对于可能发布与许多其他问题类似的问题，我感到很抱歉，但我找不到解决方案或找到与发生此错误的情况类似的情况。我整个星期都在谷歌搜索和搜索，试图找到这个问题的答案，但到目前为止还没有运气。我对android还很陌生，所以如果很明显，这可能就是原因！

这些是导致错误的步骤：

该应用程序使用相机拍照
然后将此图像存储在 SDCard 上的文件夹
中制作此文件的副本并压缩到每张图像 50-100kb（这是我要显示的内容）
然后存储加载活动（onResume 我这样做）时， sqlite 数据库中图像的初始大小和文件名
如果数据库中有任何文件名，它会获取文件名并显示图像 - 这就是错误所在.

if(c.getCount() > 0) {

   String[] cols = new String[] {DBAdapter.FILENAME,DBAdapter.DATETIME};

    int[] values = new int[] {R.id.thumbnail,R.id.datetime_stamp};

    SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this, R.layout.image_listview, c, cols, values, 0);

    ListView listView = (ListView) findViewById(android.R.id.list);
    listView.setAdapter(cursorAdapter);
    listView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> listView, View view, int position, long id) {
            String row = c.getString(c.getColumnIndexOrThrow(DBAdapter.KEY_ID)); // row ID from transactions
            Toast.makeText(getBaseContext(), row, Toast.LENGTH_SHORT).show();
        }
    });
}

我显然错过了一些东西，但这只是让我发疯！

如果有任何帮助，我得到的错误是：

首先：不要将图片保存在数据库中。将其保存到 sd 并在数据库（文件路径）中放置一个引用。数据库不是为大二进制数据而设计的（可能会大大减慢它们的速度）。

其次，我认为错误不在您提供的报价片段中。如果您从相机拍照，我假设它至少为 5MP，您必须注意不要将整张图片加载为位图，因为 5MP 图片@24bit 至少需要 114 MB 内存，但是您只有大约 24 个。您要做的是将缩小的版本加载到您的 UI 中。您首先通过以下方式获得维度：

// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeResource(res, resId, options);

然后你检查你必须缩小多少（应该是 2 的幂）并使用正确的采样选项对其进行解码

 // Calculate inSampleSize
options.inSampleSize = 8;

// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeResource(res, resId, options);
