Как изменить цвет status bar android studio

Well, Izhar’s solution was OK but personally, I try to avoid code that looks as this:

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
//Do what you need for this SDK
};

But I don’t like to duplicate code either. In your answer I have to add a line of code like below in all Activities:

setStatusBarColor(findViewById(R.id.statusBarBackground),getResources().getColor(android.R.color.white));

So, I took Izhar’s solution and used XML to get the same result:
Create a layout for the StatusBar status_bar.xml

<View xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="@dimen/statusBarHeight"
     android:background="@color/primaryColorDark"
     android:elevation="@dimen/statusBarElevation">

Notice the height and elevation attributes, these will be set in values, values-v19, values-v21 further down.

Add this layout to your activities layout using include, main_activity.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/Black" >

<include layout="@layout/status_bar"/>
<include android:id="@+id/app_bar" layout="@layout/app_bar"/>
//The rest of your layout       
</RelativeLayout>

For the Toolbar, add top margin attribute:

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="@color/primaryColor"
app:theme="@style/MyCustomToolBarTheme"
app:popupTheme="@style/ThemeOverlay.AppCompat.Dark"
android:elevation="@dimen/toolbarElevation"
android:layout_marginTop="@dimen/appBarTopMargin"
android:textDirection="ltr"
android:layoutDirection="ltr">

</android.support.v7.widget.Toolbar>

In your appTheme style-v19.xml and styles-v21.xml, add the windowTranslucent attr:

styles-v19.xml, v21:

<resources>
<item name="android:windowTranslucentStatus">true</item>
</resources>

And finally, on your dimens, dimens-v19, dimens-v21, add the values for the Toolbar topMargin, and the height of the statusBarHeight:
dimens.xml for less than KitKat:

<resources>
<dimen name="toolbarElevation">4dp</dimen>
<dimen name="appBarTopMargin">0dp</dimen>
<dimen name="statusBarHeight">0dp</dimen>
</resources>

The status bar height is always 24dp
dimens-v19.xml for KitKat and above:

<resources>
<dimen name="statusBarHeight">24dp</dimen>
<dimen name="appBarTopMargin">24dp</dimen>
</resources>

dimens-v21.xml for Lolipop, just add the elevation if needed:

<resources>
<dimen name="statusBarElevation">4dp</dimen>
</resources>

This is the result for Jellybean KitKat and Lollipop:

A Status Bar in Android is an eye-catching part of the screen, all of the notification indication, battery life, time, connection strength, and plenty of things shows here. An Android user may look at a status bar multiple times while using an Android application. It is a very essential part of the design that the color of the status bar should follow the color combination of the layout. You can look out to many android apps on your phone and can see how they changed it according to its primary colors. There can be multiple ways for changing the status bar color but we are going to tell you about the best hand-picked two methods which you can use either in Java or Kotlin.

Method 1: Creating a New Theme

You can follow this method in apps that are built with Kotlin or Java. It will work in both.

Step 1: Open Android Studio and start a new project by selecting an empty activity. Give it a name of your choice, then select your language and API level. At last click on finish.

Step 2: Find an XML file called styles.xml by navigating res/values/styles.xml. 

Step 3: Find another XML file by navigating res/values/colors.xml, and also add that color here which you want to change for the status bar. 

Step 4: Now in the style.xml file, add the below code just before the </resources> tag and change the colors of it as your choice. ColorPrimaryDark is always going to be responsible for your status bar color. 

You can do the same with android:statusBarColor but it will work only in above API Level 21. ColorPrimaryDark for the status bar will also not support in API Level 19. By default in most of the API Levels, ColorPrimaryDark will be the default color for statusBarColor, So it is good to go with changing ColorPrimaryDark. 

Tip: You can create multiple themes and you can use them in any activity. In any theme, There is a set of colors that needs to be defined, you can also create new colors in the colors.xml file in the same directory and use it on the styles.xml file.

Step 6: Now go to the manifest/AndroidManifest.xml and here search the activity for which you want to apply that theme or change the color of the status bar. and add an attribute android:theme=”@style/DemoTheme”. 

That’s done! Check your application by running it on an emulator or a physical device.

Method 2: Using setStatusBarColor Method

This method can be only used in the above API Level 21. Officially status bar color is not supporting below API Level 21. Although, Here we added an if condition, because in case if you haven’t selected above or equal to API 21 then it will check the android API Version, and then it will execute the code. It will not change the color of the status bar is below API Level 21 but the rest code will work well.

Step 1: After opening the android studio and creating a new project with an empty activity.

Step 2: Navigate to res/values/colors.xml, and add a color that you want to change for the status bar.

Step 3: In your MainActivity, add this code in your onCreate method. Don’t forget to replace your desired color with colorName. 

Step 4: Try running your application on an android emulator or a physical device. See the changes.

Output for both the methods will be the same:

Changing the Android status bar color is very easy in Android Studio. Set color on android:colorPrimaryDark the attribute of the style you’re using for your app in styles.xml.

Android 5.0 Lollipop introduced Material Design theme which automatically colors the status bar based on the colorPrimaryDark value of the theme.

Code

<color name="colorPrimaryDark">#2196F3</color>

On API level 21+ you can also use the Window.setStatusBarColor() method from code.

You can use this simple code in Kotlin:

window.statusBarColor = ContextCompat.getColor(this, R.color.colorName)

Let’s build an Android status bar color change application

Step 1. Create an android project in the android studio (Follow this tutorial: Android First Program in Android Studio).

Step 2. Open the color.xml file.

Step 3. Add your color in the color.xml file.

You can add status bar color in 2 ways, First clicking on left side color box-> it will open a color selector.

Another way direct write a color hex code.

Step 4. Now Run the application, in an emulator or on your Android device.

Q: How to change Action Bar and Status Bar color in Activity?

Answer: If you want to change the color of my action bar and status bar programmatically only on one activity. Then use this Java(for Kotlin you just copy past and chose change to Kotlin) code.

import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.os.Build;
import android.support.v4.content.ContextCompat;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        changeColor(R.color.red);
    }


    public void changeColor(int resourseColor) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            getWindow().setStatusBarColor(ContextCompat.getColor(getApplicationContext(), resourseColor));
        }

        ActionBar bar = getSupportActionBar();
        bar.setBackgroundDrawable(new ColorDrawable(getResources().getColor(resourseColor)));

    }

}

Window window = activity.getWindow();

// clear FLAG_TRANSLUCENT_STATUS flag:
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

// add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

// finally change the color
window.setStatusBarColor(activity.getResources().getColor(R.color.my_statusbar_color));

 if (Build.VERSION.SDK_INT >= 21) {
        getWindow().setNavigationBarColor(ContextCompat.getColor(this, R.color.dark_nav)); // Navigation bar the soft bottom of some phones like nexus and some Samsung note series  
        getWindow().setStatusBarColor(ContextCompat.getColor(this,R.color.statusbar)); //status bar or the time bar at the top
