? ? ? 說在前面的話，以前寫過一次這個變態代碼，后來重構，把那個new的語法簡化了，最近又要整，差點都想不起來了，留個文檔把

1、下面這個案例更變態，抽象類還有一個個泛型類：首先內部抽象類的定義：

/*?

?*?

?*?Created?by?stone?

?*?

?*?

?*/??

package?net.stoneapp.quanshi.qsand.application;??

??

import?android.app.Application;??

import?android.util.Log;??

import?android.widget.Toast;??

??

import?com.alibaba.fastjson.JSON;??

import?com.alibaba.fastjson.JSONObject;??

??

import?net.stoneapp.quanshi.qsand.utils.AndUtils;??

??

import?cn.jpush.android.api.JPushInterface;??

import?retrofit2.Call;??

import?retrofit2.Response;??

import?rx.Subscriber;??

??

/**?

?*?Created?by?dengel?on?15/12/28.?

?*/??

public?class?QsandApplication?extends?Application?{??

????AndUtils?mAndUtils;??

??

????@Override??

????public?void?onCreate()?{??

????????super.onCreate();??

????????mAndUtils?=?new?AndUtils(this);??

????????JPushInterface.setDebugMode(true);??

????????JPushInterface.init(this);??

????}??

??

????public?AndUtils?getAndUtils(){??

????????return?mAndUtils;??

????}??

????public?abstract?class?JSONSubscriber?extends?Subscriber<JSONObject>?{??

????????@Override??

????????public?void?onCompleted()?{??

??

????????}??

??

????????@Override??

????????public?void?onError(Throwable?e)?{??

????????????if(e.getMessage()!=null)?{??

????????????????Log.i("Subscriber?Error",?e.getMessage());??

????????????????Toast.makeText(QsandApplication.this,?e.getMessage(),?Toast.LENGTH_LONG).show();??

????????????}??

????????????e.printStackTrace();??

??

????????}??

??

????}??

????public?abstract?class?Callback<T>?implements?retrofit2.Callback<T>{??

????????@Override??

????????public?void?onResponse(Call<T>?call,?Response<T>?response)?{??

????????????int?status?=?response.code();??

????????????if(status>=400?&&?status<500){??

????????????????JSONObject?jsonObj?=??(JSONObject)JSON.parse(response.errorBody().toString());??

????????????????Toast.makeText(QsandApplication.this,jsonObj.getString("detail"),Toast.LENGTH_SHORT).show();??

????????????}??

????????}??

??

????????@Override??

????????public?void?onFailure(Call<T>?call,Throwable?t)?{??

??

????????????if(t.getMessage()!=null)?{??

????????????????Log.e("Callback?Error:",?t.getMessage());??

????????????????Toast.makeText(QsandApplication.this,?t.getMessage(),?Toast.LENGTH_LONG).show();??

????????????}??

????????????t.printStackTrace();??

??

????????}??

??

????}??

}??

?

?

2、匿名類初始化方法：

?

public?void?postVerifyCode(View?view){??

????????mMobilelView.setError(null);??

????????String?mobile?=?mMobilelView.getText().toString();??

????????boolean?cancel?=?false;??

????????View?focusView?=?null;??

????????if?(TextUtils.isEmpty(mobile)?||?!StringUtils.isMobileNumber(mobile))?{??

????????????mMobilelView.setError(getString(R.string.error_invalid_mobile));??

????????????focusView?=?mMobilelView;??

????????????cancel?=?true;??

????????}??

????????if?(cancel){??

????????????focusView.requestFocus();??

??

??

????????}else?{??

????????????showProgress(true);??

????????????Services.AuthService?service?=?Services.getRetrofit().create(Services.AuthService.class);??

????????????User?user?=?new?User();??

????????????user.setMobile(mobile);??

????????????final?QsandApplication?qsandApplication?=?(QsandApplication)getApplication();??

????????????service.postVerifyCode(user).enqueue(qsandApplication.new?Callback<User>(){//重點就在這句new的語法??

????????????????@Override??

????????????????public?void?onResponse(Call<User>?call,?Response<User>?response)?{??

??

????????????????}??

??

??

??

??

????????????});??

????????}??

??

??

????}??
