问题:
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.
I am able to display image on screen, but unable to get absolute image path.
I am getting path like:
content://media/external/images/media/1220 content://media/external/images/media/1221
How can I get actual image path?
Here is my 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 value is shown in above.
How can I get my absolute image path from this path.
回答1:
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); }

A complete working solution
final private int PICK_IMAGE = 1; final private int CAPTURE_IMAGE = 2; private String imgPath; btnGallery.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(); intent.setType("image/*"); intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(Intent.createChooser(intent, ""), PICK_IMAGE); } }); btnCapture.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, setImageUri()); startActivityForResult(intent, CAPTURE_IMAGE); } }); public Uri setImageUri() { // Store image in dcim File file = new File(Environment.getExternalStorageDirectory() + "/DCIM/", "image" + new Date().getTime() + ".png"); Uri imgUri = Uri.fromFile(file); this.imgPath = file.getAbsolutePath(); return imgUri; } public String getImagePath() { return imgPath; } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode != Activity.RESULT_CANCELED) { if (requestCode == PICK_IMAGE) { selectedImagePath = getAbsolutePath(data.getData()); imgUser.setImageBitmap(decodeFile(selectedImagePath)); } else if (requestCode == CAPTURE_IMAGE) { selectedImagePath = getImagePath(); imgUser.setImageBitmap(decodeFile(selectedImagePath)); } else { super.onActivityResult(requestCode, resultCode, data); } } } public String getAbsolutePath(Uri uri) { String[] projection = { MediaColumns.DATA }; @SuppressWarnings("deprecation") Cursor cursor = managedQuery(uri, projection, null, null, null); if (cursor != null) { int column_index = cursor.getColumnIndexOrThrow(MediaColumns.DATA); cursor.moveToFirst(); return cursor.getString(column_index); } else return null; } public Bitmap decodeFile(String path) { try { // Decode image size BitmapFactory.Options o = new BitmapFactory.Options(); o.inJustDecodeBounds = true; BitmapFactory.decodeFile(path, o); // The new size we want to scale to final int REQUIRED_SIZE = 70; // Find the correct scale value. It should be the power of 2. int scale = 1; while (o.outWidth / scale / 2 >= REQUIRED_SIZE && o.outHeight / scale / 2 >= REQUIRED_SIZE) scale *= 2; // Decode with inSampleSize BitmapFactory.Options o2 = new BitmapFactory.Options(); o2.inSampleSize = scale; return BitmapFactory.decodeFile(path, o2); } catch (Throwable e) { e.printStackTrace(); } return null; }

on camera button
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE"); File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg"); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file)); try { intent.putExtra("return-data", true); startActivityForResult(intent, CAMERA_REQUEST); } catch (ActivityNotFoundException e) { // Do nothing for now }
and on activity result write
protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) { // Bitmap photo1 = (Bitmap) data.getExtras().get("data"); File file1 = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg"); Bitmap bitmap11 = decodeSampledBitmapFromFile(file1.getAbsolutePath(), 500, 300); // } }
