如何从相机意图中获取图像路径? [英] How to get image path from camera intent?

问题描述

我使用 android 2.1，我想从相机意图结果中获取真实路径.我读了 从 ACTION_IMAGE_CAPTURE Intent 获取图像路径 但是它适用于 android 2.2.

i work with android 2.1 , and i want to get real path from Camera intent result. I read Get Path of image from ACTION_IMAGE_CAPTURE Intent but it is for android 2.2.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if (requestCode == CAMERA_RESULT)
    {
        Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
        imv.setImageBitmap(thumbnail);
         Uri selectedImageUri = data.getData();
         String path = getRealPathFromURI(selectedImageUri);
    }
}

private String getRealPathFromURI(Uri contentUri)
{
    try
    {
        String[] proj = { MediaStore.Images.Media.DATA };
        Cursor cursor = managedQuery(contentUri, proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    }
    catch (Exception e)
    {
        return contentUri.getPath();
    }
}

推荐答案

上面的代码适用于某些手机，但在我的情况下不适用于三星手机，所以我为所有设备实现了通用逻辑.

Its above code works in some mobile but does not work in samsung mobile in my case so I implemented the common logic for all devices.

当我从相机捕捉照片时，我使用 Cursor 实现逻辑并迭代光标并获取从相机捕捉的最后一张照片路径.

When I capture the photo from camera so I implement a logic using Cursor and iterate the cursor and get the last photo path which is capture from camera.

Cursor cursor = getContentResolver().query(Media.EXTERNAL_CONTENT_URI, new String[]{Media.DATA, Media.DATE_ADDED, MediaStore.Images.ImageColumns.ORIENTATION}, Media.DATE_ADDED, null, "date_added ASC");
if(cursor != null && cursor.moveToFirst())
{
    do {
        uri = Uri.parse(cursor.getString(cursor.getColumnIndex(Media.DATA)));
        photoPath = uri.toString();
    }while(cursor.moveToNext());
    cursor.close();
}
