I'm making a SMS app, I have a contact list, I want to be able to tap on contact and pass that contact number into new activity so that I could send message to that contact number,
I know How can we pass Value of clicked List item to new Activity, but somehow I'm not able to use that Intent.putExtra method in my scenario.
private void getContactList() {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if ((cur != null ? cur.getCount() : 0) > 0) {
while (cur != null && cur.moveToNext()) {
String id = cur.getString(
cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME));
if (cur.getInt(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) {
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] {
id
},
null);
while (pCur.moveToNext()) {
String phoneNo = pCur.getString(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.i(TAG, "Name: " + name);
Log.i(TAG, "Phone Number: " + phoneNo);
}
pCur.close();
}
}
}
if (cur != null) {
cur.close();
}
}
You can use a Bundle to do this. You mentioned that you somehow couldn't call putExtra on your intent, make sure it isn't a typo as it is supposed to be putExtras, also make sure you are creating your intent correctly as shown below.
In the activity that will send the data:
Intent intent = new Intent(getActivity(), SecondActivity.class);
Bundle bundle = new Bundle();
bundle.putString("phoneNo", phoneNo);
intent.putExtras(bundle);
startActivity(intent);
Then on the receiving activity:
Bundle bundle = getIntent().getExtras();
String number = bundle.getString("phoneNo");
Could someone please help with the following issue?
I am in the process of creating an app where the client will sign on the device and then it will submit the form to an email address. The form works and data is being submitted correctly, but i am having trouble in getting the signature to display initially before the form is being submitted.
So here is what I have so far.
For my ExampleDBHelper.java class:
public static final String PERSON_FAULT_REPORTED = "faultreport";
public static final String PERSON_TECH_COMMENT = "techreport";
public static final String PERSON_SIGNATURE = "signature";
public static final String PERSON_JOB_NUMBER = "jobnumber";
public ExampleDBHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL(
"CREATE TABLE " + PERSON_TABLE_NAME +
"(" + PERSON_COLUMN_ID + " INTEGER PRIMARY KEY, " +
PERSON_FAULT_REPORTED + " TEXT, " +
PERSON_TECH_COMMENT + " TEXT, " +
PERSON_SIGNATURE + " BLOB, " +
PERSON_JOB_NUMBER + " INTEGER)"
);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + PERSON_TABLE_NAME);
onCreate(db);
}
public boolean insertPerson(String faultreport,
String techreport,
String signature,
int jobnumber) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(PERSON_FAULT_REPORTED, faultreport);
contentValues.put(PERSON_TECH_COMMENT, techreport);
contentValues.put(PERSON_SIGNATURE, signature);
contentValues.put(PERSON_JOB_NUMBER, jobnumber);
db.insert(PERSON_TABLE_NAME, null, contentValues);
return true;
}
public int numberOfRows() {
SQLiteDatabase db = this.getReadableDatabase();
int numRows = (int) DatabaseUtils.queryNumEntries(db, PERSON_TABLE_NAME);
return numRows;
}
public boolean updatePerson(String faultreport,
String techreport,
String signature,
int jobnumber) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(PERSON_FAULT_REPORTED, faultreport);
contentValues.put(PERSON_TECH_COMMENT, techreport);
contentValues.put(PERSON_SIGNATURE, signature);
contentValues.put(PERSON_JOB_NUMBER, jobnumber);
db.update(PERSON_TABLE_NAME, contentValues, PERSON_COLUMN_ID + " = ? ", new String[]{Integer.toString(id)});
return true;
}
public Integer deletePerson(Integer id) {
SQLiteDatabase db = this.getWritableDatabase();
return db.delete(PERSON_TABLE_NAME,
PERSON_COLUMN_ID + " = ? ",
new String[]{Integer.toString(id)});
}
public Cursor getPerson(int id) {
SQLiteDatabase db = this.getReadableDatabase();
Cursor res = db.rawQuery("SELECT * FROM " + PERSON_TABLE_NAME + " WHERE " +
PERSON_COLUMN_ID + "=?", new String[]{Integer.toString(id)});
return res;
}
public Cursor getAllPersons() {
SQLiteDatabase db = this.getReadableDatabase();
Cursor res = db.rawQuery("SELECT * FROM " + PERSON_TABLE_NAME, null);
return res;
}
Then in my MainActivity.java class:
faultReported = (EditText) findViewById(R.id.EFaultReported);
techComment = (EditText) findViewById(R.id.ETehComment);
sigImage = (ImageView) findViewById(R.id.custimagesig);
jobEditText = (EditText) findViewById(R.id.editCustComment);
SimpleDateFormat calld = new SimpleDateFormat( "yyMMddHHmm" );
jobEditText.setText( calld.format( new Date() ));
saveButton = (Button) findViewById(R.id.saveButton);
saveButton.setOnClickListener(this);
buttonLayout = (LinearLayout) findViewById(R.id.buttonLayout);
editButton = (Button) findViewById(R.id.editButton);
editButton.setOnClickListener(this);
deleteButton = (Button) findViewById(R.id.deleteButton);
deleteButton.setOnClickListener(this);
dbHelper = new ExampleDBHelper(this);
if (personID > 0) {
saveButton.setVisibility(View.GONE);
buttonLayout.setVisibility(View.VISIBLE);
Cursor rs = dbHelper.getPerson(personID);
rs.moveToFirst();
String faultrep = rs.getString(rs.getColumnIndex(ExampleDBHelper.PERSON_FAULT_REPORTED));
String techcom = rs.getString(rs.getColumnIndex(ExampleDBHelper.PERSON_TECH_COMMENT));
String custsign = rs.getString(rs.getColumnIndex(ExampleDBHelper.PERSON_SIGNATURE));
int personAge = rs.getInt(rs.getColumnIndex(ExampleDBHelper.PERSON_JOB_NUMBER));
if (!rs.isClosed()) {
rs.close();
}
faultReported.setText((CharSequence) faultrep);
faultReported.setFocusable(false);
faultReported.setClickable(false);
techComment.setText((CharSequence) techcom);
techComment.setFocusable(false);
techComment.setClickable(false);
sigImage.setImageDrawable(Drawable.createFromPath(custsign));
sigImage.setFocusable(false);
sigImage.setClickable(false);
jobEditText.setText((CharSequence) (personAge + ""));
jobEditText.setFocusable(false);
jobEditText.setClickable(false);
}
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.saveButton:
persistPerson();
return;
case R.id.editButton:
saveButton.setVisibility(View.VISIBLE);
buttonLayout.setVisibility(View.GONE);
faultReported.setEnabled(true);
faultReported.setFocusableInTouchMode(true);
faultReported.setClickable(true);
techComment.setEnabled(true);
techComment.setFocusableInTouchMode(true);
techComment.setClickable(true);
sigImage.setEnabled(true);
sigImage.setFocusableInTouchMode(true);
sigImage.setClickable(true);
jobEditText.setEnabled(true);
jobEditText.setFocusableInTouchMode(true);
jobEditText.setClickable(true);
return;
case R.id.deleteButton:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(R.string.deletePerson)
.setPositiveButton(R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dbHelper.deletePerson(personID);
Toast.makeText(getApplicationContext(), "Deleted Successfully", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getApplicationContext(), FragmentJob.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}
})
.setNegativeButton(R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
}
});
AlertDialog d = builder.create();
d.setTitle("Delete Form?");
d.show();
return;
}
}
public void persistPerson() {
if (personID > 0) {
if (dbHelper.updatePerson(personID,
faultReported.getText().toString(),
techComment.getText().toString(),
sigImage.getDrawable().toString(),
Integer.parseInt(jobEditText.getText().toString()))) {
Toast.makeText(getApplicationContext(), "Form Update Successful", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getApplicationContext(), FragmentJob.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
} else {
Toast.makeText(getApplicationContext(), "Form Update Failed", Toast.LENGTH_SHORT).show();
}
} else {
if (dbHelper.insertPerson(
faultReported.getText().toString(),
techComment.getText().toString(),
sigImage.getDrawable().toString(),
Integer.parseInt(jobEditText.getText().toString()))) {
Toast.makeText(getApplicationContext(), "Form Inserted", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "Could not Insert Form", Toast.LENGTH_SHORT).show();
}
Intent intent = new Intent(getApplicationContext(), FragmentJob.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}
}
Then finally the method for creating the signature:
b1 = (Button) findViewById(R.id.SignatureButton);
signImage = (ImageView) findViewById(R.id.custimagesig);
b1.setOnClickListener(onButtonClick);
Button.OnClickListener onButtonClick = new Button.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(CreateOrEditActivity.this, CaptureSignature.class);
startActivityForResult(i, 0);
}
};
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
if (resultCode == 1) {
Bitmap b = BitmapFactory.decodeByteArray(
data.getByteArrayExtra("byteArray"), 0,
data.getByteArrayExtra("byteArray").length);
signImage.setImageBitmap(Bitmap.createScaledBitmap(b, 625, 625, false));
}
Not sure if if the CaputureSignature.class is needed? This is only to bring up the "Sinature Pad" for the customer to sign on.
I am not sure what i am doing wrong here? Could some one please help?
Please let me know if you require more information.
Thanks Guys :-)
Actually you are trying to get String of image but you saved a byte as blob so in place of String custsign = rs.getString(rs.getColumnIndex(ExampleDBHelper.PERSON_SIGNATURE)); you should try byte[] custsign = rs.getBlob(rs.getColumnIndex(ExampleDBHelper.PERSON_SIGNATURE)); and parse byte[] in bitmap and set to imageView.
Edit
byte[] custsign = rs.getBlob(rs.getColumnIndex(ExampleDBHelper.PERSON_SIGNATURE));
if(custsign.length>0){
Bitmap bitmap = BitmapFactory.decodeByteArray(custsign, 0, custsign.length);
imageView.setImageBitmap(bitmap);
}else{
Toast.makeText(this,"Image is Not Fetching ",Toast.LENGTH_LONG).show();
}
Here is the problem...I have three different functions namely syncFirebaseContacts(); getAllContacts(); and compareContactUpdateList();. These function's execution order is very important because first function's output becomes input of another. As I have said I have placed these three function in my onCreate() method in sequence as described.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
datasource = new AdoreDataSource(this);
datasource.open();
syncFirebaseContacts();
getAllContacts();
compareContactUpdateList();
.......
But while debugging I found out that although pointer points syncFirebaseContacts() first but the code of getAllContact() is executed first and then compareContactUpdateList() is executed and after that syncFirebaseContacts() code is executed.
private void getAllContacts() {
String contactNumber;
ContentResolver cr = this.getContentResolver(); //Activity/Application android.content.Context
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cursor.moveToFirst()) {
do {
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
if (Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
while (pCur.moveToNext()) {
contactNumber = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
//All Mapping Stuff to be done here..
contactNumber = contactNumber.replaceAll("\\s+","");
contactNumber = contactNumber.trim();
lst2.add(contactNumber);
break;
}
pCur.close();
}
} while (cursor.moveToNext());
}
}
private void syncFirebaseContacts() {
Firebase userLocationRef = new Firebase(Constants.FIREBASE_URL_USERS);
userLocationRef.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for(DataSnapshot dsp : dataSnapshot.getChildren()){
datasource.createContact(String.valueOf(dsp.getKey()));
lst1.add(String.valueOf(dsp.getKey()));
Log.e("Hello", String.valueOf(dsp.getKey()));
}
}
#Override
public void onCancelled(FirebaseError firebaseError) {
Log.e("Could not process", "Sorry");
}
});
}
private void compareContactsUpdateList() {
ArrayList<String> commonOfAll = new ArrayList<String>(lst1);
commonOfAll.retainAll(lst2);
ContentResolver cr = this.getContentResolver(); //Activity/Application android.content.Context
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
final ArrayList<ContactsList> contacts = new ArrayList<ContactsList>();
//List<SyncContacts> syncContacts = datasource.getAllContacts();
if (cursor.moveToFirst()) {
do {
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
if (Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
while (pCur.moveToNext()) {
String nameOfContact = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String contactNumber = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
contactNumber = contactNumber.replaceAll("\\s+","");
contactNumber = contactNumber.trim();
Log.d("Name ", nameOfContact + contactNumber);
for(int j =0; j < commonOfAll.size(); j++){
if(contactNumber.equals(commonOfAll)){
Log.d("Name ", nameOfContact);
contacts.add(new ContactsList(contactNumber, nameOfContact, R.mipmap.ic_launcher));
}
}
break;
}
pCur.close();
}
} while (cursor.moveToNext());
}
final ContactsAdapterTwo contactsAdapterTwo = new ContactsAdapterTwo(this, contacts);
final GridView gridView = (GridView) findViewById(R.id.grid);
gridView.post(new Runnable() {
public void run() {
gridView.setAdapter(contactsAdapterTwo);
}
});
}
As my problem is that I want to compare two lists which is done in compareContactsUpdateList() by the line
ArrayList<String> commonOfAll = new ArrayList<String>(lst1);
commonOfAll.retainAll(lst2); as I found out that lst1 is always empty because syncFirebaseContacts() 's code is excuted at last
My applogies if my question length is too long or if my problem is trivial. But it is a big problem for me coz I am new to coding :-) please help me....Anyways Thanx in advance...

In SimpleCursorAdapter.java, you have a method bindView() which overrides the same method from its parent class, but you don't put any code in that method. Deleting the method should fix the error. But if you plan to override how binding works in that method, you may want to put some code in there starting with something like
super.bindView(view, context, cursor);
I want to have an option for user to upload two images and retrieve image after saved on database, i am new to android programming, I am trying this since four days, googled alot, but could not find out exact solution.

For saving image in database table you need to convert it to byte array and then you can put it in a contentValue. You can make a method for saving image as shown below-
protected long saveBitmap(SQLiteDatabase database, Bitmap bmp)
{
int size = bmp.getRowBytes() * bmp.getHeight();
ByteBuffer b = ByteBuffer.allocate(size); bmp.copyPixelsToBuffer(b);
byte[] bytes = new byte[size];
b.get(bytes, 0, bytes.length);
ContentValues cv=new ContentValues();
cv.put(CHUNK, bytes);
this.id= database.insert(TABLE, null, cv);
}
For fetching back that record you can do it like this-
byte[] bb = cursor.getBlob(cursor.getColumnIndex(/*Your column index for saving image*/));
