手機APP開發 - Alarm警報

以下紀錄使用Eclipse開發手機APP警報的心得如下

1. 專案開啟後，AndroidManifest.xml中必須在</manifest>之前插入

　<uses-permission android:name="android.permission.VIBRATE" />

　讓程式註冊震動的服務

2. 在layout的activity_main.xml(預設)檔名中加入一個按鈕 [notifyButn]

3. MainActivity.java的程式碼

package com.example.alarmtest;

import android.app.Activity;

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

public class MainActivity extends Activity {
     Button buttonCreateNotification;
   
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            buttonCreateNotification = (Button)findViewById(R.id.notifyButn);
            buttonCreateNotification.setOnClickListener(
                  new Button.OnClickListener(){
                     
                  @Override
                  public void onClick(View arg0) {
                      createNotification(getBaseContext());
                  }}
              );       
        }
       
        private void createNotification(Context context){
         NotificationManager notificationManager
          = (NotificationManager)context.getSystemService(
            Context.NOTIFICATION_SERVICE);
        
         Intent intent = new Intent(context, MainActivity.class);
         PendingIntent pendingIntent
          = PendingIntent.getActivity(context, 0, intent, 0);
        
         long[] vibratepattern = {100, 400, 500, 400};
        
         Notification notification = new Notification.Builder(context)
                 .setSmallIcon(R.drawable.ic_launcher)
                 .setContentTitle("標題")
                 .setContentText("文字")
                 .setContentInfo("信息")
                 .setTicker("票")
                 .setLights(0xFFFFFFFF, 1000, 1000)
                 .setVibrate(vibratepattern)
                 .setContentIntent(pendingIntent)
                 .setAutoCancel(false)
                  .build();
        
         notificationManager.notify(R.drawable.ic_launcher, notification);
        }
}
