不确定如何重置暂停的秒表

Not sure how to reset my paused stopwatch

(我对编码还很陌生)好吧,我已经找到了我以前的帖子的解决方案并想出了如何显示毫秒......但是,我似乎无法让暂停的实例重置回来至 00:00:00

我已经尝试了几种方法,例如 mreset elapsedTime 和将 base 设置为 00:00:00,但似乎没有任何效果!有什么建议吗?

这是 Java 文件:

package com.jackson.eason.stopwatch;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.SystemClock;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Chronometer;
import android.widget.TextView;


public class MainActivity extends Activity {

    /** Called when the activity is first created. */

    private Button startButton;
    private Button pauseButton;
    private Button resetButton;
    private long startTime = 0L;
    private Handler myHandler = new Handler();
    long timeInMillies = 0L;
    long timeSwap = 0L;
    long finalTime = 0L;

    private TextView textTimer;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        textTimer = (TextView) findViewById(R.id.textTimer);

        startButton = (Button) findViewById(R.id.start);
        startButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                startTime = SystemClock.uptimeMillis();
                myHandler.postDelayed(updateTimerMethod, 0);

            }
        });

        pauseButton = (Button) findViewById(R.id.stop);
        pauseButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                timeSwap += timeInMillies;
                myHandler.removeCallbacks(updateTimerMethod);

            }
        });

       //Updated.... Still having errors with parenthesis
    resetButton = (Button) findViewById(R.id.reset);
    resetButton.setOnClickListener(SystemClock.setCurrentTimeMillis()
     timeInMillies = 0L);
    timeSwap = 0L;
    finalTime = 0L;




    }
    private Runnable updateTimerMethod = new Runnable() {

        public void run() {
            timeInMillies = SystemClock.uptimeMillis() - startTime;
            finalTime = timeSwap + timeInMillies;

            int seconds = (int) (finalTime / 1000);
            int minutes = seconds / 60;
            seconds = seconds % 60;
            int milliseconds = (int) (finalTime % 1000);
            textTimer.setText("" + minutes + ":"
                    + String.format("%02d", seconds) + ":"
                    + String.format("%03d", milliseconds));
            myHandler.postDelayed(this, 0);
        }

    };

}

如有任何帮助,我们将不胜感激!

在您的 resetButton 操作中尝试将所有值设置回 0

在重置按钮部分,您需要包含一个 onClick 事件并将时间交换设置为 0。像这样:

.setOnClickListener(new View.OnClickListener(){
        public void onClick(View view){
            finalTime = 0;
            timeInMillis = 0L;
            timeSwap = 0L;
