base64 图片互转

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; } } 12345678910111213141516171819202122232425262728293031323334

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(); } });
