Android 显示图像位图错误

Question

您好，我正在尝试从 SD 卡中的所有文件夹中读取图像。因此，它会创建文件夹列表，例如下载、相机等。现在，当我按任何文件夹时，它会在网格视图中打开照片。我的下载文件夹包含小尺寸图像，应用程序工作正常，但是当我打开包含较大尺寸图像的相机文件夹时，我的应用程序崩溃了。我的网格视图获取功能如下。

 public View getView(int position, View convertView, ViewGroup parent) {
        ImageView i = new ImageView(mContext);  
        View v = convertView;
        if (v == null) {
            LayoutInflater vi = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = vi.inflate(R.layout.localimageview, null);
        }

        BitmapFactory.Options options=new Options();
        options.inSampleSize=2;
        options.inTempStorage = new byte[16*1024];

        Bitmap bb=BitmapFactory.decodeFile(FileList.get(position).toString(),options);
        i.setImageBitmap(bb);

        i.setLayoutParams(new GridView.LayoutParams(75,75));  
        i.setScaleType(ImageView.ScaleType.CENTER_CROP);
        i.setPadding(8, 8, 8, 8);
        v = (View)i;
        return v;  
    }
}  

它

崩溃于
位图 bb=BitmapFactory.decodeFile(FileList.get(position).toString(),options);

Answer 1

检查例如这个问题。或者搜索一下，这是以前回答过的常见问题。

Answer 2

当您访问相机图片时，一旦加载的图片太大，应用程序无法处理，您需要做的是降低图像质量并将其添加到您的活动中

Answer 3

尝试以下代码。希望有帮助

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            View row = convertView;
            ViewWrapper wrapper = null;

            try {
                if (row == null) {
                    LayoutInflater inflater = getLayoutInflater();
                    row = inflater.inflate(R.layout.gallery_template, parent,
                            false);
                    wrapper = new ViewWrapper(row);
                    row.setTag(wrapper);
                } else {
                    wrapper = (ViewWrapper) row.getTag();
                }

                Bitmap bitmap = getImage(position);

                if (bitmap != null ) {

                    wrapper.getIcon().setImageBitmap(bitmap);
                } else {
                                  showErrorDialogue(getString(R.string.noGalleryData));
                }
            } catch (Exception e) {}
            return (row);
        }

private Bitmap getImage(int position) {
        Bitmap bitmap = null;
        if (Constants.IMAGES_PATH.size() > 0) {

            try {
  BitmapFactory.Options options = new BitmapFactory.Options();
  options.inSampleSize = 4;


                String path = Constants.IMAGES_PATH.get(position);
                // -------- Decode THE BITMAP AND RESIZE IT
                bitmap = BitmapFactory
                    .decodeFile(path,options));
            } catch (Exception e) {}
        }
        return bitmap;
    }
