安卓开发——系统UI

Question

现在安卓主流的屏下摄像头，或者水滴屏的手机

为什么设置了全屏之后状态栏就变黑了，

怎么样才能设置成沉浸式的全屏模式呢

Answer 1

隐藏insets

private void hideStatusBar() {
    WindowInsetsController windowInsetsController = getWindow().getDecorView().getWindowInsetsController();
    assert windowInsetsController != null;
    windowInsetsController.hide(WindowInsets.Type.statusBars());
}
