android - 异常详情：java.lang.IllegalStateException: Process 3188 Exceeded cursor quota 100, will kill it with Rom MIUI

Question

我使用此代码在 Sdcard 上加载缩略图，设备运行良好，但使用设备使用 rom MIUI 则出现问题“异常详细信息：java.lang.IllegalStateException：进程 3188 超出光标配额 100，将杀死它”

请帮我修一下，谢谢。

public static Bitmap getThumbnailByPath(ContentResolver cr, String path)
        throws Exception {
    String[] projection = { MediaStore.Images.Media._ID };
    Cursor cursor = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            projection, MediaStore.Images.Media.DATA + "=?",
            new String[] { path }, null);
    if (cursor != null && cursor.moveToFirst()) {
        long id = cursor.getLong(0);
        return getThumbnailById(cr, id);
    } else
        cursor.close();
    return null;
}

public static Bitmap getThumbnailById(ContentResolver cr, long idPhoto)
        throws Exception {
    return MediaStore.Images.Thumbnails.getThumbnail(cr, idPhoto,
            MediaStore.Images.Thumbnails.MINI_KIND, options);
}

您必须始终关闭光标。

使用这样的东西：

Cursor cursor = ...;
try {
    if (cursor.moveToFirst())
        return getThumbnailById(cr, cursor.getLong(0));
    else
        return null;
} finally {
    cursor.close();
}
