android中的图像/图片/ jpg的日期问题（DATE_TAKEN） [英] date problem (DATE_TAKEN) for images/pictures/jpg in android

问题描述

我已经在Stackoverflow链接中通过以下已回答的问题。
，其代码如下所示。

I have gonethrough the following answered question in Stackoverflow link. which has this codes as shown below.

这里我对图像的DATE_TAKEN部分感兴趣。我已经尝试过这个代码，除了日期之外它还能完美运行。它在logcat中给出了一些数字...例如：'date_taken是2007年11月26日的图像，显​​示Log.i的日期是 1196066358000 。有没有办法将其解析回实际日期格式。

Here I'm interested on the DATE_TAKEN part of the image. I have tried this code and it is working perfectly except for the date. It is giving out some numbers in the logcat... For eg: An image whose' date_taken is 26th November 2007, the date shown Log.i is "1196066358000". Is there any way to parse this back to a real date format.

String[] projection = new String[]{
            MediaStore.Images.Media._ID,
            MediaStore.Images.Media.BUCKET_DISPLAY_NAME,
            MediaStore.Images.Media.DATE_TAKEN
    };

    // Get the base URI for the People table in the Contacts content provider.
    Uri images = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

    // Make the query.
    Cursor cur = managedQuery(images,
            projection, // Which columns to return
            "",         // Which rows to return (all rows)
            null,       // Selection arguments (none)
            ""          // Ordering
            );

    Log.i("ListingImages"," query count="+cur.getCount());

    if (cur.moveToFirst()) {
        String bucket;
        String date;
        int bucketColumn = cur.getColumnIndex(
            MediaStore.Images.Media.BUCKET_DISPLAY_NAME);

        int dateColumn = cur.getColumnIndex(
            MediaStore.Images.Media.DATE_TAKEN);

        do {
            // Get the field values
            bucket = cur.getString(bucketColumn);
            date = cur.getString(dateColumn);

            // Do something with the values.
            Log.i("ListingImages", " bucket=" + bucket 
                   + "  date_taken=" + date);

推荐答案

Abat，

自从纪元以来，您所获得的价值可能是UTC毫秒。要将其转换为可读格式，请尝试以下操作：

Perhaps that value you are getting is in UTC millis since the epoch. To convert that to a readable format try the following:

    Calendar myCal;
    myCal.setTimeInMillis(milliVal);
    Date dateText = new Date(myCal.get(Calendar.YEAR)-1900,
            myCal.get(Calendar.MONTH),
            myCal.get(Calendar.DAY_OF_MONTH),
            myCal.get(Calendar.HOUR_OF_DAY),
            myCal.get(Calendar.MINUTE));
    Log.d("MyApp", "DATE: " + android.text.format.DateFormat.format("MM/dd/yyyy hh:mm", dateText));
