I am trying to simply send an email with the data from my database as text in the email.
I have searched a ton of posts, and do not want to send as an attachment, I do not want to save to external storage etc. and cannot find what I am looking for.
I would like all the rows from the database to populate, but can only manage to get a single row. Any help would be greatly appreciated.
@Override
public void onClick(DialogInterface dialogInterface, int i) {
String[] projection = {
LogEntry._ID,
LogEntry.COLUMN_LOG_DATE,
LogEntry.COLUMN_LOG_DESTINATION,
LogEntry.COLUMN_LOG_PURPOSE,
LogEntry.COLUMN_LOG_MILEAGE};
Cursor cursor = getContentResolver().query(
LogEntry.CONTENT_URI,
projection,
null,
null,
null);
//TODO ???????????? I want the cursor to continue and get all the data from the database???
//This is the current result in the email.
// 1
// 05 Mar 2018
// 12:10:52 PM
// 0
// 0
// 88031
// Extract the properties from cursor
// Find columns of log attributes that I am interested in
int idColumnIndex = cursor.getColumnIndex(LogEntry._ID);
int dateColumnIndex = cursor.getColumnIndex(LogEntry.COLUMN_LOG_DATE);
int destinationColumnIndex = cursor.getColumnIndex(LogEntry.COLUMN_LOG_DESTINATION);
int purposeColumnIndex = cursor.getColumnIndex(LogEntry.COLUMN_LOG_PURPOSE);
int mileageColumnIndex = cursor.getColumnIndex(LogEntry.COLUMN_LOG_MILEAGE);
String id = cursor.getString(idColumnIndex);
String date = cursor.getString(dateColumnIndex);
int destination = cursor.getInt(destinationColumnIndex);
int purpose = cursor.getInt(purposeColumnIndex);
String mileage = cursor.getString(mileageColumnIndex);
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("message/rfc822");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"[email protected]"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "All Logs for " + LogEntry.COLUMN_LOG_DATE);
emailIntent.putExtra(Intent.EXTRA_TEXT, id + "\n" + date + "\n" + destination + "\n" + purpose + "\n" + mileage);
startActivity(Intent.createChooser(emailIntent, "Select App"));
Thank You CommonsWare for answering this question. I indeed used the Stringbuilder and it worked flawlessly. Exactly what I wanted.
Here is the code now.
@Override
public void onClick(DialogInterface dialogInterface, int i) {
StringBuilder stringBuilder = new StringBuilder();
String[] projection = {
LogEntry._ID,
LogEntry.COLUMN_LOG_DATE,
LogEntry.COLUMN_LOG_DESTINATION,
LogEntry.COLUMN_LOG_PURPOSE,
LogEntry.COLUMN_LOG_MILEAGE};
Cursor cursor = getContentResolver().query(
LogEntry.CONTENT_URI,
projection,
null,
null,
null);
//if the cursor isn't null we will essentially iterate over rows and then columns
//to form a table of data as per database.
if (cursor != null) {
//more to the first row
cursor.moveToFirst();
//iterate over rows
for (int index = 0; index < cursor.getCount(); index++) {
//iterate over the columns
for(int j = 0; j < cursor.getColumnNames().length; j++){
//append the column value to the string builder and delimit by a pipe symbol
stringBuilder.append(cursor.getString(j) + " | ");
}
//add a new line carriage return
stringBuilder.append("\n");
//move to the next row
cursor.moveToNext();
}
//close the cursor
cursor.close();
}
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("message/rfc822");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"[email protected]"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Logs for " + ;
emailIntent.putExtra(Intent.EXTRA_TEXT, stringBuilder.toString()); //id + "\n" + date + "\n" + destination + "\n" + purpose + "\n" + mileage);
startActivity(Intent.createChooser(emailIntent, "Select App"));
