Android Studio错误:java.lang.ArrayIndexOutOfBoundsException:长度=5；索引=5

Question

我的RecyclerView不工作。当我启动我的应用程序时，它就会崩溃，因为它无法形成recyclerview。不幸的是，我没有发现错误。也许你们中的一个能找到。有人能帮我解决这个问题吗？谢谢所有的答案:）。我使用下面的代码遇到了这个错误:

Error Code: java.lang.ArrayIndexOutOfBoundsException: length=5; index=5

ArrayList:

    public static ArrayList<HandySearchModel> getListData() {
        HandySearchModel handySearchModel;
        ArrayList<HandySearchModel> list = new ArrayList<>();

        for (String[] mData : data) {
            handySearchModel = new HandySearchModel();

            handySearchModel.setBrand(mData[0]);
            handySearchModel.setHandyName(mData[1]);
            handySearchModel.setPhoto(mData[2]);
            handySearchModel.setDisplay(mData[3]);
            handySearchModel.setDisplaySize(mData[4]);
            handySearchModel.setMainCamera(mData[5]);
            handySearchModel.setMaxResolution(mData[6]);
            handySearchModel.setRam(mData[7]);
            handySearchModel.setProcessor(mData[8]);
            handySearchModel.setBatteryCapacity(mData[9]);
            handySearchModel.setBatteryType(mData[10]);

            list.add(handySearchModel);
        }

        return list;
    }

型号:

    public class HandySearchModel implements Parcelable {

    // create implementation Parcelable to this class

    private String photo, brand, handyName, display, displaySize, mainCamera, maxResolution, ram, processor, batteryCapacity, batteryType;

    public String getBrand() {
        return brand;
    }
    public void setBrand(String brand) {
        this.brand = brand;
    }

    public String getHandyName() {
        return handyName;
    }
    public void setHandyName(String handyName) {
        this.handyName = handyName;
    }

    public String getDisplay() {
        return display;
    }
    public void setDisplay(String display) {
        this.display = display;
    }

    public String getDisplaySize() {
        return displaySize;
    }
    public void setDisplaySize(String displaySize) {
        this.displaySize = displaySize;
    }

    public String getMainCamera() {
        return mainCamera;
    }
    public void setMainCamera(String mainCamera) {
        this.mainCamera = mainCamera;
    }

    public String getMaxResolution() {
        return maxResolution;
    }
    public void setMaxResolution(String maxResolution) {
        this.maxResolution = maxResolution;
    }

    public String getRam() {
        return ram;
    }
    public void setRam(String ram) {
        this.ram = ram;
    }

    public String getProcessor() {
        return processor;
    }
    public void setProcessor(String processor) {
        this.processor = processor;
    }

    public String getBatteryCapacity() {
        return batteryCapacity;
    }
    public void setBatteryCapacity(String batteryCapacity) {
        this.batteryCapacity = batteryCapacity;
    }

    public String getBatteryType() {
        return batteryType;
    }
    public void setBatteryType(String batteryType) {
        this.batteryType = batteryType;
    }

    public String getPhoto() {
        return photo;
    }
    public void setPhoto(String photo) {
        this.photo = photo;
    }


    public HandySearchModel() {
    }

    protected HandySearchModel(Parcel in) {


        photo = in.readString();
        brand = in.readString();
        handyName = in.readString();
        display = in.readString();
        displaySize = in.readString();
        mainCamera = in.readString();
        maxResolution = in.readString();
        ram = in.readString();
        processor = in.readString();
        batteryCapacity = in.readString();
        batteryType = in.readString();
    }

    public static final Creator<HandySearchModel> CREATOR = new Creator<HandySearchModel>() {
        @Override
        public HandySearchModel createFromParcel(Parcel in) {
            return new HandySearchModel(in);
        }

        @Override
        public HandySearchModel[] newArray(int size) {
            return new HandySearchModel[size];
        }
    };

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

    @Override
    public void writeToParcel(Parcel parcel, int i) {

        parcel.writeString(photo);
        parcel.writeString(brand);
        parcel.writeString(handyName);
        parcel.writeString(display);
        parcel.writeString(displaySize);
        parcel.writeString(mainCamera);
        parcel.writeString(maxResolution);
        parcel.writeString(ram);
        parcel.writeString(processor);
        parcel.writeString(batteryCapacity);
        parcel.writeString(batteryType);
    }
}

创建列表:

    private void createList() {
        list = new ArrayList<>();
        list.addAll(HandyData.getListData());
    }

Answer 1

您的错误是告诉您正在尝试访问大小为5的数组中的索引号5。问题是，数组从零开始，因此对于您的5大小数组，可用的索引是0，1，2，3和4。该数组中不存在索引号5，因此您将获得异常（ArrayIndexOutOfBoundsException）。

直观地解释，这是您的数组:[pos_0][pos_1][pos_2][pos_3][pos_4]

您想要访问不存在的pos_5。
