Base64转图片与图片转Base64工具类

没有废话，直接上代码

public class BitmapStringUtils {    /**     * 将bitmap转换成为Base64     * @param bitmap     * @return     */    public  static String bitmaptoString(Bitmap bitmap) {        // 将Bitmap转换成字符串        String string = null;        ByteArrayOutputStream bStream = new ByteArrayOutputStream();        bitmap.compress(Bitmap.CompressFormat.JPEG, 10, bStream);        byte[] bytes = bStream.toByteArray();        string = Base64.encodeToString(bytes, Base64.DEFAULT);        return string;    }    /**     * 将Base64转换成为Bitmap     * @param string     * @return     */    public static Bitmap stringtoBitmap(String string){        //将字符串转换成Bitmap类型        Bitmap bitmap=null;        try {            byte[]bitmapArray;            bitmapArray=Base64.decode(string, Base64.DEFAULT);            bitmap= BitmapFactory.decodeByteArray(bitmapArray, 0, bitmapArray.length);        } catch (Exception e) {            e.printStackTrace();        }        return bitmap;    }}

使用方法

/*先得到bitmap对象*/Bitmap headBitmap = data.getParcelableExtra("data");RequestBody requestBody = new RequestBody(UserInfoActivity.this);                    requestBody.setHeadImg(BitmapStringUtils.bitmaptoString(headBitmap));//←就像括号里面这样用/*上传*/RequestUtils.createApi().uploadHeadImg(requestBody)                        .subscribeOn(Schedulers.io())                        .observeOn(AndroidSchedulers.mainThread())                        .subscribe(new CommonsSubscriber<Response>() {                             @Override                             protected void onSuccess(Response response) {                                    Toast.makeText(UserInfoActivity.this, response.getReturnInfo(), Toast.LENGTH_SHORT).show();                                    getUser();                                }                            });
