Android Retrofit+Rxjava实现上传头像
首先肯定先要在Retrofit的Service里定义参数
//上传头像
@Multipart
@POST(HttpUrlUtils.UPLOADING_HEAD_URL)
Observable setHead(@Part MultipartBody.Part image, @Header("userId") int userId,
@Header("sessionId") String sessionId);
第一个参数是上传的头像,用Part注释声明 image是往后台提交的名字 userid和sessionId应该都知道.
//点击头像,进行选择更换
My_head.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
View view = LayoutInflater.from(getActivity()).inflate(R.layout.head_layout, null);
popupWindow = new PopupWindow(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setContentView(view);
popupWindow.setBackgroundDrawable(new ColorDrawable());
popupWindow.setOutsideTouchable(true);
popupWindow.setClippingEnabled(true);
popupWindow.setTouchable(true);
popupWindow.setFocusable(true);
popupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
@Override
public void onDismiss() {
popupWindow.dismiss();
}
});
Camera = (Button) view.findViewById(R.id.Camera);
Photo = (Button) view.findViewById(R.id.Photo);
cancel = (Button) view.findViewById(R.id.cancel);
//选择拍照.拍照上传头像暂时不好使
Camera.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
intent.addCategory("android.intent.category.DEFAULT");
startActivityForResult(intent, 0);
}
});
//点击相册,选择图片
Photo.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, 1);
}
});
popupWindow.showAsDropDown(v, 0, 0);
}
});
//这是上传头像的P层
headPersenter = new HeadPersenter(this);
调用相机相册肯定要执行Activity回调
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
//调用相机的回调
case 0:
Bitmap bitmap = data.getParcelableExtra("data");
FrescoUtils.setTo(headPath, MyBckground);
popupWindow.dismiss();
break;
//调用相册的回调
case 1:
//判断是不是选中图片了
if (resultCode == Activity.RESULT_OK) {
final int userId = SpUtil.getInt("userId", -1);
String sessionId = SpUtil.getString("SessionId", "");
Uri uri = data.getData();
if (uri!=null){
//用一个工具类获取图片的绝对路径,我会粘到下方
String path = ImageUtil.getPath(getActivity(), uri);
if (path!=null){
//转换为file类型
File file = new File(path);
//调用P层
headPersenter.setHead(userId, sessionId, file);
popupWindow.dismiss();
}
}
} else {
Toast.makeText(App.mContext, "取消选择", Toast.LENGTH_SHORT).show();
popupWindow.dismiss();
}
break;
}
}
P层的代码
public void setHead(int userId, String sessionId, File file){
headModel.setHead(userId, sessionId, file, new HeadCallBack() {
@Override
public void OnSetHeadSucess(HeadBean headBean) {
headView.OnSetHeadSucess(headBean);
}
@Override
public void OnSetHeadFailer(String msg) {
headView.OnSetHeadFailer(msg);
}
});
}
M层的代码
public void setHead(int userId, String sessionId, File file, final HeadCallBack headCallBack) {
Draww api = RetrofiApi.getInstance().creatApi(Draww.class);
//进行类型转换,因为在RetrofitService定义的是@Part MultipartBody.Part,所以要转成这样的格式
RequestBody requestBody = RequestBody.create(MediaType.parse("multipart/form-data"), file);
MultipartBody.Part image = MultipartBody.Part.createFormData("image", file.getName(),requestBody);
//然后再把image传过去
api.setHead( image,userId, sessionId).subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber() {
@Override
public void onCompleted() {
}
@Override
public void onError(Throwable e) {
headCallBack.OnSetHeadFailer(e.getMessage());
}
@Override
public void onNext(HeadBean headBean) {
headCallBack.OnSetHeadSucess(headBean);
}
});
}
获取图片路径的工具类,请自行拿取
//代码版,直接复制
public class ImageUtil {
public static Intent getGalleryIntent(Intent intent)
{
/**19之后的系统相册的图片都存在于MediaStore数据库中；19之前的系统相册中可能包含不存在与数据库中的图片，所以如果是19之上的系统

if (Build.VERSION.SDK_INT < 19) {
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
} else {

intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,"image/*");
}
return intent;
