android - 尽管出现了弹出窗口、覆盖层或对话框，但如何隐藏导航栏？

Question

我正在尝试创建一个在特定时间启动的全屏应用程序，当它启动时，它应该自动变为全屏。我在全屏启动它时没有任何问题。但是，如果存在弹出窗口或窗口，然后启动我的 Activity ，则导航栏永远不会隐藏(换句话说，无法实现全屏状态)。我制作了一个 5 秒的视频来演示这个问题。

我已经尝试了所有带有标志的方法，但似乎无法完成。我环视了 Playstore，似乎许多锁屏应用程序尤其可以轻松隐藏导航栏，尽管存在任何弹出窗口\其他对话框(SlideLock、Echo Lock Screen)。

下面是我的简单 Activity 代码:

list 中:<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

windowlayout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#a9e487">

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Exit"
    android:id="@+id/button"
    android:layout_gravity="center"
    android:layout_marginTop="100dp" />
</LinearLayout>

MainActivity.java

public class MainActivity extends AppCompatActivity {

    final static WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
            WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS |
            WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION |
            WindowManager.LayoutParams.FLAG_FULLSCREEN |
            WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS |
            WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN, //Covers status bar
            PixelFormat.TRANSPARENT);

    final static int flags = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_FULLSCREEN
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.content_main);

        final View decorView = getWindow().getDecorView();
        decorView.setSystemUiVisibility(flags);

        final ViewGroup viewGroup = (ViewGroup) getLayoutInflater().inflate(R.layout.windowlayout, null);
        final WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
        windowManager.addView(viewGroup, params);

        viewGroup.findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                windowManager.removeView(viewGroup);
            }
        });

    }

}

This worked for me:

  mypopupWindow = PopupWindow(
                    view,
                    RelativeLayout.LayoutParams.MATCH_PARENT,
                    RelativeLayout.LayoutParams.MATCH_PARENT,
                    false
            )

或者

mypopupWindow.isFocusable = false
