此文章使用mvp模式写的
（）里的都是类
一、有Model包里的bean包（Bean、ItemBean和SpacesItemDecoration）和utils包（MyImageLoadAsyncTask和Utils）
二、presenter包里的（BasePresenter和F1Presenter）
三、view包里的activity包（MainActivity和More）、adapter包（MyCarouselAdapter、MyAdapter、MyRecy1Adapter、MyRecy2Adapter和MyGridAdapter）
application包（MyApplication）、
adapter包（Fragment_one、Fragment_two、Fragment_three、Fragment_four）
和iview包是接口（IMVPView、MainIView和MyOnclicklistener）
一、model包里
1.Model包里的
①Bean类我就不写了，里面需要的记得序列化（Serializable）
②ItemBean 类
public class ItemBean {
private String text;
private boolean select;
public ItemBean(String text, boolean select) {
this.text = text;
this.select = select;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public boolean isSelect() {
return select;
}
public void setSelect(boolean select) {
this.select = select;
}
}
③.SpacesItemDecoration类
public class SpacesItemDecoration extends RecyclerView.ItemDecoration {
private int space;
public SpacesItemDecoration(int space) {
this.space = space;
}
@Override
public void getItemOffsets(Rect outRect, View view,
RecyclerView parent, RecyclerView.State state) {
outRect.left = space;
outRect.right = space;
outRect.bottom = space;
}
}
2.utils包里的
①MyImageLoadAsyncTask类
public class MyImageLoadAsyncTask extends AsyncTask<String,Void,Bitmap> {
public interface ImageCallBack{
void callBitmap(Bitmap bitmap);
}
//定义变量记住调用者所传递进来的回调监听对象
private ImageCallBack imageCallBack;
//构造方法
public MyImageLoadAsyncTask(ImageCallBack imageCallBack){
this.imageCallBack = imageCallBack;
}
@Override
protected void onPostExecute(Bitmap bitmap) {
super.onPostExecute(bitmap);
if (bitmap != null ){
}
}
@Override
protected Bitmap doInBackground(String... params) {
String param = params[0];
try {
URL url = new URL(param);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setReadTimeout(5000);
connection.setConnectTimeout(5000);
int responseCode = connection.getResponseCode();
if (responseCode == 200){
InputStream inputStream = connection.getInputStream();
return BitmapFactory.decodeStream(inputStream);
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
②Utils类
public class Utils {
public static <T>void getHttp(String url, final GetUtils getUtils, final Class<T> clazz){
RequestParams requestParams = new RequestParams(url);
x.http().get(requestParams, new Callback.CommonCallback<String>() {
@Override
public void onSuccess(String result) {
Gson gson = new Gson();
T t = gson.fromJson(result, clazz);
getUtils.CallBack(t);
}
@Override
public void onError(Throwable ex, boolean isOnCallback) {
}
@Override
public void onCancelled(CancelledException cex) {
}
@Override
public void onFinished() {
}
});
}
public static void setImage(String url, ImageView imageView){
DisplayImageOptions build = new DisplayImageOptions.Builder()
.showImageOnLoading(R.mipmap.ic_launcher)
.showImageOnFail(R.mipmap.ic_launcher)
.cacheOnDisk(true)
.cacheInMemory(false)
.build();
ImageLoader.getInstance().displayImage(url, imageView, build);
}
public interface GetUtils{
<T>void CallBack(T t);
}
}
二、presenter层
1.BasePresenter类
public class BasePresenter <T extends IMVPView> {
private T tbase;
public T getTbase() {
return tbase;
}
public void setTbase(T tbase) {
this.tbase = tbase;
}
}
2.F1Presenter类
public class F1Presenter extends BasePresenter<MainIView> {
public void getData() {
Utils.getHttp(url, new Utils.GetUtils() {
@Override
public <T>void CallBack(T t) {
getTbase().CallBack((Bean) t);
}
},Bean.class);
}
}
