I'm trying to make a Settings activity in my current app that extends from AppCompatPreferenceActivity. I was able to achieve the desired screen but couldn't create a simple toolbar with back key on it. I've already tried using:
inflating custom toolbar
using getSupportActionBar().setDisplayHomeAsUpEnabled(true) of the AppCompatPreferenceActivity
Most of what I'm using came from this!.
I removed the fragment part of it due to the errors it was causing.
Also, I have NoActionBar theme.
So far, I have used this in one of my 'about' and 'help' preferences which work flawlessly:
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
if (getSupportActionBar() != null) {
getSupportActionBar().setTitle(getString(R.string.about));
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
UPDATE:
Got answer here
Yes when you use getSupportActionBar().setDisplayHomeAsUpEnabled(true); for toolbar it should work fine, your implementation seems to be right, but unless your debug or provide the entire code not all could find what the scenario is, also try checking this style.
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>

<!--<item name="android:windowContentOverlay">#null</item>-->
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="drawerArrowStyle">#style/MaterialDrawer.DrawerArrowStyle</item>
</style>
<!--use item name="drawerArrowStyle" if you are using dark primaryColor in your app, else remove it-->
<style name="MaterialDrawer.DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">false</item>
<item name="color">#android:color/white</item>
</style>
</resources>
toolbar = (Toolbar) findViewById(R.id.toolbar2);
setSupportActionBar(toolbar);
setTitle(getIntent().getExtras().getString("channe_name"));
toolbar.setSubtitle(getIntent().getExtras().getString("channe_name"));
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
and also make sure you have the same in xml as well declared

How add AndroidX Toolbar to PreferenceScreen
settings.xml
any
PrefsFragment.java
public class PrefsFragment extends PreferenceFragmentCompat {
#Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
setPreferencesFromResource(R.xml.settings, rootKey);
}
}
activity_settings.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
SettingsActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
Toolbar toolbar = findViewById(R.id.settings_toolbar);
setSupportActionBar(toolbar);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.settings_content, new PrefsFragment())
.commit();
}
I have tried:
In onCreate():
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setIcon(R.drawable.ic_settings);
getSupportActionBar().setLogo(R.drawable.ic_settings);
In manifest:
android:logo="#drawable/ic_settings"
android:icon="#drawable/ic_settings"
And nothing is working. No errors or anything but the icons just don't appear.
you can try this:
getSupportActionBar().setDisplayUseLogoEnabled(true);
UPDATE other way:
<style name="MyActionBarLogo" parent="#style/Widget.AppCompat.Light.ActionBar">
<item name="background">#color/mainColor500</item>
<item name="logo">#drawable/actionbar_logo</item>
<item name="displayOptions">useLogo</item>
</style>
And in your main styles:
<item name="actionBarStyle">#style/MyActionBarLogo</item>
UPDATE 2 third way you can create a toolbar in activity xml file like that:
<android.support.v7.widget.Toolbar
android:id="#+id/my_awesome_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
Set logo using method setLogo() and set toolbar as support actionBar like that:
Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);
I have a custom ActionBar layout which I want to use in almost all of my Activities.
The problem is the text doesn't appear.
This is how I use it in an Activity
android.support.v7.app.ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowCustomEnabled(true);
//getSupportActionBar().setDisplayOptions(android.support.v7.app.ActionBar.DISPLAY_SHOW_CUSTOM);
actionBar.setCustomView(R.layout.actionbar_theme);
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setTitle("Signup");
But the title "Signup" doesn't appear on the ActionBar..
The theme of the ActionBar
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/actionbar_theme_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_gravity="center"
android:textColor="#color/white" />
</RelativeLayout>
Does this mean that I can't just do setTitle("asdf")?
As of now you can use toolbar as ActionBar and that toolbar can have any custom layout you wish. Here is the reference link.
Declare this in activity xml
<android.support.v7.widget.Toolbar
android:id=”#+id/my_awesome_toolbar”
android:layout_height=”wrap_content”
android:layout_width=”match_parent”
android:minHeight=”?attr/actionBarSize”
android:background=”?attr/colorPrimary” />
Then in java code use
Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);
styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
for this to work perfectly your Activity should extends AppCompatActivit
This is not how it works. If you set a custom layout to your action bar, you need to change the textview of it like if it was a normal view.
If you are using this layout several time, keep a reference of your action bar or of the viewgroup.
ViewGroup actionBarLayout = (ViewGroup) getLayoutInflater().inflate(R.layout.your layout containing your text view,null);
mActionBar.setCustomView(actionBarLayout);
(TextView)findViewById(R.id.actionbar_theme_title).setText(...)
I've just added an Android Toolbar to an app I'm working on. The toolbar placement works correctly with the toolbar layout appearing at the top of the display. However, the toolbar is showing up as a blank colored bar...the App Title and Overflow Icon do not show up in the Toolbar. Any ideas on how to fix?
ToolbarActivity.java:
public abstract class ToolbarActivity extends ActionBarActivity {
private Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
toolbar.setTitle("app name");
}
}
toolbar.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark"
android:background="#color/ColorPrimary" >
</android.support.v7.widget.Toolbar>
menu_main.xml:
<menu 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"
tools:context=".MainActivity">
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:orderInCategory="100"
app:showAsAction="always" />
</menu>
style.xml:
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
<item name="colorPrimary">#color/ColorPrimary</item>
<item name="colorPrimaryDark">#color/ColorPrimaryDark</item>
</style>
EDIT: Ok so this needs to be set in a completely different way to work. I assumed (because I hadn't worked with the ToolBar much yet, that when using setActionBar(toolbar) it added the custom ToolBar to the content view automatically - but that wasn't the case.
So the big issue is that the ToolBar is never added to the current content view and hence will never be visible until you actually add the ToolBar to the current content view.
There are different approaches, but I'm only gonna show one of the them.
Instead of having a toolbar.xml file, you should add the ToolBar directly into the layout file of the Activity.
Here's an example of the Activity class and the XML to go together with the Activity:
MainActivity.java
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
if(toolbar != null) {
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("My custom toolbar!");
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
}
}
activity_main.xml
<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"
tools:context=".MainActivity">
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#android:color/holo_red_light"
android:minHeight="100dp">
</android.support.v7.widget.Toolbar>
</RelativeLayout>
Your styles.xml file is correct as it is.
It's important to note, that after setting your ActionBar to the custom ToolBar, you use the default methods for changing how the ActionBar looks like. For instance setting the title, should be set from getSupportActionBar().setTitle() and not from toolbar.setTitle().
Tutorial: http://www.viralandroid.com/2015/08/android-toolbar-example.html
styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
...
<!-- Customize your theme here. -->
</style>
layout file
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:minHeight="?attr/actionBarSize"
android:background="#2196F3"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.v7.widget.Toolbar>
java
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
In manifest, add the following...
<activity android:name=".Activity.ToolbarActivity"
android:label="#string/yourStringTitle"
/>
Hope this helps
I am using a custom actionbar view, and as you can see in the screenshot below, there is a blank gray space in the actionbar. I want to remove it.
What have I done:
res/values-v11/styles.xml

<item name="android:actionBarStyle">#style/ActionBarStyle</item>
<item name="actionBarStyle">#style/ActionBarStyle</item>

<!-- activities... etc -->
</application>
MainActivity
public void onCreate(Bundle bundle) {
super.onCreate(bundle);
ActionBar actionbar = getSupportActionBar();
actionbar.setDefaultDisplayHomeAsUpEnabled(false);
actionbar.setDisplayHomeAsUpEnabled(false);
actionbar.setDisplayShowCustomEnabled(true);
actionbar.setDisplayShowHomeEnabled(false);
actionbar.setDisplayShowTitleEnabled(false);
actionbar.setDisplayUseLogoEnabled(false);
actionbar.setHomeButtonEnabled(false);
// Add the custom layout
View view = LayoutInflater.from(this).inflate(R.layout.actionbar, null, false);
actionbar.setCustomView(view);
}
I have found a recent post, that is pointing out that there is an issue with the latest release. I have also updated ADT and SDK to Android 5.
Android ActionBar's custom view not filling parent
I don't know what should I do.
Edit (partial solution):
Not working on Android <= API 10.
Android Lollipop, AppCompat ActionBar custom view doesn't take up whole screen width
What have I changed:
Use the latest sdk version:
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="21" />
Add a toolbarStyle:
<style name="AppBaseTheme" parent="#style/Theme.AppCompat.Light">
<item name="android:actionBarStyle">#style/ActionBarStyle</item>
<item name="actionBarStyle">#style/ActionBarStyle</item>
<item name="android:toolbarStyle">#style/ToolbarStyle</item>
<item name="toolbarStyle">#style/ToolbarStyle</item>
</style>
<style name="ToolbarStyle" parent="#style/Widget.AppCompat.Toolbar">
<item name="contentInsetStart">0dp</item>
<item name="android:contentInsetStart">0dp</item>
</style>
If you are adding the Toolbar via XML, you can simply add XML attributes to remove content insets.
<android.support.v7.widget.Toolbar
xmlns:app="schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/primaryColor"
android:contentInsetLeft="0dp"
android:contentInsetStart="0dp"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
android:contentInsetRight="0dp"
android:contentInsetEnd="0dp"
app:contentInsetRight="0dp"
app:contentInsetEnd="0dp" />
try this:
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
View customView = getLayoutInflater().inflate(R.layout.main_action_bar, null);
actionBar.setCustomView(customView);
Toolbar parent =(Toolbar) customView.getParent();
parent.setPadding(0,0,0,0);//for tab otherwise give space in tab
parent.setContentInsetsAbsolute(0,0);
The left inset is caused by Toolbar's contentInsetStart which by default is 16dp.
Change this to align to the keyline.
Update for support library v24.0.0:
To match the Material Design spec there's an additional attribute contentInsetStartWithNavigation which by default is 16dp. Change this if you also have a navigation icon.
It turned out that this is part of a new Material Design Specification introduced in version 24 of Design library.
https://material.google.com/patterns/navigation.html
However, it is possible to remove the extra space by adding the following property to Toolbar widget.
app:contentInsetStartWithNavigation="0dp"
Before :
After :
I found an other resolution (reference appcompat-v7 ) that change the toolbarStyle ,following code:
<item name="toolbarStyle">#style/Widget.Toolbar</item>
<style name="Widget.Toolbar" parent="#style/Widget.AppCompat.Toolbar">
<item name="contentInsetStart">0dp</item>
</style>
Just add app:contentInsetStart="0dp" to the XML attribute of the toolbar.
<android.support.v7.widget.Toolbar
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="wrap_content"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
android:paddingLeft="0dp">
This should be good enough.
Just Modify your styles.xml
<!-- ActionBar styles -->
<style name="MyActionBar" parent="Widget.AppCompat.ActionBar">
<item name="contentInsetStart">0dp</item>
<item name="contentInsetEnd">0dp</item>
</style>
Only add app:contentInsetStart="0dp" to the toolbar remove that left space.
So your Toolbar definition look like this
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
app:contentInsetStart="0dp"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
and it look like this
Instead of adding a toolbar in the layout, you can set your custom view as shown below.
Toolbar parent = (Toolbar) customView.getParent();
parent.setContentInsetsAbsolute(0,0);
If you check the documentation of toolbar, by default it has style defined and there is an item contentInsetStart.
<item name="contentInsetStart">16dp</item>
If you want to override this padding then it can be done in two ways.
1.Override the style and add your own style with contentInsetStart and contentInsetEnd values
<style name="MyActionBar" parent="Widget.AppCompat.ActionBar">
<item name="contentInsetStart">0dp</item>
<item name="contentInsetEnd">0dp</item>
</style>
2.In XML you can directly define the contentInsetStart and contentInsetEnd values
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
android:layout_height="?attr/actionBarSize">
<!--Add your views here-->
</androidx.appcompat.widget.Toolbar>
Using AppCompatAcitivty you can use just by
Toolbar mToolbar = (Toolbar) findViewById(R.id.toolbar);
View logo = getLayoutInflater().inflate(R.layout.custom_toolbar, null);
mToolbar.addView(logo, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
mToolbar.setContentInsetsAbsolute(0,0);
You need to add this line app2:contentInsetStart="0dp" in your toolbar
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app2="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary"
app2:contentInsetStart="0dp"/>
this work for me
toolbar.setPadding(0,0,0,0);
toolbar.setContentInsetsAbsolute(0,0);
Setting "contentInset..." attributes to 0 in the Toolbar didn't work for me. Nilesh Senta's solution to update the style worked!
styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="actionBarStyle">#style/Actionbar</item>
<item name="android:titleTextStyle">#style/ActionbarTitle</item>
</style>
<style name="Actionbar" parent="Widget.AppCompat.ActionBar">
<item name="contentInsetStart">0dp</item>
<item name="contentInsetEnd">0dp</item>
</style>
java (onCreate)
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setDisplayUseLogoEnabled(false);
actionBar.setDisplayShowCustomEnabled(true);
ActionBar.LayoutParams layoutParams = new ActionBar.LayoutParams(
ActionBar.LayoutParams.MATCH_PARENT,
ActionBar.LayoutParams.MATCH_PARENT
);
View view = LayoutInflater.from(this).inflate(R.layout.actionbar_main, null);
actionBar.setCustomView(view, layoutParams);
In xml add these two attribute for Toolbar tag:
app:contentInsetEnd="0dp"
app:contentInsetStart="0dp"
and inside code add these lines:
// remove extra padding of toolbar
toolbar.setContentInsetsAbsolute(0, 0);
toolbar.setPadding(0, 0, 0, 0);
Tested on mobile and tablet devices both.
Kotlin
supportActionBar?.displayOptions = ActionBar.DISPLAY_SHOW_CUSTOM;
supportActionBar?.setCustomView(R.layout.actionbar);
val parent = supportActionBar?.customView?.parent as Toolbar
parent?.setPadding(0, 0, 0, 0)//for tab otherwise give space in tab
parent?.setContentInsetsAbsolute(0, 0)
I did not find a solution for my issue (first picture) anywhere, but at last I end up with a simplest solution after a few hours of digging. Please note that I tried with a lot of xml attributes like app:setInsetLeft="0dp", etc.. but none of them helped in this case.
Picture 1
the following code solved this issue as in the Picture 2
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//NOTE THAT: THE PART SOLVED THE PROBLEM.
android.support.design.widget.AppBarLayout abl = (AppBarLayout)
findViewById(R.id.app_bar_main_app_bar_layout);
abl.setPadding(0,0,0,0);
}
Picture 2
Create toolbar like this:
<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/menuToolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="0dp"
android:background="#color/white"
android:contentInsetLeft="10dp"
android:contentInsetRight="10dp"
android:contentInsetStart="10dp"
android:minHeight="?attr/actionBarSize"
android:padding="0dp"
app:contentInsetLeft="10dp"
app:contentInsetRight="10dp"
app:contentInsetStart="10dp"></android.support.v7.widget.Toolbar>
please follow this link for more - Android Tips
only adding android:padding="0dp" work for me
<android.support.v7.widget.Toolbar
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="60dp"
android:padding="0dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
ActionBar ab = getSupportActionBar();
ab.setDisplayShowHomeEnabled(true);
ab.setDisplayShowCustomEnabled(true);
setDisplayShowTitleEnabled(true);
View customView = getLayoutInflater().inflate(R.layout.activity_main,null); //here activity_main.xml is the GUI design file.
ab.setCustomView(customView);
Toolbar parent =(Toolbar) customView.getParent(); //use V7 Toolbar import
parent.setContentInsetsAbsolute(0, 0);
setPadding(5,0,0,0);
ab.setIcon(R.mipmap.ic_launcher);
You can just use relative layout inside toolbar view group in your xml file and adjust the positions of widgets as you require them for your use case.No need to create custom layout & inflate it and attach to toolbar. Once done in your java code use setContentInsetsAbsolute(0,0) with your toolbar object before setting it as support action bar in your layout.
It would be better to add a background item into the style of the app actionbar to consistent with the background color of the customized actionbar:
<item name="android:background">#color/actionbar_bgcolor</item>
After android 6.0, the actionbar even has a margin-right space and cannot be set. Add a right margin adjusting in the activity like this: (the view is the customized actionbar or a right button in it)
int rightMargin = Build.VERSION.SDK_INT>=Build.VERSION_CODES.M ? 0 : 8; // may the same with actionbar leftMargin in px
ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) view.getLayoutParams();
p.setMargins(p.leftMargin, p.topMargin, rightMargin, p.bottomMargin);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1){
p.setMarginEnd(rightMargin);
}
view.setLayoutParams(p);
The actionbar machenism is just supported after Android 3.0+ app. If we use a toolbar (of support lib v7) instead, we should layout it in each xml of each activity, and take care of the issue of overlapping with system status bar in the Android 5.0 or later device.
