設定介面活動：SettingActivity .java

package com.example.fujianping.httprequest01.mytimer;

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;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_timer_setting_activity);
        this.initComponents();

        this.settingCertainBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                getValues();
                Intent mainActivityIntent = new Intent();
                mainActivityIntent.putExtra("totalSeconds", totalSeconds);
                setResult(RESULT_OK, mainActivityIntent);
                finish();
            }
        });
    }

        minute = minuteEditText.getText().toString().equals("") ? 0 : Integer.parseInt(minuteEditText.getText().toString());

        //        second = Integer.parseInt(secondEditText.getText().toString());

        settingCertainBtn = (Button) findViewById(R.id.setting_certain_btn);
    }
}
 

工具類 Util.java：只有一個方法：

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;//時
        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("總時長" + hour + "時" + minute + "分" + second + "秒");
    }

//    public AlertDialog.Builder getDialog(final Context context, String title, String message) {
//        AlertDialog.Builder builder = new AlertDialog.Builder(context);
//
//        return builder;
//    }

}
