Notification(一个)——使用演示样本的基础知识

main.xml如下面:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    <Button

        android:id="@+id/button"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="@string/button"

        android:textSize="20sp"

        android:layout_centerInParent="true"

        />

</RelativeLayout>

another.xml例如以下:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

   >

    <TextView

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="@string/newActivity"

        android:textSize="20sp"

        android:layout_centerInParent="true"

        />

</RelativeLayout>

MainActivity例如以下:

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.app.Activity;

import android.app.Notification;

import android.app.NotificationManager;

import android.app.PendingIntent;

import android.content.Intent;

/**

 * Demo描写叙述:发送系统通知

 * 注意:

 * 1 PendingIntent的使用

 * 2 权限申请

 */

public class MainActivity extends Activity {

    private Button mButton;

    private final int FIRST=1;

    private final int SECOND=2;

	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.main);

		init();

	}

    private void init(){

    	mButton=(Button) findViewById(R.id.button);

    	mButton.setOnClickListener(new ButtonOnClickListenerImpl());

    }

    private class ButtonOnClickListenerImpl implements OnClickListener{

		@Override

		public void onClick(View v) {

          NotificationManager manager=(NotificationManager) getSystemService(NOTIFICATION_SERVICE);

          Intent firstIntent=new Intent();

          PendingIntent firstPendingIntent=PendingIntent.getActivity(MainActivity.this, 0, firstIntent, 0);

          Notification firstNotification=new Notification();

          //设置通知的图标

          firstNotification.icon=R.drawable.ic_launcher;

          //设置状态栏的通知提示信息

          firstNotification.tickerText=getResources().getString(R.string.firstNotification_ticker);

          //设置通知发送时间

          firstNotification.when=System.currentTimeMillis();

          //採用系统默认的声音,震动,闪光灯

          firstNotification.defaults=Notification.DEFAULT_ALL;

          //打开应用程序后图标消失

          firstNotification.flags|=Notification.FLAG_AUTO_CANCEL;

          //设置通知的标题和内容,以及点击通知后的对应操作.此处无操作.

          //注意:假设将该方法最后一个參数设置为null,则报错

          firstNotification.setLatestEventInfo(MainActivity.this,

        		  getResources().getString(R.string.firstNotification_title),

        		  getResources().getString(R.string.firstNotification_content),

        		  firstPendingIntent);

          //发送第一个通知

          manager.notify(FIRST, firstNotification);

          Intent secondIntent=new Intent(MainActivity.this,AnotherActivity.class);

          PendingIntent secondPendingIntent=PendingIntent.getActivity(MainActivity.this, 0, secondIntent, 0);

          Notification secondNotification=new Notification();

          //设置通知的图标

          secondNotification.icon=R.drawable.ic_launcher;

          //设置状态栏的通知提示信息

          secondNotification.tickerText=getResources().getString(R.string.secondNotification_ticker);

          //设置通知发送时间

          secondNotification.when=System.currentTimeMillis();

          //採用系统默认的声音,震动,闪光灯

          secondNotification.defaults=Notification.DEFAULT_ALL;

          //打开应用程序后图标消失

          secondNotification.flags|=Notification.FLAG_AUTO_CANCEL;

          //设置通知的标题和内容,以及点击通知后的对应操作.此处为打开指定的Activity

          //注意:假设将该方法最后一个參数设置为null,则报错

          secondNotification.setLatestEventInfo(MainActivity.this,

        		  getResources().getString(R.string.secondNotification_title),

        		  getResources().getString(R.string.secondNotification_content),

        		  secondPendingIntent);

         //发送第二个通知

          manager.notify(SECOND, secondNotification);

		}

    }

}

AnotherActivity例如以下:

import android.app.Activity;

import android.os.Bundle;

public class AnotherActivity extends Activity {

	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.another);

	}

}
