需要新增的依賴 compile 'com.android.support:recyclerview-v7:25.3.1' compile 'com.liaoinstan.springview:library:1.2.6' compile 'com.squareup.okhttp3:okhttp:3.9.0' compile 'com.google.code.gson:gson:2.6.2' 主頁面
MainActivity
public class MainActivity extends AppCompatActivity implements V_mvp { private RecyclerView recyclerViewMVP中的P層; private SpringView Spr; private Myadapter myadapter; private P_mvp p_mvp; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); recyclerView = findViewById(R.id.recy); Spr= findViewById(R.id.Spr); p_mvp = new P_mvp(this); ArrayList<String> list = new ArrayList<>(); for (int i=0; i<100 ; i++){ list.add("條目"+i+""); } Spr.setHeader(new DefaultHeader(this)); Spr.setFooter(new DefaultFooter(this)); Spr.setListener(new SpringView.OnFreshListener() { @Override public void onRefresh() { //下拉重新整理 Spr.onFinishFreshAndLoad(); //listbig.addAll(0,list); myadapter.notifyDataSetChanged(); } @Override public void onLoadmore() { //上拉載入 Spr.onFinishFreshAndLoad(); //listbig.addAll(list); myadapter.notifyDataSetChanged(); } }); recyclerView.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false)); myadapter = new Myadapter(this,list); recyclerView.setAdapter(myadapter); } @Override public void cg(final Object object) { runOnUiThread(new Runnable() { @Override public void run() { Log.i("222222",object.toString()); Toast.makeText(MainActivity.this, "登入成功", Toast.LENGTH_SHORT).show(); } }); } @Override public void sb(int date) { Toast.makeText(MainActivity.this, "登入失敗", Toast.LENGTH_SHORT).show(); } }
public class P_mvp { private final V_mvp v_mvp; private final M_mvp m_mvp; public P_mvp(final V_mvp v_mvp) { this.v_mvp = v_mvp; m_mvp = new M_mvp(); m_mvp.huoqushuj(new ChengGongShiBai() { @Override public void shibai(int code) { v_mvp.sb(code); } @Override public void chenggong(Bean bean) { v_mvp.cg(bean); } }); } }
MVP中的V層實現介面
public interface V_mvp { public void cg(Object object); public void sb(int date); }
MVP中的M層okhttp的使用
public class M_mvp { public void huoqushuj(final ChengGongShiBai gongShiBai) { //http://120.27.23.105/product/searchProducts?keywords=%E7%AC%94%E8%AE%B0%E6%9C%AC&page=1&source=String OkHttpClient okHttpClient = new OkHttpClient(); RequestBody body = new FormBody.Builder().build(); final Request request = new Request.Builder().url("http://120.27.23.105/product/searchProducts?keywords=%E7%AC%94%E8%AE%B0%E6%9C%AC&page=1&source=String").build(); okHttpClient.newCall(request).enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { gongShiBai.shibai(1); } @Override public void onResponse(Call call, Response response) throws IOException { String result = response.body().string() ; //拿到bean類資料 Gson gson = new Gson(); Bean bean = gson.fromJson(result, Bean.class); String images = bean.getData().get(1).getImages(); Log.i("123123",images.toString()); gongShiBai.chenggong(bean); } }); } }介面卡Myatapter
class Myadapter extends RecyclerView.Adapter<Myadapter.ViewHolder1>{ Context context; ArrayList<String> list; public Myadapter(Context context, ArrayList<String> list) { this.context=context; this.list=list; } @Override public ViewHolder1 onCreateViewHolder(ViewGroup parent, int viewType) { View view = View.inflate(context, R.layout.adapter, null); return new ViewHolder1(view); } @Override public void onBindViewHolder(ViewHolder1 holder, int position) { holder.textView.setText(list.get(position)); } @Override public int getItemCount() { return list.size(); } class ViewHolder1 extends RecyclerView.ViewHolder{ TextView textView; public ViewHolder1(View itemView) { super(itemView); textView = itemView.findViewById(R.id.textView); } } }
ChengGongShiBai介面
public interface ChengGongShiBai { public void shibai(int code); void chenggong(Bean bean); }Bean類的封裝
