Android--使用Notification在通知栏显示消息

  在一个Activity中点击按钮,产生一个通知栏消息通知。

package cn.luxh.mynotice;

import android.os.Bundle;
import android.util.Log;
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; public class MainActivity extends Activity {
private static String TAG = "MyNotice";
private static int notificationID = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
handleBtnDisplayNotification();
} /**
* 点击按钮,创建消息通知
*/
private void handleBtnDisplayNotification() {
Button btnDisplayNotification = (Button) findViewById(R.id.btn_display_notice);
btnDisplayNotification.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Log.i(TAG, "点击按钮");
Intent i = new Intent(MainActivity.this,NoticeViewActivity.class);
i.putExtra("notificationID", notificationID);
PendingIntent pi = PendingIntent.getActivity(MainActivity.this, 0, i, 0);
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); //创建通知对象
Notification n = new Notification.Builder(MainActivity.this)
.setContentTitle("有来自黑莓的新邮件")
.setContentText("黑莓,依然经典!")
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(pi)
.build();
//振动手机
n.vibrate = new long[]{100,250,100,500};
nm.notify(notificationID, n);
}
});
} }
package cn.luxh.mynotice;

import android.app.Activity;
import android.app.NotificationManager;
import android.os.Bundle;
import android.util.Log; /**
* 在通知栏点击通知后显示消息的界面
* @author Luxh
*
*/
public class NoticeViewActivity extends Activity{ private static String TAG = "MyNotice"; @Override
protected void onCreate(Bundle savedInstanceState) {
Log.i(TAG, "NoticeViewActivity onCreate");
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notice_view); NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
//取消通知
nm.cancel(getIntent().getExtras().getInt("notificationID"));
}
}

运行效果:
