Android 包含多个附件的电子邮件意向
Android Email intent with multiple attachments
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（在我的例子中是 Gmail）发送。除了文本之外，用户还需要能够附加一张或多张图片，但我似乎无法让它工作（完整代码附在下方）。
下面是 onActivityResult，它将图像附加到视图并将它们的 Uris 放在 "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，我创建电子邮件意图。
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，一切都停止了。显示选择器但未附加图像。 Gmail 会打开，但会显示 "Could not attach file".

我已经解决了。选择图像后，它们将放入 onActivityResult 中的 ArrayList "userSelectedImageUriList"。
我没有在 sendReport 方法中解析此列表，而是将此列表添加到意图中。
工作方式是这样的：
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();
}
}
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（在我的例子中是 Gmail）发送。除了文本之外，用户还需要能够附加一张或多张图片，但我似乎无法让它工作（完整代码附在下方）。
下面是 onActivityResult，它将图像附加到视图并将它们的 Uris 放在 "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，我创建电子邮件意图。
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，一切都停止了。显示选择器但未附加图像。 Gmail 会打开，但会显示 "Could not attach file".

我已经解决了。选择图像后，它们将放入 onActivityResult 中的 ArrayList "userSelectedImageUriList"。
我没有在 sendReport 方法中解析此列表，而是将此列表添加到意图中。
工作方式是这样的：

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();
}
}
