Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);photoPickerIntent.setType("image/*");startActivityForResult(photoPickerIntent, 1);上面的代码从图库中选择图像@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == 1) if (resultCode == Activity.RESULT_OK) { Uri selectedImage = data.getData(); String filePath = getPath(selectedImage); String file_extn = filePath.substring(filePath.lastIndexOf(".") + 1); image_name_tv.setText(filePath); try { if (file_extn.equals("img") || file_extn.equals("jpg") || file_extn.equals("jpeg") || file_extn.equals("gif") || file_extn.equals("png")) { //FINE } else { //NOT IN REQUIRED FORMAT } } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } }}public String getPath(Uri uri) { String[] projection = {MediaColumns.DATA}; Cursor cursor = managedQuery(uri, projection, null, null, null); column_index = cursor .getColumnIndexOrThrow(MediaColumns.DATA); cursor.moveToFirst(); imagePath = cursor.getString(column_index); return cursor.getString(column_index);}现在使用多方表格数据过帐数据HttpClient httpclient = new DefaultHttpClient();HttpPost httppost = new HttpPost("LINK TO SERVER");多部分表格数据MultipartEntity mpEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);if (filePath != null) { File file = new File(filePath); Log.d("EDIT USER PROFILE", "UPLOAD: file length = " + file.length()); Log.d("EDIT USER PROFILE", "UPLOAD: file exist = " + file.exists()); mpEntity.addPart("avatar", new FileBody(file, "application/octet"));}最后将数据发布到服务器httppost.setEntity(mpEntity);HttpResponse response = httpclient.execute(httppost);
