	<TextView android:layout_width="fill_parent"
		android:layout_height="wrap_content" android:text="@string/hello" />
	<Button android:text="Button01" android:id="@+id/Button01"
		android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>

</LinearLayout>

package com.Aina.Android;

import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class Test_Notification extends Activity {
	/** Called when the activity is first created. */
	private Button btn1;
	private Notification notification;
	private NotificationManager notificationManager;
	private Intent intent;
	private PendingIntent pendIntent;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		btn1 = (Button) this.findViewById(R.id.Button01);
		notificationManager = (NotificationManager) this
				.getSystemService(NOTIFICATION_SERVICE);// 获取系统服务（消息管理）
		// 点击通知时转移内容
		intent = new Intent(this, Activity2.class);
		// 设置点击通知时显示内容的类
		pendIntent = PendingIntent.getActivity(this, 0, intent, 0);
		notification = new Notification();
		btn1.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				notification.icon = R.drawable.img1;// 设置在状态栏显示的图标
				notification.tickerText = "Button1通知内容.......";//设置在状态栏显示的内容
				notification.defaults = Notification.DEFAULT_SOUND;// 默认的声音
				// 设置通知显示的参数
				notification.setLatestEventInfo(Test_Notification.this,
						"Button1", "Button1通知", pendIntent);
				notificationManager.notify(0, notification);// 执行通知.
			}

		});
	}
