copied!<p>I have completed one android application for taxi booking. In this i designed two screens. one is named as job started screen and anther one is named as job completion screen. In job started screen i have wrote two conditions using if else statement. In if condition i set minimum fare as 100 for 4 kilometers. if toatalkm goes above minDist means i go for else condition and here i make some calculations for every km add 10 rupee with that minimum fare and for waiting time. like below i shown.</p> <pre><code> if (totalKm<Contsants.minDist) { jcWaitingFare.setText("0"); float totalfare=Contsants.minFare; jcTotalFare.setText(String.format("%.2f",(totalfare))); Contsants.jobTotalKm= totalKm; Contsants.jobTotalFare=totalfare; } else { jcWaitingFare.setText(Integer.toString((Contsants.cont_WaitingTimeInSec/60)*1)); float totalfare= Contsants.minFare+ ((totalKm-Contsants.minDist) *Contsants.rupeeKm) +(Contsants.cont_WaitingTimeInSec/60)*1; jcTotalFare.setText(String.format("%.2f",(totalfare))); Contsants.jobTotalKm= totalKm; Contsants.jobTotalFare=totalfare; } </code></pre> <p>I want to display the current fare details into the job completed screen. I dont know how to get the current fare details from the above statement and set it to the job completion activity. today only tested my app. then only i came to know that application hangs up on the job started screen. </p> <p>below is my screen. here the calculation is not displayed properly. when click on the finish button it moves to job completed activity. in this activity we designed to see the total fare and waiting time. how to get the current details from this screen and set it to the job completed screen.</p> <p><img src="https://i.stack.imgur.com/DmjMr.png" alt="enter image description here"> job completed screen class:</p> <pre><code>private TextView jcJobNo;
