上传图片

在本activity中添加

设置图片的路径
String url= Environment.getExternalStorageDirectory().getAbsolutePath()+”/renxintong.png”;
Log.e(“图片的路径”,url);

调用这个方法
homePresenter.uploadImage(uploadUrl,url);

然后在这个persenter中添加一个方法
public void uploadImage(String url,String filePath) {
RequestParams params = new RequestParams(url);

    //params.setAsJsonContent(true);    List<KeyValue> list = new ArrayList<>();    list.add(new KeyValue("file", new File(filePath)));    //list.add(new KeyValue("parameters", json.toString()));    MultipartBody body = new MultipartBody(list, "UTF-8");    params.setMultipart(true);    params.setRequestBody(body);    x.http().post(params, new Callback.CommonCallback<String>() {        @Override        public void onSuccess(String result) {            Log.e("myMessage"," "+result);        }        @Override        public void onError(Throwable ex, boolean isOnCallback) {            Log.e("myMessage"," "+ex.getMessage());        }        @Override        public void onCancelled(CancelledException cex) {        }        @Override        public void onFinished() {        }    });
