解决方法
像这样创建类并在此处添加您的函数：
package com.mytest;
import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
public class MyGlobals{
Context mContext;
// constructor
public MyGlobals(Context context){
this.mContext = context;
}
public String getUserName(){
return "test";
}
public boolean isNetworkConnected() {
ConnectivityManager cm = (ConnectivityManager) mContext.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();
if (ni == null) {
// There are no active networks.
return false;
} else
return true;
}
}
然后在您的活动中声明实例：
MyGlobals myGlog;
然后初始化并使用该全局类中的方法：
myGlog = new MyGlobals(getApplicationContext()); String username = myGlog.getUserName(); boolean inConnected = myGlog.isNetworkConnected();
您的清单文件中所需的权限：
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
谢谢.
