Need fully transparent status bar

问题:

Hi Friends I want to know can I change status bar color or make it completely transparent.

I've tried so many things but I can't get the fully transparent status bar, so here is my code..

v21/style.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

        style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
            <!-- Customize your theme here. -->
            <item name="colorPrimary">@color/colorPrimary</item>
            <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
            <item name="colorAccent">@color/colorAccent</item>

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

            <item name="android:windowNoTitle">true</item>
            <item name="android:statusBarColor">@android:color/transparent</item>
            <item name="android:windowTranslucentNavigation">true</item>
        </style>
</resources>

and style.xml

    <resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->

// transparent statusbar for marshmallow and above
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (yourView != null) {
            yourView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
        }
    }

    //make full transparent statusBar
    if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
        setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true);
    }
    if (Build.VERSION.SDK_INT >= 19) {
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
    }
    if (Build.VERSION.SDK_INT >= 21) {
        setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false);
        getWindow().setStatusBarColor(Color.TRANSPARENT);
    }

 public static void setWindowFlag(Activity activity, final int bits, boolean on) {
    Window win = activity.getWindow();
    WindowManager.LayoutParams winParams = win.getAttributes();
    if (on) {
        winParams.flags |= bits;
    } else {
        winParams.flags &= ~bits;
    }
    win.setAttributes(winParams);
}

You don't need to write all these stuff, just add in your kotlin activity

requestWindowFeature(Window.FEATURE_NO_TITLE)
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN)

and in your theme

<item name="android:windowActivityTransitions">true</item>
