我寻觅更多...但我没有任何正确的理念来清除此。
我要的是,加载这个页面时,布局应加,应显示对话框。
请帮我清除此错误
注意:我已经试过这也
@覆盖
保护无效onResume(){
super.onResume();
runOnUiThread(新的Runnable(){
公共无效的run(){
showInfoMessageDialog(请检查网络连接,网络警告);
}
});
}
谢谢你们给了我很多建议。最后,我得到了一个解决方案。这是我已经开始NetErrorPage意图两次。有一次,我已经检查了网络连接的可用性,并开始有意以页开始的事件。第二次,如果页面错误,那么我已经开始在OnReceivedError事件的意图。所以第一次对话框没有关闭,在此之前,被称为第二个对话框。所以,我得到了一个错误。
现在我已经删除了第二个电话,并清除错误: - )

I have searched more... but i don't have any right idea to clear this.
What i want is, when loading this page, layout should be added and dialog should be shown.
Please help me to clear this error
Note: I have tried this also
@Override
protected void onResume() {
super.onResume();
runOnUiThread(new Runnable() {
public void run() {
showInfoMessageDialog("Please check your network connection","Network Alert");
}
});
}
Thank you Guys to give me many suggestions. Finally I got a solution. That is i have started the NetErrorPage intent two times. One time, i have checked the net connection availability and started the intent in page started event. second time, if the page has error, then i have started the intent in OnReceivedError event. So the first time dialog is not closed, before that the second dialog is called. So that i got a error.
Now I have removed the second call and Cleared error :-).
