我有应用程序，我使用OverlayService绘制“allways-on-top”图标。当我点击这个图标时，我想显示对话框（自定义视图）。问题是，当应用程序暂停时 - 当我点击图标时没有任何反应，因为应用程序没有响应事件，暂停时。你可以帮帮我吗？谢谢。

答案 0 :(得分：0)
您也可以使用BroadcastReceiver并确保注册它！ 然后，如果您使用对话框将以下代码复制到对话框代码中。
yourDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
将权限添加到 manifest.xml
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
不要忘记实现代码来检查android 6.0.1的权限。
