java - 带有多个附件的 Android 电子邮件 Intent

Question

我正在开发一个应用程序，用户可以在其中填写成绩单并通过选择的电子邮件客户端(在我的例子中为 Gmail)发送。除了文本之外，用户还需要能够附加一张或多张图像，但我似乎无法让它工作(完整的代码附在下面)。

下面是 onActivityResult，它将图像附加到 View 并将其 Uris 放入“userSelectedImageUriList”中。这似乎有效。

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(requestCode==REQUEST_CODE_BROWSE_PICTURE)
    {
        if(resultCode==RESULT_OK)
        {
            // Get return image uri. If select the image from camera the uri like file:///storage/41B7-12F1/DCIM/Camera/IMG_20180211_095139.jpg
            // If select the image from gallery the uri like content://media/external/images/media/1316970.
            Uri fileUri = data.getData();

            // Save user choose image file uri in list.
            if(userSelectedImageUriList == null)
            {
                userSelectedImageUriList = new ArrayList<Uri>();
            }
            userSelectedImageUriList.add(fileUri);

            // Create content resolver.
            ContentResolver contentResolver = getContentResolver();

            try {
                // Open the file input stream by the uri.
                InputStream inputStream = contentResolver.openInputStream(fileUri);

                // Get the bitmap.
                Bitmap imgBitmap = BitmapFactory.decodeStream(inputStream);

                ImageView imageview = new ImageView(ReportCard.this);
                LinearLayout linearLayout = (LinearLayout)findViewById(R.id.imageHolderLayout);
                LinearLayout.LayoutParams params = new LinearLayout
                        .LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);

                // Add image path from drawable folder.
                imageview.setImageBitmap(imgBitmap);
                imageview.setLayoutParams(params);
                linearLayout.addView(imageview);

                inputStream.close();
            }catch(FileNotFoundException ex)
            {
                Log.e(TAG_BROWSE_PICTURE, ex.getMessage(), ex);
            }catch(IOException ex)
            {
                Log.e(TAG_BROWSE_PICTURE, ex.getMessage(), ex);
            }
        }
    }
}

接下来，当用户单击发送按钮时，我创建电子邮件 Intent 。

public void sendReport(Context context) {
    EditText nameField = (EditText)findViewById(R.id.EditTextName);
    EditText emailField = (EditText)findViewById(R.id.EditTextEmail);
    EditText locationField = (EditText)findViewById(R.id.EditTextLocation);
    EditText dateField = (EditText)findViewById(R.id.EditTextDate);
    EditText bodyField = (EditText)findViewById(R.id.EditTextBody);

    if(!nameField.getText().toString().matches("") && !emailField.getText().toString().matches("") && !locationField.getText().toString().matches("") && !dateField.getText().toString().matches("") && !bodyField.getText().toString().matches("")) {
        PreferenceManager.getDefaultSharedPreferences(getBaseContext()).edit().putString("report_email", emailField.getText().toString()).commit();
        PreferenceManager.getDefaultSharedPreferences(getBaseContext()).edit().putString("report_name", nameField.getText().toString()).commit();

        String emailBody = "Name: "+nameField.getText()+"\n\n";
        emailBody += "Location: "+locationField.getText()+"\n\n";
        emailBody += "Time: "+dateField.getText()+"\n\n";
        emailBody += "Description: "+bodyField.getText();

        Intent emailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);

        // set the type to 'email'
        emailIntent.setType("text/plain");
        String to[] = {emailField.getText().toString()};
        emailIntent.putExtra(Intent.EXTRA_EMAIL, to);

        // the attachment
        emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, userSelectedImageUriList);

        // the mail
        emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Report");
        emailIntent.putExtra(Intent.EXTRA_TEXT, emailBody);

        startActivity(Intent.createChooser(emailIntent , "Send using..."));
        finish();
    } else {
        Toast.makeText(this, getString(R.string.field_error), Toast.LENGTH_SHORT).show();
    }
}

现在，事情到这里就停止了。显示选择器，但未附加图像。 Gmail 打开，但显示一个提示“无法附加文件”。

Answer 1

我已经解决了。选择图像后，它们将被放入 onActivityResult 中的 ArrayList“userSelectedImageUriList”中。

我只是将此列表添加到 Intent 中，而不是在 sendReport 方法中解析此列表。

工作方法如下:

public void sendReport(Context context) {
    EditText nameField = (EditText)findViewById(R.id.EditTextName);
    EditText emailField = (EditText)findViewById(R.id.EditTextEmail);
    EditText locationField = (EditText)findViewById(R.id.EditTextLocation);
    EditText dateField = (EditText)findViewById(R.id.EditTextDate);
    EditText bodyField = (EditText)findViewById(R.id.EditTextBody);

    if(!nameField.getText().toString().matches("") && !emailField.getText().toString().matches("") && !locationField.getText().toString().matches("") && !dateField.getText().toString().matches("") && !bodyField.getText().toString().matches("")) {
        PreferenceManager.getDefaultSharedPreferences(getBaseContext()).edit().putString("report_email", emailField.getText().toString()).apply();
        PreferenceManager.getDefaultSharedPreferences(getBaseContext()).edit().putString("report_name", nameField.getText().toString()).apply();

        String emailBody = "Name: "+nameField.getText()+"\n\n";
        emailBody += "Location: "+locationField.getText()+"\n\n";
        emailBody += "Time: "+dateField.getText()+"\n\n";
        emailBody += "Description: "+bodyField.getText();

        Intent emailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);

        // set the type to 'email'
        emailIntent.setType("text/plain");
        String to[] = {emailField.getText().toString()};
        emailIntent.putExtra(Intent.EXTRA_EMAIL, to);

        // the attachment - ArrayList populated in onActivityResult
        emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, userSelectedImageUriList);

        // the mail
        emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Report);
        emailIntent.putExtra(Intent.EXTRA_TEXT, emailBody);

        startActivity(Intent.createChooser(emailIntent , "Send with..."));
        //finish();
    } else {
        Toast.makeText(this, getString(R.string.field_error), Toast.LENGTH_SHORT).show();
    }
}
