java.lang.OutOfMemoryError：位图的大小超过上线Drawable.createFromStream（（（java.io.InputStream中的）新网址（URL），QUOT VM预算;＆QUOT;）在android系统 [英] java.lang.OutOfMemoryError: bitmap size exceeds VM budget on line Drawable.createFromStream(((java.io.InputStream) new URL(url), "") in android

问题描述

首先，我通过解析JSON响应创建图像和图像信息的ArrayList

First I'm creating an Arraylist of images and image information by parsing json response

`JSONArray jsonArray = jsonObj.getJSONArray("result");
                for (int i = 0; i < jsonArray.length(); i++) {
                    JSONObject jsonObjInner = jsonArray.getJSONObject(i);

                    ImageInfo imageInfo = new ImageInfo();
                    imageInfo.setImageUrl("http://www.dvimaytech.com/markphoto/" + jsonObjInner.getString("image"));

                    new GetDrawableFromUrl(imageInfo).execute();

                    imageInfo.setEmail(jsonObjInner.getString("emailid"));
                    imageInfo.setImage_id(jsonObjInner.getString("image_id"));
                    imageInfo.setImage_name(jsonObjInner.getString("image_name"));
                    imageInfo.setAmount(jsonObjInner.getString("amount"));
                    imageInfo.setImage_description(jsonObjInner.getString("image_description"));
                    imageInfo.setDate_created(jsonObjInner.getString("date_created"));
                }`

然后，我开始使用code从服务器映像另一个异步任务

Then I get images from server another in Async task using the code

public class GetDrawableFromUrl extends AsyncTask<Void, Void, Drawable> {
    public ImageInfo imageInfoObj;

    GetDrawableFromUrl(ImageInfo imageInfo) {
        imageInfoObj = imageInfo;
    }

    @Override
    protected Drawable doInBackground(Void... params) {
        try {
            return Drawable.createFromStream(((java.io.InputStream) new java.net.URL(imageInfoObj.getImageUrl()).getContent()), "src_name");
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    protected void onPostExecute(Drawable drawable) {
        if (drawable != null) {
            imageInfoObj.setImage(drawable);
            listImageInfo.add(imageInfoObj);
            showImagesInList();
        }
    }
}

我的适配器类code

My adapter class code

public class MyImageListAdapter extends BaseAdapter {

    private LayoutInflater inflater = null;

    public MyImageListAdapter() {
        inflater = (LayoutInflater) HomeActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    public int getCount() {
        return listImageInfo.size();
    }

    public Object getItem(int position) {
        return listImageInfo.get(position);
    }

    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        View vi = convertView;
        if (convertView == null) {
            vi = inflater.inflate(R.layout.list_row, null);
        }

        TextView tvName = (TextView) vi.findViewById(R.id.tv_name);
        TextView tvTime = (TextView) vi.findViewById(R.id.tv_time);
        ImageView image = (ImageView) vi.findViewById(R.id.iv_image);
        final Button btnDelete = (Button) vi.findViewById(R.id.btn_delete);

        image.setImageDrawable(listImageInfo.get(position).getImage());

        tvName.setText("Name: " + listImageInfo.get(position).getImage_name());
        tvTime.setText("Date: " + listImageInfo.get(position).getDate_created());

        btnDelete.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                final int position = listView.getPositionForView((View) v.getParent());
                positionOgBtnToDelete = position;
                Log.v("delete btn clicked", "delete btn no: " + position);
                Toast.makeText(HomeActivity.this, "Btn delete position: " + position, Toast.LENGTH_LONG).show();
                showAlertToConfirmDelete();
            }
        });
        return vi;
    }
}

现在我的名单只包含5-6的图像。但我发现了就行错误OutOfMemory错误

Now my list only contains 5-6 images. But I'm getting error OutOfMemory error on line

return Drawable.createFromStream(((java.io.InputStream) new java.net.URL(imageInfoObj.getImageUrl()).getContent()), "src_name");

而不是这个，我展示的另一项活动，在那里我做同样的过程相同的列表。

Instead of this, I'm showing the same list on another activity, where I'm doing the same process.

另外还有两个活动的地方
 1.我用相机捕捉的意图和图像上传到服务器（调用API和使用HTTP多部分实体）
和2。我是从画廊上传图片。

Also there are other two activities where 1. I capture image using camera intent and upload to server(calling api and using Http Multipart Entity), and 2. I upload images from gallery.

这是不是我得到这个错误的唯一的地方，其实有很多在其他地方。但是，90％的错误出现在这条线。

This is not the only place I'm getting this error, in fact a lot at other places. But 90% error comes on this line.

我想知道，这个问题是否由于走在一起更多的内存所有图像的一个大尺寸的图像的到来。而如何去除呢？

I want to know, whether the problem is coming because of a single large size image of all images together taking more memory. And how to remove it?

推荐答案

使用一个图像加载器
你可以找到一个例子 rel=\"nofollow\">

Use a Image loader You can find an example here
