Question

我需要你的帮助，我们目前正在使用worklight混合应用程序并使用sencha框架，我们需要在用户按下android后退按钮时触发。实际上，在我需要关闭应用程序之后，我试图从我的设备获得警报。我们目前收到警告YES或NO确认消息显示在设备上。如果我单击是表示我想要关闭或最小化应用程序。在我试过的代码下面。如何使用worklight API关闭应用程序？

        <asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional" >
            <ContentTemplate>
                <asp:Table class="mel-table" style="text-align: center" runat="server" id="mytab1">
                    <asp:TableRow>
                        <asp:TableCell>Case Number :</asp:TableCell>
                        <asp:TableCell>
                            <asp:TextBox ID="caseNumber" runat="server"></asp:TextBox>
                        </asp:TableCell>
                    </asp:TableRow>
                </asp:Table>
                <asp:Button OnClick="btnOK1_Click" ID="btnOK1" runat="server" Text="Save" />
            </ContentTemplate>
        </asp:UpdatePanel>

在Android和iOS中，不再考虑退出应用程序，应该以编程方式执行此操作。这是一个必须由最终用户明确完成的动作。

意思是，在应用程序“关闭”后，最终用户必须使用打开应用程序列表的物理/软件按钮，并通过从列表中滑动应用程序退出应用程序。

这有效：

function wlCommonInit(){
    WL.App.overrideBackButton(checkQuit());
}

function checkQuit() {
    WL.SimpleDialog.show(
            "Quit application", 
            "Are you sure?", 
            [
             {text: "Yes", handler: function() {WL.App.close();}},
             {text: "No", handler: function() {}}
             ]
    );
}
