav_sair) {
session.logOut();
System.exit(0);
}
try{
assert fragmentClass != null;
fragment = (Fragment) fragmentClass.newInstance();
}catch (Exception e) {
e.printStackTrace();
}
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content, fragment).commit();
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
Try to align your "content" frame layout in the main.xml to be below the "app_bar".
<include
android:id="#+id/app_bar"
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<FrameLayout
android:id="#+id/content"
android:layout_below="#id/app_bar"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
I'm a little confused about your layout hierarchy, particularly about
<FrameLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
and
<include
layout="#layout/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/toolbar" />
which could ultimately be used for the same function, which is be the main fragment container.
However, I know this issue could be a real pain in the ass and I have recently struggled with this (quite a lot actually) and finally found the answer. At least in my case, it was solved by just adding a LinearLayout as a parent of both AppBarLayout and your fragment container (in this case I don't know exactly which would be, the FrameLayout or your content_main layout).
If my explanation isn't clear enough please refer to Fragment overlaps my AppCompat toolbar.
Instead of doing something so complex, to just house an AppBar and FloatingActionButton, you can do the following:
In your layout file for the Settings Activity (say, activity_settings.xml)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".SettingsActivity"
android:orientation="vertical"
android:nestedScrollingEnabled="true"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:liftOnScroll="true">
<androidx.appcompat.widget.Toolbar
...
/>
</com.google.android.material.appbar.AppBarLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragment_container"/>
<FloatingActionButton
...
/>
</LinearLayout>
And any regular Preference Fragment will do.
