<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" android:layout_width="fill_parent"
	android:layout_height="fill_parent">
	<Button android:text="Button" android:id="@+id/button1"
		android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</LinearLayout>

两个Activity


package com.tcl.testnotifycation;

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 TestNotificationActivity extends Activity {
	private NotificationManager mNotificationManager;
	private PendingIntent mPendingIntent;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
		// 点击通知切换到Activity2
		Intent intent = new Intent(this, Activity2.class);
		mPendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
		Button button = (Button) findViewById(R.id.button1);
		button.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				Notification notification = new Notification();
				notification.icon = R.drawable.icon;// 显示图标
				notification.tickerText = "test...";// 点击通知用户的内容
				notification.defaults = Notification.DEFAULT_SOUND;// 默认声音
				// 通知时震动
				// notification.defaults = Notification.DEFAULT_VIBRATE;
				// 通知时屏幕发亮
				// notification.defaults = Notification.DEFAULT_LIGHTS;
				notification.setLatestEventInfo(TestNotificationActivity.this,
						"myNotification", "test test test", mPendingIntent);
				mNotificationManager.notify(0, notification);
			}
		});

	}
}


package com.tcl.testnotifycation;

import com.tcl.testnotifycation.R.layout;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;

public class Activity2 extends Activity{
	public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        LinearLayout layout = new LinearLayout(this);
        TextView textView = new TextView(this);
        textView.setText("this is test notifycation");
        layout.addView(textView);
        setContentView(layout);
	}
