Xamarin 小试牛刀 通知栏消息通知和按钮(基于Java代码人肉转换)
本示例基于网友现有安卓项目人肉翻译,在Xamarin中替换和修改了很多方法的命名,比如某些属性需要去掉getName的get前缀, 有些方法名称需要使用Pascal命名法替换Java的Camel 命名规范
另外在内部类的使用方式上也有一些区别,但是整体上来说,大部分的方法名称都与Java 原版Android一致,所以如果有现有的Android 项目需要转换到Xamarin 还是很容易的.此处给Xamarin 66个赞
参考Java版本:http://blog.csdn.net/wxdjaqgs/article/details/44561101
博主提供了源码下载
我所做的只是将需要的图片文件贴过来.然后开始翻译代码
由于IOS品台的打包流程还没有去研究,所以本次试验没有使用ios 测试.以后有时间补上
PS:全篇无注释(别问我,打死都不会说的 - -!)
贴代码:
using System;using Android.App;using Android.Content;using Android.Widget;using Android.OS;namespace App3{ [Activity(Label = "App3", MainLauncher = true, Icon = "@drawable/icon")] public class MainActivity : Activity { public static String ACTION_BTN = "com.example.notification.btn.login"; public static String INTENT_NAME = "btnid"; public const int INTENT_BTN_LOGIN = 1; static NotificationBroadcastReceiver mReceiver; public static NotificationManager NotifyManager; protected override void OnCreate(Bundle bundle) { base.OnCreate(bundle); // Set our view from the "main" layout resource SetContentView(Resource.Layout.Main); Button button = (Button)FindViewById(Resource.Id.btn_notification); button.Click += (sender, e) => { notification(); }; } private void intiReceiver() { mReceiver = new NotificationBroadcastReceiver(); IntentFilter intentFilter = new IntentFilter(); intentFilter.AddAction(ACTION_BTN); ApplicationContext.RegisterReceiver(mReceiver, intentFilter); } public void unregeisterReceiver() { if (mReceiver != null) { ApplicationContext.UnregisterReceiver(mReceiver); mReceiver = null; } } private void notification() { unregeisterReceiver(); intiReceiver(); RemoteViews remoteViews = new RemoteViews(PackageName, Resource.Layout.notification); remoteViews.SetTextViewText(Resource.Id.tv_up, "首都机场精品无线"); remoteViews.SetTextViewText(Resource.Id.tv_down, "已免费接入"); Intent intent = new Intent(ACTION_BTN); intent.PutExtra(INTENT_NAME, INTENT_BTN_LOGIN); PendingIntent intentpi = PendingIntent.GetBroadcast(this, 1, intent, PendingIntentFlags.UpdateCurrent); remoteViews.SetOnClickPendingIntent(Resource.Id.btn_login, intentpi); Intent intent2 = new Intent(); intent2.SetClass(this, typeof(MainActivity)); intent2.SetFlags(ActivityFlags.NewTask | ActivityFlags.ClearTask); PendingIntent intentContent = PendingIntent.GetActivity(this, 0, intent2, PendingIntentFlags.UpdateCurrent); Notification.Builder builder = new Notification.Builder(this); builder.SetOngoing(false); builder.SetAutoCancel(false); builder.SetContent(remoteViews); builder.SetTicker("正在使用首都机场无线"); builder.SetSmallIcon(Resource.Drawable.id_airport); Notification notification = builder.Build(); notification.Defaults = NotificationDefaults.Sound; notification.Flags = NotificationFlags.NoClear; notification.ContentIntent = intentContent; NotifyManager = (NotificationManager)GetSystemService(Context.NotificationService); NotificationManager notificationManager = NotifyManager; notificationManager.Notify(0, notification); } class NotificationBroadcastReceiver : BroadcastReceiver { public override void OnReceive(Context context, Intent intent) { String action = intent.Action; if (action.Equals(ACTION_BTN)) { int btn_id = intent.GetIntExtra(INTENT_NAME, 0); switch (btn_id) { case INTENT_BTN_LOGIN: Toast.MakeText(context, "从通知栏点登录", ToastLength.Short).Show(); if (mReceiver != null) { context.ApplicationContext.UnregisterReceiver(mReceiver); mReceiver = null; } NotificationManager notificationManager = NotifyManager; notificationManager.Cancel(0); break; } } } } }}
