Question

我尝试在countDown中从AudioRecord获取val但是当我在Activity中获得额外的列表时，包含相同的值（我已经检查过AudioRecord返回了不同的值）。请帮我！。提前致谢。注意：我调用countDown传递45 * 1000和100

// Class of CountDownTimer
dataValues = new ArrayList<Data>();
(MenuActivity)context).runOnUiThread(new Runnable() {
        @Override
        public void run() {
            new CountDownTimer(millis, intervalInMillis){
                @Override
                public void onTick(long millisUntilFinished) {
                        firstValues.add(val); // val from AudioRecord
                   if (firstValues.size() >=10){
                        firstValues.remove(0);
                        data.setValue(avgFromIntList(firstValues));
                        data.setTime(new Date().getTime());
                        dataValues.add(data);

                    }
                }

                @Override
                public void onFinish() {
                    Bundle extras = new Bundle();

                    extras.putLong("idSession", session.getId());
                    extras.putParcelableArrayList("values",dataValues);

                    Intent toPast = new Intent(context, SessionPastActivity.class);
                    toPast.putExtras(extras);
                    context.startActivity(toPast);

                }
            }.start();
        }
    });


// Model class that implement Parcelable

public class Data实现了Parcelable {

private Integer value; 
private Long time;

public Data(Integer value, Long time) {
    this.value = value;
    this.time = time;
}

public Data() {
}



public Integer getValue() {
    return value;
}

public void setValue(Integer value) {
    this.value = value;
}

public Long getTime() {
    return time;
}

public void setTime(Long time) {
    this.time = time;
}



@Override
public String toString() {
    return "Data{" +
            ", value=" + value +
            ", time=" + time +
            '}';
}

@Override
public int describeContents() {
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {

    dest.writeInt(value);
    dest.writeLong(time);

    Log.e("inWrite", toString());
}

// this is used to regenerate your object. All Parcelables must have a CREATOR that implements these two methods
public static final Parcelable.Creator<Data> CREATOR = new Parcelable.Creator<Data>() {
    public Data createFromParcel(Parcel in) {
        return new Data(in);
    }

    public Data[] newArray(int size) {
        return new Data[size];
    }
};

// example constructor that takes a Parcel and gives you an object populated with it's values
private Data(Parcel in) {

    value = in.readInt();
    time = in.readLong();

    Log.e("inREAD", toString());
}

//活动类

ArrayList values_amplitude = getIntent（）。getExtras（）。getParcelableArrayList（“values”）;

Answer 1

试试这个

Bundle bundle=getIntent.getExtra();

    if(bundle != null){
    ArrayList<Data> values_amplitude = (ArrayList<Data>).getParcelable("values");
    } else {}

希望它对您有用

CountDownTimer中的android- putParcelableArrayList在返回的List上放置相同的值
