Hi everybocy,
I'm starting to learn how to develop for android.
I writed an activity as follow using some samples from the web, but I
have a problem with mEmailText which is not updated after picking a
contact:
public class NoteEdit extends Activity {
private EditText mWhoText;
private EditText mPhoneNumberText;
private EditText mEmailText;
private EditText mHowMuchText;
private EditText mWhatText;
private EditText mDateText;
private EditText mCommentText;
private Long mRowId;
private PaymentDbAdapter mDbHelper;
private static final int CONTACT_PICKER_RESULT = 1001;
private static final String DEBUG_TAG = "NoteEditActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mDbHelper = new PaymentDbAdapter(this);
mDbHelper.open();
setContentView(R.layout.note_edit);
setTitle(R.string.edit_note);
mWhoText = (EditText) findViewById(R.id.who);
mPhoneNumberText = (EditText) findViewById(R.id.phoneNumber);
mEmailText = (EditText) findViewById(R.id.email);
mHowMuchText = (EditText) findViewById(R.id.howMuch);
mWhatText = (EditText) findViewById(R.id.what);
mDateText = (EditText) findViewById(R.id.date);
mCommentText = (EditText) findViewById(R.id.comment);
Button confirmButton = (Button) findViewById(R.id.confirm);
Button contactPicker = (Button)
findViewById(R.id.pickContact);
contactPicker.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
setResult(RESULT_OK);
doLaunchContactPicker(view);
}
});
mRowId = (savedInstanceState == null) ? null : (Long)
savedInstanceState.getSerializable(PaymentDbAdapter.KEY_ROWID);
if (mRowId == null) {
Bundle extras = getIntent().getExtras();
mRowId = extras != null ?
extras.getLong(PaymentDbAdapter.KEY_ROWID) : null;
}
populateFields();
confirmButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
setResult(RESULT_OK);
finish();
}
});
}
public void doLaunchContactPicker(View view) {
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,
Contacts.CONTENT_URI);
startActivityForResult(contactPickerIntent,
CONTACT_PICKER_RESULT);
}
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (resultCode == RESULT_OK) {
switch (requestCode) {
case CONTACT_PICKER_RESULT:
Cursor cursor = null;
String email = "";
String phone = "";
try {
Bundle extras = data.getExtras();
Set<String> keys = extras.keySet();
Iterator<String> iterate = keys.iterator();
while (iterate.hasNext()) {
String key = iterate.next();
Log.v(DEBUG_TAG, key + "[" + extras.get(key) +
"]");
}
Uri result = data.getData();
Log.v(DEBUG_TAG, "Got a contact result: "
+ result.toString());
// get the contact id from the Uri
String id = result.getLastPathSegment();
// query for everything email
cursor =
getContentResolver().query(Email.CONTENT_URI,
null, Email.CONTACT_ID + "=?", new
String[] { id },
null);
int emailIdx = cursor.getColumnIndex(Email.DATA);
int phoneIdx = cursor.getColumnIndex(Phone.DATA);
if (cursor.moveToFirst()) {
email = cursor.getString(emailIdx);
phone = cursor.getString(phoneIdx);
Log.v(DEBUG_TAG, "Got email: " + email);
} else {
Log.w(DEBUG_TAG, "No results");
}
} catch (Exception e) {
Log.e(DEBUG_TAG, "Failed to get email data", e);
} finally {
if (cursor != null) {
cursor.close();
}
mEmailText.setText(email);
if (email.length() == 0) {
Toast.makeText(this, "No email found for
contact.",
Toast.LENGTH_LONG).show();
}
}
break;
}
} else {
Log.w(DEBUG_TAG, "Warning: activity result not ok");
}
}
private void populateFields() {
if (mRowId != null) {
Cursor note = mDbHelper.fetchNote(mRowId);
startManagingCursor(note);
mWhoText.setText(note.getString(note.getColumnIndexOrThrow(PaymentDbAdapter.KEY_WHO)));
mPhoneNumberText.setText(note.getString(note.getColumnIndexOrThrow(PaymentDbAdapter.KEY_PHONENUMBER)));
mEmailText.setText(note.getString(note.getColumnIndexOrThrow(PaymentDbAdapter.KEY_EMAIL)));
mHowMuchText.setText(note.getString(note.getColumnIndexOrThrow(PaymentDbAdapter.KEY_HOWMUCH)));
mWhatText.setText(note.getString(note.getColumnIndexOrThrow(PaymentDbAdapter.KEY_WHAT)));
mDateText.setText(note.getString(note.getColumnIndexOrThrow(PaymentDbAdapter.KEY_DATE)));
mCommentText.setText(note.getString(note.getColumnIndexOrThrow(PaymentDbAdapter.KEY_COMMENT)));
}
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
saveState();
outState.putSerializable(PaymentDbAdapter.KEY_ROWID, mRowId);
}
@Override
protected void onPause() {
super.onPause();
saveState();
}
@Override
protected void onResume() {
super.onResume();
populateFields();
}
private void saveState() {
String who = mWhoText.getText().toString();
String phoneNumber = mPhoneNumberText.getText().toString();
String email = mEmailText.getText().toString();
String howMuch = mHowMuchText.getText().toString();
String what = mWhatText.getText().toString();
String date = mDateText.getText().toString();
String comment = mCommentText.getText().toString();
if (mRowId == null) {
long id = mDbHelper.createNote(who, phoneNumber, email,
howMuch, what, date, comment);
if (id > 0) {
mRowId = id;
}
} else {
mDbHelper.updateNote(mRowId, who, phoneNumber, email,
howMuch, what, date, comment);
}
}
}
so the line "mEmailText.setText(email);" doesn't seem to work since
the email string is not written inside the text field although the
email string is correctly find in the contact list according to log
file.
I am struggling with this for two days now, so if anybody could help
me, that would be very appreciated.
