I can't get the Toolbar to show up. I did everything.
I'm not new to Android development.
I've used setSupportActionBar().
I tried to debug and see if getSupportActionBar() is not null. And it's null.
I don't know why it's. I've been experiencing this since I've started using Android DataBinding.
This is all I did:
binding = DataBindingUtil.setContentView(this, R.layout.activity_create);
createBinding = DataBindingUtil.setContentView(this, R.layout.content_create);
setSupportActionBar(binding.createToolbar);
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
String action = getIntent().getStringExtra("action");
if (action != null) {
if (action.equals("create")) {
getSupportActionBar().setTitle(R.string.create);
} else {
getSupportActionBar().setTitle(R.string.update);
}
}
}
And my XML
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:bind="http://schemas.android.com/apk/res-auto">
<data>

<include layout="#layout/content_create"
android:id="#+id/contentCreateHolder"
bind:customer="#{customer}"/>
</android.support.design.widget.CoordinatorLayout>
</layout>
Are you sure you want your content view to just be this layout?
<include layout="#layout/content_create"
android:id="#+id/contentCreateHolder"
bind:customer="#{customer}"/>
If not, remove this line
createBinding = DataBindingUtil.setContentView(this, R.layout.content_create);

I am trying to add a toolbar to my PreferenceActivity.
I have looked around here and a number of places and nothing seems to work.
I am using headers for my top-level.
I tried to then use my own layout in onCreate including the required toolbar and making sure it has a view by the name of "#android:id/list".
<?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"
android:orientation="vertical">
<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:title="#string/app_name"
app:navigationIcon="#drawable/back"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<ListView android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
This worked okay for the top level but then the next level failed looking for a view name "android:id/prefs".
java.lang.IllegalArgumentException: No view found for id 0x102040a (android:id/prefs) for fragment PreferencesFragmentButtonInteraction{7a6584a #0 id=0x102040a}
The only code in the onCreate of the fragment is the AddPreferencesFromResource.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preferences_button_interaction);
}
I have tried to use a theme and set in in the manifest but to no avail.
You can use PreferenceFragmentCompat wrapped in a normal AppCompatActivity. Then you can easily attach an appbar to your activity using
setContentView(R.layout.activity_setting);
and preferences can be set to the fragment using
setPreferencesFromResource(R.xml.preferences_button_interaction, rootKey);
If you wish to add toolbar to your current activity, you can try this method
private void setupActionBar() {
ViewGroup rootView = (ViewGroup)findViewById(R.id.action_bar_root); //id from appcompat
if (rootView != null) {
View view = getLayoutInflater().inflate(R.layout.app_bar_layout, rootView, false);
rootView.addView(view, 0);
Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
// Show the Up button in the action bar.
actionBar.setDisplayHomeAsUpEnabled(true);
}
}

I tried to implement my toolbar with my activity but it's not inflating and keeps showing an error. My project does not use AppCompat but I'm not sure whether or not that is also the vause of the error.
Error inflating class android.widget.Toolbar
Java
public class MainActivity extends Activity {

setActionBar(customToolbar);
//add back arrow to toolbar
if (getActionBar() != null){
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setDisplayShowHomeEnabled(true);
}
TextView mTitle = this.findViewById(R.id.toolbar_title);
mTitle.setText(getString(R.string.select_a_destination_station));
mTitle.setTextColor(Color.WHITE);

Try this.
In the Toolbar_layout
One way
change
<android.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar_1line"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:minHeight="?android:attr/actionBarSize">
</android.widget.Toolbar>
to
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar_1line"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="?attr/colorPrimary"
android:minHeight="?android:attr/actionBarSize">
</android.support.v7.widget.Toolbar>
In the java code
change
Toolbar customToolbar = findViewById(R.id.toolbar_1line);
setActionBar(customToolbar);
//add back arrow to toolbar
if (getActionBar() != null){
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setDisplayShowHomeEnabled(true);
}
to
Toolbar customToolbar = (Toolbar) findViewById(R.id.toolbar_1line);
setSupportActionBar(customToolbar);
//add back arrow to toolbar
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
Another way
change
<android.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar_1line"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:minHeight="?android:attr/actionBarSize">
</android.widget.Toolbar>
to
<Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar_1line"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="?attr/colorPrimary"
android:minHeight="?android:attr/actionBarSize">
</Toolbar>
It's easy.
I am trying to migrate from MvxTabActivity to the new ViewPager. The problem is that when you do this, you no longer have a default ActionBar and have to define one in your layout. Here is my Layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
local:popupTheme="#style/ThemeOverlay.AppCompat.Light"
local:layout_scrollFlags="scroll|enterAlways" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="16dp"
local:tabGravity="center"
local:tabMode="scrollable" />
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="fill_parent"
local:layout_behavior="#string/appbar_scrolling_view_behavior" />
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
This is my Activity:
[Activity(Label = "PayItemView", Theme = "#style/MPSTheme")]
public class PayItemView : MvxFragmentActivity
{
PayItemViewModel vm;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
Android.Support.V7.Widget.Toolbar myToolbar = (Android.Support.V7.Widget.Toolbar)FindViewById(Resource.Id.toolbar);
myToolbar.Title = "Current Pay Summary - " + Common.Settings.DriverName;
}
protected override void OnViewModelSet()
{
base.OnViewModelSet();
SetContentView(Resource.Layout.PayItemView);
vm = (this.DataContext as PayItemViewModel) ?? null;
var viewPager = FindViewById<ViewPager>(Resource.Id.viewpager);
if (viewPager != null)
{
var fragments = new List<MvxCachingFragmentStatePagerAdapter.FragmentInfo>
{
new MvxCachingFragmentStatePagerAdapter.FragmentInfo("OTR", typeof (OTRTabView),
typeof (OTRTabViewModel)),
new MvxCachingFragmentStatePagerAdapter.FragmentInfo("LPP", typeof (LPPTabView),
typeof (LPPTabViewModel)),
new MvxCachingFragmentStatePagerAdapter.FragmentInfo("Hours", typeof (HourTabView),
typeof (HourTabViewModel)),
};
viewPager.Adapter = new MvxCachingFragmentStatePagerAdapter(this, SupportFragmentManager, fragments);
}
var tabLayout = FindViewById<TabLayout>(Resource.Id.tabs);
tabLayout.SetupWithViewPager(viewPager);
}
}
I created my style as follows:
<style name="MPSTheme" parent="Theme.AppCompat">
<item name="colorPrimary">#3f51b5</item>
</style>
I added a random color to the colorPrimary attribute of the Style and it works. The problem is that the rest of my App uses the device default color for the ActionBar. If you don't use a Theme based on Theme.AppCompat, it won't inflate your view. Is there a way to make my Theme be based on Theme.AppCompat and use the colorPrimary from the Device Default Theme?
Try wrapping it in an android.support.design.widget.AppBarLayout
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
local:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
local:tabIndicatorColor="#color/white"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
local:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.design.widget.CoordinatorLayout>
How can I set Elevation to 0 or disable it for a specific Fragment of my NavigationDrawer? Programmatically or with theme maybe ?
toolbar.setElevation(0) seems not working.
This ìn my onNavigationItemSelected doesn't work, elevation won't change :
if (item.getItemId() == R.id.drawer_menu_account) {
if (getSupportActionBar() != null) {
getSupportActionBar().setElevation(0);
}
} else {
if (getSupportActionBar() != null) {
getSupportActionBar().setElevation(8);
}
}
And there is my Coordinator layout with Toolbar
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

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>
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize" />
<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="#drawable/ic_add_24dp" />
</android.support.design.widget.CoordinatorLayout>
RESOLVED - Thanks to Amir ! Work with this in my onNavigationItemSelected
if (android.os.Build.VERSION.SDK_INT >= 21) {
if (item.getItemId() == R.id.drawer_menu_account) {
appBar.setElevation(0);
} else {
appBar.setElevation(8);
}
}
To remove shadow in Toolbar use
app:elevation="0" in AppBarLayout xml or
use mAppBarLayout.setTargetElevation(0) in java.
It worked for me.
I have an android app with preference
As you can see the preferences overlaps the toolbar.
This is my main fragment xml

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.
