Android状态栏颜色修改

随笔

修改状态栏背景色

1.添加调用方法（Activity , color）;

initStatusBar(this, R.color.black);

方法拆分_1

public void initStatusBar(Activity activity, @ColorRes int backgroundColor) {
    setWindowImmersive();
    ViewGroup root = (ViewGroup) ((ViewGroup) activity.findViewById(android.R.id.content)).getChildAt(0);
    View layoutView = null;
    boolean isContainLinearLayout = false;
    if (root instanceof LinearLayout) {
        layoutView = root;
        isContainLinearLayout = true;
    } else {
        int childCount = root.getChildCount();
        for (int i = 0; i < childCount; i++) {
            layoutView = root.getChildAt(i);
            if (layoutView instanceof LinearLayout) {
                isContainLinearLayout = true;
                break;
            }
        }
    }

    if (isContainLinearLayout && ((LinearLayout) layoutView).getOrientation() == LinearLayout.VERTICAL) {
        if ((((LinearLayout) layoutView).findViewById(R.id.header_statu_bar)) != null) {
            View statu_bar = ((LinearLayout) layoutView).findViewById(R.id.header_statu_bar);
            statu_bar.setBackgroundColor(getResources().getColor(backgroundColor));
            return;
        }
        View status_bar = new View(activity);
        status_bar.setBackgroundColor(getResources().getColor(backgroundColor));
        status_bar.setId(R.id.header_statu_bar);
        LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        lp.height = StatusBarUtil.getStatusBarHeight(this);
        status_bar.setLayoutParams(lp);

        if (Build.VERSION.SDK_INT >= 19) {
            ((LinearLayout) layoutView).addView(status_bar, 0);
        }
    }
}

方法拆分_2

protected void setWindowImmersive() {
    StatusBarUtil.setWindowImmersive(getWindow());
    setNavigationBar(StatusBarUtil.isLightOrDark(ResourcesCompat.getColor(getResources(), R.color.Primary_Background, null)));
    StatusBarUtil.changeStatusBarTextColor(getColor(), this);
}

public static void setWindowImmersive(Window window) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
        );
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            window.setStatusBarColor(Color.TRANSPARENT);
        }

    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    }
}

public void setNavigationBar(boolean islight) {
    int systemUiVisibility = getWindow().getDecorView().getSystemUiVisibility();
    int bgcolor = android.R.color.black;
    if (islight) {
        bgcolor = android.R.color.white;
        systemUiVisibility |= View.SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR;
    } else {
        systemUiVisibility &= ~View.SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR;
    }
    getWindow().setNavigationBarColor(ResourcesCompat.getColor(getResources(), bgcolor, null));
    getWindow().getDecorView().setSystemUiVisibility(systemUiVisibility);
}

@Override
public Resources getResources() {

    Resources res = super.getResources();
    if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.N) {
        Configuration config = res.getConfiguration();
        //跟随系统
        config.fontScale = FontScaleUtil.getFontScale(this);
        res.updateConfiguration(config, res.getDisplayMetrics());
    }
    return res;
}

public static boolean isLightOrDark(int color) {
    boolean flag = false;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
        flag = Color.luminance(color) > 0.5;
    } else {
        flag = isLightColor(color);
    }
    return flag;
}

public static boolean isLightColor(int color) {
    double darkness = 1 - (0.299 * Color.red(color) + 0.587 * Color.green(color) + 0.114 * Color.blue(color)) / 255;
    if (darkness < 0.5) {
        return true; // It's a light color
    } else {
        return false; // It's a dark color
    }
}

方法拆分_3

public static void changeStatusBarTextColor(int color,Activity activity) {
       if (isLightOrDark(color)) {
           setLightStatusBar(activity); //黑色
       } else {
           clearLightStatusBar(activity); //白色
       }

}

    public static void setLightStatusBar(Activity activity) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            int flags = activity.getWindow().getDecorView().getSystemUiVisibility(); // get current flag
            flags |= View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR;   // add LIGHT_STATUS_BAR to flag
            activity.getWindow().getDecorView().setSystemUiVisibility(flags);
        }else  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP&&Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
//            activity.getWindow().getDecorView().setSystemUiVisibility(
//                    View.SYSTEM_UI_FLAG_LAYOUT_STABLE
//                            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
//
//            activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            activity.getWindow().setStatusBarColor(activity.getResources().getColor(R.color.Primary_Navigation_Bar_Background));
        }else{
            Logger.e(TAG,"current system api level is"+Build.VERSION.SDK_INT);
        }
    }

    public static void clearLightStatusBar(Activity activity) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            int flags = activity.getWindow().getDecorView().getSystemUiVisibility(); // get current flag
            flags &= ~View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR;
            activity.getWindow().getDecorView().setSystemUiVisibility(flags);
        }else  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP&&Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
//            activity.getWindow().getDecorView().setSystemUiVisibility(
//                    View.SYSTEM_UI_FLAG_LAYOUT_STABLE
//                            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
//
//            activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            activity.getWindow().setStatusBarColor(activity.getResources().getColor(R.color.lxsk_grey3));
        }else{
            Logger.e(TAG,"current system api level is"+Build.VERSION.SDK_INT);
        }
    }

ids.xml  避免状态栏重复添加
<item name="header_statu_bar" type="id"/>

public static int getStatusBarHeight(Context context) {
    if (context == null) {
        context = BContext.context();
    }
    return getInternalDimensionSize(context, STATUS_BAR_HEIGHT_RES_NAME);
}

private static int getInternalDimensionSize(Context context, String key) {
    if (context == null) {
        Logger.e(TAG, "%s", "getInternalDimensionSize return -1 key=" + key + " context=null");
        return -1;
    }
    Resources resources = context.getResources();
    int result = -1;
    int resourceId = resources.getIdentifier(key, "dimen", "android");
    if (resourceId > 0) {
        result = resources.getDimensionPixelSize(resourceId);
    }
    return result;
}

2.移除调用方法

public void removeStatusBar(Activity activity) {
    if (status_bar == null) {
        return;
    }
    ViewGroup root = (ViewGroup) ((ViewGroup) activity.findViewById(android.R.id.content)).getChildAt(0);
    View layoutView = null;
    boolean isContainLinearLayout = false;
    if (root instanceof LinearLayout) {
        layoutView = root;
        isContainLinearLayout = true;
    } else {
        int childCount = root.getChildCount();
        for (int i = 0; i < childCount; i++) {
            layoutView = root.getChildAt(i);
            if (layoutView instanceof LinearLayout) {
                isContainLinearLayout = true;
                break;
            }
        }
    }

    if (isContainLinearLayout && ((LinearLayout) layoutView).getOrientation() == LinearLayout.VERTICAL) {
        if (Build.VERSION.SDK_INT >= 19) {
            ((LinearLayout) layoutView).removeView(status_bar);
        }
    }
}

3.修改状态栏的图标颜色

public static void changeStatusBarTextColor(int color,Activity activity) {
       if (isLightOrDark(color)) {
           setLightStatusBar(activity); //黑色
       } else {
           clearLightStatusBar(activity); //白色
       }

}
