我正在使用 Android 应用程序来显示网络错误。
NetErrorPage.java
package exp.app;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class NetErrorPage extends Activity implements OnClickListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.neterrorlayout);
Button reload=(Button)findViewById(R.id.btnReload);
reload.setOnClickListener(this);
showInfoMessageDialog("Please check your network connection","Network Alert");
}
public void onClick(View arg0)
{
if(isNetworkAvailable())
{
Intent myIntent = new Intent((Activity)NetErrorPage.this, MainActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
((Activity)NetErrorPage.this).startActivity(myIntent);
finish();
}
else
showInfoMessageDialog("Please check your network connection","Network Alert");
}
public void showInfoMessageDialog(String message,String title)
{
AlertDialog alertDialog = new AlertDialog.Builder(NetErrorPage.this).create();
alertDialog.setTitle("Network Alert");
alertDialog.setMessage(message);
alertDialog.setButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int which)
{
dialog.cancel();
}
});
alertDialog.show();
}
private boolean isNetworkAvailable()
{
NetworkInfo ActiveNetwork;
@SuppressWarnings("unused")
String IsNetworkConnected;
@SuppressWarnings("unused")
String ConnectionType;
ConnectivityManager connectivitymanager;
connectivitymanager=(ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
try
{
ActiveNetwork=connectivitymanager.getActiveNetworkInfo();
ConnectionType=ActiveNetwork.getTypeName();
IsNetworkConnected=String.valueOf(ActiveNetwork.getState());
return true;
}
catch(Exception error)
{
return false;
}
}
}
但我收到如下错误,

我已经搜索了更多......但我没有任何正确的想法来清除这个。
我想要的是,在加载此页面时,应添加布局并显示对话框。
请帮我清除此错误
注意:我也试过这个
@Override
protected void onResume() {
super.onResume();
runOnUiThread(new Runnable() {
public void run() {
showInfoMessageDialog("Please check your network connection","Network Alert");
}
});
}
