Updating a listview in Fragment

Updating a listview in Fragment - android

I'm fairly new to programming for android and programming in general. I searched the web and stackoverflow for a solution, but can't seem to find one.
I have an app with different tabs handled in fragments. One of my fragments contains a listview. However, the listview won't updat or refresh. It should refresh when I get an incoming sms. Here is the fragment code:
public class SmsSectionFragment extends Fragment {
#SuppressWarnings("null")
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View listView = inflater.inflate(R.layout.fragment_section_sms, container, false);
ListView mListData = (ListView) listView.findViewById(R.id.lvData);
TextView aantalSms = (TextView) listView.findViewById(R.id.aantalSms);
ArrayList<SmsInfo> listSms = getIntent().getParcelableArrayListExtra("ListSMS");
// check condition
if(listSms != null && listSms.size() > 0) {
// set data to list
SmsInfoAdapter adapter = new SmsInfoAdapter(getActivity(), listSms);
mListData.setAdapter(adapter);
adapter.setNotifyOnChange(true);
int count = listSms.size();
aantalSms.setText(String.valueOf(count));
}
return listView;
}
The receiving of sms is handled in three other classes, the Receiver code is:
package com.example.android.effectivenavigation;
import... etc
public class SmsReceiver extends BroadcastReceiver {
static ArrayList<SmsInfo> listSms = new ArrayList<SmsInfo>();
#Override
public void onReceive(Context context, Intent intent) {
// get SMS map from intent
Bundle extras = intent.getExtras();
// a notification message
String messages = "";
if ( extras != null ) {
// get array data from SMS
Object[] smsExtra = (Object[]) extras.get( "pdus" ); // "pdus" is the key
for ( int i = 0; i < smsExtra.length; ++i ) {
// get sms message
SmsMessage sms = SmsMessage.createFromPdu((byte[])smsExtra[i]);
// get content and number
String body = sms.getMessageBody();
String adition = " SMS:: ";
String einde = " ::SMS";
String sendme = adition + body + einde;
String address = sms.getOriginatingAddress();
// create display message
messages += "SMS from " + address + " :\n";
messages += body + "\n";
//Send to Arduino
Amarino.sendDataToArduino(context, DEVICE_ADDRESS, 'T', sendme);
// store in the list
listSms.add(new SmsInfo(address, body));
}
// better check size before continue
if(listSms.size() > 0) {
// notify new arriving message
//Toast.makeText( context, messages, Toast.LENGTH_SHORT ).show();
// set data to send
Intent data = new Intent(context, MainActivity.class);
// new activity
data.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
data.putParcelableArrayListExtra("ListSMS", listSms);
// start
context.startActivity(data);
}
}
}
Could someone shine some light on my problem?
Many thanks in advance!

It looks to me like you have nothing that actually updates the fragment. Your broadcast receiver is receiving information but you never add this to the fragment.
Do something like in your fragment declaration add:
private SMSReceiver receiver;
private IntentFilter filter;
In your onCreateView add:
receiver = new SMSReceiver();
filter = new IntentFilter(SMSReceiver.YOUR_STRING_FILTER);
registerReceiver(receiver, filter);
And then in your onReceive in the SMSReceiver class add something like:
adapter = new SmsInfoAdapter (this, yourData);
list.setAdapter(adapter);
Having this all in the Fragment class is what I do.

Update ListView every second with Handler not working

In my application where the app receives a new sms message, I want the listview to update it it immediately with the new message shown in the listview. I tried using the example code of the broadcast receiver code but it didn't work, so I'm now trying to use a timer to update the listview every second and show the latest message received but this isn't working either.
final Handler handler = new Handler();
handler.postDelayed(new Runnable()
{
#Override
public void run()
{
inboxArrayAdapter.notifyDataSetChanged();
((BaseAdapter)inboxmessages.getAdapter()).notifyDataSetChanged();
handler.postDelayed(this, 1000 );
}
}, 1000);
return view;
Original attempt of using BroadcastReceiver to update listview when new SMS message recieved.
SmSBroadcastReceiver.java
public class SmsBroadcastReceiver extends BroadcastReceiver
{
public static final String SMS_BUNDLE = "pdus";
// https://javapapers.com/android/android-receive-sms-tutorial/
public void onReceive(Context context, Intent intent)
{
Bundle intentExtras = intent.getExtras();
if (intentExtras != null)
{
Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
String smsMessageStr = "";
for (int i = 0; i < sms.length; i++)
{
// Get sms message
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);
// Get content and number
String smsBody = smsMessage.getMessageBody().toString();
String address = smsMessage.getOriginatingAddress();
// Create display message
smsMessageStr += "SMS From: " + address + "\n";
smsMessageStr += smsBody + "\n";
// Add it to the list
CommandsFragment inst = CommandsFragment.instance();
inst.updateList(smsMessageStr);
}
CommandsFragment inst = CommandsFragment.instance();
inst.updateList(smsMessageStr);
}
}
}
CommandsFragment.java
public static CommandsFragment instance()
{
return inst;
}
#Override
public void onStart() {
super.onStart();
inst = this;
}
public static CommandsFragment newInstance()
{
CommandsFragment fragment = new CommandsFragment();
return fragment;
}
public void updateList(final String smsMessage)
{
inboxArrayAdapter.insert(smsMessage, 0);
inboxArrayAdapter.notifyDataSetChanged();
}

Put the listview update code inside a method in the Activity where the listview belongs, and call that method from broadcast receiver's onReceive. It would definitely work. Also check the code for whether you are updating the list view properly.
public class SmsBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context paramContext, Intent intent) { // change the parameters depending upon your requirements
// do something here with the sms received if necessary
// then call the listview update method here
}
}

Also to add to the answer don't forget to have this below in the AndroidManifest.xml file
</activity>
<receiver android:name=".SmsBroadcastReceiver">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
This above also fixed the solution for me. Thanks for your help guys.

Detect new data when call is given to webservice

I have app, in which i am refreshing that app in particular amount of time.
Each time the call is given to webservice and all the messages in database are loaded to listview.
Its done as follows:
public class Messages extends Activity {
protected Handler handler = new Handler();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_messages);
Intent intent = getIntent();
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
String id = intent.getStringExtra(MainActivity.EXTRA_ID);
String[] lst = null;
ListView lm=(ListView)findViewById(R.id.listView1);
TextView tv = (TextView)findViewById(R.id.textView1);
tv.setText("Welcome " + message);
handler.postDelayed(new UpdateTask(),750);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.messages, menu);
return true;
}
class UpdateTask implements Runnable {
#Override
public void run() {
// TODO Auto-generated method stub
setContentView(R.layout.activity_messages);
Intent intent = getIntent();
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
String id = intent.getStringExtra(MainActivity.EXTRA_ID);
String[] lst = null;
ListView lm=(ListView)findViewById(R.id.listView1);
TextView tv = (TextView)findViewById(R.id.textView1);
tv.setText("Welcome " + message);
CallSoap cs=new CallSoap();
lst=cs.GetMessage(id);
ArrayAdapter<String> adpt = new ArrayAdapter<String>(Messages.this, android.R.layout.simple_list_item_1,lst);
lm.setAdapter(adpt);
handler.postDelayed(this, 500);
}
}
}
Now, i am just unable to detect (highlight) new messages in my app, because each time when call is given to webservice it retrieves all messages.
How should i detect that this is new message(or can say as data in listview ) for this particular interval of time.
Please help me.

Add one field(i.e. Status) in database. And when you call your service and its return all message from database then status need to change with 1 (0 means still webservice not fetch, 1 means its fetch at android side). So after new records inserted your service only fetch the records which status have 0.
I hope this will help you.

Android: pass variables from Activity to BroadcastReceiver

I have some problem with passing throught my variable from Activity to the BroadcastReceiver...
Here is my code:
here is my Broadcast receiver code... I try to catch SMS from one phone number which I have got from my Activity...
public class SMSMonitor extends BroadcastReceiver
{
private static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";
public static String phone_number = "";
public static String msg_body = "";
public static final String SMS_EXTRA_NAME = "pdus";
#Override
public void onReceive(Context context, Intent intent)
{
String phone = intent.getExtras().getString("trusted_num");
if (intent != null && intent.getAction() != null && ACTION.compareToIgnoreCase(intent.getAction()) == 0)
{
Object[] pduArray = (Object[]) intent.getExtras().get("pdus");
SmsMessage[] messages = new SmsMessage[pduArray.length];
for (int i = 0; i < pduArray.length; i++)
{
messages[i] = SmsMessage.createFromPdu((byte[]) pduArray[i]);
}
phone_number = messages[0].getDisplayOriginatingAddress();
msg_body = messages[0].getMessageBody();
System.out.println("Phone number: "+phone_number);
System.out.println("Phone entered: "+phone);
}
}
}
Here is my Activity code:
public class Settings extends Activity implements OnClickListener{
private Button btn_save;
private EditText txt_phone;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
//set Save button
btn_save = (Button)findViewById(R.id.btn_save);
txt_phone = (EditText)findViewById(R.id.et_phone);
btn_save.setOnClickListener(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_settings, menu);
return true;
}
#Override
public void onClick(View v)
{
if (v == btn_save)
{
try
{
String phone_num = txt_phone.getText().toString();
Intent i = new Intent(Settings.this, SMSMonitor.class);
i.putExtra("trusted_num", phone_num);
sendBroadcast(i);
}
catch(Exception e)
{
System.out.println("Error: "+e.getLocalizedMessage());
}
}
}
}
In this code I have text field for entering the phone number, which I need to pass to the BroadcastReceiver with intent.putExtra() method, but in LogCat I see, that variable didnot pass:
07-25 18:43:57.382: I/System.out(14245): Phone number: +37129690449
07-25 18:43:57.382: I/System.out(14245): Phone entered: null
So what I am doing wrong here?
UPD
Maybe code is not correct, but it works for me...
public void onReceive(Context context, Intent intent)
{
phone = intent.getExtras().getString("trusted_num");//get trusted phone number from Settings screen
//receive SMS
if (intent != null && intent.getAction() != null && ACTION.compareToIgnoreCase(intent.getAction()) == 0)
{
Object[] pduArray = (Object[]) intent.getExtras().get("pdus");
SmsMessage[] messages = new SmsMessage[pduArray.length];
for (int i = 0; i < pduArray.length; i++)
{
messages[i] = SmsMessage.createFromPdu((byte[]) pduArray[i]);
}
phone_number = messages[0].getDisplayOriginatingAddress();
msg_body = messages[0].getMessageBody();
System.out.println("Phone number: "+phone_number);
}
//check if number is not null
if (phone != null && phone != "")
{
System.out.println("Phone entered: "+phone);
}
}
}

You can't pass an intent to a broadcast receiver. "There is no way for a BroadcastReceiver to see or capture Intents used with startActivity()"
https://developer.android.com/reference/android/content/BroadcastReceiver.html
I had a similar issue a while back and solved it by using a combination of IntentServices and Activities. You have to restructure your program to fit these guidlines

Well, there are some things not that don't match:
You're sending an intent with no action in the first place, but you're specifying Broadcastreceiver's class; don't do like that:
Intent i = new Intent(Settings.this, SMSMonitor.class);
i.putExtra("trusted_num", phone_num);
sendBroadcast(i);
But try instead:
Intent i = new Intent("my_package_name.Some_general_constant");
i.putExtra("trusted_num", phone_num);
sendBroadcast(i);
Then, your BroadcastReceiver is supposed to know that it can also handle "Some_general_constant" action. For this reason, register an extra action in your Manifest file for your SMSMonitor:
<receiver android:name=".package_to_bla_bla.SMSMonitor">
<intent-filter>
<action android:name="my_package_name.Some_general_constant"/>
</intent-filter>
</receiver>
Then in your SMSMonitor you need to add an else if statement to handle this broadcast:
else if("my_package_name.Some_general_constant".equals(intent.getAction())
{
// get the data from intent and use it
}

How to check user entered own phone number in EditText?

Mobile number will be entered in an edittext by user on registration page in my Android application. How can I check that user entered his/her mobile number not other's ?
I've tried this :
TelephonyManager tMgr =(TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
mPhoneNumber = tMgr.getLine1Number();
And compare this variable with edittext's text. But mPhoneNumber returns NULL in my case. Is there any other options? How to solve this ?
Any help would be appreciable.
I have tried this : Check source code :
public class MainActivity extends Activity{
Button submit;
EditText contact;
String phNo;

submit = (Button) findViewById(R.id.button1);
submit.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
phNo = contact.getText().toString();
new CheckOwnMobileNumber().execute();
Toast.makeText(getApplicationContext(), phNo, Toast.LENGTH_LONG).show();
}
});
}
private class CheckOwnMobileNumber extends AsyncTask<String, Void, String>

Its not guaranteed that tMgr.getLine1Number(); will always return your SIM card's number. Because it depends on the availability of number in SIM card. Like in my case, my Tre-Sweden SIM card doesn't contain my phone number.
But if you put the SIM card into an old SonyEricsson or Nokia phone, then you would get an option to edit this number (on SIM). Once its done, the android device will recognize the number and will show you.
Besides, if you do get your phone number through the code, then the best way to compare two numbers is:
boolean isSame = PhoneNumberUtils.compare(num1, num2);
Alternatively, you may implement some sort of pin-code verification logic (like Viber, WhatsApp or other application does) in which you ask the user to enter their phone number during registration. Later, that phone number is sent to the server and a pin-code is generated against that number which is sent to the user via SMS. Finally, the user has to enter that pin-code (received in SMS) to complete the registration.
Or
Simply send an SMS from user's device (with a consent) to your server/device and get to know their phone number.

Getting the phone number using getLine1Number() is not secure nor certain.
It is generally accepted because this whole "getting the phone number" is clash of multiple issues such as user's privacy, carrier's branding, and even the vendor's.
Anyway, unlike ios, android's android.provider.Telephony.SMS_RECEIVED makes the whole process very convenient and seemless to the user: You get to capture the sms and read it without any need of the user's intervention.
What is one way of doing it?
On your server, upon receiving the request to verify a phone number, you should generate a secret code, tokenSent, and send it to the app. Now, your server should send this code by sms to the specified phone number. The app by now should have a registered receiver listening for the android.provider.Telephony.SMS_RECEIVED intent. Once received, the app verifies that the tokenSent is identical to what it received from the server. At this point, phone registration is done and the server can be notified.
What could go wrong?
Generally, such apps are usually paid apps and it is not the user's good to attempt anything. Still, the user might enter a wrong number which he right now has. Then upon receiving the sms, he could forward it to the mobile where the app is registering. The app will then receive the tokenSent and wrongly verify the phone number.
How can we tackle this?
The feasibility of the solution depends on whether the sms provider allows your server to know the sender's phone number. This is probably (AFAIK) not gonna happen but if it does then you're in luck. That way, the app can, upon receiving the tokenSent, send it back to the server along with the sender of the sms. The server then can verify that this is the sms that was originated from your service provider.
Any more feasible solution? (If I am really paranoid)
In this case, the best solution, I believe, would be to request a tokenSent from your server. The server saves a generated tokenSent along with the phone number entered and sends this token to the app. The app notifies the user that registration will cost him 1 sms. Once the user accepts, you can easily send an sms in the background containing this tokenSent to a certain service. The server, once receives this tokenSent verifies the user using the token and the sender of the sms. Of course, this may seem a bit harassing and infringing to the user but it is the most secure way especially for such a paranoid (reading this part).
Formalities :P
Add Permissions in Manifest
<uses-permission android:name="android.permission.RECEIVE_SMS">
Register the receiver (Do this just before you send the sms to the phone)
registerReceiver(new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getExtras() != null)
{
Object[] pdus = (Object[]) intent.getExtras().get("pdus");
SmsMessage[] msgs = new SmsMessage[pdus.length];
for (int i=0; i<msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
String from = msgs[i].getOriginatingAddress();
String body = msgs[i].getMessageBody().toString();
//here is the body
//...
unregisterReceiver(this); //If you are done with verification

Just want to add a bit here to above explanations in the above answers. Which will save time for others as well.
In my case this method didn't returned any mobile number, an empty string was returned. It was due to the case that I had ported my number on the new sim. So if I go into the Settings>About Phone>Status>My Phone Number it shows me "Unknown".
This is probably because you have ported the number from one network to other.
If you are not able to check the number from API Then:
One way of doing that is you generate a text message to the Number and send a Random Generated no to the Mobile Number. You will have to ask the user to enter this Random generated number into your Application. Once it is entered in the application then you can send it onto the server to check whether the number passed in the text is correct or not (Which you have already saved on server against that mobile number).
I hope this makes sense.

Use clearAbortBroadcast() mehod outside onReceive in Android BroadcastReceiver

I'm developing an Android app to block incoming SMS messages and release them after do some process.
What I want to do is, When a SMS received that message need to be blocked and push it to an online server. After that an administrator can view those messages pushed to the server through a website and he/she can approve or reject. If the admin approve the message it need to be release to the phone inbox else discard the message.
I complete everything except one thing. What I did is after the message pushed to the server a scheduled timer task will be started and read the online server in every 5min and check weather the message is approved. I'm using a "BroadcastReceiver" to track incoming messages and I know that to relese a blocked message I should use "clearAbortBroadcast()" method before "onReceive" method end. BUT my timer act as a thread. So if I call "clearAbortBroadcast()" method inside the timer the "onReceive" method is already finished execution and message doesn't get released.
Can some one help me to overcome this problem.
my BroadcastReceiver class
public class SmsReceiver extends BroadcastReceiver{
// run on another Thread to avoid crash
private Handler mHandler = new Handler();
// timer handling
private Timer mTimer = null;
public static long NOTIFY_INTERVAL = 15000;
int id;
Context context;
SmsReceiver sr;
GetMsgStatus status;
Bundle bundle;
#Override
public void onReceive(Context context, Intent intent)
{
//this stops notifications to others
this.abortBroadcast();
this.context = context;
//create a instance of GetMsgStatus class
status = new GetMsgStatus(context);
//---get the SMS message passed in---
bundle = intent.getExtras();
SmsMessage[] msgs = null;
String from = null;
String to = null;
String msg= null;
String str = "";
if (bundle != null)
{
//---retrieve the SMS message received---
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i=0; i<msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
str += "SMS from " + msgs[i].getOriginatingAddress();
from = msgs[i].getOriginatingAddress();
str += " :";
str += msgs[i].getMessageBody().toString();
msg = msgs[i].getMessageBody().toString();
str += "\n";
}
System.out.println("from "+from);
System.out.println("msg "+msg);
Toast.makeText(context, "SMS Received : ",Toast.LENGTH_LONG).show();
TelephonyManager mTelephonyMgr;
mTelephonyMgr = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
to = mTelephonyMgr.getLine1Number();
//push msg to the server
SendMsgToServer send = new SendMsgToServer(context, to, from, msg);
//get the msg id of the pushed msg
id = send.getId();
// cancel if already existed
if(mTimer != null) {
mTimer.cancel();
} else {
// recreate new
mTimer = new Timer();
}
// schedule task
mTimer.scheduleAtFixedRate(new TimeDisplayTimerTask(), 0, NOTIFY_INTERVAL);
}
}
class TimeDisplayTimerTask extends TimerTask {
#Override
public void run() {
// run on another thread
mHandler.post(new Runnable() {
#Override
public void run()
{
status.getDataFromServer(id);
//if status is 0 means msg rejected
if(status.getStatus()==0)
{
mTimer.cancel();
}
//if status is 1 means msg approved
else if(status.getStatus()==1)
{
sr.clearAbortBroadcast();
mTimer.cancel();
}
//pending
else
{
System.out.println("pending");
}
}
});
}
}
}

A BroadcastReceiver is not supposed to live that much, so you can't depend on clearAbortBroadcast().
In your case I think your flow would be:
Receive broadcast and send to server.
Abort the broadcast and delete SMS from cellphone (user should be warned about this)
Wait for approval from server.
If approved, save the message to SMS and notify the user.
I don't think this kind of censor is good, but you may have your reasons, just make sure the user who install this knows what it does.
