How to change Toolbar layout after listitems selection in android activity

I have created an activity with toolbar and recyclerview,Implemented selection option for recyclerview, After selection of list items i need to update selected items count in toolbar.I'm trying to achieve this by using
#Override
public boolean onCreateActionMode(ActionMode actionMode, Menu menu) {
// Inflate a menu resource providing context menu items
MenuInflater inflater = actionMode.getMenuInflater();
inflater.inflate(R.menu.menu_cab_recyclerviewdemoactivity, menu);
return true;
}
Now after selecting recyclerview items extra actionbar adding above the toolbar,Here is screen http://screencast.com/t/UY2KSs9r

If you just want to update the count in the toolbar, you can just update the title,
final ActionBar ab = getSupportActionBar();
if(ab!=null)
ab.setTitle(stringVariable);
I'm not sure what else you want to do, so for now here is my answer.

First of all remove the default ActionBar
edit your style.xml
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme colors here. -->
<item name="colorPrimary">#color/primary</item>
<item name="colorPrimaryDark">#color/primary_dark</item>
<item name="colorAccent">#color/accent</item>
<!-- Disables the Default ActionBar -->
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
Then in your main_activity_layout.xml, remove any padding on the root RelativeLayout tag.
Next
<android.support.v7.widget.Toolbar
android:id="#+id/mainToolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageButton
android:id="#+id/main_settings_btn"
android:background="#drawable/ic_settings"
android:backgroundTint="#color/accent"
android:contentDescription="Copy"/>
<ImageButton
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_gravity="right"
android:layout_marginRight="10dp"
android:background="#drawable/ic_points"
android:backgroundTint="#color/accent"
android:contentDescription="Paste"/>
</android.support.v7.widget.Toolbar>
...... <your_code_here_possibly_recyclerview>
This solves your extra toolbar issue.
Next
private Toolbar toolbar; // Declaring the Toolbar Object
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.mainToolbar); // Attaching the layout to the toolbar object
setSupportActionBar(toolbar); // Setting toolbar as the ActionBar with setSupportActionBar() call
// Now whenever you want to update the title just change text in below
getSupportActionBar().setTitle("My title");
}

How to change the Text color of the action Bar using Material Theme

I override the BackGround Color of the ActionBar from the style.xml
This is the code:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppTheme" parent="android:Theme.Material.Light.DarkActionBar">
<item name="android:statusBarColor">#color/ColorPrimaryDark</item>
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
<!-- Action bar -->
<style name="MyActionBar" parent="android:Theme.Material.Light.DarkActionBar">
<item name="android:background">#color/ColorPrimary</item>
</style>
</resources>
The code from main activity is here :
public class MainActivity extends Activity {
private ActionBar mActionBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitles = firstItem.getTitle(); //setting the title of the first item
/**
* Action Bar customization
*/
mActionBar = getActionBar();
//Latest
mActionBar.setTitle(" Latest"); // set the first title
mActionBar.setDisplayHomeAsUpEnabled(true); // Enabling action bar app icon and behaving it as toggle button
mActionBar.setDisplayShowHomeEnabled(false); // hide tha app icon from the action bar
mActionBar.setHomeButtonEnabled(true);
}
The problem is that I can't see the text of the action bar if i set the color from style.xml . Futhermore i can't use things like :
<item name="android:textColorPrimary">#color/row_child_menu_title</item>
or
<item name="android:colorAccent">#color/row_child_menu_title</item>
the result is the same. The text is being disappeared and only the menu icons and the toggle icon are visible
Thanks in advance

Android How am I supposed to change size of actionbar settitle text?

I want to change my action bar title text size. How am I supposed to do it?
ActionBar actionBar = getSupportActionBar();
actionBar = getSupportActionBar();
actionBar.setLogo(R.drawable.tg_logo_new);
actionBar.setDisplayUseLogoEnabled(true);
actionBar.setDisplayShowHomeEnabled(true);
actionBar.show();
actionBar.setTitle("Header");

You can also do something like this ..
android.support.v7.app.ActionBar actionBar = getSupportActionBar();
actionBar.setTitle(Html.fromHtml(" <b> YOUR TITLE </b> "));
in fromHtml() you can use any tag instead <b>. you can also use <h2>,<h3>, .., <h6> if you want bigger size.
that's it
You can do it
b = getIntent().getExtras();
if (b != null) {
String Description = b.getString("Description");
android.support.v7.app.ActionBar actionBar = getSupportActionBar();
actionBar.setTitle(Html.fromHtml("<b>" +Description+ "</b>"));
}

Try this, will solve your issue:
<style name="Theme.YourTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/Theme.YourTheme.Styled.ActionBar</item>
</style>
<style name="Theme.YourTheme.Styled.ActionBar" parent="Theme.YourTheme">
<item name="android:titleTextStyle">#style/Theme.YourTheme.Styled.ActionBar.TitleTextStyle</item>
</style>
<style name="Theme.YourTheme.Styled.ActionBar.TitleTextStyle" parent="#android:style/Widget.TextView">
<item name="android:textSize">12sp</item>
</style>
It required API 11 and above

Customizing action bar in android shows default action bar first

I am new to android, while customizing action bar i noticed that first it shows old(default) action bar first then it shows customized action bar. Also I want to set text color for action bar title.
My code snippet is
public class MainActivity extends ActionBarActivity {
MenuItem searchItem;
SearchView searchView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActionBar ab = getSupportActionBar();
ab.setTitle("Modification"); ab.setIcon(R.drawable.ap);
ab.setBackgroundDrawable(new
ColorDrawable(Color.parseColor("#00AA00")));
ab.setSubtitle("Modification");
setContentView(R.layout.activity_main);
I think there must be some silly mistake.
Please help.

Try this one..
create a theme.xml as follows
<resources>
<!-- the theme applied to the application or activity -->
<style name="CustomActivityTheme" parent="#android:style/Theme.Holo">
<item name="android:actionBarStyle">#style/MyActionBar</item>
<!-- other activity and action bar styles here -->
</style>
<!-- style for the action bar backgrounds -->
<style name="MyActionBar" parent="#android:style/Widget.Holo.ActionBar">
<item name="android:background">#5477B1</item>
</style>
Then in your Androidmanifest.xml
mention this in application tag
<application
..
android:theme="#style/CustomActionBarTheme"
Good luck

try like this,
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar mActionBar = getActionBar();
mActionBar.setDisplayShowHomeEnabled(false);
mActionBar.setDisplayShowTitleEnabled(false);
LayoutInflater mInflater = LayoutInflater.from(this);
View mCustomView = mInflater.inflate(R.layout.custom_actionbar, null);
TextView mTitleTextView = (TextView) mCustomView.findViewById(R.id.title_text);
mTitleTextView.setText("My Own Title");
mActionBar.setCustomView(mCustomView);
mActionBar.setDisplayShowCustomEnabled(true);
}
or
Create a style for the action bar and use a custom background:
<resources>
<!-- the theme applied to the application or activity -->
<style name="CustomActivityTheme" parent="#android:style/Theme.Holo">
<item name="android:actionBarStyle">#style/MyActionBar</item>
<!-- other activity and action bar styles here -->
</style>
<!-- style for the action bar backgrounds -->
<style name="MyActionBar" parent="#android:style/Widget.Holo.ActionBar">
<item name="android:background">#drawable/background</item>
<item name="android:backgroundStacked">#drawable/background</item>
<item name="android:backgroundSplit">#drawable/split_background</item>
</style>
</resources>

Different style of Tabs (ActionBarSherlock)

I want to create two tabs with different styles. What I must do to get such result like in example?
Example:
And what I have now:
TabsActivity
public class TabsActivity extends SherlockFragmentActivity {
private TabsAdapter mTabsAdapter;
private ActionBar mActionBar;
private TabHost tabHost;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.l_maintab);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
BitmapDrawable bg = (BitmapDrawable)
getResources().getDrawable(R.drawable.bg_striped);
getSupportActionBar().setBackgroundDrawable(bg);
BitmapDrawable bgSplit = (BitmapDrawable)
getResources().getDrawable(R.drawable.bg_striped_split_img);
bgSplit.setTileModeXY(Shader.TileMode.REPEAT, Shader.TileMode.REPEAT);
getSupportActionBar().setSplitBackgroundDrawable(bgSplit);
}
final ActionBar bar = getSupportActionBar();
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
bar.setDisplayOptions(0, ActionBar.DISPLAY_USE_LOGO);
bar.setDisplayShowTitleEnabled(true);
bar.setDisplayShowHomeEnabled(true);
mTabsAdapter = new TabsAdapter(this, (ViewPager) findViewById(R.id.pager));
ActionBar.Tab events_tab = bar.newTab().setText("Events");
ActionBar.Tab volo_tab = bar.newTab().setText("Volunteers");
mTabsAdapter.addTab(events_tab, EventFragment.class, null);
mTabsAdapter.addTab(volo_tab, UserFragment.class, null);
bar.selectTab(bar.getTabAt(tabnum));
}
l_maintab.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</LinearLayout>

This is controlled by the background that you assign to the tab (usually through styles and themes). Create a style for the tab:
<style name="MyTabStyle" parent="Widget.Sherlock.ActionBar.TabView">
<item name="android:background">#drawable/my_tab_indicator</item>
</style>
I've extended the ActionBarSherlock style so that the only relevant override is the background attribute. In your theme definition, add these to your theme:
<item name="actionBarTabStyle">#style/MyTabStyle</item>
<item name="android:actionBarTabStyle">#style/MyTabStyle</item>
Then all you need to do is make a drawable resource for each state and include a state-list drawable resource for your background.
EDIT:
If you have two different tab styles:
<style name="MyTabStyle" parent="Widget.Sherlock.ActionBar.TabView">
<item name="android:background">#drawable/my_tab_indicator</item>
</style>
<style name="MyOtherTabStyle" parent="Widget.Sherlock.ActionBar.TabView">
<item name="android:background">#drawable/my_other_tab_indicator</item>
</style>
Make your app theme, then make a second one extending it:
<style name="MyAppTheme" parent="Theme.Sherlock...">
<!-- other theme attributes -->
<item name="actionBarTabStyle">#style/MyTabStyle</item>
<item name="android:actionBarTabStyle">#style/MyTabStyle</item>
</style>
<style name="MyAppTheme.Alternate">
<!-- Override just the tab style -->
<item name="actionBarTabStyle">#style/MyOtherTabStyle</item>
<item name="android:actionBarTabStyle">#style/MyOtherTabStyle</item>
</style>
In your Manifest, set android:theme="#style/MyAppTheme" in the <application> element. For Activities that need the second tab style, use android:theme="#style/MyAppTheme.Alternate" in the <activity> element.
