android - 如何在 Android R 中设置全屏？

Question

我需要在我的应用程序中全屏显示屏幕。为此，我正在使用以下代码:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    requestWindowFeature(Window.FEATURE_NO_TITLE)
    window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN)
    setContentView(R.layout.activity_camera_photo)

但是， WindowManager.LayoutParams.FLAG_FULLSCREEN标志已弃用。
我的应用支持 Android Lollipop (API 21) 到 Android R (API 30)。
使屏幕全屏显示的正确方法是什么？

Kotlin

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.layout_container)
    @Suppress("DEPRECATION")
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        window.insetsController?.hide(WindowInsets.Type.statusBars())
    } else {
        window.setFlags(
            WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN
        )
    }
}

如果这没有帮助，请尝试删除 android:fitsSystemWindows="true"在布局文件中
JAVA

class Activity extends AppCompatActivity {

@Override
@SuppressWarnings("DEPRECATION")
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_container);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        final WindowInsetsController insetsController = getWindow().getInsetsController();
        if (insetsController != null) {
            insetsController.hide(WindowInsets.Type.statusBars());
        }
    } else {
        getWindow().setFlags(
                WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN
        );
    }
}
}
