上传头像

1. 写上传头像的一个单独的工具类

package com.example.zhangbingfan0506;

import android.graphics.Bitmap;
import android.os.Environment;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.text.Format;
import java.text.SimpleDateFormat;
import java.util.Date;

public class BitMapUtils  {
    public static File getFile(Bitmap bitmap)
    {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG,50,byteArrayOutputStream);

//        当前时间
        SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss");
        Date date = new Date(System.currentTimeMillis());

        String format1 = format.format(date);
        File file = new File(Environment.getExternalStorageDirectory(), format1 + ".jpg");

        try {
            FileOutputStream fileOutputStream = new FileOutputStream(file);
            ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(byteArrayOutputStream.toByteArray());

           int x=0;
            byte[] bytes = new byte[1024 * 100];
            while ((x=byteArrayInputStream.read(bytes))!=-1)
            {
                fileOutputStream.write(bytes,0,x);
            }
            fileOutputStream.flush();
            fileOutputStream.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return file;

    }
}

1. 下面的是在你fragment或者是Activity里面写的 可能你MVP里面在你fragment里面实现的V层方法可能吐司不出来 没找到原因 但是他走MVP了
