在主活动中实现按钮弹出通知
在的onCreate中首先绑定按钮
Button sendNotice = (Button)findViewById(R.id.button_send_notice);
sendNotice.setOnClickListener(this);
的onClick
@Override
public void onClick(View view) {
//判断sdk 当app版本为O或者以上时创建通知渠道
if(Build.VERSION.SDK_INT >= 26)
createChannel();
switch (view.getId()){
case R.id.button_send_notice:
Intent intent = new Intent(this, NotificationActivity.class);
PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0);
Notification notification = new NotificationCompat.Builder(this, "channel_01")
.setContentTitle("This is content title")
.setContentText("Tis is content")
.setWhen(System.currentTimeMillis())
.setSmallIcon(R.mipmap.ic_launcher)
.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
.setContentIntent(pi)
.build();
NotificationManager manager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
manager.notify(1, notification);
break;
default:
break;
}
}
创建通知渠道的函数封装
@RequiresApi(api=26)
public void createChannel(){
NotificationManager manager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
//通知渠道组的id
String group = "group_id";
// 用户可见的通知渠道组名称.
CharSequence group_name = getString(R.string.group_name);
//创建通知渠道组
manager.createNotificationChannelGroup(new NotificationChannelGroup(group, group_name));
/**
* 创建通知渠道1
*/
//渠道id
String id = "channel_01";
//用户可以看到的通知渠道的名字
CharSequence name = getString(R.string.channel_name);
//用户可以看到的通知渠道的描述
String description = getString(R.string.channel_description);
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel channel = new NotificationChannel(id, name, importance);
//配置通知渠道的属性
channel.setDescription(description);
//设置通知出现时的闪灯(如果android设备支持的话)
channel.enableLights(true);
channel.setLightColor(Color.GREEN);
//设置通知出现时的震动(如果androd设备支持的话)
channel.enableVibration(true);
channel.setVibrationPattern(new long[]{100, 200, 300, 400, 500});
//绑定通知渠道组
channel.setGroup(group);
//在notificationmanager中创建该通知渠道
manager.createNotificationChannel(channel);
