在活动和服务之间共享数据android

Question

我正在做一个android应用程序，我想从活动中获取数据到服务 ，然后此服务将发出通知并将数据发送到其他活动，用户可以看到结果活动？请HEP我

Answer 1

写在活动从那里你要发送的数据：（MSG是您要发送的数据）的接收机活动

Intent myintent = new Intent("package name of class where you want to send"); 
    myintent.putExtra("message", msg); 
    myintent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//You might need this 
    getApplicationContext().sendBroadcast(myintent); 

在的onCreate（）： 补充一点：（任何地方设置内容视图）后

  getApplicationContext().registerReceiver(broadcastReceiver, new IntentFilter("package name of current class i.e receiver")); 

类补充一点：

private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() { 
    @Override 
    public void onReceive(Context context, Intent intent) { 
      Log.d(TAG, "Data received is : " + intent.getStringExtra("message")); 
    //Make a Notification here 
    } 
}; 

铝所以（在接收器活动中）：

@Override 
public void onResume() { 
    super.onResume(); 
    getApplicationContext().registerReceiver(broadcastReceiver, new IntentFilter("package name of current class i.e receiver")); 
} 

protected void onPause() { 
    super.onPause(); 
    getApplicationContext().unregisterReceiver(broadcastReceiver); 
}
