开发冲刺三

今天是周一课不少，所以冲刺的少一点，今天在android上封装好了时间函数和log函数，代码量300行，因为对媒体播放的要求，今天学习了MediaPlayer的使用，但是只是一些小的test并没有和项目结合起来，重复代码行数200行

Framework.java

package com.example.framework;

import android.widget.FrameLayout;

public class Framework {
    private  volatile  static Framework mFramework;

    private Framework()
    {

    }
    public static Framework getmFramework()
    {
        if(mFramework==null)
        {
            synchronized (Framework.class)
            {
                if(mFramework==null)
                {
                    mFramework=new Framework();
                }
            }
        }
        return  mFramework;
    }
}

LogUtils.java

package com.example.framework.utils;

import android.text.TextUtils;
import android.util.Log;

import com.example.framework.BuildConfig;

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;

import java.nio.charset.Charset;
import java.text.SimpleDateFormat;
import java.util.Date;

public class LogUtils {

    private static SimpleDateFormat mSimpleDateFormat=new SimpleDateFormat("YYYY-YMM-DD HH:mm:ss");


    //LogUtils.i("")
    public static void i(String text)
    {
        if(BuildConfig.LOG_DEBUG) {
            if (!TextUtils.isEmpty(text)) {

                Log.i(BuildConfig.LOG_TAG, text);
                writeToFile(text);

            }
        }
    }

    public static void e(String text)
    {
        if(BuildConfig.LOG_DEBUG) {
            if (!TextUtils.isEmpty(text)) {

                Log.e(BuildConfig.LOG_TAG, text);
                writeToFile(text);

            }
        }
    }
    private static void writeToFile(String text)
    {
        //文件路径
        String fileName="/sdcard/Meet/Meet.log";
        //时间 内容
        String log=mSimpleDateFormat.format(new Date()) +" "+text + "
";
        //检查路径
        File fileGroup =new File("/sdcard/Meet/");
        if(!fileGroup.exists())
        {
            fileGroup.mkdirs();
        }
        //开始写入
        FileOutputStream fileOutputStream=null;
        BufferedWriter bufferedWriter=null;
        try {
            fileOutputStream=new FileOutputStream(fileName,true);
            //GBK才能正确存入中文
            bufferedWriter=new BufferedWriter(
                    new OutputStreamWriter(fileOutputStream, Charset.forName("gbk"))
            );
            try {
                bufferedWriter.write(log);
            } catch (IOException e) {
                e.printStackTrace();
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }finally {
            if(bufferedWriter!=null)
            {
                try {
                    bufferedWriter.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }

    }

}

TimeUtils.java

package com.example.framework.utils;

public class TimeUtils {
    //时间转换类
    public  static String  formatDuring(long ms)
    {
        long hours =(ms % (1000 * 60 * 60 * 24)) / (1000*60*60);
        long minutes=(ms % (1000 * 60 * 60)) / (1000*60);
        long seconds=(ms % (1000 * 60)) / (1000);

        String h=hours+"";
        if(hours<10)
        {
            h="0"+h;
        }
        String m=minutes+"";
        if(minutes<10)
        {
            m="0"+m;
        }
        String s=seconds+"";
        if(seconds<10)
        {
            s="0"+s;
        }
        return h + ":" + m + ":" + s;





    }
