虚拟导航栏只有黑色，能不能调成半透明或是多加一个隐藏摁键？

Transparency is achievable,

Window window = getWindow();
    // 状态栏透明
    window.setFlags(
        WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
        WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    // 虚拟导航栏透明
    window.setFlags(
        WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION,
        WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);

You need to check the version, which is only available after 4.4.
The corresponding activity layout needs to add the following attribute to the layout root node.

android:fitsSystemWindows="true"

getWindow().setStatusBarColor() can set the color of the top status bar

If you want the layout to extend to the navigation bar or status bar, refer to the 1L settings

The bottom navigation bar is designed to add buttons...
