I'm trying to set the icon ShareActionProvider, need a solid white one instead of the semi transparent white one.
However setting in share_menu.xml and code doesn't work. Just wondering whether anyone has got workaround for this before extending the ShareActionProvider. (I'm using actionbarsherlock)
#Override
public void onCreateOptionsMenu(final Menu menu, final MenuInflater inflater) {
inflater.inflate(R.menu.share_menu, menu);
MenuItem actionItem = menu.findItem(R.id.share_action_provider);
ShareActionProvider actionProvider = (ShareActionProvider) actionItem.getActionProvider();
actionProvider.setShareIntent(mShareIntent);
// re-setting the icon as it's not being picked up from the menu xml file
actionItem.setIcon(R.drawable.ic_action_share);
super.onCreateOptionsMenu(menu, inflater);
}
share_menu.xml
<item android:id="#+id/share_action_provider"
android:showAsAction="ifRoom"
android:title="#string/share_with"
android:icon="#drawable/ic_action_share"
android:actionProviderClass="com.actionbarsherlock.widget.ShareActionProvider" />
Update:
Also tried setting it in the style, but no joy
<style name="Theme.MyApp" parent="Theme.Sherlock.Light">
<item name="actionModeStyle">#style/ActionModeStyle</item>
<item name="android:actionModeStyle">#style/ActionModeStyle</item>
</style>
<style name="ActionModeStyle" parent="Widget.Sherlock.ActionMode">
<item name="actionModeShareDrawable">#drawable/ic_action_share</item>
</style>
When I am looking to customize the action bar, usually the first place I look is the ActionBarSherlock themes and styles.
I found that the Sherlock theme uses the "actionModeShareDrawable" as found in theme.xml file.
Try changing your theme to include the "actionModeShareDrawable" item directly.
<style name="Theme.MyApp" parent="Theme.Sherlock.Light">
<item name="actionModeShareDrawable">#drawable/ic_action_share</item>
</style>
For AppCompat the changes to 2 styles are needed:
1)
<style name="MyAppTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<item name="actionBarWidgetTheme">#style/Theme.AppCompat.CustomShareIcon</item>
<item name="android:actionBarWidgetTheme">#style/Theme.AppCompat.CustomShareIcon</item>
</style>
In other words, specifiing attr:actionModeShareDrawable in your MyAppTheme is not what you really need, but it should be mentioned in your attr:actionBarWidgetTheme as following:
2)
<style name="Theme.AppCompat.CustomShareIcon" parent="#style/Theme.AppCompat">
<item name="actionModeShareDrawable">#drawable/abc_ic_menu_share_holo_dark</item> <!-- your icon goes here -->
</style>
UPDATE: Forget about the TRICKY way below, just sub-class ShareActionProvider, return null in onCreateActionView Method, and provide your own icon in menu.xml file, everything will be fine
===========================
I found a very tricky but none-ActionBarSherlock-specific way:
Sub-class ShareActionProvider, with just a little tweak:
#Override
public View onCreateActionView() {
View target = super.onCreateActionView();
ViewGroup viewGroup = (ViewGroup) LayoutInflater.from(context).inflate(R.layout.actionbutton_share, null);
ImageView overlay = (ImageView) viewGroup.findViewById(R.id.overlay);
ViewGroup container = (ViewGroup) viewGroup.findViewById(R.id.container);
container.addView(target);
container.getLayoutParams().width = overlay.getLayoutParams().width;
container.getLayoutParams().height = overlay.getLayoutParams().height;
return viewGroup;
}
Create a layout file (R.layout.actionbutton_share), which place the original view at top but transparent to user (Note the "android:alpha=0" part) :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#+id/container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:alpha="0" />
<ImageView
android:id="#+id/overlay"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_marginLeft="7dp"
android:layout_marginRight="7dp"
android:src="#drawable/yours_whatever_share_icon"
tools:ignore="ContentDescription" />
</RelativeLayout>
Use the hacked ShareActionProvider in your menu.xml file
vivimice's solution is good, but the icon of last used app for sharing becomes hidden too.
I did custom share icon as a common menu item without any ShareActionProvider, just in onOptionsItemSelected() method used this code:
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));
It creates not a popup menu, but a chooser dialog.
You can override the non-public attribute like this.
<style name="Theme.MyApp" parent="android:Theme.Holo">
<item name="*android:actionModeShareDrawalbe">#drawable/icon</item>
</style>
(*) means reference to the non-public resources in Android

I have been following the official documentation on how to create an app toolbar. The tutorial says that, after following the instructions,
"Your app now has a basic action bar. By default, the action bar
contains just the name of the app and an overflow menu."
Well, mine doesn't, it looks like this:
As you can see from this image, I've done some styling to get the colours as I want them, and I've added a menu item, just to see if it appeared correctly. I'll work out how to fix the colour of the icon later.
My problem is that, as you can see, the app title isn't centred vertically. It's too close to the top. This irritates me because, as far as I can tell, it should be centered automatically and I don't know why mine isn't, but I've nevertheless tried to fix this myself using styles, with absolutely no success. No style attributes seem to have any effect on the padding of just the Toolbar Title. I can add padding to the whole Toolbar, but that affects the menu item too, and I don't want it to.
My implementation looks like this:
activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="#+id/main_activity_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
style="#style/MyToolbarStyle"
app:theme="#style/MyToolbarTheme" />
</LinearLayout>
styles.xml:
<resources>
<!-- Base application theme. -->
<style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="MyToolbarStyle" parent="Base.Widget.AppCompat.Toolbar">
<item name="android:elevation">4dp</item>
<item name="android:background">#color/colorPrimary</item>
</style>
<style name="MyToolbarTheme" parent="Base.Widget.AppCompat.Toolbar">
<item name="android:textColorPrimary">#ffffff</item>
</style>
Ideally, if somebody could explain where I've gone wrong so that my application title isn't centered vertically, that'd be great, but if not, can somebody tell me how to add a margin or padding just to the application title in the toolbar so that I can attempt to centre it myself?
P.S. This isn't a duplicate of this question - that question deals with a more complex custom Toolbar. Mine is supposed to be the default implementation.
Update:
As requested, here's the code for my MainActivity.java file:
package com.example.samplescanner;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuInflater;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar MainActivityToolbar = (Toolbar) findViewById(R.id.main_activity_toolbar);
setSupportActionBar(MainActivityToolbar);
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_items, menu);
return super.onCreateOptionsMenu(menu);
}
}
I couldn't find the exact source of the issue from Base.Widget.AppCompat.Toolbar, but it alters the Gravity of the Toolbar. Inherit from ThemeOverlay.AppCompat.Dark.ActionBar instead:
<style name="MyTheme.ToolbarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="android:background">#color/colorPrimary</item>
<item name="android:elevation">4dp</item>
</style>
They use ThemeOverlay.AppCompat.ActionBar in the documentation you mentioned, but the Dark version should set the textColorPrimary attribute for you.
I'm trying to add share action to my toolbar. Toolbar is supposed to be orange (or transparent like in this case) with white text and icons, so I'm using this view as Toolbar:
<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_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
tools:ignore="UnusedAttribute" />
Also, this is how my app theme declaration looks like:
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
No matter how I change the style this is what I get:
How do I convince ShareActionProvider to get Light theme?
This is what i did and it worked. i wanted a white background in ShareActionProvider with it text being black
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:theme="#style/MainTheme"
app:layout_collapseMode="pin"/>
My theme
<style name="MainTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/md_white_1000</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:textColorPrimary">#ffffff</item>
<item name="android:textColorSecondary">#ffffff</item>
<item name="android:textColor">#color/md_black_1000</item>
<item name="listPopupWindowStyle">#style/PopupListStyle</item>
</style>
<style name="PopupListStyle" parent="#style/Widget.AppCompat.Light.ListPopupWindow">
<item name="android:popupBackground">#ffffff</item>
</style>
my solution is based on support library v7 , toolBar , ActionBarActivity , Android Studio
1- remove app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
2- make sure your base theme is Theme.AppCompat.Light.NoActionBar
3- go to original code of ShareActionProvider by typing "ShareActionProvider" anywhere in your code then import the v7 one then aim your mouse on it then (ctrl + left click)
4- copy the code in it and paste it in a new java file in you project directory
5- go to your own ShareActionProvider and remove this import if you have it import android.support.v7.appcompat.R
6- provide your own share icon because the default one is black
Drawable myDrawable = mContext.getResources().getDrawable(R.drawable.ic_share);
activityChooserView.setExpandActivityOverflowButtonDrawable(myDrawable);
7- go to your activity and remove the import you made in step 3 ( to use your own file )
8- go to your onCreateOptionsMenu it should be like this :
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem item = menu.findItem(R.id.menu_item_share);
mShareActionProvider = new ShareActionProvider(MainActivity.this);
MenuItemCompat.setActionProvider(item , mShareActionProvider);
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, "Hello World");
shareIntent.setType("text/plain");
mShareActionProvider.setShareIntent(shareIntent);
return true;
}
9- the last step is don't forget to edit your menu.xml
app:actionProviderClass=
"com.yourPackageName.ShareActionProvider" />
My issue concerns using fully custom ActionBar views (as it's necessary for how my customer wants the ActionBar to work). I've removed the logo, title, and everything else possible. However, the custom view for the ActionBar will not extend all the way across the screen.
I've tried the following (as a quick overview):
Dynamically removing aspects of the ActionBar (snippet below)
Removing the Options Menu in its entirety
Specifying in the Style/Theme to remove everything from the ActionBar
Here is a screenshot of my issue:
Here is the style: (as a side note, I originally kept the native ActionBar but removed most of it)
<!-- Customized App Theme -->
<style name="AppTheme2" parent="Theme.AppCompat.Light">
<!-- Let the actioBbar overlay the activity, ie activity is full screen -->
<item name="android:windowActionBarOverlay">true</item>
<!-- Set up the action bar styles -->
<item name="android:actionBarStyle">#style/ActionBarEmpty</item>
<!-- Remove the shadow under the actionBar -->
<item name="android:windowContentOverlay">#null</item>
<!-- Set the drawer icon to show up instead of the "Up" caret icon
<item name="android:homeAsUpIndicator">#drawable/ic_drawer</item>
<item name="homeAsUpIndicator">#drawable/ic_drawer</item>
-->
<!-- Support library compatibility -->
<item name="actionBarStyle">#style/ActionBarEmpty</item>
</style>
<!-- Final, empty Action Bar style | makes space for customized actionBar -->
<style name="ActionBarEmpty" parent="Widget.AppCompat.Base.ActionBar">
<!-- TODO: Add support versions -->
<item name="android:displayOptions">none</item>
<item name="android:background">#color/transparent</item>
<!-- Tested the below, does absolute nothing -->
<item name="android:layout_margin">0dp</item>
<item name="android:padding">0dp</item>
<item name="android:minWidth">0dp</item>
</style>
Here is the code in my Activity that concerns setting up the ActionBar:
// Initialize and set up the ActionBar
mActionBar = getActionBar();
mActionBar.setDisplayHomeAsUpEnabled(false);
mActionBar.setDisplayShowHomeEnabled(false);
mActionBar.setDisplayShowTitleEnabled(false);
mActionBar.setDisplayShowCustomEnabled(true);
// Set the actionBar layout initially to the simple one
mActionBar.setCustomView(mViewActionBarSimple);
Here is the view shown in the screenshot for the ActionBar:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="?android:actionBarSize"
android:background="#color/white">
<ImageButton
android:id="#+id/navButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="#dimen/padding_actionbar_icon"
android:paddingBottom="#dimen/padding_actionbar_icon"
android:paddingRight="#dimen/padding_actionbar_icon"
android:paddingEnd="#dimen/padding_actionbar_icon"
android:layout_marginLeft="#dimen/margin_actionbar_icon_left"
android:layout_marginStart="#dimen/margin_actionbar_icon_left"
android:src="#drawable/ic_drawer_normal"
android:background="?android:attr/selectableItemBackground"
/>
<TextView
android:id="#+id/textTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/margin_general"
android:layout_gravity="center"
android:textColor="#color/black"
android:textSize="#dimen/text_normal"
android:text="#string/garbage_fill_short"
/>
</LinearLayout>
In addition to trying to remove everything I could think of, I also tried to remove the options menu:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
return false;
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
// To remove the options menu - and make the custom actionBar take the full space -
// always return false
return false;
}
I'm running this on a Samsung Galaxy S4 with Android KitKat.
Thank you for reading this. Any help would be appreciated at this point.
Update: For anyone reading this, I don't know why it worked like this, but I came upon the problem after following the below answer. I surrounded the actionBar layout with a RelativeLayout [with the LinearLayout and its contents as the children], and the width/background fixed itself... The answer is still amazing as its very clear cut and absolutely removes the actionBar, while before I was still using it in some way.
Please try below for removing action bar content by creating base activity so you can refer in all your app & inflate custom action bar from layout
#SuppressLint("InlinedApi")
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
getSupportActionBar().hide();
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setHomeButtonEnabled(false);
actionBar.setIcon(new ColorDrawable(getResources().getColor(android.R.color.transparent)));
View homeIcon = findViewById(android.R.id.home);
// Hides the View (and so the icon)
if (homeIcon != null)
((View) homeIcon.getParent()).setVisibility(View.GONE);
overridePendingTransition(0, 0);
}
add custom view
#SuppressLint("InlinedApi")
#Override
public void setContentView(int layoutResID)
{
super.setContentView(R.layout.activity_base);
ViewGroup viewGroup = (ViewGroup) findViewById(R.id.container);
viewGroup.removeAllViews();
viewGroup.addView(getLayoutInflater().inflate(layoutResID, null));
// you can find action_bar layouts view & add listner
}
and customise XML containing custom action bar in activity_base.xml
<?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:layout_gravity="right"
android:orientation="vertical" >
<include layout="#layout/action_bar" />
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="right" />
</LinearLayout>
Where you want to use then extend this activity.
see the problem here, the grey checkbox leaves room from the top and bottom of the action bar:
styles.xml
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="CustomActionBarTheme" parent="Theme.Base.AppCompat.Light">
<item name="android:windowContentOverlay">#null</item>
<item name="android:actionButtonStyle">#style/ActionButtonStyle</item>
</style>
<!--<style name="ActionButtonStyle" parent="#android:style/Widget.Holo.Light.ActionButton">-->
<style name="ActionButtonStyle" >
<item name="android:height">#dimen/abc_action_bar_default_height</item>
<item name="android:layout_height">#dimen/abc_action_bar_default_height</item>
</style>
i set the item like so:
getMenuInflater().inflate(R.menu.submit_action, menu);
submit_action looks like:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/action_submit"
android:icon="#drawable/check"
app:showAsAction="always" />
</menu>
and finally, attached is the #drawable/check being used.
any idea how i can get the check to fill the actionbar?
The reason your icon doesn't fill the ActionBar is due to how the ActionMenuItemView measures the icon.
The ActionMenuItemView invokes a maximum size of 32dp when it sets the bounds for your icon
So, it makes so difference how large your image is, the system will always resize it.
any idea how i can get the check to fill the actionbar?
You should use a action layout for your MenuItem, a check mark icon with no background, and change the background color of the action layout parent as you see fit. Here's an example:
layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
style="?android:attr/actionButtonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#e8e8e8"
android:clickable="true"
android:contentDescription="#string/cd" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="#null"
android:scaleType="centerInside"
android:src="#drawable/ic_action_tick" />
</RelativeLayout>
MenuItem
<item
android:id="#+id/action_submit"
android:actionLayout="#layout/your_action_layout"
android:showAsAction="always"/>
Accessibility
It's important to make sure your MenuItem is accessible. Normally when you long press an item in the ActionBar a short Toast will display the content description for you, but when you're using a custom MenuItem it's up to you to implement this pattern. An easy way to do this is by using Roman Nurik's CheatSheet. If you're unsure how to use it, you should refer to my answer here that goes into much more detail on creating custom MenuItem layouts.
Alternatively
If you want to use that background color for every MenuItem you have, you could create a custom style and apply it using the android:actionButtonStyle attribute. Here's an example of that:
Your style
<style name="Your.ActionButton" parent="#android:style/Widget.Holo.Light.ActionButton">
<item name="android:background">#e8e8e8</item>
</style>
Your theme
<style name="Your.Theme" parent="#android:style/Theme.Holo.Light">
<item name="android:actionButtonStyle">#style/Your.ActionButton</item>
</style>
Results
Here's what I do with Icons in Android to get the sizing correct. You have an existing project with the res/drawable- folders. You have to put the correct Icon into the correct folder.
Start a new project wizard and when you get to the launcher icon put in the Icon you want to use in your existing project. finish the wizard. The wizard will make the various sizes of Icons for you. Then I manually copy the Icons from the res/drawable-xdpi res/drawable-ldpi etc to the corresponding folder on my existing project. Delete the new project it is no longer needed.
I want to display custom search in actionbar (I'm using ActionBarSherlock for that).
I got that:
But I want make custom layout (edittext field) to occupy the entire available width.
I've implemented custom layout as suggested here.
There is my custom layout search.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
style="?attr/actionButtonStyle"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_gravity="fill_horizontal"
android:focusable="true" >
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|fill_horizontal" >
<EditText
android:id="#+id/search_query"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="left|center"
android:background="#drawable/bg_search_edit_text"
android:imeOptions="actionSearch"
android:inputType="text" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right|center_vertical"
android:src="#drawable/ic_search_arrow" />
</FrameLayout>
</LinearLayout>
And in MyActivity:
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setIcon(R.drawable.ic_action_search);
LayoutInflater inflator = (LayoutInflater) this .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.search, null);
actionBar.setCustomView(v);
How can I make custom layout to occupy all the available width of actionBar?
Help, please.
There is a trick for this. All you have to do is to use RelativeLayout instead of LinearLayout as the main container. It's important to have android:layout_gravity="fill_horizontal" set for it. That should do it.
I struggled with this myself, and tried Tomik's answer.
However, this didn't made the layout to full available width on start, only when you add something to the view.
You'll need to set the LayoutParams.FILL_PARENT when adding the view:
//I'm using actionbarsherlock, but it's the same.
LayoutParams layout = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
getSupportActionBar().setCustomView(overlay, layout);
This way it completely fills the available space. (You may need to use Tomik's solution too).
This is how it worked for me (from above answers it was showing both default title and my custom view also).
ActionBar.LayoutParams layout = new ActionBar.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
// actionBar.setCustomView(view); //last view item must set to android:layout_alignParentRight="true" if few views are there
actionBar.setCustomView(view, layout); // layout param width=fill/match parent
actionBar.setDisplayShowCustomEnabled(true);//must other wise its not showing custom view.
What I noticed is that both setCustomView(view) and setCustomView(view,params) the view width=match/fill parent. setDisplayShowCustomEnabled (boolean showCustom)
The answers from Tomik and Peterdk work when you want your custom view to occupy the entire action bar, even hiding the native title.
But if you want your custom view to live side-by-side with the title (and fill all remaining space after the title is displayed), then may I refer you to the excellent answer from user Android-Developer here:
https://stackoverflow.com/a/16517395/614880
His code at bottom worked perfectly for me.
For example, you can define a layout file which contains a EditText element.
<?xml version="1.0" encoding="utf-8"?>
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/searchfield"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:inputType="textFilter" >
</EditText>
you can do
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionBar = getActionBar();
// add the custom view to the action bar
actionBar.setCustomView(R.layout.actionbar_view);
EditText search = (EditText) actionBar.getCustomView().findViewById(R.id.searchfield);
search.setOnEditorActionListener(new OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId,
KeyEvent event) {
Toast.makeText(MainActivity.this, "Search triggered",
Toast.LENGTH_LONG).show();
return false;
}
});
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM
| ActionBar.DISPLAY_SHOW_HOME);
}
There is an example in the launcher app of Android (that I've made a library out of it, here), inside the class that handles wallpapers-picking ("WallpaperPickerActivity") .
The example shows that you need to set a customized theme for this to work. Sadly, this worked for me only using the normal framework, and not the one of the support library.
Here're the themes:
styles.xml
<style name="Theme.WallpaperPicker" parent="Theme.WallpaperCropper">
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:colorBackgroundCacheHint">#null</item>
<item name="android:windowShowWallpaper">true</item>
</style>
<style name="Theme.WallpaperCropper" parent="#android:style/Theme.DeviceDefault">
<item name="android:actionBarStyle">#style/WallpaperCropperActionBar</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowActionBarOverlay">true</item>
</style>
<style name="WallpaperCropperActionBar" parent="#android:style/Widget.DeviceDefault.ActionBar">
<item name="android:displayOptions">showCustom</item>
<item name="android:background">#88000000</item>
</style>
value-v19/styles.xml
<style name="Theme.WallpaperCropper" parent="#android:style/Theme.DeviceDefault">
<item name="android:actionBarStyle">#style/WallpaperCropperActionBar</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
<style name="Theme" parent="#android:style/Theme.DeviceDefault.Wallpaper.NoTitleBar">
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
EDIT: there is a better way to do it, which works on the support library too. Just add this line of code instead of what I've written above:
getSupportActionBar().setDisplayShowCustomEnabled(true);
