WebView不起作用

[英]WebView doesn't work

I'm just a beginner in Android and I started to deal with webViews. 我只是Android的初学者,所以我开始处理webViews。 Indeed, I have created two button that will take me into two different activities but when I run the application the webview doesn't load the page which is Google.com. 确实,我已经创建了两个按钮,可以将我带入两个不同的活动,但是当我运行该应用程序时,webview不会加载Google.com页面。 I already inserted the internet permission. 我已经插入了互联网许可。

Here, I did onClick method as an attribute in the button that when I click on it has to go to the twitter website. 在这里,我将onClick方法作为按钮中的一个属性,当我单击它时,它必须转到twitter网站。 I put it in a different activity class. 我把它放在另一个活动类中。

 public void listen(View v)
 {
    Intent intent = new Intent(getApplicationContext(), onemore.class);
    startActivity(intent);          
 }

this is the activity class 这是活动课

package com.example.aboutme;

    import android.app.Activity;
    import android.os.Bundle;
    import android.webkit.WebView;


    public class onemore extends Activity 
    {
          private String uagent = "Mozilla/5.0 (Linux; U; Android 2.0; en-us; 
                                   Droid Build/ESD20) AppleWebKit/530.17 
                                   (KHTML, like Gecko) Version/4.0 Mobile 
                                   Safari/530.17";

        public void onCreate(Bundle savedInstanceState) 
        {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.twomore);
            displayTweets();
        }


        private void displayTweets() 
        {
            WebView mWebView = (WebView) findViewById(R.id.webView1);
            mWebView.getSettings().setJavaScriptEnabled(true);

            mWebView.getSettings().setUserAgentString(uagent); 

            mWebView.loadUrl("http://mobile.twitter.com/");
        }

    }

the xml layout xml布局

<?xml version="1.0" encoding="utf-8"?>
    <WebView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/webView1" 

    />

the manifest xml 清单xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.aboutme"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />



    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <activity
            android:name=".WebViewActivity"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar" />


        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

        </activity>
     <activity android:name=".ActivityTwo" android:label="@string/app_name"/>

    </application>

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

</manifest>

Do you have this line in your manifest? 您的清单中有这行吗? I did not see it, but maybe you changed the name for the SO question from ActivityTwo. 我没有看到它,但是也许您从ActivityTwo中更改了SO问题的名称。

activity android:name=".onemore"> 活动android:name =“。onemore”>

Your code worked fine when I ran it. 当我运行它时,您的代码运行良好。 What was the error message you were getting? 您收到的错误消息是什么?
