Android Notification状态栏通知 _Notification

【Android Notification状态栏通知】寸阳分阴须爱惜，休负春色与时光。这篇文章主要讲述Android Notification状态栏通知相关的知识，希望能为你提供帮助。
没有添加额外的震动及声音效果，这里直接实现了通知的功能，看效果吧：MainActivity.java

package com.example.notification; import android.os.Bundle; import android.annotation.SuppressLint; import android.app.Activity; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.content.res.Resources; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.view.Menu; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class MainActivity extends Activity {public NotificationManager mNotificationManager; @SuppressLint("NewApi") @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Button btn = (Button) findViewById(R.id.button1); btn.setOnClickListener(new OnClickListener() {@Override public void onClick(View v) { // TODO Auto-generated method stub // 1-获得MotificationManager的引用。String ns = Context.NOTIFICATION_SERVICE; mNotificationManager = (NotificationManager) getSystemService(ns); // 2-实例化Notification：int icon = R.drawable.new_mail; CharSequence tickerText = "Hello"; long when = System.currentTimeMillis(); Notification notification = new Notification(icon, tickerText, when); // 3-定义Notification，如显示icon、目标intent等信息Context context = getApplicationContext(); CharSequence contentTitle = "My notification"; CharSequence contentText = "Hello World!"; Intent notificationIntent = new Intent(v.getContext(), MessageActivity.class); PendingIntent contentIntent = PendingIntent.getActivity( v.getContext(), 0, notificationIntent, 0); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); // 4-传递给Manager.final int HELLO_ID = 1; mNotificationManager.notify(HELLO_ID, notification); } }); }@Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.activity_main, menu); return true; }}

MessageActivity.java

package com.example.notification; import android.app.Activity; import android.app.NotificationManager; import android.content.Context; import android.os.Bundle; public class MessageActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_message); NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.cancel(1); //这里实现了，点击消息后，自己主动清除消息的功能。 } }

XML布局文件就不写了。非常easy的~这里没有实现通知到达时的提示效果，如震动、提示音之类。将在 Android Notification实现推送消息过程中接受到消息端有声音及震动及亮屏提示文章实现这样的功能
