I am trying have my android app work on multiple versions and have ran into a jam with API 19. I have a toolbar that is not clickable. The toolbar shows but clicking is not firing. The app works fine for API 21 and 23. I also notice that the view pager is also not clickable but the swipe works. Not sure what I am doing wrong...
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:id="#+id/toolbarGeneral"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="#style/AppTheme.AppBarOverlay"
app:popupTheme="#style/AppTheme.PopupOverlay" />
Style:
<resources>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" >
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="windowActionBarOverlay">false</item>

MainActivity:
public class MasterActivity : AppCompatActivity, View.IOnClickListener//, Android.Support.V4.App.FragmentActivity
{
//private XmppClient _xmppClient;
private ViewPager _mViewPager;
//private bool _shouldImportContact;

{
base.OnCreate(bundle);
_facebookInfo = new FacebookInfo();
_facebookCRUD = new CRUDRepository<FacebookInfo>();
_fragmentPos = Intent.GetIntExtra("FragmentPos", 0);
_dbConnection = SQLiteHelper.GetConnection();
try
{
_context = this;
SetContentView(Resource.Layout.Master); //Set view the Master view
Toolbar.Toolbar toolbar = FindViewById<Toolbar.Toolbar>(Resource.Id.toolbar);
this.SetSupportActionBar(toolbar);
_mViewPager = FindViewById<ViewPager>(Resource.Id.viewPager);
_mViewPager.Adapter = new MasterAdapter(base.SupportFragmentManager, _masterFragments, titleLabels);
_mViewPager.SetCurrentItem(_fragmentPos, true);
TabLayout tabLayout = FindViewById<TabLayout>(Resource.Id.tabs);
tabLayout.SetupWithViewPager(_mViewPager);
FloatingActionButton fab = FindViewById<FloatingActionButton>(Resource.Id.fab);
fab.SetOnClickListener(this);
//Create the pageChangeListener class so that the page selected is known
_pageChangeListener = new MasterPageChangeListener(this, _mViewPager);
_mViewPager.AddOnPageChangeListener(_pageChangeListener);
}
catch (Exception Ex)
{
var data = Ex.Message;
}
}
OnPrepareOptionsMenu and OnCreateOptionsMenu:
public override bool OnPrepareOptionsMenu(IMenu menu)
{
if (_pageChangeListener.tabPosition == 0)
_editMenu.SetVisible(true);
else if (_pageChangeListener.tabPosition == 1 || _pageChangeListener.tabPosition == 2)
_editMenu.SetVisible(false);
return base.OnPrepareOptionsMenu(menu);
}
public override bool OnCreateOptionsMenu(IMenu menu)
{
base.OnCreateOptionsMenu(menu);
var inflater = MenuInflater;
inflater.Inflate(Resource.Menu.menu, menu);
_editMenu = menu.FindItem(Resource.Id.action_add);
return true;
}
The issue directly relates to this:
1) You need to define app: correctly to xmlns:app="http://schemas.android.com/apk/res-auto" instead of xmlns:app="http://schemas.android.com/apk/lib-auto"
2) You need to change the word app:layout_behaviour to app:layout_behavior
Feel free to edit your original question with the respective code so this answer makes more sense! (As more source code was revealed in a PM)

I am developing an app to display details about movie/tv shows. When opening the movie from search results it opens correctly. Then I add the movie to my collection, turns to MainActivity where all my movies are listed. Selecting the same movie, but now the entire AppBarLayout is hidden! I don't get any exceptions of any kind, in debug I see that it is visible, but has height of 0. Why is this happening?
I have a method that collapses the CollapsingToolbarLayout if no banner image is found, but this is not the case here. It should anyhow have a toolbar with title when collapsed, and expand on scroll.

Both the SearchActivitiy and DetailActivity uses AppTheme.NoActionBar. MainActivity uses AppTheme. I now noticed that when opening a movie from SearchActivity it is showing correctly, but if I press back (to search) and then opens the same movie again, it does not show correctly.
I had some suspicion that it whould be this line in the SearchActivity that caused the trouble, but it was not:
getSupportActionBar().hide();
It seems that it is only after using the SearchActivity that the DetailActivity does not show correctly. All of my other example data in MainActivity opens correctly in DetailActivity, until i have used the SearchActivity. Even some of the movies that I have not searched for.
Sorry if this question grew to be to long/detailed, but I often see that people are asking for more details, so I chose to include as much relevant info as I thought was necessary.
Please let me know if you need any more info?
I figured it out!
I am using Ion for image loading, and had a callback method "collapseAppBarOnError":
private FutureCallback<ImageView> collapseAppBarOnError() {
return new FutureCallback<ImageView>() {
#Override
public void onCompleted(Exception e, ImageView result) {
stopLoading();
if (e != null && !(e instanceof CancellationException)) {//TODO: Denne vil ikke funke om errorDrawable ligger i cache?
collapse();
} else if (result != null && result.getDrawable() != null && !result.getDrawable().equals(getDrawable(R.drawable.ic_movie_white_48dp))) {
expand();
}
}
};
}
It was the "else if" in the callback method that caused the trouble. Sorry, for this was impossible for you guys to see when I had not postet all my code.
It turns out that it actually had nothing to do with the SearchActivity, the error was also happening if I opened a movie I already had in my collection two times or more, even if not using the search! It worked correctly the first time, but not the following times.
In the log, I have
NullPointerException : Attempt to invoke virtual method 'void
android.app.ActionBar.setDisplayShowTitleEnabled(boolean)' on a null
object reference.
Here is my following code :
public class MatchesActivity extends Activity implements ActionBar.OnNavigationListener {
private ActionBar actionBar;
private ArrayList<SpinnerNavItem> navSpinner;
private TitleNavigationAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_matches);
actionBar=getActionBar();
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
navSpinner = new ArrayList<SpinnerNavItem>();
navSpinner.add(new SpinnerNavItem("Botola Pro",R.drawable.ic_menu_camera));
navSpinner.add(new SpinnerNavItem("Coupe du trone",R.drawable.ic_menu_camera));
adapter = new TitleNavigationAdapter(getApplicationContext(),navSpinner);
actionBar.setListNavigationCallbacks(adapter,this);
}
#Override
public boolean onNavigationItemSelected(int itemPosition, long itemId){
return false;
}
}
here is my styles.xml and my stylesv21.xml :
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>

</style>
</resources>
To get you started, here's some pointers. Toolbar is the new ActionBar. You can define any custom Toolbar layout you want from XML.
For a Spinner, for example, save this as toolbar_spinner.xml.
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimaryDark"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Dark"
>
<Spinner
android:id="#+id/spinner_nav"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</android.support.v7.widget.Toolbar>
Now, you can simply include that Toolbar layout into your Activity. (Make sure that Activity uses a Theme without a Toolbar like Theme.AppCompat.NoActionBar)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<include
android:id="#+id/toolbar"
layout="#layout/toolbar_spinner" />
<!-- Activity content here -->
</LinearLayout>
Then, you can start off your Activity class like so
public class SpinToolbarActivity extends AppCompatActivity {
private Toolbar mToolbar;
private Spinner mSpinner;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_spintoolbar);
mToolbar = (Toolbar) findViewById(R.id.toolbar);
mSpinner = (Spinner) findViewById(R.id.spinner_nav);
if (mToolbar != null) {
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
}
// TODO: add items to mSpinner using an Adapter
}
}
I'm developing an app in Android and I'm having problem with implementing the ActionBar in a Fragment.
Here's the code of my Fragment:
public class TopicListFragment extends ListFragment {
private LinkedList<Topic> mTopics;
private static final String TAG = "TopicListFragment";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
mTopics = TopicLab.get(getActivity()).getTopics();
ArrayAdapter<Topic> adapter = new TopicAdapter(mTopics);
setListAdapter(adapter);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
Log.d(TAG, "Menu created");
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.fragment_topic_list, menu);
}
And here's the XML file for the meny layout:
<?xml version="1.0" encoding="utf-8"?>
<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" >
<item android:id="#+id/menu_item_new_topic"
android:icon="#android:drawable/ic_menu_add"
android:title="#string/new_topic"
app:showAsAction="ifRoom"></item>
</menu>
When I run the app the ActionBar doesn't show and if I press the menù button from my smartphone, it appears in an ugly botton line with only the title.
As you can see in the Fragment class, I have inserted a line of debug, but it print the message only when I press the menù button but not when the Activity is created.
What can I do to fix it? Every answer will be really appreciated! Thank you!
EDIT----
As asked this is the styles.xml file
<resources>
<!-- Base application theme. -->
<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>
</resources>
Put this code in xml file
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
And below code in activity which holds fragment
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
}
And in your style add
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
Long time after, here is a safe option if you getting a gap in the actionbar testing with the old versions:
final RelativeLayout mainLayout = view.findViewById(R.id.main_layout);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
Rect rectangle = new Rect();
Window window = activity.getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(rectangle);
mainLayout.setPadding(0, rectangle.top, 0, 0);
}
Background
I have an activity in my app that has a toolbar as the actionBar, and it also has an actionMode, for multi-selection of items.
The problem
Every time I close the actionMode, there is a "jump" between the two modes, so I can see both the toolbar and the actionMode.
Maybe I'm just doing it wrong, but I remember it worked fine in the past.
Here's how it looks like using the snippet code I've made:
What I've tried
This is a snippet of the code I've used. To test it, run the app, wait a moment for the actionMode to appear, and then either press the back button, or press the button on the actionMode. Do note that all classes that I use are of the support library (when available).
MainActivity.java
public class MainActivity extends AppCompatActivity {
protected ActionMode.Callback _actionModeCallback;
protected ActionMode _actionMode;
Toolbar _toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
_toolbar = (Toolbar) findViewById(R.id.activity_app_list__toolbar);
setSupportActionBar(_toolbar);
_actionModeCallback = new ActionMode.Callback() {
#Override
public boolean onPrepareActionMode(final ActionMode mode, final Menu menu) {
return false;
}
#Override
public void onDestroyActionMode(final ActionMode mode) {
_toolbar.setVisibility(View.VISIBLE);
_actionMode = null;
}
#Override
public boolean onCreateActionMode(final ActionMode mode, final Menu menu) {
_toolbar.setVisibility(View.GONE);
return true;
}
#Override
public boolean onActionItemClicked(final ActionMode mode, final MenuItem item) {
mode.finish();
return true;
}
};
//
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
_actionMode = startSupportActionMode(_actionModeCallback);
}
}, 2000);
}
}

The question
Why is this happenning? How can I fix it?
Is this a known bug, perhaps?
What you're looking for is the ACTION_MODE_OVERLAY flag. In your Activity.onCreate() method, add the following before the call to super.onCreate():
#Override
protected void onCreate(Bundle savedInstanceState) {
supportRequestWindowFeature(Window.FEATURE_ACTION_MODE_OVERLAY);
super.onCreate(savedInstanceState);
// other stuff...
}
The same as described by #Kevin Coppock can also be achieved by adding <item name="windowActionModeOverlay">true</item> in your AppTheme.
The theme could look like this:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat">
<!-- Customize your theme here. -->.
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="preferenceTheme">#style/PreferenceThemeOverlay</item>
<item name="colorPrimary">#FF0288D1</item>
<item name="windowActionModeOverlay">true</item>
</style>
I want to add ToolBar in PreferenceActivity in my android application. I wrote the following code.
public class SettingsActivity extends PreferenceActivity {
SendSMS sms;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.settings);
LinearLayout root = (LinearLayout)findViewById(android.R.id.list).getParent().getParent().getParent();
android.support.v7.widget.Toolbar bar = (android.support.v7.widget.Toolbar) LayoutInflater.from(this).inflate(R.layout.action_bar_setting, root, false);
root.addView(bar, 0);
bar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});
}
This worked perfectly in my android Kitkat phone API 19 but force closed in API level 10 i.e. gingerbread. Please suggest me.
You need a layout that contains a Toolbar, and a ListView with android:id="#android:id/list"
activity_settings.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/content_frame"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
SettingsActivity.java
public class SettingsActivity extends PreferenceActivity {
private AppCompatDelegate mDelegate;
#Override
protected void onCreate(Bundle savedInstanceState) {
getDelegate().installViewFactory();
getDelegate().onCreate(savedInstanceState);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
setSupportActionBar((Toolbar) findViewById(R.id.toolbar));
addPreferencesFromResource(R.xml.preferences);
...
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
getDelegate().onPostCreate(savedInstanceState);
}
#Override
public void setContentView(#LayoutRes int layoutResID) {
getDelegate().setContentView(layoutResID);
}
#Override
protected void onPostResume() {
super.onPostResume();
getDelegate().onPostResume();
}
#Override
protected void onStop() {
super.onStop();
getDelegate().onStop();
}
#Override
protected void onDestroy() {
super.onDestroy();
getDelegate().onDestroy();
}
private void setSupportActionBar(#Nullable Toolbar toolbar) {
getDelegate().setSupportActionBar(toolbar);
}
private AppCompatDelegate getDelegate() {
if (mDelegate == null) {
mDelegate = AppCompatDelegate.create(this, null);
}
return mDelegate;
}
...
}
Check out my fully working example:
activity_settings.xml
SettingsActivity.java
Reference from the Android team: AppCompatPreferenceActivity
Try:
public class SettingsActivity extends AppCompatPreferenceActivity {
.....
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setupActionBar();
/* getFragmentManager().beginTransaction()
.replace(android.R.id.content, new GeneralPreferenceFragment())
.commit();
*/
//addPreferencesFromResource(R.xml.pref_general);
}
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);
}
}
app_bar_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
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>
I'm late but here's a small fix to the problem instead of writing tons of code or adding bulky libraries.
Go to AndroidManifest.xml and to your Preference Activity add the custom theme
<activity
android:name=".Dashboard.PreferencepActivity"
android:label="#string/title_activity_preference"
android:theme="#style/Pref"></activity>
Here's the custom theme added to the above #style/Pref
<style name="Pref" parent="Theme.AppCompat.DayNight.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
Hope it helps!
You can easily add toolbar from #android:style/Theme.Material.Light.DarkActionBar
In AndroidManifest.xml :
<activity
android:name=".activity.SettingsActivity"
android:theme="#style/SettingsTheme"
android:label="Settings"/>
In v21/styles.xml
<style name="SettingsTheme" parent="#android:style/Theme.Material.Light.DarkActionBar">
<item name="android:colorPrimary">#color/colorPrimary</item>
<item name="android:colorPrimaryDark">#color/colorPrimaryDark</item>
In v14/styles.xml for Back API support
<style name="SettingsTheme" parent="#android:style/Theme.Holo.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/ActionBar.V14.Movie.NoTitle</item>
Very easy and working well in my case by inflating custom toolbar.
In your java code do as below,
public class SettingsPrefActivity extends AppCompatPreferenceActivity {
// private static final String TAG = SettingsPrefActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setting up toolbar
getLayoutInflater().inflate(R.layout.toolbar_setting, (ViewGroup) findViewById(android.R.id.content));
Toolbar toolbar = findViewById(R.id.toolbar);
toolbar.setTitle("Settings");
setSupportActionBars(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
// load settings fragment
getFragmentManager().beginTransaction().replace(android.R.id.content, new MainPreferenceFragment()).commit();
}
}
and at your xml side code,add one preference category at the top do as below,
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
//put below line at the top of your xml preference layout screen..
<PreferenceCategory android:layout="#layout/toolbar_setting"></PreferenceCategory>
and in your layout resource folder toolbar_setting,
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="#dimen/appbar_elevation"
android:minHeight="?attr/actionBarSize"
android:popupTheme="#style/ThemeOverlay.AppCompat.Light"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
This method will not solve adding toolbar, but you can get the default ActionBar back for your settings page. Create a theme for settings activity, by inheriting from parent theme.
<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar.Bridge">
<!-- Customize your theme here. -->
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="AppTheme.Settings" parent="AppTheme">
<item name="windowNoTitle">false</item>
<item name="windowActionBar">true</item>
</style>
In AndroidManifest.xml set the android:theme
<activity
android:name=".Settings"
android:theme="#style/AppTheme.Settings" />
That is all.
Instead of:
public class PreferencesActivity extends Activity
Do this:
public class PreferencesActivity extends AppCompatActivity
