步骤1：在主线程中创建thread调接口

        new Thread(new Runnable() {@Overridepublic void run() {getServiceList();}}).start();

步骤2：okhttp调接口

private void getServiceList(){Message msg = new Message();try{OkHttpClient okHttpClient = new OkHttpClient();FormBody.Builder formBodyBuilder = new FormBody.Builder();formBodyBuilder.add("token", "xxx").add("id", "idxxx");if (constellationArr != null) {for (String constellation : constellationArr) {formBodyBuilder.add("constellationArr", constellation);}}FormBody formBody = formBodyBuilder.build();///Request request = new Request.Builder().url("调接口url").post(formBody).build();// 创建 Call 对象并执行请求Call call = okHttpClient.newCall(request);Response response = call.execute();// 处理响应if (response.isSuccessful()) {// 响应成功String responseBody = response.body().string();// 在这里处理响应体JSONObject jsonObject = new JSONObject(responseBody);boolean success = jsonObject.getBoolean("success");String message = jsonObject.getString("msg");String obj = jsonObject.getString("obj");Log.e(TAG, obj);if (success) {// 使用 TypeToken 获取泛型类型TypeToken<ArrayList<ServicePersonShortBean>> typeToken = new TypeToken<ArrayList<ServicePersonShortBean>>() {};ArrayList<ServicePersonShortBean> servicePersonShortBeanList = gson.fromJson(obj, typeToken.getType());Bundle bundle = new Bundle();bundle.putSerializable("servicePersonShortBeanList", servicePersonShortBeanList);msg.setData(bundle);msg.what = 1;handler.sendMessage(msg);} else {Bundle bundle = new Bundle();if(message.equals("token找不到")){bundle.putString("message", "请您登录后查询");}else{bundle.putString("message", message);}msg.setData(bundle);msg.what = 2;handler.sendMessage(msg);}} else {// 响应失败// 在这里处理失败情况msg.what = 3;handler.sendMessage(msg);}// 记得关闭响应体response.close();} catch (IOException e) {if (e.toString().contains("request failed")) {msg.what = 4;handler.sendMessage(msg);} else {msg.what = 5;handler.sendMessage(msg);}e.printStackTrace();} catch (JSONException e) {e.printStackTrace();msg.what = 3;handler.sendMessage(msg);}}

步骤三：处理返回信息，在主线程中进行UI展示

// 在主线程中创建 HandlerHandler handler = new Handler(Looper.getMainLooper()) {@Overridepublic void handleMessage(Message msg) {super.handleMessage(msg);//根据信息编码及数据做出相对应的处理switch (msg.what) {case 1:{Bundle bundle = msg.getData();servicePersonShortBeanList = (ArrayList<ServicePersonShortBean>) bundle.getSerializable("servicePersonShortBeanList");showServicerList();new Thread(new Runnable() {@Overridepublic void run() {loadMoreData();}}).start();break;}case 2:{Bundle bundle = msg.getData();String message = bundle.getString("message");Toast.makeText(ServicePersonListActivity.this, message,Toast.LENGTH_SHORT).show();break;}case 3:Toast.makeText(ServicePersonListActivity.this, "获取xxx信息失败，请稍后再试!", Toast.LENGTH_SHORT).show();break;case 4:Toast.makeText(ServicePersonListActivity.this, "网络请求失败，请稍后重试", Toast.LENGTH_SHORT).show();break;case 5:Toast.makeText(ServicePersonListActivity.this, "网络异常，请检查您的网络\"", Toast.LENGTH_SHORT).show();break;case 6:{//加载更多Bundle bundle = msg.getData();ArrayList<ServicePersonShortBean> moreServicePersonShortBeanList = (ArrayList<ServicePersonShortBean>) bundle.getSerializable("moreServicePersonShortBeanList");servicePersonShortBeanList.addAll(moreServicePersonShortBeanList);servicePersonAdapter.notifyDataSetChanged();break;}default:break;}}};

注：链式调用写法举例

FormBody formBody = formBody = new FormBody.Builder().add("token", token).add("id", id).build();
