SystemAlertDialogManager 类

public class SystemAlertDialogManager : Activity    {        private Dialog mDialog;        private Button mYes;        private Button mNo;        private Context mContext;        private TextView tvTitle;        public SystemAlertDialogManager(Context context)        {            this.mContext = context;        }        public void ShowRecordingDialog(string remind, string yes, string no)        {            this.mDialog = new Dialog(mContext, Resource.Style.SystemAlertDialog);            this.mDialog.RequestWindowFeature((int)WindowFeatures.NoTitle);            LayoutInflater inflate = LayoutInflater.From(mContext);            View view = inflate.Inflate(Resource.Layout.dialog_confirm, null);            mDialog.SetContentView(view);            this.mYes = view.FindViewById<Button>(Resource.Id.btnSure);            this.mNo = view.FindViewById<Button>(Resource.Id.btnCancel);            this.tvTitle = view.FindViewById<TextView>(Resource.Id.tvTitle);            tvTitle.Text = remind;            mYes.Text = yes;            mNo.Text = no;            mYes.Click += mYes_Click;            mNo.Click += mNo_Click;            mDialog.Show();        }        void mNo_Click(object sender, EventArgs e)        {            if (NoClicked != null)            {                NoClicked(mContext, e);            }        }        void mYes_Click(object sender, EventArgs e)        {            if (YesClicked != null)            {                YesClicked(mContext, e);            }        }        public void CloseDialog()        {            this.mDialog.Dismiss();            this.mDialog.Dispose();            this.mDialog = null;        }        public event EventHandler<EventArgs> YesClicked;        public event EventHandler<EventArgs> NoClicked;    }

界面中使用

var msg = new SystemAlertDialogManager(this);            msg.ShowRecordingDialog("是否删除数据", "确定", "取消");            msg.YesClicked += new EventHandler<EventArgs>((a, b) =>            {                msg.CloseDialog();                //这里点击确定以后要执行的操作            });            msg.NoClicked += new EventHandler<EventArgs>((a, b) =>            {                msg.CloseDialog();            });
