3 MyApplication継承Applicationの作成
public class MyApplication extends Application{
@Override
public void onCreate() {
super.onCreate();
Fresco.initialize(this);
}
}HomeAdapter
public class HomeAdapter extends RecyclerView.Adapter {
Context context;
List list;
public HomeAdapter(MainActivity context, List list) {
this.list = list;
this.context = context;
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
MyViewHolder holder = new MyViewHolder(LayoutInflater.from(
context).inflate(R.layout.item_home, parent,
false));
return holder;
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
MyViewHolder myViewHolder=(MyViewHolder) holder;
myViewHolder.tv.setText(list.get(position).getTitle());
Uri uri = Uri.parse(list.get(position).getPicUrl());
myViewHolder.sdv.setImageURI(uri);
}
@Override
public int getItemCount() {
return list.size();
}
class MyViewHolder extends RecyclerView.ViewHolder
{
TextView tv;
SimpleDraweeView sdv;
// SimpleDraweeView sdv;
public MyViewHolder(View view)
{
super(view);
tv = (TextView) view.findViewById(R.id.id_num);
sdv = view.findViewById(R.id.main_simple_drawee_view);
}
}
} 5 mainactivityで使用
public class MainActivity extends AppCompatActivity {
// TextView tv;
private RecyclerView mRecyclerView;
private List newslist;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// tv = (TextView) findViewById(R.id.tv);
mRecyclerView = (RecyclerView) findViewById(R.id.id_recyclerview);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
// mRecyclerView.setAdapter(mAdapter = new HomeAdapter());
// getNoParams();
getEr();
}
public void getNoParams() {
Retrofit retrofit = new Retrofit.Builder().baseUrl(Api.BASE_PATH).addConverterFactory(GsonConverterFactory.create()).addCallAdapterFactory(RxJavaCallAdapterFactory.create()).build();
//
//http://service.meiyinkeqiu.com/service/ads/cptj
ApiService apiService = retrofit.create(ApiService.class);
// Observable
Observable observable = apiService.getNoParams();
observable.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Observer() {
@Override
public void onCompleted() {
Toast.makeText(MainActivity.this,"onCompleted",Toast.LENGTH_LONG);
Log.d("main", "onCompleted: ");

}
@Override
public void onNext(News news) {

for (int i=0;i// tv.setText(ads.get(i).getGonggaoren());
}
}
});
}
public void getEr(){
Retrofit retrofit = new Retrofit.Builder().baseUrl(Api.GUO_NEI).addConverterFactory(GsonConverterFactory.create()).addCallAdapterFactory(RxJavaCallAdapterFactory.create()).build();
ApiService service = retrofit.create(ApiService.class);
Observable er = service.getEr();
er.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Observer() {
@Override
public void onCompleted() {

@Override
public void onError(Throwable e) {
}
@Override
public void onNext(Suppercalss suppercalss) {

// for (int i = 0; i< newslist.size(); i++){

// }
HomeAdapter homeAdapter = new HomeAdapter(MainActivity.this, newslist);

});
}
}
7.Apiクラスの作成
public class Api {
public static final String BASE_PATH="http://service.meiyinkeqiu.com";
public static final String GUO_NEI="http://api.tianapi.com";
}ApiServiceインタフェース、
public interface ApiService {
@GET("/service/ads/cptj")
Observable getNoParams();
@GET("/social/?key=ac87b4a4e634eb4a4e96fd371490a667&num=10")
Observable getEr();
}
