根据我对问题的理解,您希望获得一个表单xml文件视图,并将其添加到窗口中
您可以使用
View-View=LayoutInflater.from(context).充气(r.layout.overlay,null,false)编码>并使用窗口管理器将视图添加到窗口中。添加视图(视图)
。单击按钮时发送广播,并从广播接收器onReceive方法启动活动。
创建广播接收器,然后在服务的创建()上注册广播接收器。单击按钮时广播意图。最后,单击覆盖按钮时,接收器将打开一个活动(布局)
如果你只想打开一个对话框,这是一个不错的答案
事实证明,你也可以像这里提到的那样,将一个活动主题化为一个对话框
单击“在覆盖上发送广播”按钮
注册广播接收器onCreate()
取消注册广播接收器onDestroy()
只需使用view创建另一个服务并在单击时显示它onClick
是什么阻止您膨胀该布局并通过WindowManager#addView()
添加它,就像您为该按钮所做的那样?比如:wm.addView(MY#view,params)?但我想设置一个类似于R.Layout.overlay的布局。如何将其转换为视图?@Jéwôm'请定义您将在弹出窗口中执行的操作?如果需要任何帮助,请发表评论,我已经测试了它,它正在工作。
