1. If the current time

Answer 1

    Try this if you have specific time Zone.  

              try {
            SimpleDateFormat dateFormat = new SimpleDateFormat("hh a");
            Date timeseven = dateFormat.parse("7 AM");
            Date timeTen = dateFormat.parse("10 AM");
            Date timeOne = dateFormat.parse("1 PM");
            Date timefour = dateFormat.parse("4 PM");
            Date timefive = dateFormat.parse("10 PM");
            //Get current time
            // Date CurrentTime = dateFormat.parse(dateFormat.format(new Date()));
            //Sample time 
            Date CurrentTime = dateFormat.parse("9 PM");

            if (CurrentTime.after(timeseven) && CurrentTime.before(timeTen)) {
                Toast.makeText(this, "FIRST", Toast.LENGTH_SHORT).show();
            } else if (CurrentTime.after(timeTen) && CurrentTime.before(timeOne)) {
                Toast.makeText(this, "Secound", Toast.LENGTH_SHORT).show();
            } else if (CurrentTime.after(timeOne) && CurrentTime.before(timefour)) {
                Toast.makeText(this, "THird", Toast.LENGTH_SHORT).show();
            } else if (CurrentTime.after(timefour) && CurrentTime.before(timefive)) {
                Toast.makeText(this, "Fourth", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(this, "Not found in your time zone", Toast.LENGTH_SHORT).show();
            }

        } catch (Exception e) {
            e.printStackTrace();
        }

For example if you want to compare time between 11pm to 6am for calculating extra night fare for any vechicle. then following code will help you.

// Code

package com.example.timedate;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.TimeZone;

import android.os.Bundle;
import android.app.Activity;
import android.text.format.DateFormat;
import android.text.format.Time;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

    TextView tv;
    Button bt;
    int hour,min;
    String AM_PM;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv = (TextView)findViewById(R.id.textView1);
        bt = (Button)findViewById(R.id.button1);



        final String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(Calendar.getInstance().getTime());*/

        bt.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub


                Calendar c = Calendar.getInstance();
                hour = c.get(Calendar.HOUR_OF_DAY);
                min = c.get(Calendar.MINUTE);
                int ds = c.get(Calendar.AM_PM);
                if(ds==0)
                AM_PM="am";
                else
                AM_PM="pm";

                Toast.makeText(MainActivity.this, ""+hour+":"+min+AM_PM, Toast.LENGTH_SHORT).show();
                if((hour==11&&AM_PM.matches("pm")) || (hour<7&&AM_PM.matches("am"))  || (hour==12&&AM_PM.matches("am")))
                {
                    Toast.makeText(MainActivity.this, "Time is between the range", Toast.LENGTH_SHORT).show();
                }
                else
                    Toast.makeText(MainActivity.this, "Time is not between the range", Toast.LENGTH_SHORT).show();

            }
        });

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}`

Answer 3

if you want time between after 9PM to before 9Am you can use following condition..

if(cal.get(Calendar.HOUR_OF_DAY)> 20 || cal.get(Calendar.HOUR_OF_DAY)< 9)
{
    // do your stuffs
}

Answer 4

• Convert the two strings to Date objects (which are also time objects) Create a new Date object.
• This will contain the current time.
• Use the Date.before() and Date.after() methods to determine if you are in the time interval.

EDIT: You should be able to use this directly (and no deprecated methods)

public static final String inputFormat = "HH:mm";

private Date date;
private Date dateCompareOne;
private Date dateCompareTwo;

private String compareStringOne = "9:45";
private String compareStringTwo = "1:45";

SimpleDateFormat inputParser = new SimpleDateFormat(inputFormat, Locale.US);

private void compareDates(){
    Calendar now = Calendar.getInstance();

    int hour = now.get(Calendar.HOUR);
    int minute = now.get(Calendar.MINUTE);

    date = parseDate(hour + ":" + minute);
    dateCompareOne = parseDate(compareStringOne);
    dateCompareTwo = parseDate(compareStringTwo);

    if ( dateCompareOne.before( date ) && dateCompareTwo.after(date)) {
        //yada yada
    }
}

private Date parseDate(String date) {

    try {
        return inputParser.parse(date);
    } catch (java.text.ParseException e) {
        return new Date(0);
    }
}

Answer 5

As of now, I am thinking about the following approach:

int clTime = Integer.parseInt(time1.substring(0, 1))*60 + Integer.parseInt(time1.substring(3, 4)); 

Time now = new Time();
now.setToNow();
int nowTime = now.hour*60 + now.minute;

So, I'll need to compare just integer values clTime and nowTime.

Answer 6

SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm");

Date EndTime = dateFormat.parse("10:00");

Date CurrentTime = dateFormat.parse(dateFormat.format(new Date()));

if (CurrentTime.after(EndTime))
{
    System.out.println("timeeee end ");
}

Don't forget to surrounded with a try catch block
