Hi All:
I am reading and debuging Contacts source code now. But I am
very confusing about ExportVCardActivity.java,
In ActualExportThread class, I can't see anything about the contacts'
data related to the VCardComoser object,
how do they combined the contacts' data and VCardComoser object? I
want to implement a filter that can filter
the contacts' data depend on some conditions, what should I do? Thanks
very much if someone could help me!
source code:
VCardComposer composer = null;
try {
OutputStream outputStream = null;
try {
outputStream = new
FileOutputStream(mExportingFileName);
} catch (FileNotFoundException e) {
final String errorReason =
getString(R.string.fail_reason_could_not_open_file,
mExportingFileName, e.getMessage());
shouldCallFinish = false;
mHandler.post(new
ErrorReasonDisplayer(errorReason));
return;
}
// composer = new
VCardComposer(ExportVCardActivity.this, mVCardTypeStr, true);
int vcardType = VCardConfig.VCARD_TYPE_V30_GENERIC;
composer = new VCardComposer(ExportVCardActivity.this,
vcardType, true);
composer.addHandler(composer.new
HandlerForOutputStream(outputStream));
if (!composer.init()) {
final String errorReason =
composer.getErrorReason();
Log.e(LOG_TAG, "initialization of vCard composer
failed: " + errorReason);
final String translatedErrorReason =
translateComposerError(errorReason);
mHandler.post(new ErrorReasonDisplayer(
getString(R.string.fail_reason_could_not_initialize_exporter,
translatedErrorReason)));
shouldCallFinish = false;
return;
}
int size = composer.getCount();
if (size == 0) {
mHandler.post(new ErrorReasonDisplayer(
getString(R.string.fail_reason_no_exportable_contact)));
shouldCallFinish = false;
return;
}
mProgressDialog.setProgressNumberFormat(
getString(R.string.exporting_contact_list_progress));
mProgressDialog.setMax(size);
mProgressDialog.setProgress(0);
while (!composer.isAfterLast()) {
