网络连接部分

项目部分总结：

Application

写一个AppApplication继承Application

package com.redcircle.redcircle;import android.app.Application;import android.content.Context;/** * Created by Administrator on 2015/10/10. */public class AppApplication extends Application {    private static AppApplication mApplication;    @Override    public void onCreate() {        super.onCreate();        //程序初始化        mApplication = this;        DbManager.newInstance().getDb();    }    public static AppApplication getApplication(){        return mApplication;    }}

BaseActivity

写一个BaseActivity继承AppCompatActivity，实现他的方法，然后所有的Activity都继承BaseActivity。

package com.redcircle.redcircle;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;/** * Created by Administrator on 2015/10/10. */public class BaseActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);    }    @Override    protected void onPostResume() {        super.onPostResume();    }    @Override    protected void onStop() {        super.onStop();    }    @Override    protected void onDestroy() {        super.onDestroy();    }}

BaseFragment

写一个BaseFragment 继承Fragment，实现他的方法。

package com.redcircle.redcircle;import android.app.Fragment;import android.os.Bundle;/** * Created by Administrator on 2015/10/10. */public class BaseFragment extends Fragment {    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);    }    @Override    public void onResume() {        super.onResume();    }    @Override    public void onPause() {        super.onPause();    }    @Override    public void onStop() {        super.onStop();    }    @Override    public void onDestroy() {        super.onDestroy();    }}

网络连接部分

网络连接部分写一个包Http，所有关于网络连接的类都放在这个包里,

网络连接的类MyHttp

package com.redcircle.redcircle.Http;import android.app.DownloadManager;import android.content.Context;import com.android.volley.AuthFailureError;import com.android.volley.Request;import com.android.volley.RequestQueue;import com.android.volley.Response;import com.android.volley.VolleyError;import com.android.volley.toolbox.StringRequest;import com.android.volley.toolbox.Volley;import com.redcircle.redcircle.AppApplication;import com.redcircle.redcircle.utils.NetWorkUtils;import java.util.HashMap;import java.util.Map;/** * Created by Administrator on 2015/10/10. * 所有的网络连接全部使用此类，此类的作用是统一网络连接的接口 */public class MyHttp {    //单例设计模式    private MyHttp(){}    private static MyHttp mMyHttp;    public synchronized static MyHttp newInstance(){        if (mMyHttp == null){            mMyHttp = new MyHttp();        }        return mMyHttp;    }    //此处是观察者模式，监听网络连接    public interface OnHTTPConnectionListener{        //无网络可用        public void NullInternet();        //网络连接失败        public void FailConnection(int errocode);        //成功        public void SuccessConnection(String response);    }    public void addRequest(String url, HashMap<String, String> params,final OnHTTPConnectionListener onHTTPListener){        //无网络连接时调用        if (!NetWorkUtils.isConnection()){            onHTTPListener.NullInternet();            return;        }        RequestQueue queue = Volley.newRequestQueue(AppApplication.getApplication());        StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {            @Override            public void onResponse(String response) {                onHTTPListener.SuccessConnection(response);            }        }, new Response.ErrorListener() {            @Override            public void onErrorResponse(VolleyError error) {                onHTTPListener.NullInternet();            }        }){            @Override            protected Map<String, String> getParams() throws AuthFailureError {                HashMap hashMap=params;                return hashMap;            }        };        queue.add(stringRequest);//        MyHttp.newInstance(new AppApplication().getmContext()).    }}

专门存放特定字符串的类NetWorkConfig，比如URL

package com.redcircle.redcircle.Http;/** * Created by Administrator on 2015/10/10. */public class NetWorkConfig {    public static final String URL = "http://www.baidu.com";}

区分各部分网络连接的方法，比如登录、注册

package com.redcircle.redcircle.Http;import java.util.HashMap;/** * Created by Administrator on 2015/10/10. */public class MyAllHttpMethod {    //需要加单例    public static void login(){    }    public static void regester(){    }}

还要判断是否有网络可用，如果没有，提示打开WiFi或数据

package com.redcircle.redcircle.utils;import android.content.Context;import android.net.ConnectivityManager;import android.net.NetworkInfo;import android.telephony.TelephonyManager;import com.redcircle.redcircle.AppApplication;/** * Created by Administrator on 2015/10/10. */public class NetWorkUtils {    public static boolean isConnection(){        ConnectivityManager mConnectivity = (ConnectivityManager)AppApplication.getApplication().getSystemService(Context.CONNECTIVITY_SERVICE);        // 检查网络连接，如果无网络可用，就不需要进行连网操作等        NetworkInfo info = mConnectivity.getActiveNetworkInfo();        if (info == null || !mConnectivity.getBackgroundDataSetting()) {            return false;        }        return true;    }}
