//注意 需要三张图片
三，创建model,view,persenter,bean,adapter,utils 包
model 层的 Mymode 的类
public class Mymode { public void getgouwuche(final Getgouwuchebean getgouwuchebean) {
getmInstance 需要全删了，重打
Util.getmInstance().getnetjson(Getnet.net).getuser()
.subscribeOn(Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Consumer() {
@Override
public void accept(Gouwuche gouwuche) throws Exception {
getgouwuchebean.getgouwuchejson(gouwuche);
}
});
}
public interface Getgouwuchebean {
void getgouwuchejson(Gouwuche gouwuche);
}
}
persenter 层的 Ipersenter 的接口
public interface Ipersenter { void onSuccess(Listdata); //是bean里面的List集合 void onFailed(String msg); void onDestory(); void getCarInfo(String uid); }
persenter 层的 Mypresenter 的类
public class Mypresenter implements Ipersenter { private Context context; private Iview iview; private Mymode mymode; public Mypresenter(Context context, Iview iview) { this.context = context; this.iview = iview; mymode = new Mymode(); } public void getmv() { mymode.getgouwuche(new Mymode.Getgouwuchebean() { @Override public void getgouwuchejson(Gouwuche gouwuche) { Listdata = gouwuche.getData(); iview.setadapter(context, data); } }); } @Override public void onSuccess(List data) { if (iview != null) { iview.setadapter(context, data); } } @Override public void onFailed(String msg) { if (iview != null) { iview.onFailed(msg); } } @Override public void onDestory() { if (iview != null) { iview = null; } } @Override public void getCarInfo(String uid) { } }
view 层的 Iview 的接口
public interface Iview { void setadapter(Context context, Listdata); void onFailed(String msg); void heji(); }
bean 包下的 Gouwuche
