Method to pause the countdown

Question

Good evening, I did a countdown on my app with the play button so I could start the countdown.... only that I wanted to make a method of pausing time and when I clicked on the play button again it continued from where it left off... how can I do that?

follows my code below:

time class:

package com.allsport.miyonic.allsport;


import android.content.Context;
import android.os.CountDownTimer;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

import java.util.Calendar;

public class Tempo extends CountDownTimer {

    private View.OnClickListener context;
    private TextView tv;
    private long tempao;


    public Tempo(View.OnClickListener context, TextView tv, long millisInFuture, long countDownInterval) {
        super(millisInFuture, countDownInterval);

        this.context = context;
        this.tv = tv;
    }

    @Override
    public void onTick(long millisUntilFinished) {
        tempao = millisUntilFinished;
        tv.setText(getCorretcTimer(true, millisUntilFinished)+":"+getCorretcTimer(false, millisUntilFinished));
    }

    @Override
    public void onFinish() {
        tempao -= 1000;
        tv.setText(getCorretcTimer(true, tempao)+":"+getCorretcTimer(false, tempao));

        Toast.makeText((Context) context, "Fim de jogo", Toast.LENGTH_SHORT);
    }

    private String getCorretcTimer(boolean isMinute, long millisInFuture){
        String aux;
        int calen = isMinute ? Calendar.MINUTE : Calendar.SECOND;
        Calendar cc = Calendar.getInstance();
        cc.setTimeInMillis(millisInFuture);
        aux = cc.get(calen) < 10 ? "0"+cc.get(calen) : ""+cc.get(calen);
        return (aux);
    }
}

activity code:

public class SimplesHome extends AppCompatActivity {

    private ImageButton imgButton_play, imgButton_pause, imgButton_1, imgButton_2, vermlho, amarelo;
    public TextView valorOne, valorDouble, hora;
    public int contador = 0;
    public int contador1 = 0;
    private Chronometer reloginho;
    private EditText casa, fora;
    long tempoPausado = 0;
    private Tempo time;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.activity_simples);

        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

        imgButton_1 = (ImageButton) findViewById(R.id.imgButton_1);
        imgButton_2 = (ImageButton) findViewById(R.id.imgButton_2);
        vermlho = (ImageButton) findViewById(R.id.btnVermelho);
        amarelo = (ImageButton) findViewById(R.id.btnAmarelo);
        imgButton_play = (ImageButton) findViewById(R.id.imgButton_play);
        imgButton_pause = (ImageButton) findViewById(R.id.imgButton_pause);
        reloginho = (Chronometer) findViewById(R.id.chronometer);
        valorOne = (TextView) findViewById(R.id.txt_valor1);
        valorDouble = (TextView) findViewById(R.id.txt_valor2);
        casa = (EditText) findViewById(R.id.lbl_time1);
        fora = (EditText) findViewById(R.id.lbl_time2);
        hora = (TextView) findViewById(R.id.txtTempo);


        imgButton_play.setEnabled(true);
        imgButton_pause.setEnabled(false);
        imgButton_1.setEnabled(false);
        imgButton_2.setEnabled(false);

        imgButton_play.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                imgButton_play.setEnabled(false);
                imgButton_pause.setEnabled(true);
                imgButton_1.setEnabled(true);
                imgButton_2.setEnabled(true);


                time = new Tempo(this, hora, 9901*1000, 1000);
                time.start();


                Context ini = getApplication();
                CharSequence iniciar = "Partida iniciada";
                int mostrar = Toast.LENGTH_SHORT;
                Toast ir = Toast.makeText(ini, iniciar, mostrar);
                ir.show();
            }
        });

        imgButton_pause.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                imgButton_play.setEnabled(true);
                imgButton_pause.setEnabled(false);
                imgButton_1.setEnabled(false);
                imgButton_2.setEnabled(false);

                Context parar = getApplication();
                CharSequence frase = "Partida pausada";
                int rele = Toast.LENGTH_SHORT;
                Toast stop = Toast.makeText(parar, frase, rele);
                stop.show();
            }
        });
      }
   }

Thank you....

Answer 1

Just create a boolean type variable (bool) pausado, initially with value assigned as false.

Add to Button Pause, to define the variable pausado as true. Set the Button Play, to define the variable pausado as false, and in the action to decrease the value, just add a condition, to decrease only if it is not paused, example:

if(!pausado)
{
    tempo--;
}

I hope to have helped in case of errors just leave a comment.
