1.AndroidMainfest.xml中加入权限
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 create(Class tClass){
return mRetrofit.create(tClass);
}

路径接口
public interface RetiofitVpi {
//查找用户信息
@GET("user/getUserInfo")
Observable userBean(@Query("uid") String uid);
//上传文件
@Multipart
@POST("file/upload")
Observable uploadFile(@Query("uid") String uid,
@Part("file\"; filename=\"avatar.jpg") RequestBody file);
}anim文件夹下的文件
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 PopupWindow window;
private String path;
private Uri uri;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//初始化
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 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() {
@Override
public void accept(UserBean nicknameBean) throws Exception {
UserBean.DataBean data = nicknameBean.getData();
uri = Uri.parse(data.getIcon());
simple_drawee_view.setImageURI(uri);
}
}, new Consumer() {
@Override
public void accept(Throwable throwable) throws Exception {
Log.e("MainActivity",throwable.toString());
}
});
//给上传头像的控件设置点击事件
simple_drawee_view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//得到更换头像的popwindow
showPopwindow();
}
});
}
private Observable userBean(String uid) {
RetiofitVpi iRetiofitVip = RetiofitUtils.getInstance().create(RetiofitVpi.class);
return iRetiofitVip.userBean(uid);
}
