android webview导致空指针

Question

I have this in my layout :

<WebView 
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
/>

This in my activity:

public class Shop extends Activity {
@Override protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    WebView webview;
    webview = (WebView) findViewById(R.id.webview);
    webview.getSettings().setJavaScriptEnabled(true);
    webview.loadUrl("http://www.example.co.uk/shop");
}
}

and this in the manifest:

<uses-permission android:name="android.permission.INTERNET" />

Yet when i run the application, i get a force close error and something about a null pointer in the log.. I've never used webview before so have no idea what i'm doing!

Answer 1

Add setContentView(R.layout.your_layout); :

super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout);
