沉浸式分为两类：

1.在根布局使用属性android:fitsSystemWindows="true"（布局不会沉到状态栏中）
这种情况需要给根布局设置背景图

2.在根布局不使用属性android:fitsSystemWindows="true"（布局会沉到状态栏中）
这种情况不需要给根布局设置背景图。

   这两种1.2情况只需这样做就行了。
   在onCreate()方法的setContentView()之后设置代码：
   SystemBarUtils.setStatusBar(this, false, true);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}

-----------------------------------------------------------------------------------------------------------------------------------------------------------

3.去除状态栏。（闪屏页都会去掉状态栏）
在setContentView()方法前面调用方法：
/**
* 去除状态栏
*/
private void setPreviewImgTitleSetting() {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
// 透明状态栏
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
// 透明导航栏
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}

4.在当前页面的布局上边添加TitleBar
在子类中的setContentView 方法中调用 TitleBarUtil.setDefaultFloatBar()可以参考。

public class SystemBarUtils {
    public static int screenWidth;
    public static int screenHeight;
    public static int navigationHeight = 0;

    private static DisplayMetrics mMetrics;
    public static final String HOME_CURRENT_TAB_POSITION = "HOME_CURRENT_TAB_POSITION";

    /**
     * 通过反射的方式获取状态栏高度
     *
     * @return
     */
    public static int getStatusBarHeight(Context context) {
        try {
            Class<?> c = Class.forName("com.android.internal.R$dimen");
            Object obj = c.newInstance();
            Field field = c.getField("status_bar_height");
            int x = Integer.parseInt(field.get(obj).toString());
            return context.getResources().getDimensionPixelSize(x);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return 0;
    }

    /**
     * 获取底部导航栏高度
     *
     * @return
     */
    public static int getNavigationBarHeight(Context context) {
        Resources resources = context.getResources();
        int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
        //获取NavigationBar的高度
        navigationHeight = resources.getDimensionPixelSize(resourceId);
        return navigationHeight;
    }

    //获取是否存在NavigationBar
    public static boolean checkDeviceHasNavigationBar(Context context) {
        boolean hasNavigationBar = false;
        Resources rs = context.getResources();
        int id = rs.getIdentifier("config_showNavigationBar", "bool", "android");
        if (id > 0) {
            hasNavigationBar = rs.getBoolean(id);
        }
        try {
            Class systemPropertiesClass = Class.forName("android.os.SystemProperties");
            Method m = systemPropertiesClass.getMethod("get", String.class);
            String navBarOverride = (String) m.invoke(systemPropertiesClass, "qemu.hw.mainkeys");
            if ("1".equals(navBarOverride)) {
                hasNavigationBar = false;
            } else if ("0".equals(navBarOverride)) {
                hasNavigationBar = true;
            }
        } catch (Exception e) {

        }
        return hasNavigationBar;

    }

    /**
     * @param activity
