Webブラウザのチュートリアルです。HelloWebViewというプロジェクトを作成します。
res/layout/main.xmlを開き、以下のように変更します。
1 2 3 4 5 6 | <? xml version = "1.0" encoding = "utf-8" ?> < WebView xmlns:android = "http://schemas.android.com/apk/res/android" android:id = "@+id/webview" android:layout_width = "match_parent" android:layout_height = "match_parent" /> |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | <? xml version = "1.0" encoding = "utf-8" ?> < manifest xmlns:android = "http://schemas.android.com/apk/res/android" package = "jp.blogspot.logroid.helloWebView" android:versionCode = "1" android:versionName = "1.0" > < uses-sdk android:minSdkVersion = "10" /> < uses-permission android:name = "android.permission.INTERNET" /> < application android:icon = "@drawable/ic_launcher" android:label = "@string/app_name" > < activity android:name = ".HelloWebViewActivity" android:label = "@string/app_name" android:theme = "@android:style/Theme.NoTitleBar" > < intent-filter > < action android:name = "android.intent.action.MAIN" /> < category android:name = "android.intent.category.LAUNCHER" /> </ intent-filter > </ activity > </ application > </ manifest > |

URLも何も指定していないので空ページが表示されます
