View层接口

注册的

public interface NewsView  {    void LoginTrueS();    void LoginFalseS();    void LoginTrue();    void LoginFalse();}

登录的

public interface ViewDenglu {    void LoginTrueS();    void LoginFalseS();    void LoginTrue();    void LoginFalse();}

总结口

public interface JieKoiHuiDiao  {    void JieKoiHuiDiaoTrueS();//用于做判断    void JieKoiHuiDiaoFalseS();//用于做判断    void JieKoiHuiDiaoTrue();//用于传值    void JieKoiHuiDiaoFalse();//用于传值}

Modle层注册接口

public interface NewsMoudle  {    //在接口里下两个方法到类里去实现接口并且实现方法    void LoginFalse(Context context,String name,String paw);    void LoginTrue(Context context,String name,String paw);}

这里用到的是OkHttp请求数据那就需要自己封装了
这是用到的网络权限
<uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
这是用到的依赖
compile 'com.android.support:appcompat-v7:26.0.0-alpha1'compile 'com.jakewharton:butterknife:7.0.0'compile 'com.squareup.okhttp3:okhttp:3.2.0'compile 'com.squareup.okio:okio:1.7.0'compile 'com.squareup.okhttp3:logging-interceptor:3.2.0'compile 'com.squareup.picasso:picasso:2.5.2'compile files('libs/gson-2.2.4.jar')
下面是把EdText输入框变成框框
android:background="@android:drawable/alert_light_frame"
