Android force ActionBar inside of Toolbar on Landscape

Android force ActionBar inside of Toolbar on Landscape - android

The example code found on https://github.com/chrisbanes/cheesesquare results in my tablet to look like this:
However I want it to look like this :
Relevant xml code:
<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/main_content"
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="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
Relevant code in MainActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
final ActionBar ab = getSupportActionBar();
ab.setHomeAsUpIndicator(R.drawable.ic_menu);
ab.setDisplayHomeAsUpEnabled(true);
// ...
ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
if (viewPager != null) {
Adapter adapter = new Adapter(getSupportFragmentManager());
adapter.addFragment(new CheeseListFragment(), "Category 1");
adapter.addFragment(new CheeseListFragment(), "Category 2");
adapter.addFragment(new CheeseListFragment(), "Category 3");
viewPager.setAdapter(adapter);
}
//...
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
What do I have to change/add to the layout/code to make the toolbar contain the tabs ?

Toolbar is a FrameLayout. Put the tabs inside the Toolbar
<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/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.v7.widget.Toolbar>

Tab buttons do not appear under action bar

I want to add a TabLayout with three buttons. underneath my app bar.
I'm using this walk-through to add tab buttons (TabLayout) underneath my app bar.
The swipe and everything is working fine. The only problem is no button appears!
What is going wrong?
(I'm using support lib and design lib version 23.0.1)
I have checked these links and haven't been of any help for me:

How can i implement Collapsing layout with tabs without a list view?

i am working on a android project where i have to implement collapsing toolbar with tabs . Tabs should contain a normal Relative layout which has 4 textview.
I am successfully able to implement the collapsing toolbar but the problem is when ever i try to scroll upwards holding the tabs i have implemented collapse toolbar is not working. On the same tabs if i use a list view or Grid layout its working fine when i scroll. If i try to use Normal layout's such as Linear or Relative layout i am not able to scroll. is there any way i can fix this without list or grid layout?
below is my code for xml:

Try this
Step 1. main_activity.xml
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

FragmentActivity.java
public class FragmentActivity1 extends Fragment {
public FragmentActivity1()
{
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_fragment_activity1, container, false);
}
}
Step:3 take two other Fragment 2,3 and write code as above
Step:4 MainActivity.java
public class MainActivity extends AppCompatActivity {
private ViewPager pager;
private TabLayout tabLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolBar_hotel_detail);
setSupportActionBar(toolbar);
ViewCompat.setTransitionName(findViewById(R.id.app_bar_layout), "Extra Image");
CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout)
findViewById(R.id.collapsingToolBar_hotel_details); collapsingToolbarLayout.setContentScrimColor(ContextCompat.getColor(getApplicationContext(), R.color.colorPrimary));
collapsingToolbarLayout.setTitle("Collaps");
pager = (ViewPager) findViewById(R.id.viewPager);
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new FragmentActivity1());
adapter.addFragment(new FragmentActivity2());
adapter.addFragment(new FragmentActivity3());
pager.setAdapter(adapter);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(pager);
tabLayout.getTabAt(0).setText("Tab1");
tabLayout.getTabAt(1).setText("Tab2");
tabLayout.getTabAt(2).setText("Tab3");
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment) {
mFragmentList.add(fragment);
}
}
}

Strange Blank Line on TabbedView + ViewPager

I've done a tabbedView that hold a ListView in a fragment and i used an ActionToolbar on which I have disabled sliding
Now i see that my ListView is covered by a Blank Space that i do not even know how to name
How to delete it?
XML

OnCreateMethod of the Activity that contains my fragment
#Override

toolbar.setTitleTextColor(getResources().getColor(R.color.slider_tab));
AppBarLayout.LayoutParams params = (AppBarLayout.LayoutParams) toolbar.getLayoutParams();
params.setScrollFlags(0);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
vpPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(vpPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(vpPager);
setupTabIcons();
TabLayout.Tab tab= tabLayout.getTabAt(1);
tab.select();
}

DrawerToggle may not show up because NavigationIcon is not visible. You may need to call actionbar.setDisplayHomeAsUpEnabled(true);

The caret icon does not show up even though i am already calling the setDisplayHomeAsUpEnabled(true)
private ViewPager mViewPager;
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_page_tab);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(true);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
}
I am creating a page that contains Tabbed and Navigation activity
and this is my XML file

Setting title in main activity

I'm embarassed to post this question, but I'm trying for two hours to change title in my application's main activity and to, my surprise, no results. I tried:
setTitle();
getActionBar().setTitle()
getSupportActionBar().setTitle();
Everyone is writing about those above, but none of them works. Even more surprisingly - in the other activities and fragments it's all fine. Only in this one.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_beer);
Utils.checkGpsStatus(this);
Utils.checkNetworkStatus(this);
Location location = SmartLocation.with(this).location().getLastLocation();
if(location != null){
lat = location.getLatitude();
lng = location.getLongitude();
}
ViewPager viewPager = (ViewPager) findViewById(R.id.activity_main_activity_beer);
if (viewPager != null) {
setupViewPager(viewPager);
}
//viewPager.setOffscreenPageLimit(2);
//viewPager.setCurrentItem(1);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}

Try this
Extend your activity with extends AppCompatActivity.
Put below code in your onCreate method.
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setElevation(0);
getSupportActionBar().setTitle("Your Title");
Cheers!

This is the best practice to make your code compatible with latest devices because default actionbar is deprecated from Lollipop.
