我在 Eclipse 中运行应用程序时遇到问题，我无法弄清楚问题所在。因为项目文件中没有错误。我已经重新安装了eclipse，之后我遇到了问题。文件

package com.goby.bus;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class GobybusActivity extends Activity {
    WebView mWebView;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);


        mWebView = (WebView) findViewById(R.id.webview);
        mWebView.getSettings().setJavaScriptEnabled(true);
        mWebView.loadUrl("file:///android_asset/index.html");
        mWebView.setWebViewClient(new mWebViewClient());
        mWebView.setBackgroundColor(Color.WHITE);
    }



    private class mWebViewClient extends WebViewClient {        

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }

}

似乎 XML 中指定的活动名称与您的类名称不匹配，如下行所示：

04-22 11:21:54.618: E/AndroidRuntime(623): 由: java.lang.ClassNotFoundException: com.goby.bus.MainActivity in loader dalvik.system.PathClassLoader [/data/app/com.goby.bus -1.apk]

在您的 android 清单 XML 中，更改

<activity android:name=".MainActivity "  ... >

至

<activity android:name=".GobybusActivity"  ... >

移动

WebView mWebView;

以上

mWebView = (WebView) findViewById(R.id.webview);
