接收触摸事件从一个服务（解决方案？） [英] Receiving Touch Events from a Service (Solution?)

问题描述

所以，我早些时候发布了有关问题，从服务接收触摸事件（显然没有人知道答案）。

So, earlier I posted a question about receiving touch events from a service (apparently no one knows the answer).

在试图找出自己好几个小时，我放弃了，决定到电子邮件被称为RubberBigPepper开发。我问他是怎么做到的在他的应用程序的音量控制，他立即回答 TYPE_SYSTEM_ALERT窗口

After trying to figure it out myself for hours, I gave up and decided to email a developer known as RubberBigPepper. I asked him how he did it in his app Volume control and he promptly responded "TYPE_SYSTEM_ALERT window".

这是什么意思，以及它如何在code来实现？

What does this mean, and how can it be implemented in code?

编辑：

我用下面的方法：

getWindow().addFlags(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);

和窗口未能接收触摸事件。

and the window failed to receive touch events.

我给他有关这个问题，以及，他说：使用WindowService添加你的窗口

I emailed him about this as well and he says: "Use the WindowService to add your window"

推荐答案

我用code这样的。

int nFlags=WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL|WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;       
             m_cWM=(WindowManager)getSystemService(Context.WINDOW_SERVICE);
             WindowManager.LayoutParams lp = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
                nFlags,
                PixelFormat.TRANSLUCENT);
m_cWM.addView(YourViewClass, lp);

和不要忘了使用，权限
