Android_retrofit上传文件(包含头像)

上传文件主要就是通过接口
1.AndroidMainfest.xml中加入权限

 <uses-permission android:name="android.permission.INTERNET"/>
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
 <uses-permission android:name="android.permission.CAMERA"/>
 <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>

添加依赖

  //fresco
    compile 'com.facebook.fresco:fresco:+'
    //支持gif
    compile 'com.facebook.fresco:animated-gif:+'
    compile 'com.squareup.okhttp3:okhttp:3.9.1'
    compile 'com.google.code.gson:gson:2.8.1'

    //retrofit
    compile 'com.squareup.retrofit2:retrofit:+'
    compile 'com.squareup.retrofit2:converter-gson:+'
    //Rxjava2
    compile 'io.reactivex.rxjava2:rxjava:+'
    compile 'io.reactivex.rxjava2:rxandroid:+'
    //让retrofit支持Rxjava2
    compile 'com.squareup.retrofit2:adapter-rxjava2:+'
    compile 'com.squareup.okhttp3:logging-interceptor:3.9.1'

1.网络请求

public class RetrofitUtils {
    //自定义路径
    public static final String BASE_URL ="http://120.27.23.105/";
    private final Retrofit mRetrofit;

    public static class SINGLE_HOLDER{
        public static final RetiofitUtils INSTANCE = new RetiofitUtils(BASE_URL);
    }

    public static RetrofitUtils getInstance(){
        return SINGLE_HOLDER.INSTANCE;
    }
r
    private RetrofitUtils(String baseUrl){
        mRetrofit = buildRetrofit();
    }
    //
    private OkHttpClient buildOkHttpClient(){
        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
        return new OkHttpClient.Builder()
                .connectTimeout(10000, TimeUnit.MILLISECONDS)
                .addInterceptor(new Intercept())//拦截器
                .addInterceptor(logging)
                .build();
    }
    //创建retrofit
    private Retrofit buildRetrofit(){
        return new Retrofit.Builder()
                .client(buildOkHttpClient())
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .build();
    }
    //泛型类
    public <T> T create(Class<T> tClass){
        return mRetrofit.create(tClass);
    }
}

路径接口

public interface RetiofitVpi {
    //查找用户信息
    @GET("user/getUserInfo")
    Observable<UserBean> userBean(@Query("uid") String uid);

 //上传文件
    @Multipart
    @POST("file/upload")
    Observable<FileBean> uploadFile(@Query("uid") String uid,
                                    @Part("file\"; filename=\"avatar.jpg") RequestBody file);                       
}

anim文件夹下的文件

<!--android<set>标签代表一系列的帧动画,可以在里面添加动画效果  -->
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="2000"
        android:fromYDelta="100%p"
        android:toYDelta="0" />

    <alpha
        android:duration="2000"
        android:fromAlpha="0.0"
        android:toAlpha="1.0" />

</set>

布局

mainActiviy,请求要替换头像的接口的用户uid

public class MainActivity extends AppCompatActivity {
    private SimpleDraweeView simple_drawee_view;

    private String path;
    private Uri uri;
    @Override

        Fresco.initialize(this);
        setContentView(R.layout.activity_main);
        //获取到头像的布局
        simple_drawee_view = (SimpleDraweeView) findViewById(R.id.simple_drawee_view);
        path = Environment.getExternalStorageDirectory() + "/head.jpg";
        //获取uid
        Observable<UserBean> userInfo = userBean("3600");
        userInfo
                //需要在io子线程联网
                .subscribeOn(Schedulers.io())
                //需要在主线程更新UI
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Consumer<UserBean>() {
                    @Override

                        uri = Uri.parse(data.getIcon());
                        simple_drawee_view.setImageURI(uri);
                    }
                }, new Consumer<Throwable>() {

                showPopwindow();
            }
        });
    }

    private Observable<UserBean> userBean(String uid) {
