Question

我有一个很大的问题，我找不到解决问题的方法。

我尝试加载网址并使用本教程：http://developer.android.com/reference/android/webkit/WebView.html

我的代码：

public class HomeView extends Activity
{

    WebView mWebView;

    public void onCreate(Bundle savedInstanceState) 
    {
        try
        {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.home);

            mWebView = (WebView) findViewById(R.id.webview);
            mWebView.getSettings().setJavaScriptEnabled(true);

            mWebView.loadUrl("http://www.google.de");

        }
        catch (Exception e) {

        }
    }
}

my home.xml：

<?xml version="1.0" encoding="utf-8"?>
<WebView  xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
/>

现在我的问题。如果我启动程序一切正常。页面正在加载，我在屏幕上看到它。但是在所有内容加载后，我收到以下消息（应用程序已意外停止。请再试一次。）并且我的程序终止。

希望有人可以帮助我。

干杯，罗兰

Answer 1

我的代码只是一个小错误。

<强> @Override

public void onCreate(Bundle savedInstanceState)

使用@Override一切正常。
