Android：如何从ImageView上传照片？

Question

大家好，当我点击按钮InputFilter filter = new InputFilter() { public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) { for (int i = start; i < end; i++) { if (Character.isWhitespace(source.charAt(i))) { return ""; } } return null; } }; editText.setFilters(new InputFilter[]{filter}); 时，如何将图像上传到我的webhost上的文件管理器？截至目前，我没有开始任何事情，因为我试图按照我从图库上传的方式上传它，它没有工作。你能帮帮我们吗？截至目前，我清理了我的代码，这就是它

private void selectImage（）{

    final CharSequence[] options = { "Take Photo", "Choose from Gallery",
            "Cancel" };

    AlertDialog.Builder builder = new AlertDialog.Builder(
            CustomerRegistration.this);

    builder.setTitle("Add Photo!");

    builder.setItems(options, new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int item) {

            if (options[item].equals("Take Photo"))

            {

                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

                File f = new File(android.os.Environment
                        .getExternalStorageDirectory(), "temp.jpg");

                intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));

                startActivityForResult(intent, 1);

            }

            else if (options[item].equals("Choose from Gallery"))

            {

                Intent intent = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                startActivityForResult(intent, 2);

            }

            else if (options[item].equals("Cancel")) {

            }

// *****只需调用方法selectImage（）****** img_user_photo //图片视图
