我有一个错误在Android简单demo.I处理有我的互联网例行检查，并用重载调用网页视图当我点击一个menu.Here是我的代码网页视图崩溃点击
package com.example.test;
import android.app.Activity;
import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends Activity {
public static final int DIALOG_NONETWORK = 0;
WebView mywebview=null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final WebView mywebview = (WebView) findViewById(R.id.webview);
if(!Connection()){
String data = "<html>" +
"<body><h1>NO INTERNET</h1></body>" +
"</html>";
mywebview.loadData(data, "text/html", "UTF-8");
Log.v("INTERNET","NO");
}else{
mywebview.loadUrl("http://www.google.com");
Log.v("INTERNET","YES");
}
mywebview.setWebViewClient(new WebViewClient() {
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
String data = "<html>" +
"<body><h1>NO INTERNET</h1></body>" +
"</html>";
mywebview.loadData(data, "text/html", "UTF-8");
}
});
}
public boolean Connection() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfoMob = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
NetworkInfo netInfoWifi = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
if ((netInfoMob != null || netInfoWifi != null) && (netInfoMob.isConnectedOrConnecting() || netInfoWifi.isConnectedOrConnecting())) {
return true;
}
return false;
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.action_settings:
mywebview.reload();
Log.v("INTERNET","RELOAD");
break;
}
return super.onOptionsItemSelected(item);
}
}
当我点击菜单“action_settings”应用程序是在重载fucntion.I刚刚坠毁怀疑它与mywebview.setWebViewClient(new WebViewClient()或final WebView mywebview = (WebView) findViewById(R.id.webview);
任何帮助或recomedations办？
