Change status / notification bar color on api below 21 android?

问题

I have seen in some apps the status bar color could be changed and matched to as what is being done in api level 21.

I searched and found this solution Source

<style name="Theme.MyTheme" parent="Theme.AppCompat.Light">   
<!-- Set AppCompat’s color theming attrs -->
<item name="colorPrimary">@color/my_awesome_red</item>
<item name="colorPrimaryDark">@color/my_awesome_darker_red</item>
<!-- Other attributes -->
</style>

But it is not working

This is my style code

<style name="ToolbarTheme" parent="Theme.AppCompat">
    <item name="android:windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="colorPrimary">@color/ColorPrimary</item>
    <item name="colorPrimaryDark">@color/ColorPrimaryDark</item>
</style>

If you mean the color of AcionBar, you can change programmatically the color with this code:

getSupportActionBar().setBackgroundDrawable(new Color.Drawable(Color.rgb(120,0,47)));

Change numbers to select your own color.

StatusBar is only for devices with API level more than 21. If your min API level is less than that then you have to do some change in your java source file. Go to the source file to which you want to add the status bar color. Then wrap the OnCreate() method with annotation @TargetApi(Build.VERSION_CODES.LOLLIPOP).

Then inside the method you have to check whether the device is capable or not as shown below.

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
 window.setStatusBarColor(getResources().getColor(R.color.Statusbar));
    }

Hope it works..!!
