TYPE_SYSTEM_ALERT和TYPE_SYSTEM_OVERLAY之间的切换，并捕获触摸事件不能正常工作 [英] Switching between TYPE_SYSTEM_ALERT AND TYPE_SYSTEM_OVERLAY , and capturing the touch events not working properly

问题描述

我做的服务视图，它总是在Android的每个应用程序之上运行。

I made a View in service which runs always on top of every application in android.

首先，服务的行为是TYPE_SYSTEM_ALERT。

Initially, the behaviour of service is TYPE_SYSTEM_ALERT .

WindowManager.LayoutParams layparams = new WindowManager.LayoutParams(
 WindowManager.LayoutParams.WRAP_CONTENT,WindowManager.LayoutParams.WRAP_CONTENT, 
 WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
 WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
 PixelFormat.TRANSLUCENT);
 layparams .gravity = Gravity.CENTER_VERTICAL| Gravity.CENTER_HORIZONTAL;
 wm = (WindowManager) getSystemService(WINDOW_SERVICE);
 wm.addView(serviceView, layparams );

我改变服务在运行时的行为意味着触摸TYPE_SYSTEM_ALERT和TYPE_SYSTEM_OVERLAY之间的切换。切换发生时，我接触到视图参数之外，当触摸里面的视图参数。

I am changing the behaviour of service at run time means switching between TYPE_SYSTEM_ALERT AND TYPE_SYSTEM_OVERLAY on touch. Switch take place when I touch outside the view parameters and when touch inside the view parameters.

layparams .type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;
Using updateViewLayout(serviceView, layparams )

问题：是，当我接触来看之外，第一触摸刚刚启动TYPE_SYSTEM_OVERLAY之后再以外的应用程序工作正常。当TYPE_SYSTEM_OVERLAY正在工作，之后，如果将视图内触摸它会触发对象的视图不视图的动作后面的动作。但是，当u一旦触碰观点TYPE_SYSTEM_ALERT将被应用到现在的视图将正常。

PROBLEM: Is when I touch outside of view , the first touch just activate TYPE_SYSTEM_OVERLAY and after then outside app works fine. When TYPE_SYSTEM_OVERLAY is working , after that when you touch within the view it will trigger the action of object behind the view not the action of the view. But when u once touch the view TYPE_SYSTEM_ALERT will be applied and now the View will behave normally .

当前实施：我要摸两次，工作是特别的事情，当开关带布局参数之间发生

Current Implementation : I have to touch twice to work that particular thing when switch take place between layout parameters.

推荐答案

使用这样的产品......完美的作品在ICS及以上

use this one... works perfectly on ICS and above

params.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;//This one is necessary.
params.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH |
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS;
params.gravity = Gravity.TOP | Gravity.RIGHT;
params.x = 0;
params.y = -params.height;
windowManager.addView(tile, params);
