Android 状态栏颜色

状态栏颜色的修改在4.4和5.x环境下分别有不同的方式,低于4.4以下是不能修改的。

1、状态栏修改是用到的一些字段，一张图解决！

2、状态栏颜色设置主要有三次变化

1、android 4.4 API 19 首次支持状态栏颜色的修改
2、android 5.0 API 21 添加了可以直接设置状态栏颜色的属性：
window.setStatusBarColor(Color.TRANSPARENT);
3、android 6.0 API 23 支持浅色状态栏模。

3、代码

        //API 版本大于23时，安卓6.0以上 状态栏颜色
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {//API level 最小为23,
            window.getDecorView()
                  .setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
            window.setStatusBarColor(Color.TRANSPARENT);
        }

        //安卓 API版本大于 21 安卓5.0以上 状态栏颜色
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP && Build.VERSION.SDK_INT<Build.VERSION_CODES.M){
            window.addFlags(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);
            window.setStatusBarColor(Color.TRANSPARENT);

            ViewGroup mContentView = findViewById(Window.ID_ANDROID_CONTENT);
            View mChildView = mContentView.getChildAt(0);
            if (mChildView != null){
                ViewCompat.setFitsSystemWindows(mChildView,true);//是否为系统 View 预留出空间, 当设置为 true 时,会预留出状态栏的空间
            }

        }
        //安卓 API版本大于 19 安卓 4.4以上 状态栏颜色修改支持的最低版本
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && Build.VERSION.SDK_INT <Build.VERSION_CODES.LOLLIPOP){
            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            ViewGroup mContentView = findViewById(Window.ID_ANDROID_CONTENT);
            View statusBarView = mContentView.getChildAt(0);
            int statusBarHeight = getStatusBarHeight(this);
            if (statusBarView != null && statusBarView.getLayoutParams()!=null&& statusBarView.getLayoutParams().height == statusBarHeight){
                //避免添加重复View
                statusBarView.setBackgroundColor(Color.RED);
                return;
            }
            if (statusBarView != null){
                ViewCompat.setFitsSystemWindows(statusBarView,true);
            }
            statusBarView = new View(this);
            ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,statusBarHeight);
            statusBarView.setBackgroundColor(Color.RED);
            mContentView.addView(statusBarView,0,lp);
        }

private static int getStatusBarHeight(Context context) {
        int statusBarHeight = 0;
        Resources res = context.getResources();
        int resourceId = res.getIdentifier("status_bar_height", "dimen", "android");
        if (resourceId > 0) {
            statusBarHeight = res.getDimensionPixelSize(resourceId);
        }
        return statusBarHeight;
    }

小米和魅族底层已经兼顾到状态栏了，而且公开了源码，赞！

public static boolean FlymeSetStatusBarLightMode(Window window, boolean dark) {
        boolean result = false;
        if (window != null) {
            try {
                WindowManager.LayoutParams lp = window.getAttributes();
                Field darkFlag = WindowManager.LayoutParams.class
                        .getDeclaredField("MEIZU_FLAG_DARK_STATUS_BAR_ICON");
                Field meizuFlags = WindowManager.LayoutParams.class
                        .getDeclaredField("meizuFlags");
                darkFlag.setAccessible(true);
                meizuFlags.setAccessible(true);
                int bit = darkFlag.getInt(null);
                int value = meizuFlags.getInt(lp);
                if (dark) {
                    value |= bit;
                } else {
                    value &= ~bit;
                }
                meizuFlags.setInt(lp, value);
                window.setAttributes(lp);
                result = true;
            } catch (Exception e) {

            }
        }
        return result;
    }

public static boolean MIUISetStatusBarLightMode(Window window, boolean dark) {
        boolean result = false;
        if (window != null) {
            Class clazz = window.getClass();
            try {
                int darkModeFlag = 0;
                Class layoutParams = Class.forName("android.view.MiuiWindowManager$LayoutParams");
                Field field = layoutParams.getField("EXTRA_FLAG_STATUS_BAR_DARK_MODE");
                darkModeFlag = field.getInt(layoutParams);
                Method extraFlagField = clazz.getMethod("setExtraFlags", int.class, int.class);
                if (dark) {
                    extraFlagField.invoke(window, darkModeFlag, darkModeFlag);//状态栏透明且黑色字体
                } else {
                    extraFlagField.invoke(window, 0, darkModeFlag);//清除黑色字体
                }
                result = true;
            } catch (Exception e) {

            }
        }
        return result;
    }

设置自布局不会占据状态栏的位置

android:fitsSystemWindows="true"
android:clipToPadding="true"
