I am having trouble figuring out how to pass the image's uri as I need it to grab the file unless there is another way and I just don't see it (I am pretty new to this). I have the image selected working and setting the imageview's bitmap to the bitmap but now trying to have it be send to the server once the submit button is clicked.
I know I can do execute(uri); but how do I actually pull out the uri from the imageview?
Here is the code : )
public class wardrobe extends Activity implements OnClickListener {
// set variable for the fields
private EditText nameField, sizeField, colorField, quantityField;
private Spinner typeField, seasonField;
private ImageView imageview;
private ProgressBar progressBarField;
private TextView imageTextSelect, resImage;
private ProgressDialog progressDialog = null;
private int serverResponseCode = 0;
private Button uploadImageButton, postWardrobe;
private String upLoadServerUri = null;
private String imagepath = null;
private Bitmap bitmap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.wardrobe);
// image upload stuff
imageview = (ImageView) findViewById(R.id.user_photo);
imageTextSelect = (TextView) findViewById(R.id.imageTextSelect);
// button for upload image
uploadImageButton = (Button) findViewById(R.id.uploadImageButton);
// button for posting details
postWardrobe = (Button) findViewById(R.id.postButton);
uploadImageButton.setOnClickListener(this);
postWardrobe.setOnClickListener(this);
@Override
public void onClick(View v) {
/**
* Opens dialog picker, so the user can select image from the gallery.
* The result is returned in the method <code>onActivityResult()</code>
*/
if (v == uploadImageButton) {
// below allows you to open the phones gallery
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(intent, "Complete action using"), 1);
}
if (v == postWardrobe) {
// execute the post request
new ImageUploadTask().execute();
}
}
}
/**
* Retrives the result returned from selecting image, by invoking the method
* <code>selectImageFromGallery()</code>
*/
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK && requestCode == 1 && null != data) {
decodeUri(data.getData());
}
}
public void decodeUri(Uri uri) {
ParcelFileDescriptor parcelFD = null;
try {
parcelFD = getContentResolver().openFileDescriptor(uri, "r");
FileDescriptor imageSource = parcelFD.getFileDescriptor();
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeFileDescriptor(imageSource, null, o);
// the new size we want to scale to
final int REQUIRED_SIZE = 1024;
// Find the correct scale value. It should be the power of 2.
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp < REQUIRED_SIZE && height_tmp < REQUIRED_SIZE) {
break;
}
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
// decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
bitmap = BitmapFactory.decodeFileDescriptor(imageSource, null, o2);
imageview.setImageBitmap(bitmap);
// can take off below just shows path
imageTextSelect.setText("select : " + uri);
} catch (FileNotFoundException e) {
// handle errors
} catch (IOException e) {
// handle errors
} finally {
if (parcelFD != null)
try {
parcelFD.close();
} catch (IOException e) {
// ignored
}
}
}
