一:先来效果图
二:实现步骤
1.xml布局实现
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="edu.feicui.notification.MainActivity">
<Button
android:id="@+id/btn_create"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="发送通知"
android:textSize="25sp" />
</LinearLayout>
2.activity的实现
package edu.feicui.notification;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.RemoteViews;
import butterknife.ButterKnife;
import butterknife.OnClick;
public class MainActivity extends AppCompatActivity {
private NotificationManager mManager;
private Notification mNotification;
private PendingIntent mIntent;
private String cll;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
cll = "今年27号过年哟!";
ButterKnife.bind(this);
}
@Override
public void onContentChanged() {
super.onContentChanged();
init();
}
private void init() {
//初始化通知栏管理者
mManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
//意图数组
Intent[] intents = {new Intent(this, NotificationAcitivity.class)};
//待处理意图对象
mIntent = PendingIntent.getActivities(this, 0, intents, 0);
//消息栏通知对象
mNotification = new Notification();
}
@OnClick(R.id.btn_create)
public void create() {
//设置在通知栏的消息图标
mNotification.icon = R.mipmap.logo_new;
//设置在通知栏的信息内容
mNotification.tickerText = "重大消息";
//设置默认的声音,此外还可以设置震动(需加入权限)
mNotification.defaults = Notification.DEFAULT_SOUND;
//添加灯光
// mNotification.defaults=Notification.DEFAULT_LIGHTS;
//不能删除
mNotification.flags = Notification.FLAG_NO_CLEAR;
//设置下拉时的显示布局
RemoteViews convertView = new RemoteViews(getPackageName(), R.layout.layout_content);
convertView.setImageViewResource(R.id.img, R.mipmap.logo_new);
convertView.setTextViewText(R.id.txt, cll);
mNotification.contentView = convertView;
mNotification.contentIntent = mIntent;
//发送通知
// 第一个参数唯一的标识该Notification,第二个参数就是Notification对象
mManager.notify(1, mNotification);
}
}
3.AndroidManifest添加权限
<uses-permission android:name="android.permission.VIBRATE"/>
4.跳转界面的xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical">
<TextView
android:id="@+id/txt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#ff0000"
android:textSize="20dp"
android:text="今年27号过年哟!" />
</LinearLayout>
5.跳转activity的实现
package edu.feicui.notification;
import android.app.Activity;
import android.app.NotificationManager;
import android.os.Bundle;
import android.widget.TextView;
public class NotificationAcitivity extends Activity {
private NotificationManager mManager;
private int index = 2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notification);
//初始化通知栏管理者
mManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
index = 2;
mManager.cancelAll();
}
}
