Notification状态栏通知
Notification分为普通通知和自定义的两种，由图标、ticker(提示信息)、标题、内容、时间、事件组成，
普通通知demo：
1 package com.android.hzynotification; 2 3 import android.app.Activity; 4 import android.app.Notification; 5 import android.app.NotificationManager; 6 import android.app.PendingIntent; 7 import android.content.Context; 8 import android.content.Intent; 9 import android.os.Bundle; 10 import android.view.View; 11 12 public class MainActivity extends Activity { 13 14 @Override 15 protected void onCreate(Bundle savedInstanceState) { 16 super.onCreate(savedInstanceState); 17 setContentView(R.layout.activity_main); 18 } 19 20 public void send(View v){ 21 // 1.得到通知管理器 22 NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 23 // 2.构建通知 24 Notification notification = new Notification(android.R.drawable.stat_notify_chat, "这是提示信息", System.currentTimeMillis()); 25 // 3.设置通知点击事件 26 Intent intent = new Intent(this,MainActivity.class); 27 PendingIntent contentIntent = PendingIntent.getActivity(this, 100, intent, 0); 28 notification.setLatestEventInfo(this, "通知的标题", "通知的内容", contentIntent); 29 30 notification.flags = Notification.FLAG_AUTO_CANCEL; // 点击通知后自动消失 31 32 // 4.发送通知 33 nm.notify(100, notification); 34 } 35 }
自定义通知的布局设置：
1 <?xml version="1.0" encoding="utf-8"?> 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 3 android:layout_width="match_parent" 4 android:layout_height="match_parent" 5 android:orientation="horizontal" > 6 7 <ImageView 8 android:layout_width="wrap_content" 9 android:layout_height="wrap_content" 10 android:src="@drawable/ic_launcher" 11 /> 12 <LinearLayout 13 android:layout_marginLeft="3dp" 14 android:layout_width="match_parent" 15 android:layout_height="wrap_content" 16 android:orientation="vertical" 17 > 18 <TextView 19 android:layout_marginTop="2dp" 20 android:layout_width="wrap_content" 21 android:layout_height="wrap_content" 22 android:text="自定义的通知,专业拦截器" 23 /> 24 <ProgressBar 25 android:layout_marginTop="2dp" 26 android:layout_width="match_parent" 27 android:layout_height="wrap_content" 28 style="@android:style/Widget.ProgressBar.Horizontal" 29 /> 30 </LinearLayout> 31 32 33 </LinearLayout>
自定义通知代码如下：
1 package com.android.hzynotification; 2 import android.app.Activity; 3 import android.app.Notification; 4 import android.app.NotificationManager; 5 import android.app.PendingIntent; 6 import android.content.Context; 7 import android.content.Intent; 8 import android.os.Bundle; 9 import android.view.View; 10 import android.widget.RemoteViews; 11 12 public class MainActivity extends Activity { 13 14 @Override 15 protected void onCreate(Bundle savedInstanceState) { 16 super.onCreate(savedInstanceState); 17 setContentView(R.layout.activity_main); 18 } 19 20 21 public void costom(View v){ 22 // 1.得到通知管理器 23 NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 24 // 2.构建通知 25 Notification notification = new Notification(); 26 notification.icon = android.R.drawable.stat_notify_missed_call; // 图标 27 notification.tickerText = "有未接电话哦"; 28 29 RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.content); 30 notification.contentView = contentView; // 设置通知显示的布局 31 32 // 设置通知点击的事件 33 Intent intent = new Intent(this,OtherActivity.class); 34 PendingIntent contentIntent = PendingIntent.getActivity(this, 100, intent, 0); 35 notification.contentIntent = contentIntent; 36 37 // 设置点击通知后自动消失 38 notification.flags = Notification.FLAG_AUTO_CANCEL; 39 // 发出通知 40 nm.notify(100, notification); 41 42 } 43 }
