如何创建的Andr​​oid系统的覆盖，让与它下面的窗口互动？ [英] How to create a system overlay in Android which allows interaction with the windows below it?

问题描述

在本应用所看到的，我想创建一个通过创建一个阴影覆盖变暗屏幕的应用程序。

As seen in this app, I want to create an app which dims the screen by creating a shaded overlay.

创建的窗口，它是部分透明的，但是，我不能得到它下面的应用程序启动。我可以点击他们，看到按钮presses，但我正在运行时，其他应用程序无法启动。

The window is created, and it's partially transparent, however, I cannot get the applications below it to launch. I can click them, and see the button presses, but other apps cannot launch while mine is running.

建议？

我附上我的code以下，和一个应用程序，它已经在这样做的一个例子。

I enclosed my code below, and an example of an app which is already doing this.

final WindowManager.LayoutParams params = new WindowManager.LayoutParams( 
    WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
    WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN |
    WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE | 
    WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | 
    WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
    WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
    PixelFormat.TRANSLUCENT);   

    WindowManager wm = (WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE);    

    LayoutInflater inflater = (LayoutInflater)   getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    ViewGroup mTopView = (ViewGroup) inflater.inflate(R.layout.activity_black, null);
    getWindow().setAttributes(params);
    wm.addView(mTopView, params);

推荐答案

这是简单的方式：

对话对话框=新的对话框（这一点，android.R.style.Theme_DeviceDefault_Dialog_NoActionBar_MinWidth）;
          。dialog.getWindow（）的setType（WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY）;
          。dialog.getWindow（）和setFormat（PixelFormat.TRANSLUCENT）;
          dialog.getWindow（）setDimAmount（0）。
          dialog.setContentView（新的EditText（本））;
          dialog.show（）;
