Question

我正在创建一个使用EEG NeuroSky耳机的应用程序，该耳机测量用户在玩游戏时的特定时间段内的注意力和中介级别。

从耳机记录关注和调解级别，并每秒在屏幕上实时显示（0到100之间的整数）。它与神经网络应用程序非常相似here

我希望能够保存它们，然后在游戏结束后在单独的Activity中查看它们，无论是int值还是图形形式。即能够查看用户调解级别为36秒，注意级别为45秒等等。

是否可以这样做，如果是这样，怎么做？

特定关注领域：

注意 - 我不知道如何保存每个msg.arg1的值？

case TGDevice.MSG_MEDITATION:
                meditation.setText("Meditation: " + msg.arg1 + "\n");

                if(msg.arg1<=35){

                    //if mediation level is low it turns red
                    meditation.setBackgroundColor(Color.RED);

                }else if((msg.arg1<=70)&&(msg.arg1>=35)){
                      meditation.setBackgroundColor(Color.YELLOW);
                    }else{

                        meditation.setBackgroundColor(Color.GREEN);
                    }

                break;

记录数据的代码：

/**
     * Handles messages from TGDevice
     * 
     */
    final Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {

            // msg.what determines the type of each message
            switch (msg.what) {
            case TGDevice.MSG_EEG_POWER:

                //WILL NEED TO CHANGE TO PUTPUT TO SCREEN. 
//              Log.d("LSD", "highAlpha: " + eegPower.highAlpha);
//              Log.d("LSD", "lowAlpha: " + eegPower.lowAlpha);
//              Log.d("LSD", "highBeta: " + eegPower.highBeta);
//              Log.d("LSD", "lowBeta: " + eegPower.lowBeta);

                break;
            case TGDevice.MSG_STATE_CHANGE:

Answer 1

System.currentTimeMillis()

为系统时钟设置的系统时间为unix时间戳

如何在Android应用程序中保存实时数据以便以后查看？
