android - 通过相机获取最近拍摄的图像的路径和图像名称

Question

我必须将捕获的图像上传到 ftp 服务器。我正在通过相机捕获图像，我想获取图像名称和该图像的路径。我正在使用以下代码获取图像路径:

int ACTION_TAKE_PICTURE = 1;
String selectedImagePath;
Uri mCapturedImageURI;

Button loadButton;
ImageView img;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_new_ftpsdemo);
     img = (ImageView)findViewById(R.id.image);

    ContentValues values = new ContentValues();
    values.put(MediaStore.Images.Media.TITLE, "yahoo.jpg");
    mCapturedImageURI  = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
    Intent intentPicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    intentPicture.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
    startActivityForResult(intentPicture,ACTION_TAKE_PICTURE);

}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(requestCode == ACTION_TAKE_PICTURE){
        selectedImagePath = getRealPathFromURI(mCapturedImageURI);
        Log.v("selectedImagePath", selectedImagePath);
        img.setImageBitmap( BitmapFactory.decodeFile(selectedImagePath));
    }
}


public 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();
        }
    }

但我得到的图像路径是这样的:

/mnt/sdcard/DCIM/Camera/1352443194885.jpg

因为我正在保存名称“yahoo.jpg”。我知道这可能是一个非常简单的问题，但我无法获得相同的图像名称和路径。所以我无法将图像上传到 ftp 服务器。

检查这个...把这个放在你的 onActivityResult 中

           Uri selectedImage = intent.getData();

           String[] filePathColumn = {MediaStore.Images.Media.DATA};
           Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
           cursor.moveToFirst();
           int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
           String filePath = cursor.getString(columnIndex);
           Log.v("log","filePath is : "+filePath);
