if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    Window window = getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
                        /*| WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION*/);
                window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        /*| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION*/
                        | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
                window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
                window.setStatusBarColor(Color.TRANSPARENT);
//                window.setNavigationBarColor(Color.TRANSPARENT);
                LinearLayout linear_bar = (LinearLayout) findViewById(R.id.status_bar_ll);
                linear_bar.setVisibility(View.VISIBLE);
                //获取到状态栏的高度
                int statusHeight = SystemUtil.getStatusBarHeight(this);
                //动态的设置隐藏布局的高度
                LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) linear_bar.getLayoutParams();
                params.height = statusHeight;
                linear_bar.setLayoutParams(params);
            }

/**
     * 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;
    }

其中：linear_bar 为布局里面标题栏上面1dp大小占位

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/base_layout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">

    <LinearLayout
        android:id="@+id/status_bar_ll"
        android:layout_width="fill_parent"
        android:layout_height="1dp"
        android:background="@color/main_theme_color"
        android:orientation="vertical"
        android:visibility="gone"/>

    <LinearLayout
        android:id="@+id/layout_head"
        android:layout_width="match_parent"
        android:layout_height="48dip"
        android:background="@color/main_theme_color"
        android:orientation="horizontal">
     ...

以上就实现了Android 沉浸式状态栏。

但如果你Activity底部有输入框，需要弹出键盘，上述方式会导致布局不受挤压键盘，直接遮挡住输入框，解决方案很简单，即在布局文件最开头加入：

android:fitsSystemWindows="true"
