xutils3基本使用 | 易学教程

根目录下新建一个类继承application，调用xUtils3初始化方法 public class AtguiguApplication extends Application {     @Override     public void onCreate() {         super.onCreate();         //xUtils3初始化         x.Ext.init(this);         // 是否输出debug日志, 开启debug会影响性能.         x.Ext.setDebug(true);     } }  manifest配置application name   <application         android:name=".AtguiguApplication"
