java - 如何在 Android 中将图像从 drawable 设置为 imageview

Question

我想将图像显示到 RecyclerView 中，我应该使用 drawable 文件夹中的图像。我写了下面的代码，但显示了这个错误:

java.lang.IllegalArgumentException: Unknown type class [I. You must provide a Model of a type for which there is a registered ModelLoader, if you are using a custom model, you must first call Glide#register with a ModelLoaderFactory for your custom model class

模型代码:

public class MainDataModel implements Serializable {

    private static final long serialVersionUID = 1L;
    private String category;
    private String categoryID;
    private String categoryDescription;
    private int[] categoryImages;

    private TimeInterpolator interpolator;

    public MainDataModel(String categoryID, String category, String categoryDescription, int[] categoryImages,
                         TimeInterpolator interpolator) {
        this.categoryID = categoryID;
        this.category = category;
        this.categoryDescription = categoryDescription;
        this.categoryImages = categoryImages;
        this.interpolator = interpolator;
    }

    public String getCategory() {
        return category;
    }

    public void setCategory(String category) {
        this.category = category;
    }

    public String getCategoryID() {
        return categoryID;
    }

    public void setCategoryID(String caategoryID) {
        this.categoryID = caategoryID;
    }

    public String getCategoryDescription() {
        return categoryDescription;
    }

    public void setCategoryDescription(String categoryDescription) {
        this.categoryDescription = categoryDescription;
    }

    public TimeInterpolator getInterpolator() {
        return interpolator;
    }

    public void setInterpolator(TimeInterpolator interpolator) {
        this.interpolator = interpolator;
    }

    public int[] getCategoryImages() {
        return categoryImages;
    }

    public void setCategoryImages(int[] categoryImages) {
        this.categoryImages = categoryImages;
    }

}

AsyncTask代码和设置图片:

public class ColoniesDataInfo {

    private static Context mContext;
    private String ServerAddress = ServerIP_colonies.getColoniesIP();

    public void getColoniesDataInfo(Context context) {
        mContext = context;
        new getInfo().execute(ServerAddress);
    }

    private class getInfo extends AsyncTask<String, Void, String> {
        EventBus bus = EventBus.getDefault();
        private String ou_response;
        private List<MainDataModel> infoModels;

        @Override
        protected void onPreExecute() {
            CustomProcessDialog.createAndShow(mContext);
            infoModels = new ArrayList<>();
        }

        @Override
        protected String doInBackground(String... params) {
            OkHttpClient client = new OkHttpClient();

            //String url = (String) params[0];
            Request request = new Request.Builder()
                    .url(ServerAddress)
                    //.cacheControl(CacheControl.FORCE_NETWORK)
                    .build();

            Response response;
            try {
                response = client.newCall(request).execute();
                ou_response = response.body().string();
                response.body().close();
                if (ou_response != null) {
                    try {
                        JSONObject postObj = new JSONObject(ou_response);
                        JSONArray postsArray = postObj.optJSONArray("categories");
                        infoModels = new ArrayList<>();

                        for (int i = 0; i <= infoModels.size(); i++) {
                            JSONObject postObject = (JSONObject) postsArray.get(i);

                            String colID = postObject.getString("id");
                            String colTitle = postObject.getString("title");
                            String colDescription = postObject.getString("description");

                            final int[] colImages = {
                                    R.drawable.colonies_image_food,
                                    R.drawable.colonies_image_medical,
                                    R.drawable.colonies_image_tecgnolegy,
                                    R.drawable.colonies_image_entertenement,
                                    R.drawable.colonies_image_car,

                                    R.drawable.colonies_image_sport,
                            };

                            Log.d("Data", "Colonies ID: " + colID);
                            Log.d("Data", "Colonies title: " + colTitle);
                            Log.d("Data", "Colonies Desc: " + colDescription);
                            Log.d("Data", "---------------------------------");

                            //Use the title and id as per your requirement
                            infoModels.add(new MainDataModel(colID, colTitle, colDescription, colImages,
                                    Utils.createInterpolator(Utils.BOUNCE_INTERPOLATOR)));
                        }

                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            return ou_response;
        }

        @Override
        protected void onPostExecute(String result) {
            CustomProcessDialog.dissmis();
            if (result != null) {
                bus.post(infoModels);
            } else {
                Toast.makeText(mContext, "Empty", Toast.LENGTH_SHORT).show();
            }
        }
    }
}

适配器代码和设置图像到适配器:

public class ColoniesAdapter extends RecyclerView.Adapter<ColoniesAdapter.ViewHolder> {

    private List<MainDataModel> mDateSet;
    private Context mContext;
    private SparseBooleanArray expandState = new SparseBooleanArray();

    public ColoniesAdapter(Context context, List<MainDataModel> dataSet) {
        this.mContext = context;
        this.mDateSet = dataSet;
        for (int i = 0; i < mDateSet.size(); i++) {
            expandState.append(i, false);
        }
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        View view = LayoutInflater.from(mContext).inflate(R.layout.colonies_row, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(final ViewHolder holder, final int position) {

        holder.colonies_title.setText(mDateSet.get(position).getCategory());
        holder.colonies_title.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int pos = holder.getPosition();
                MainDataModel model = mDateSet.get(pos);
                v.getContext().startActivity(new Intent(v.getContext(), Category_page.class)
                        .putExtra("categoryTitle", model.getCategory())
                        .putExtra("categoryID", model.getCategoryID()));
            }
        });

        Glide.with(mContext)
                .load(mDateSet.get(position).getCategoryImages())
                .placeholder(R.drawable.post_image)
                .crossFade()
                .override(700, 400)
                .into(holder.colonies_image);
        holder.colonies_description.setText(mDateSet.get(position).getCategoryDescription());

        holder.expandableLayout.setInterpolator(mDateSet.get(position).getInterpolator());
        holder.expandableLayout.setExpanded(expandState.get(position));
        holder.expandableLayout.setListener(new ExpandableLayoutListenerAdapter() {
            @Override
            public void onPreOpen() {
                createRotateAnimator(holder.buttonLayout, 0f, 180f).start();
                expandState.put(position, true);
            }

            @Override
            public void onPreClose() {
                createRotateAnimator(holder.buttonLayout, 180f, 0f).start();
                expandState.put(position, false);
            }
        });
        holder.buttonLayout.setRotation(expandState.get(position) ? 180f : 0f);
        holder.buttonLayout.setOnClickListener(new View.OnClickListener() {

    }

    private void onClickButton(final ExpandableLayout expandableLayout) {
        expandableLayout.toggle();
    }

    @Override

我该如何解决？

Answer 1

首先，为什么要将所有图像数组加载到单个 imageView 中？您的方法 getCategoryImages() 为您提供图像的整数数组。一个一个的检索对应的位置。

如果问题仍然存在，您可以引用以下相同问题的链接

https://github.com/bumptech/glide/issues/588

Glide.with(mContext)
            .load(mDateSet.get(position).getCategoryImages()[position])
            .placeholder(R.drawable.post_image)
            .crossFade()
            .override(700, 400)
            .into(holder.colonies_image);
