悬浮窗应该怎么设置，特别是flag

悬浮窗应该怎么设置，特别是flag
才能使自定义的view能够拖动的同时，也能够在EditView中输入内容，还能防止backpress失效

```java
FLAG_TRANSLUCENT_STATUS这个要怎么用

public class Floating_Service extends Service {
    public static boolean isStarted = false;

    private WindowManager windowManager;
    private WindowManager.LayoutParams layoutParams;

    private View displayView;

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        isStarted = true;
        windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
        layoutParams = new WindowManager.LayoutParams();//O=26
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            layoutParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
        } else {
            layoutParams.type = WindowManager.LayoutParams.TYPE_PHONE;
        }
        layoutParams.format = PixelFormat.RGBA_8888;

                WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS|

        layoutParams.height = 500;
        layoutParams.x = 300;
        layoutParams.y = 300;
    }

    private void showFloatingWindow() {

                case MotionEvent.ACTION_DOWN:
                    x = (int) event.getRawX();
                    y = (int) event.getRawY();
                    break;

                    int movedY = nowY - y;
                    x = nowX;
                    y = nowY;
                    layoutParams.x = layoutParams.x + movedX;

                    windowManager.updateViewLayout(view, layoutParams);
                    break;
                default:

            }
