我想检查网络状态,如果网络未连接,则表示我将在页面中显示警报对话框

这是我的密码

@Override
public void onCreate(Bundle savedInstanceState) {       
    super.onCreate(savedInstanceState);<br>
    setContentView(R.layout.activity_main);  

    // make the activity visible 
    Timer timer = new Timer();
    timer.schedule(new TimerTask() {
        @Override
        public void run() {              
             ServicesLayer objService = new ServicesLayer();
             boolean status = objService.connectedToNetwork(this);
             System.out.println("status: " + status);
             if(objService.connectedToNetwork(this)){

                callService();
             }else{

                System.out.println("Inside Network Else");

                // Display message and set flag not connected
                showAlertDialog(this, "Network Connection", "Connection to network is required for proper use of the iHelpPlus. Would you like to enable it now?" );
             }
        }
    }, 1000);    
}   

@SuppressWarnings("deprecation")
public void showAlertDialog(Context context, String title, String message) {<br/>
    AlertDialog alertDialog = new AlertDialog.Builder(context).create();<br/>

    // Setting Dialog Title
    alertDialog.setTitle(title);

    // Setting Dialog Message
    alertDialog.setMessage(message);


    // Setting OK Button
    alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            finish();
        }
    });

    // Showing Alert Message
    alertDialog.show();
}
@覆盖
创建时的公共void(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); //使活动可见 定时器=新定时器(); timer.schedule(新TimerTask(){ @凌驾 public void run(){ ServicesLayer objService=新ServicesLayer(); 布尔状态=objService.connectedtonework(this); System.out.println(“状态:+状态”); if(objService.ConnectedNetwork(本)){ callService(); }否则{ System.out.println(“内部网络其他”); //显示消息和设置标志未连接 showAlertDialog(此“网络连接”,“连接到网络是正确使用iHelpPlus所必需的。是否立即启用它?”); } } }, 1000); } @抑制警告(“弃用”) public void showAlertDialog(上下文上下文、字符串标题、字符串消息){
AlertDialog AlertDialog=新建AlertDialog.Builder(上下文).create();
//设置对话框标题 alertDialog.setTitle(标题); //设置对话框消息 alertDialog.setMessage(消息); //设置OK按钮 alertDialog.setButton(“确定”,新的DialogInterface.OnClickListener(){ public void onClick(DialogInterface dialog,int which){ 完成(); } }); //显示警报消息 alertDialog.show(); }
如果网络已连接,则表示它工作正常。。。否则,应用程序将以强制关闭错误关闭

如何在我的申请中解决上述问题

请任何人帮帮我
