Status Bar Customization Approaches

Android provides different methods for status bar customizatino across versions:

• Android 4.4-5.0: Requires creating a transparent status bar with a colored view overlay
• Android 5.0-6.0: Introduces setStatusBarColor() but lacks native text color control
• Android 6.0+: Supports both status bar color and text/icon color modification

Implementation Details

Basic Setup

First, modify the app theme to remove the default action bar:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
</style>

Create a utility class to handle status bar operations:

public class StatusBarHelper {
    public static int getStatusBarHeight(Context ctx) {
        int height = 0;
        try {
            int resId = ctx.getResources().getIdentifier("status_bar_height", "dimen", "android");
            if (resId > 0) height = ctx.getResources().getDimensionPixelSize(resId);
        } catch (Exception e) { /* Handle exception */ }
        return height;
    }
}

Android 5.0+ Implementation

public static void applyStatusBarColor(Window window, int color) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
        window.setStatusBarColor(color);
        adjustTextColor(window, color);
    }
}

private static void adjustTextColor(Window window, int backgroundColor) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        View decor = window.getDecorView();
        int flags = decor.getSystemUiVisibility();
        boolean darkText = ColorUtils.calculateLuminance(backgroundColor) > 0.5;
        decor.setSystemUiVisibility(darkText ? 
            flags | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR : 
            flags & ~View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
    }
}

Android 4.4 Implmeentation

@RequiresApi(api = Build.VERSION_CODES.KITKAT)
public static void applyLegacyStatusBar(Window window, int color) {
    window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    ViewGroup decor = (ViewGroup) window.getDecorView();
    View content = decor.findViewById(android.R.id.content);
    if (content != null) content.setPadding(0, getStatusBarHeight(window.getContext()), 0, 0);
    
    View statusBarView = new View(window.getContext());
    FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(
        ViewGroup.LayoutParams.MATCH_PARENT, 
        getStatusBarHeight(window.getContext()));
    statusBarView.setLayoutParams(params);
    statusBarView.setBackgroundColor(ColorUtils.blendARGB(Color.BLACK, color, 0.5f));
    decor.addView(statusBarView);
}

Notch Display Adaptation

For full-screen activities like splash screens:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
    WindowManager.LayoutParams params = getWindow().getAttributes();
    params.layoutInDisplayCutoutMode = 
        WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES;
    getWindow().setAttributes(params);
}

Add manufacturer-specific adaptations in AndroidManifest.xml:

<meta-data android:name="notch.config" android:value="portrait" />
<meta-data android:name="android.notch_support" android:value="true" />
<meta-data android:name="android.max_aspect" android:value="2.2" />
