I am trying to read messages from an inbox and display them in an activity. My activity contains a button and listview. When I click on the button, all messages from the inbox are displayed. But my requirement is that I need to view messages from a particular number. My application is not running when I get messages from that number when I click on the click button only specific messages (associated with a particular number) must be updated.
Here's the relevant code.
myActivity.java:
public class SecureMessagesActivity extends Activity implements OnClickListener, OnItemClickListener {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTheme( android.R.style.Theme_Light );
setContentView(R.layout.main);
this.findViewById( R.id.UpdateList ).setOnClickListener( this );
}
ArrayList<String> smsList = new ArrayList<String>();
public void onItemClick( AdapterView<?> parent, View view, int pos, long id ) {
try {
String[] splitted = smsList.get( pos ).split("
");
String sender = splitted[0];
String encryptedData = "";
for ( int i = 1; i < splitted.length; ++i ) {
encryptedData += splitted[i];
}
String data = sender + "
" + StringCryptor.decrypt( new String(SmsReceiver.PASSWORD), encryptedData );
Toast.makeText( this, data, Toast.LENGTH_SHORT ).show();
}
catch (Exception e) {
e.printStackTrace();
}
}
public void onClick( View v ) {
ContentResolver contentResolver = getContentResolver();
Cursor cursor = contentResolver.query( Uri.parse( "content://sms/inbox" ), null, null, null, null);
int indexBody = cursor.getColumnIndex( SmsReceiver.BODY );
int indexAddr = cursor.getColumnIndex( SmsReceiver.ADDRESS );
if ( indexBody < 0 || !cursor.moveToFirst() ) return;
smsList.clear();
do {
String str = "Sender: " + cursor.getString( indexAddr ) + "
" + cursor.getString( indexBody );
smsList.add( str );
}
while( cursor.moveToNext() );
ListView smsListView = (ListView) findViewById( R.id.SMSList );
smsListView.setAdapter( new ArrayAdapter<String>( this, android.R.layout.simple_list_item_1, smsList) );
smsListView.setOnItemClickListener( this );
}
}
SmsReceiver.java:
public class SmsReceiver extends BroadcastReceiver {
public static final String SMS_EXTRA_NAME = "pdus";
public static final String SMS_URI = "content://sms";
public static final String ADDRESS = "address";
public static final String PERSON = "person";
public static final String DATE = "date";
public static final String READ = "read";
public static final String STATUS = "status";
public static final String TYPE = "type";

public static final String SEEN = "seen";
public static final int MESSAGE_TYPE_INBOX = 1;
public static final int MESSAGE_TYPE_SENT = 2;
public static final int MESSAGE_IS_NOT_READ = 0;
public static final int MESSAGE_IS_READ = 1;
public static final int MESSAGE_IS_NOT_SEEN = 0;
public static final int MESSAGE_IS_SEEN = 1;
public static final byte[] PASSWORD = new byte[]{ 0x20, 0x32, 0x34, 0x47, (byte) 0x84, 0x33, 0x58 };
public void onReceive( Context context, Intent intent ) {
Bundle extras = intent.getExtras();
String messages = "";
if ( extras != null ) {
Object[] smsExtra = (Object[]) extras.get( SMS_EXTRA_NAME );
ContentResolver contentResolver = context.getContentResolver();
for ( int i = 0; i < smsExtra.length; ++i ) {
SmsMessage sms = SmsMessage.createFromPdu((byte[])smsExtra[i]);
String body = sms.getMessageBody().toString();
String address = sms.getOriginatingAddress();
messages += "SMS from " + address + " :
";
messages += body + "
";
putSmsToDatabase( contentResolver, sms );
}
// Display SMS message
Toast.makeText( context, messages, Toast.LENGTH_SHORT ).show();
}
// WARNING!!!
// If you uncomment next line then received SMS will not be put to incoming.
// Be careful!
// this.abortBroadcast();
}
private void putSmsToDatabase( ContentResolver contentResolver, SmsMessage sms ) {
ContentValues values = new ContentValues();
values.put( ADDRESS, sms.getOriginatingAddress() );
values.put( DATE, sms.getTimestampMillis() );
values.put( READ, MESSAGE_IS_NOT_READ );
values.put( STATUS, sms.getStatus() );
values.put( TYPE, MESSAGE_TYPE_INBOX );
values.put( SEEN, MESSAGE_IS_NOT_SEEN );
try {
String encryptedPassword = StringCryptor.encrypt( new String(PASSWORD), sms.getMessageBody().toString() );
values.put( BODY, encryptedPassword );
}
catch ( Exception e ) {
e.printStackTrace();
}
// Push row into the SMS table
contentResolver.insert( Uri.parse( SMS_URI ), values );
}
}
