I'm trying to replace an ActionBar with a toolbar, but the toolbar doesn't show up. I don't understand why my page is still blank without the toolbar, what am I missing?
My style:
<style name="MyThemeActionBar" parent="Theme.AppCompat.Light">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
My toolbar.axml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:layout_width="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/toolbartitile"
android:text="Kodej"/>
</android.support.v7.widget.Toolbar>
My activity:
[Activity(Label = "MainLoginActivity" , Theme = "#style/MyThemeActionBar")]
public class MainLoginActivity : AppCompatActivity
{
private ISharedPreferences sp;
private Android.Support.V7.Widget.Toolbar toolbar;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.MainLogin);
toolbar = FindViewById<Android.Support.V7.Widget.Toolbar>(Resource.Id.toolbar);
SetSupportActionBar(toolbar);
sp = GetSharedPreferences(null, FileCreationMode.Private);
TextView tv = FindViewById<TextView>(Resource.Id.emailMain);
tv.Text = sp.GetString("email", null);
tv.Click += (object sender, EventArgs e) =>
{
Android.Support.V7.App.AlertDialog.Builder ad = new Android.Support.V7.App.AlertDialog.Builder(this);
ad.SetTitle("Logout");
ad.SetMessage("Are you sure you want to logout");
ad.SetPositiveButton("Yes", (senderAlert, args) =>
{
ISharedPreferencesEditor editor = sp.Edit();
editor.Remove("email");
editor.Apply();
StartActivity(typeof(MainActivity));
Finish();
});
ad.SetNegativeButton("Cancel", (senderAlert, args) => {});
Dialog dialog = ad.Create();
dialog.Show();
};
}
}
I think the problem could be with the code:
toolbar = FindViewById<Android.Support.V7.Widget.Toolbar>(Resource.Id.toolbar);
Since you didn't post your code of your MainLogin layout, when you code this in your MainLoginActivity, the context is MainLoginActivity, and you should make sure there is a Android.Support.V7.Widget.Toolbar which ID is toolbar existing in the MainLogin layout, otherwise, this will return a null, and it won't throw an exception when you SetSupportActionBar(toolbar);.
To solve this issue, you can:
Move your layout for your Toolbar into MainLogin layout.
Or keep your Toolbar in your toolbar layout but use it in your MainLogin layout for example like this:
MainLogin layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include android:id="#+id/toolbar"
layout="#layout/mytoolbar" />
</LinearLayout>
Context
I have a base activity which contains a drawer navigation from the example in android studio. I made the statusbar transparent and I want the menu to slide under it allowing its color to overflow into the transparency like this:
(notice the blue on the right)
However on default it looks like this:
Question
The blue color is from the theme colorPrimaryDark, however I want to dynamically change this color, so I can't rely on the theme. Is there any way to dynamically/programmatically set the color?
Things I've tried
Adjusting the color of the decor view; getWindow().getDecorView().setBackgroundColor(Color.White)
Setting color of the statusbar and use the flag
DRAWS_SYSTEM_BAR_BACKGROUNDS:
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(Color.BLUE);
}
(Sorry for the poor coding block, it doesn't want to listen)
This will not make it transparent as the first image, but simply a solid color.
Changing the color of the rootView anyView.getRootView().setBackgroundColor()

public class RootController extends AppCompatActivity implements

#Override
public void setContentView(int layoutResID) {
rootView = getLayoutInflater().inflate(R.layout.root_controller, null);
drawer = (DrawerLayout)rootView.findViewById(R.id.drawer_layout);
FrameLayout frameLayout = (FrameLayout) drawer.findViewById(R.id.main_content);

nav.setBackgroundColor(ColorDelegate.getNavColor());
Menu menu = nav.getMenu();
// set navigation listener
nav.setNavigationItemSelectedListener(this);

Try with this in your Activity:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = getWindow();
String dynamicColor = "#99000000";
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); /*You were missing this*/
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(Color.parseColor(dynamicColor));
}
I'm planning to implement a navigation bar to let users navigate to different activites.
But here's the problem,
I've found plenty articles about creating a navigation drawer but it seems doesn't work for me , because my UI doesn't have any titlebar.
And what i actually want is to call up the navigation drawer whenever users press on a button near to the navigation drawer.
Is there any possible way to do this ?
It is very simple.
Here is your main activity's layout, activity_main.xml:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:layout_height="match_parent">
<FrameLayout
android:animateLayoutChanges="true"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
tools:ignore="MergeRootFrame" />
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/drawer_list_header"
app:menu="#menu/navigation"/>
</android.support.v4.widget.DrawerLayout>
And here's your MainActivity:
public class MainActivity extends AppCompatActivity {
NavigationView navigationView;
DrawerLayout drawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.navi_1:
// on 1st item in the menu, do something
break;
case R.id.navi_2:
// on 2nd item in the menu, do something
break;
}
drawerLayout.closeDrawers();
return false;
}
});
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
}
// [...]
private void openDrawer() {
if (!drawerLayout.isDrawerOpen(navigationView)) {
drawerLayout.openDrawer(navigationView);
}
}
private void closeDrawer() {
if (drawerLayout.isDrawerOpen(navigationView)) {
drawerLayout.closeDrawers();
}
}
}
Now you can open the drawer with openDrawer() and close it with closeDrawer().
A sample navigation.xml file which is located under the menu dir in the res (resources) folder:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="#+id/navi_1"
android:checked="true"
android:icon="#drawable/ic_android"
android:title="First item"/>
<item
android:id="#+id/navi_2"
android:icon="#drawable/ic_android"
android:title="Second item"/>
</group>
</menu>
Sample drawer_list_header.xml file, located under the layout dir in the res folder:
<?xml version="1.0" encoding="utf-8"?>
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/list_header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="fitXY"
android:adjustViewBounds="true"
android:paddingBottom="8dp"
android:src="#drawable/list_header_final">
</ImageView>
Here are some notes:
You have to declare a menu file for the drawer, see app:menu="#menu/navigation" in the layout file.
You might want to declare a header layout, which is displayed over the menu elements in the drawer, see app:headerLayout="#layout/drawer_list_header".
The drawer can be opened by a fling-like action from the edge of the screen. To prevent the users from doing that, you might want to lock/unlock your drawer on action using drawerLayout.setDrawerLockMode(...);, see the documentation for details.
Also note that in order to use NavigationView, you'll need the latest design support lib by adding the dependency to your module's gradle file: compile 'com.android.support:design:22.2.0'.
See more about it here.
Yes you can implement DrawerLayout with out ActionBar. You can manually open and close the DrawerLayout like
drawerLayout.openDrawer(Gravity.LEFT);
drawerLayout.closeDrawer(Gravity.LEFT);
Is it possible to add a circular icon like this to a transparent Toolbar (styled like an action bar), and maintain its coloring?
EDIT: this icon will be right aligned on the toolbar, similar to where you would see the three dot menu icon in most apps.
You want to inflate a menu for the toolbar, set the background to transparent, inflate the menu with the icon.
Activity with the Toolbar
public class MainActivity extends ActionBarActivity {
Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// getSupportActionBar().hide();
toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle("Hello World");
toolbar.inflateMenu(R.menu.menu_main);
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
int id = item.getItemId();
if (id == R.id.icon) {
// Your action here
Toast.makeText(getApplicationContext(), "Clicked", Toast.LENGTH_SHORT).show();
return true;
}
return false;
}
});
}
}
activity layout
<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=".MainActivity"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_height="56dp"
android:layout_width="match_parent"
app:theme="#style/ThemeOverlay.AppCompat.Light"
android:elevation="5dp"
android:background="#android:color/transparent" />
</LinearLayout>
Menu
<menu xmlns:android="http://schemas.android.com/apk/res/android"

android:title="Icon Title"
android:icon="#drawable/ic_launcher"
android:orderInCategory="100"
app:showAsAction="always" />
</menu>
I'm trying to create simple application using android-support-v7:21 library.
Code snippets:
MainActivity.java
public class MainActivity extends ActionBarActivity {
Toolbar mActionBarToolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
mActionBarToolbar.setTitle("My title");
setSupportActionBar(mActionBarToolbar);
}
activity_main.xml
<LinearLayout
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"
android:fitsSystemWindows="true"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_actionbar"
android:background="#null"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:fitsSystemWindows="true" />
</LinearLayout>
But instead of "My title" on Toolbar %application name% is shown.
Seems like setTitle method has no effect.
I would like to show "My title".
UPD:
Before, styles.xml was:
<style name="AppTheme" parent="Theme.AppCompat">
<item name="windowActionBar">false</item>
</style>
So, I thought that actionbar is not used.
I add NoActionBar to style parent:
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
<item name="windowActionBar">false</item>
</style>
But the problem is not resolved.
Found the solution:
Instead of:
mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
mActionBarToolbar.setTitle("My title");
setSupportActionBar(mActionBarToolbar);
I used:
mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
setSupportActionBar(mActionBarToolbar);
getSupportActionBar().setTitle("My title");
And it works.
For anyone who needs to set up the title through the Toolbar some time after setting the SupportActionBar, read this.
The internal implementation of the support library just checks if the Toolbar has a title (not null) at the moment the SupportActionBar is set up. If there is, then this title will be used instead of the window title. You can then set a dummy title while you load the real title.
mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
mActionBarToolbar.setTitle("");
setSupportActionBar(mActionBarToolbar);
later...
mActionBarToolbar.setTitle(title);
The above answer is totally true but not working for me.
I solved my problem with the following things.
Actually My XML is like that:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/confirm_order_mail_layout"
android:layout_width="match_parent"
android:layout_height="fill_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/confirm_order_appbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/confirm_order_list_collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.v7.widget.Toolbar
android:id="#+id/confirm_order_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
I have tried all the option and after all I just removed CollapsingToolbarLayout because of i do not need to use in that particular XML So My Final XML is like:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/confirm_order_mail_layout"
android:layout_width="match_parent"
android:layout_height="fill_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/confirm_order_appbar_layout"
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/confirm_order_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
Now you have to use setTitle() like above answer:
mActionBarToolbar = (Toolbar) findViewById(R.id.confirm_order_toolbar_layout);
setSupportActionBar(mActionBarToolbar);
getSupportActionBar().setTitle("My Title");
Now If you want to use CollapsingToolbarLayout and Toolbar together then you have to use setTitle() of CollapsingToolbarLayout
CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.confirm_order_mail_layout);
collapsingToolbarLayout.setTitle("My Title");
May it will helps you. Thank you.
Simply you can change any activity name by using
Activityname.this.setTitle("Title Name");
Try this, you can define title directly in XML:
<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="some title"
app:popupTheme="#style/AppTheme.PopupOverlay">
To set the title for each Navbar fragment title
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
myView = inflater.inflate(R.layout.second_layout, container, false);
getActivity().setTitle("title");
return myView;
}
Try this .. this method works for me..!! hope it may help somebody..!!
<android.support.v7.widget.Toolbar
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/my_awesome_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" >
<TextView
android:id="#+id/toolbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:singleLine="true"
android:text="Toolbar Title"
android:textColor="#android:color/white"
android:textSize="18sp"
android:textStyle="bold" />
</android.support.v7.widget.Toolbar>
To display logo in toolbar try the below snippet.
// Set drawable
toolbar.setLogo(ContextCompat.getDrawable(context, R.drawable.logo));
Let me know the result.
getSupportActionBar().setTitle("Your Title");
Please see https://code.google.com/p/android/issues/detail?id=77763. Apparently it is supposed to work like that. Once you call the setSupportActionBar() method call, it then is the responsibility of the ActionBar delegate to route the call to the correct view.
It's not just about .setTitle
more methods of Support Toolbar (Appcompat v7) in onCreate works only with
getSupportActionBar().method()
and don't work with mToolbar.method()
examples:
getSupportActionBar().setTitle("toolbar title");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
though next methods works fine without getSupportActionBar() in onCreate
mToolbar.setVisibility(View.VISIBLE);
mToolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//
}
Problem only with onCreate event, you still can use mToolbar.setTitle() later instead of annoying getSupportActionBar().setTitle(), for example if you add this in onCreate it will work (because it will be executed later, after onCreate)
mHandler.post(new Runnable() {
#Override
public void run() {
mToolbar.setTitle("toolbar title");
}
});
I prefer to use this solution https://stackoverflow.com/a/35430590/4548520 than https://stackoverflow.com/a/26506858/4548520 because if you change title many times (in different functions) it's more comfortable to use mToolbar.setTitle() than longer getSupportActionBar().setTitle() one and you don't see annoying notification about null exception like with getSupportActionBar().setTitle()
For anyone who needs to set up the title through the Toolbar some time after setting the SupportActionBar (#sorianiv) AND your Toolbar is inside a CollapsingToolbarLayout, read this:
mToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.toolbar_layout);
Toolbar toolbar = findViewById(R.id.toolbar);
//toolbar.setTitle(""); // no need to do this
//mToolbarLayout.setTitle("Title"); // if you need an initial title, do this instead
setSupportActionBar(toolbar);
Then later,
mToolbarLayout.setTitle("New Title");
I tried to rename the toolbar from the fragment
It helped me, I hope to help someone else
Activity activity = this.getActivity();
Toolbar toolbar = (Toolbar) activity.findViewById(R.id.detail_toolbar);
if (toolbar != null) {
activity.setTitle("Title");
}
//toolbar.setTitle("Title"); did not give the same results
Screenshot:
Application title will not show as default title on every activity, you can insert different title on every activity. On your activity file bellow the onCreate just paste a single line to set title,
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setTitle("Your Title Here");
Just change the text "Your Title Here" to your text.
Simply use this in your adapter,
Where MainActivity is your AppCompactActivity.
Call it from anywhere.
((MainActivity) context).getSupportActionBar().setTitle(titles.get(position));
I made it work by using -
toolbar.post(new Runnable() {
#Override
public void run() {
toolbar.setTitle("My Title");
}
});
If you are using CollapsibleToolbarLayout along with Toolbar then you will need to set title in both the layouts
set your Toolbar as action bar in onCreate method
protected void setUpToolBar() {
if (mToolbar != null) {
((HomeActivity) getActivity()).setSupportActionBar(mToolbar);
mToolbar.setTitleTextColor(Color.WHITE);
mToolbar.setTitle("List Detail");
mToolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getActivity()
.getSupportFragmentManager().popBackStack();
}
});
((HomeActivity) getActivity()).getSupportActionBar()
.setDisplayHomeAsUpEnabled(true);
}
}
Later simply update title of toolbar using setTitle method
mToolbar .setTitle(productFromShoppingList.getProductName());
mCollapsingToolbar.setTitle(productFromShoppingList.getProductName());
I have a strange behaviour that may can help you.
This is working but it has no effect in onCreate only:
toolbar.setTitle("title");
Try to use this in onCreate:
yourActivityName.this.setTitle("title")
This can be done by setting the android:label attribute of your activity in the AndroidManifest.xml file:
<activity android:name="my activity"
android:label="The Title I'd like to display" />
And then add this line to the onCreate():
getSupportActionBar().setDisplayShowTitleEnabled(true);
Try this:
Xml Code
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="120dp"
android:id="#+id/tool_bar"
android:background="#color/tablayout"
android:theme="#style/ToolBarStyle"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name"
android:layout_gravity="center"
android:id="#+id/toolbar_title"
android:textSize="18sp"
android:textColor="#color/white"/>
</android.support.v7.widget.Toolbar>
Java Code
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.tool_bar);
toolbar_text = (TextView)findViewById(R.id.toolbar_title);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
toolbar.setLogo(R.drawable.ic_toolbar);
}
If your goal is to set a static string in the toolbar, the easiest way to do it is to simply set the activity label in AndroidManifest.xml:
<activity android:name=".xxxxActivity"
android:label="#string/string_id" />
The toolbar will get this string without any code. (works for me with v27 libraries.)
To change the title for each different activity
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pizza);
setTitle(getResources().getText(R.string.title));
}
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//custom toolbaar
getSupportActionBar().setTitle("Abhijeet");
}
}
Though not immediately relevant to this particular setup, I found that removing "CollapsingToolbarLayout" from my XML that was wrapping my toolbar inside of an AppBarLayout made everything work.
So, this:
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"
app:navigationIcon="#drawable/ic_arrow_back_white_24dp" />
</android.support.design.widget.AppBarLayout>
Instead of this:
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/collapsingToolbar"
android:minHeight="?attr/actionBarSize"
app:layout_scrollFlags="enterAlways|scroll|snap">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_height="?attr/actionBarSize"
app:navigationIcon="#drawable/ic_arrow_back_white_24dp" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
Then, I set the title in the activity's onCreate, before setSupportActionBar() is called.
Make sure you add this option:
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_TITLE);
The answer is in the documentation (which you can find here):
To use the ActionBar utility methods, call the activity's
getSupportActionBar() method. This method returns a reference to an
appcompat ActionBar object. Once you have that reference, you can call
any of the ActionBar methods to adjust the app bar. For example, to
hide the app bar, call ActionBar.hide().
That is the solution you actually found. Just thought of giving a reference to the official documentation (which apparently few tend to read).
In Kotlin you can do this:
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import androidx.appcompat.widget.Toolbar
class SettingsActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_settings)
val toolbar = findViewById<Toolbar>(R.id.toolbar)
setSupportActionBar(toolbar)
supportActionBar?.setDisplayHomeAsUpEnabled(true)
supportActionBar?.setTitle(R.string.title)
}
override fun onSupportNavigateUp() = true.also { onBackPressed() }
}
This is happening because you are using Toolbar and ActionBar both. Now as you want to use Toolbar as an action bar, the first thing you need to do is disable the decor provided action bar.
The easiest way is to have your theme extend from Theme.AppCompat.NoActionBar.
