我如何能在全球范围强制屏幕方向Android中？ [英] How can I globally force screen orientation in Android?

问题描述

有一个数字，是能够迫使屏幕旋转的应用程序。他们的工作，即使一个应用程序，明确要在另一个方向来看待。现在我禁用加速旋转系统设置，并设置我的preferred方向。一个应用程序仍然可以忽略这一点。

There are a number of apps that are able to force screen rotation. They work even if an app explicitly wants to be viewed in another orientation. Right now I am disabling the accelerometer rotation system setting and setting my preferred orientation. An app can still override this.

下面是能够覆盖一个应用程序的请求的方向的应用程序之一：

Here is one of the apps that is able to override an app's requested orientation:

推荐答案

这可以通过创建一个隐藏的系统对话框进行。其样的黑客攻击，但其疯狂到工作。

This can be done by creating a hidden system dialog. Its kind of a hack but its crazy enough to work.

    wm = (WindowManager) content.getSystemService(Service.WINDOW_SERVICE);

    orientationChanger = new LinearLayout(content);
    orientationChanger.setClickable(false);
    orientationChanger.setFocusable(false);
    orientationChanger.setFocusableInTouchMode(false);
    orientationChanger.setLongClickable(false);

    orientationLayout = new WindowManager.LayoutParams(
            LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT,
            windowType, WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
                    | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
            PixelFormat.RGBA_8888);

    wm.addView(orientationChanger, orientationLayout);
    orientationChanger.setVisibility(View.GONE);

    orientationLayout.screenOrientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
    wm.updateViewLayout(orientationChanger, orientationLayout);
    orientationChanger.setVisibility(View.VISIBLE);
