Question

启动画面活动是全屏的，我正在使用以下链接检查互联网连接：

http://www.androidhive.info/2012/07/android-detect-internet-connection-status/

我已经为alertdialog RETRY和CLOSE实现了2个按钮。在关闭点击我终止应用程序。在重试时单击呼叫功能以检查互联网连接。当我尝试通过拉下设备的操作栏/状态栏来连接到互联网时，警报对话框就会消失。

我的互联网检查功能在oncreate函数的setcontentview之后调用。

以下是我的代码：

Inside on create function
cd = new ConnectionDetector(getApplicationContext());
checkInternet();


public void checkInternet()
{
    Log.i("INTERNET CONNECTION CHECKING", "CHECKING INTERNET CONNECTION");
    // get Internet status
    isInternetPresent = cd.isConnectingToInternet();

    if (isInternetPresent) 
    {
        // Internet Connection is Present
        // make HTTP requests
        //showAlertDialog(SplashScreenActivity.this, "Internet Connection", "You have internet connection", true);
    } 
    else 
    {
        // Internet connection is not present
        // Ask user to connect to Internet
        showAlertDialog(SplashScreenActivity.this, "No Internet Connection",
                "Please Retry or close.", false);
    }
}

public void showAlertDialog(Context context, String title, String message, Boolean status) 
{
    AlertDialog alertDialog = new AlertDialog.Builder(context).create();

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

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

    // Setting alert dialog icon
    //alertDialog.setIcon((status) ? R.drawable.success : R.drawable.fail);

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

    alertDialog.setButton(DialogInterface.BUTTON_NEGATIVE,"CLOSE", new DialogInterface.OnClickListener() 
    {
        public void onClick(DialogInterface dialog, int which) 
        {
            //finish();
             android.os.Process.killProcess(android.os.Process.myPid());
        }
    });

    // Showing Alert Message
    alertDialog.show();
}

尝试删除启动画面的全屏模式，这样您就可以直接访问设备的状态栏

当设备的操作栏/状态栏向下滚动时，警报对话框消失
