如何获得在Android的拍摄图像的路径 [英] How to get path of a captured image in android

问题描述

我工作的Andr​​oid应用程序。它具有捕获的图像要在屏幕上显示的功能，我需要获得图片路径，这样我就可以发送图像到服务器。

I am working on an android application. It has a functionality that captured image should display on screen and I need to get that image path, so that I can send that image to server.

我能在屏幕上显示的图像，但无法获得绝对的图片路径。

I am able to display image on screen, but unable to get absolute image path.

我收到路径：

content://media/external/images/media/1220
content://media/external/images/media/1221

我怎样才能得到实际的图片路径？

How can I get actual image path?

下面是我的code：

mintent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
mintent.putExtra(MediaStore.EXTRA_OUTPUT,
                 MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString());
startActivityForResult(mintent, 1);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);
  if ((data != null && !data.toString().equalsIgnoreCase("Intent {  }"))
      || requestCode == 1)
    switch (requestCode) {
      case 1:
        try {
          // Uri imageFileUri = data.getData();
          // String path=getRealPathFromURI(this,imageFileUri);
          // Bitmap bitmap = (Bitmap) data.getExtras().get("data");

          String photoPath = null;
          Bitmap bitmap = (Bitmap) data.getExtras().get("data");
          Intent intent = new Intent(this, Media.class);
          intent.putExtra("BitmapImage", bitmap);

          Bundle b = mintent.getExtras();
          if (b != null && b.containsKey(MediaStore.EXTRA_OUTPUT)) { // large
            // image?
            String timeStamp = new SimpleDateFormat(
                "yyyyMMdd_HHmmss").format(new Date());
            // Shouldn't have to do this ... but
            photoPath = MediaStore.Images.Media.insertImage(
                        getContentResolver(), bitmap, "Img" + timeStamp
                        + ".jpeg", null);
          }
        }
    }
}

photoPath 值显示在上面。

我怎样才能让我的形象绝对路径，从该路径。

How can I get my absolute image path from this path.

推荐答案

这是一个工作的功能 -

This is a working function--

String selectedImagePath = getPath(selectedImageUri);

private String getPath(Uri uri) {

    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = getContentResolver().query(uri, projection, null, null,null);

    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();

    return cursor.getString(column_index);
}
