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;
    }

}`
