Question

我正在使用Json（解码）从网址获取信息和图片，并使用CustomListviewAdapter显示它们，但我有一个难以理解的问题，我无法找到解决方案。我没有收到任何错误（我的模拟器和手机），但有些手机正在提供bitmap size exceeds 32 bits error。我必须解决这个问题，因为我的应用程序是在谷歌游戏市场。

顺便说一句，我正在使用urlimageviewhelper库来显示来自url的图像并使用延迟加载。希望您能够帮助我。提前谢谢。

以下是代码

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);
        try {

            JSONArray jsonResponse = new JSONArray(result);
            asd = new String[3][jsonResponse.length()];
            rowItems = new ArrayList<RowItem>();

            for (int i = 0; i < jsonResponse.length(); i++) {
                JSONObject js = jsonResponse.getJSONObject(i);
                asd[0][i] = js.getString("Category_Name");
                asd[2][i] = js.getString("Image");
                asd[1][i] = js.getString("Term_ID");

                RowItem item = new RowItem(asd[2][i], asd[0][i], asd[1][i]);
                rowItems.add(item);
            }


            adapter = new CustomListViewAdapter(MainActivity.this,
                    R.layout.list_item, rowItems);

            listView.setAdapter(adapter);



        } catch (JSONException e) {
            e.printStackTrace();
        }

    }

}

RowItem类

public class RowItem<T> {
private String imageId;
private String title;
private String desc;

public RowItem(String imageId, String title, String desc) {
    this.imageId = imageId;
    this.title = title;
    this.desc = desc;
}
public String getImageId() {
    return imageId;
}
public void setImageId(String imageId) {
    this.imageId = imageId;
}
public String getDesc() {
    return desc;
}
public void setDesc(String desc) {
    this.desc = desc;
}
public String getTitle() {
    return title;
}
public void setTitle(String title) {
    this.title = title;
}

@Override
public String toString() {
    return title + "\n" + desc;
}
}

CustomListViewAdapter类

  public class CustomListViewAdapter extends ArrayAdapter<RowItem> {
Context context;
Boolean isInternetPresent = false;
public CustomListViewAdapter(Context context, int resourceId,
        List<RowItem> items) {
    super(context, resourceId, items);
    this.context = context;
}

/* private view holder class */
private class ViewHolder {
    ImageView imageView;
    TextView txtTitle;
    TextView txtDesc;
}

public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder = null;
    RowItem rowItem = getItem(position);

    LayoutInflater mInflater = (LayoutInflater) context
            .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.list_item, null);
        holder = new ViewHolder();
        holder.txtDesc = (TextView) convertView.findViewById(R.id.desc);
        holder.txtTitle = (TextView) convertView.findViewById(R.id.title);
        holder.imageView = (ImageView) convertView.findViewById(R.id.icon);
        convertView.setTag(holder);
    } else
        holder = (ViewHolder) convertView.getTag();

    holder.txtTitle.setText(rowItem.getTitle());

    ImageView img = (ImageView) convertView.findViewById(R.id.icon);
    ImageView gif = (ImageView) convertView.findViewById(R.id.icon);

    Ion.with(gif).load("http://www.example.com/wp-content/uploads/2014/03/android-icon/loading.gif");
    Drawable drawable=gif.getDrawable();
    UrlImageViewHelper.setUrlDrawable(img, rowItem.getImageId(),drawable,
            600000);
    return convertView;
}
}

try this :

String imageUrl ="http://www.example.com/wp-content/uploads/2014/03/android- icon/loading.gif"; 
public static int calculateSampleSize(BitmapFactory.Options options,
    int reqWidth, int reqHeight) {
    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {

        // Calculate ratios of height and width to requested height and
        // width
        final int heightRatio = Math.round((float) height
                / (float) reqHeight);
        final int widthRatio = Math.round((float) width / (float) reqWidth);

        // Choose the smallest ratio as inSampleSize value, this will
        // guarantee
        // a final image with both dimensions larger than or equal to the
        // requested height and width.
        inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
    }

    return inSampleSize;
}





      InputStream in1 = convertURLtoInputStream(ImageUrl);
  InputStream in2 =      convertURLtoInputStream(ImageUrl);


      final BitmapFactory.Options options = new BitmapFactory.Options();
      options.inJustDecodeBounds = true;

      BitmapFactory.decodeStream(in1, null, options); 
      options.inSampleSize = calculateSampleSize(options, imgWidth , imgHeight);


     options.inJustDecodeBounds = false;
     bitmap =  BitmapFactory.decodeStream(in2, null, options);
                        bitmapList.add(bitmap);

并非除了一些Android设备以外，位图大小超过32位错误
