现在比较流行所以就尝试写了一个demo。发现确实比较好用,
首先,导入相关的库
//rxJava
compile ‘io.reactivex:rxjava:latest.release’
compile ‘io.reactivex:rxandroid:latest.release’
//network - squareup
compile ‘com.squareup.retrofit2:retrofit:latest.release’
compile ‘com.squareup.retrofit2:adapter-rxjava:latest.release’
compile ‘com.squareup.okhttp3:okhttp:latest.release’
compile ‘com.squareup.okhttp3:logging-interceptor:latest.release’
首先获取Retrofit实例对象
Retrofit retrofit = new Retrofit.Builder() .baseUrl(“http://pic41.nipic.com“) .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.build();
----------------
在使用Retrofit的时候它的网路访问时通过注解来实现,要有一个定义访问参数和访问类型的接口
interface ServiceApi{
@GET(“/20140509/4746986_145156378323_2.jpg”)
Observable<ResponseBody>downloadPcFromNet();
其中可以定义post请求,也可以设置请求参数,相关使用百度一下
---------------
下来获取ServiceApi
ServiceApi service = retrofit.create(ServiceApi.class);
rxjava最方便的就是没有handler 没有去显示的new 子线程,没有去用异步加载。代码看起来比较整洁,下面放demo了 ,没有分包久一个类解决所有问题
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
private ImageView mImageView ;
private ProgressDialog progressBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mImageView =(ImageView)findViewById(R.id.image);
progressBar = new ProgressDialog(this);
com.example.hefei.myapplication.ViewUtils.setOnClick(this,this,R.id.text);
}
@Override
public void onClick(View v) {
Load();
}
private void Load() {
progressBar.show();
getService().downloadPicFromNet()
.subscribeOn(Schedulers.newThread())
.map(new Func1<ResponseBody, Bitmap>() {
@Override
public Bitmap call(ResponseBody responseBody) {
return BitmapFactory.decodeStream(responseBody.byteStream());
}
})
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<Bitmap>() {
@Override
public void onCompleted() {
progressBar.hide();
}
@Override
public void onError(Throwable e) {
progressBar.hide();
}
@Override
public void onNext(Bitmap bitmap) {
mImageView.setImageBitmap(bitmap);
}
});
}
interface ServiceApi{
@GET("/20140509/4746986_145156378323_2.jpg")
Observable<ResponseBody> downloadPicFromNet();
}
public ServiceApi getService(){
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("http://pic41.nipic.com")
.addCallAdapterFactory(RxJavaCallAdapterFactory.create()) //添加Rxjava
.build();
return retrofit.create(ServiceApi.class);
}
}
大家可以根据需求自己改动,良心制作,测试无残留,你值得拥有
