Can anyone give me a solution please,
Thanks

you can use AlarmManager to ringing or notify user at particular time.
private AlarmManager alarmManager;
private static Intent alarmIntent;
private static PendingIntent pendingAlarmIntent;
public void setTimings(){
private Calender alarmCalender = Calendar.getInstance();
alarmCalender.setTimeInMillis(System.currentTimeMillis());
alarmCalender.set(Calendar.HOUR_OF_DAY, "hour"); // hour=07
alarmCalender.set(Calendar.MINUTE, "minute"); // minute=01
alarmCalender.set(Calendar.SECOND, "second"); // second=0
alarmCalender.set(Calendar.MILLISECOND, "millisecond");//millisecond=0
setAlarm(AlarmManager.RTC_WAKEUP, alarmCalender, AlarmManager.INTERVAL_DAY);
}
public void setAlarm(int type, Calendar calendar, long timeInMillis){
alarmIntent = new Intent(context, yourBroadcastReciever.class);
pendingAlarmIntent = PendingIntent.getBroadcast(context, Constant.ALARM_REQUEST_CODE, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(type, calendar.getTimeInMillis(), timeInMillis, pendingAlarmIntent);
}
To handle the alarm at particular time you create the Reciever
yourBroadcastReciever.class
#Override
public void onReceive(Context context, Intent intent) {
// here you handle the task when alarm ringing
}
[Note: Intent and Pending Intent is compulsory for create an Alarm]

use a broadcast receiver and set the time which you are getting.

DialogFragment does not update the Display

I am new to android development and I hope you can help me solve my problem. Any help will be appreciated. I created a dialogfragment for picking dates. I am able to select the desired dates but I am having trouble in displaying the selected dates.
Here is my DialogFragment
public class DatePickerFragment extends DialogFragment implements
DatePickerDialog.OnDateSetListener {
private Calendar mCalendar;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
mCalendar = Calendar.getInstance();
int year = mCalendar.get(Calendar.YEAR);
int monthOfYear = mCalendar.get(Calendar.MONTH);
int dayOfMonth = mCalendar.get(Calendar.DAY_OF_MONTH);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, monthOfYear, dayOfMonth);
}
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
mCalendar.set(Calendar.YEAR, year);
mCalendar.set(Calendar.MONTH, monthOfYear);
mCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
}
and I call it from my remindersFragment which extends fragment
private void registerButtonListenersAndSetDefaultText() {
mDateButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//getActivity().showDialog(DATE_PICKER_DIALOG);
android.support.v4.app.DialogFragment newFragment = new DatePickerFragment();
newFragment.show(getFragmentManager(), "datePicker");
updateDateButtonText();
}
});
updateDateButtonText();
}
and my updateButton :
private void updateDateButtonText() {
// Set the date button text based upon the value from the database
SimpleDateFormat dateFormat = new SimpleDateFormat(DATE_FORMAT);
String dateForButton = dateFormat.format(mCalendar.getTime());
mDateButton.setText(dateForButton);
}
I hope you can help me. I've been trying to figure this out for days but I had no luck. Thanks in advance.

Pass string and stringbuilder from between activities

I have two activities and I need to pass some strings and a stringbuilder from TailorThreeActivity.java to EnquireActivity.java.
After displaying the string and stringbuilder data on EnquireActivity screen, I am calling an Intent to send mail by clicking on the "Send Mail" button. The "Send Mail" button will open a mail client and will set all the string and stringbuilder data as the email message body.
I am able to display the value of stringbuilder in EnquireActivity.java, but the other strings coming from TailorThreeActivity.java are not being displayed in the activity. And although the stringbuilder is being displayed in EnquireActivity, neither the strings nor the stringbuilder are displayed in the Email msg body.

One of the main problems I see is this part of code
i1.putExtra(et_name.getText().toString(), "name");
i1.putExtra(et_adult.getText().toString(), "adults");
i1.putExtra(et_child.getText().toString(), "child");
i1.putExtra(et_email.getText().toString(), "email");
i1.putExtra(et_phone.getText().toString(), "phone");
with
getname = extras.getString("name");
getadult = extras.getString("adults");
getchild = extras.getString("child");
getmail = extras.getString("email");
getphone = extras.getString("phone");
You are not sending correclty these values because when you are using putExtra the first parameter is the key and the second is the value. That's why you are not able to retrieve them in your second activity.

Intent contains name-value pair do-correct in first activity
Intent i = new Intent();
StringBuffer sb = new StringBuffer("Hello");
i.putExtra("email", "jignesh.patel#y7mail.com");
i.putExtra("sub", sb.toString());
Send like this..
For Sending Mail Set these parameters..
String message = "Your_message"; String mail_id = "Email_id"; String
sub = "Mail Subject";
Intent mail = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:" +
mail_id));
mail.putExtra(Intent.EXTRA_SUBJECT,sub);
mail.putExtra(Intent.EXTRA_TEXT, message);
startActivity(Intent.createChooser(mail,"Mail Using"));
..it will work for you..

How to use Application class to share variables while extending Activity class

Im having problem sharing a global variable that I need to retain across multiple activities. This variable is created in TextPlay class and copied onto DailyDataEntry class. I have done some research sharing variables between two activities using Intent but Im looking to share that variable to multiple classes. I think I will have to extends Application but all my other classes are extending Activity already. How am I supposed to extend Application while extending Activity? Thanks a million

Create class that will extends to Application and use it in the following manner whenever you need it:
MyApplication myAppHelper = (MyApplication) context.getApplication();
myAppHelper.setWhatever(whatever);
Whatever whatever = myAppHelper.getWhatever();

My child Activity does not send result back to parent

I am attempting to create a ToDo list for a class that I am in, and how I have the app is that I have an EditText on top to enter an item in the TDL. and then I am using an extended tablelayout to display the items. I also have a button that calls to a second activity that then has 2 other buttons to get the time and date to (hopefully) display on the TDL item after I hit the Done button on the button (where I would like to go back to the main activity) So far I am testing this on an AVD.
So what I think my issue is that I dont think my second activity is passing back the info that I want. According to the debugger, the onActivityResults method from the first one gets called earlier than the second activity gets called.
Here is the first Activity:
package com.parrishb.todo;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.view.KeyEvent;
import android.view.View;
import android.widget.EditText;
import android.widget.Button;
public class ToDoActivity extends Activity {
SharedPreferences pref;
public final static int ACTIVITY =1;
public static Globals g;
public ToDoView tdv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_to_do);
final EditText myEditText = (EditText)findViewById(R.id.myEditText);
Button mPickDate = (Button) findViewById(R.id.pickDate);
tdv = (ToDoView)findViewById(R.id.tdv);
myEditText.setOnKeyListener(new View.OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if(event.getAction()== KeyEvent.ACTION_DOWN){
if((keyCode == KeyEvent.KEYCODE_DPAD_CENTER) || (keyCode == KeyEvent.KEYCODE_ENTER)){
tdv.addRow(ToDoActivity.this, myEditText.getText().toString());
myEditText.setText("");
return true;
}
}
return false;
}
});
// CLick listener for the date/time button
mPickDate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivityForResult(new Intent(ToDoActivity.this, DatePickerActivity.class), ACTIVITY);
}
});
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
if(resultCode== RESULT_OK && requestCode== ACTIVITY){
String append= (new StringBuilder().append(data.getStringExtra("Time"))
.append(" ").append(data.getStringExtra("Date")).toString());
tdv.editRow(ToDoActivity.this, append);
}
}
}
Here is my second activity:

}

{

new StringBuilder()
.append(pad(mhour)).append(":")
.append(pad(mminute)));
}
private static String pad(int c) {
if (c >= 10)
return String.valueOf(c);
else
return "0" + String.valueOf(c);
}
//Datepicker dialog generation
private DatePickerDialog.OnDateSetListener mDateSetListener =
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {

updateDate();
}
};

}
};

mYear, mMonth, mDay);
case TIME_DIALOG_ID:
return new TimePickerDialog(this,

}
return null;
}
}

I had scratched the second activity and brought the date and time picker into the main activity.
