Question

我是android开发的初学者我有一个按钮，用于将图像加载到imageview，通过PHP上传到服务器，并说我想要另一个按钮和另一个图像视图，这样我就可以上传2张图像（以及它的路径）。
下面是我发送图像的代码。是否使函数的副本成为一个好主意？如果意见附带代码，我将非常感激。

这个是按钮的功能，并获取文件名及其路径

public void loadImagefromGallery(View view) {
    // Create intent to Open Image applications like Gallery, Google Photos
    Intent galleryIntent = new Intent(Intent.ACTION_PICK,
            android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    // Start the Intent
    startActivityForResult(galleryIntent, RESULT_LOAD_IMG);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    try {
        // When an Image is picked
        if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK
                && null != data) {
            // Get the Image from data

            Uri selectedImage = data.getData();
            String[] filePathColumn = {MediaStore.Images.Media.DATA};

            // Get the cursor
            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            // Move to first row
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            imgPath = cursor.getString(columnIndex);
            cursor.close();
            ImageView imgView = (ImageView) findViewById(R.id.imgView);
            // Set the Image in ImageView after decoding the String
            imgView.setImageBitmap(BitmapFactory
                    .decodeFile(imgPath));
            // Get the Image's file name
            String fileNameSegments[] = imgPath.split("/");
            fileName = fileNameSegments[fileNameSegments.length - 1];
            }
            else{
            Toast.makeText(this, "You haven't picked Image",
                    Toast.LENGTH_LONG).show();
        }
    } catch (Exception e) {
        Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
                .show();
    }
  }<br/><br/><br/>

，这是提交按钮上的上传功能。

buttonSubmit.setOnClickListener(new View.OnClickListener() {
        InputStream is = null;

        @Override
        public void onClick(View view) {

            BitmapFactory.Options options = null;
            options = new BitmapFactory.Options();
            options.inSampleSize = 3;
            bitmap = BitmapFactory.decodeFile(imgPath,
                    options);
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            // Must compress the Image to reduce image size to make upload easy
            bitmap.compress(Bitmap.CompressFormat.PNG, 50, stream);
            byte[] byte_arr = stream.toByteArray();
            // Encode Image to String
            encodedString = Base64.encodeToString(byte_arr, 0);

有什么意见吗？

Answer 1

首先是拳头。如果你有一个特定的问题（就像你标记为Android的那样），那么请问。这是一个通用的编程疑问。

第二：当然最好不要重复代码，至少在单个文件中。您可以创建一个上传到服务器并从路径中提取图像文件的功能，以便您可以单独使用。如果你是编程的新手，那么不要担心。你肯定会学到它。
