android 全局变量使用问题
全局定义变量在登录页设置值后，在登录后跳转到的页面上获取不到值，一直为空。
全局变量的定义
public class MyApplication extends Application {
private Map map;
private Connection.Response response;
public Map getMap() {
return map;
}
public void setMap(Map map) {
this.map = map;
}
public Connection.Response getResponse() {
return response;
}
public void setResponse(Connection.Response response) {
this.response = response;
}
}
