[Android]_ch11.2_Notification通告訊息元件2

1.呼叫Activity.getSystemService()取得NotificationManager物件

NotificationManager  ntfMgr
= (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);

2.呼叫Notification.Builder建構式建立Notification.Builder物件；再呼叫getNotification()即可建立Notification物件，API
Level 16將getNotification()列為deprecated，並建議改呼叫build()

Notification notification = new Notification.Builder(this)

3.設定通知訊息標題、圖示與內容

  //
通知訊息在狀態列的文字

  .setTicker(getString(R.string.tickerText))

  //
通知訊息在訊息面板的標題

  .setContentTitle(getString(R.string.contentTitle))

  //
通知訊息在訊息面板的內容文字

  .setContentText(getString(R.string.contentText))

  //
通知訊息的圖示

  .setSmallIcon(android.R.drawable.ic_menu_info_details)

btn3.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Intent intent=new Intent(MainActivity.this,Act02.class);

PendingIntent pendingIntent=PendingIntent.getActivity(MainActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

Notification.Builder builder= new Notification.Builder(MainActivity.this);

builder.setTicker("交通大學通知訊息");

builder.setContentTitle("交通大學補班公告");

builder.setContentText("1/19補班補課");

builder.setSmallIcon(R.drawable.icon2);

Resources resources=getResources();

Bitmap bitmap=BitmapFactory.decodeResource(resources, R.drawable.ypu);

builder.setLargeIcon(bitmap);

builder.setContentIntent(pendingIntent);

builder.setWhen(System.currentTimeMillis());

Notification notification=builder.build();

notification.defaults=Notification.DEFAULT_SOUND;

notification.defaults=Notification.DEFAULT_LIGHTS;

notification.defaults=Notification.DEFAULT_VIBRATE;

notification.vibrate=new long[]{100,500,100,500};

nm.notify(id2, notification);

}

});

        btn4.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

nm.cancel(id2);

}

});
