I am using the app theme Theme.Black
in my app. In this theme the action bar is gray. How I can change color of my action bar? This is my attempt:
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="mytheme" parent="@android:style/Theme.Black" >
</style>
<style name="Widget.MyApp.ActionBar" parent="@android:style/Widget.ActionBar">
<item name="android:background">@android:color/black</item>
</style>
</resources>
However, it doesn't work. Any ideas?
This question is related to
android
android-layout
if you have in your layout activity_main
<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" />
you have to put
in your Activity this code
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
toolbar.setBackgroundColor(Color.CYAN);
}
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:actionBarStyle">@style/MyActionBar</item>
</style>
<style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#C1000E</item>
<item name="android:titleTextStyle">@style/AppTheme.ActionBar.TitleTextStyle</item>
</style>
<style name="AppTheme.ActionBar.TitleTextStyle" parent="@android:style/TextAppearance.StatusBar.Title">
<item name="android:textColor">#E5ED0E</item>
</style>
I have Solved Using That.
Just simply go to res/values/styles.xml file and edit the xml file to change the color of xml file .Here is the sample code
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
// below code is for changing the color of action bar
<item name="colorPrimary">"type your color code here. eg:#ffffff"</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
Hope it will help you...
If you use Android default action bar then. If you change from java then some time show previous color.
Example
Then your action bar code inside "app_bar_main". So go inside app_bar_main.xml and just add Background.
Example
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout
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="#33691e" <!--use your color -->
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main1" />
ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable("COLOR"));
it worked for me here
Updated code:
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.your_color)));
Maybe this can help you also. It's from the website:
http://nathanael.hevenet.com/android-dev-changing-the-title-bar-background/
First things first you need to have a custom theme declared for your application (or activity, depending on your needs). Something like…
<!-- Somewhere in AndroidManifest.xml -->
<application ... android:theme="@style/ThemeSelector">
Then, declare your custom theme for two cases, API versions with and without the Holo Themes. For the old themes we’ll customize the windowTitleBackgroundStyle attribute, and for the newer ones the ActionBarStyle.
<!-- res/values/styles.xml -->
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="ThemeSelector" parent="android:Theme.Light">
<item name="android:windowTitleBackgroundStyle">@style/WindowTitleBackground</item>
</style>
<style name="WindowTitleBackground">
<item name="android:background">@color/title_background</item>
</style>
</resources>
<!-- res/values-v11/styles.xml -->
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="ThemeSelector" parent="android:Theme.Holo.Light">
<item name="android:actionBarStyle">@style/ActionBar</item>
</style>
<style name="ActionBar" parent="android:style/Widget.Holo.ActionBar">
<item name="android:background">@color/title_background</item>
</style>
</resources>
That’s it!
ActionBar actionBar;
actionBar = getActionBar();
ColorDrawable colorDrawable = new ColorDrawable(Color.parseColor("#93E9FA"));
actionBar.setBackgroundDrawable(colorDrawable);
onclick buttons c2
to fetch and change the color of action bar and notification bar according to button's background, hope this helps
int color = c2.getBackground()).getColor();
int colorlighter = -color * 40 / 100 + color;
getWindow().setNavigationBarColor(colorlighter);
getWindow().setStatusBarColor(colorlighter);
ActionBar bar = getSupportActionBar();
bar.setBackgroundDrawable(new ColorDrawable(color));
colorlighter
is used to set color of notification bar a little lighter than action bar
color
is the background color of button c2
, according to which we change our color.
