我有一个WebView
应该显示 www.google.com 的基本应用程序。虽然可以通过内置浏览器访问该网站,但我无法从WebView
. 我在各种论坛上处理了大量问题并采纳了所有建议,但似乎没有任何效果。我已确保:
1.uses-permission
允许互联网访问的标签是标签的子manifest
标签。
2. 为 WebView 启用 javascript。
清单文件:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sriram.hellowebview"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-sdk
android:minSdkVersion="7"
android:targetSdkVersion="15" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".helloWebview"
android:label="@string/title_activity_hello_webview" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
布局:
<?xml version="1.0" encoding="utf-8" ?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<WebView
android:id="@+id/helloWebview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
代码:
/* Program to create sample webview.
* Steps:
* 1. Create webview.
* 2. Show some website in it.
* 3. Show some transitions as well.
