安卓开发实现双方比赛计时器

安卓开发，实现双方比赛计时器：

效果图：

TimerMainActivity.java

}

线程类：MyThread.java

package com.example.fujianping.httprequest01.mytimer;import android.os.Handler;
import android.util.Log;
import android.widget.ProgressBar;
import android.widget.TextView;import com.example.fujianping.httprequest01.R;/*** Created by Administrator on 2018/12/22.*/public class MyThread implements Runnable {private final static String TAG = "MyThreadTest01";private Handler handler = new Handler();private long seconds = 1800;private TextView textView;private ProgressBar progressBar;public MyThread(TextView textView, ProgressBar progressBar) {this.textView = textView;this.progressBar = progressBar;}public void setSeconds(long seconds) {this.seconds = seconds;this.progressBar.setMax((int) seconds + 1);Log.d(TAG, "setSeconds(): progressBar.getMax() = " + progressBar.getMax());}@Overridepublic void run() {this.setTimeText(seconds--);

//        public long getTimerTextValue();
//    }
}

设置界面活动：SettingActivity .java

package com.example.fujianping.httprequest01.mytimer;import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;import com.example.fujianping.httprequest01.R;public class SettingActivity extends Activity {private final static String TAG = "SettingActivity";private EditText hourEditText;private EditText minuteEditText;private EditText secondEditText;private Button settingCertainBtn;private int hour = 0;private int minute = 0;private int second = 0;private long totalSeconds;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.my_timer_setting_activity);this.initComponents();this.settingCertainBtn.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {getValues();Intent mainActivityIntent = new Intent();mainActivityIntent.putExtra("totalSeconds", totalSeconds);setResult(RESULT_OK, mainActivityIntent);finish();}});}public void getValues() {hour = hourEditText.getText().toString().equals("") ? 0 : Integer.parseInt(hourEditText.getText().toString());minute = minuteEditText.getText().toString().equals("") ? 0 : Integer.parseInt(minuteEditText.getText().toString());second = secondEditText.getText().toString().equals("") ? 0 : Integer.parseInt(secondEditText.getText().toString());//        second = Integer.parseInt(secondEditText.getText().toString());totalSeconds = hour * 3600 + minute * 60 + second;}public void initComponents() {hourEditText = (EditText) findViewById(R.id.hour_edit_text);minuteEditText = (EditText) findViewById(R.id.minute_edit_text);secondEditText = (EditText) findViewById(R.id.second_edit_text);settingCertainBtn = (Button) findViewById(R.id.setting_certain_btn);}
}

工具类 Util.java：只有一个方法：

package com.example.fujianping.httprequest01.mytimer;import android.widget.TextView;/*** Created by Administrator on 2018/12/22.*/public class Util {public static void transportTime(TextView textView, long seconds) {int hour = (int) seconds / 3600;//时int minute = (int) seconds / 60 - hour * 60;//分int second = (int) seconds % 60;//秒
//        textView.setText(String.format("%02d:%02d:%02d", hour, minute, second));textView.setText("总时长" + hour + "时" + minute + "分" + second + "秒");}//    public AlertDialog.Builder getDialog(final Context context, String title, String message) {
//        AlertDialog.Builder builder = new AlertDialog.Builder(context);
//
//        return builder;
//    }}
