android开发 最新情况,Android之开发消息通知栏

一：先来效果图

二：实现步骤

1.xml布局实现

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">

android:id="@+id/btn_create"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="发送通知"

android:textSize="25sp" />

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 {

/**

* 通知栏Notification

*/

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

4.跳转界面的xml

android:layout_width="match_parent"

android:layout_height="match_parent"

android:gravity="center"

android:orientation="vertical">

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!" />

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;

/**

* Created by Administrator on 2017-1-20.

*/

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();

}

}
