我正在为 Android WebView 尝试这个示例:
http://www.linuxtopia.org/online_books/android/devguide/guide/tutorials/views/hello-webview.html
但我没有得到我想要的,这是我的文件:
MainActivity.java:
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends Activity {
private WebView webview;
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
webview.setWebViewClient(new WebClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://www.google.com");
}
private class WebClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
}
主.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<WebView
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sheya"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.INTERNET" />
<application android:label="@string/app_name" android:icon="@drawable/ic_launcher">
<activity android:name="MainActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
事实是,当我启动我的应用程序时,它会显示一个黑屏,但如果我删除
webview.setWebViewClient(new WebClient());
从应用程序代码行,它将谷歌页面打开到默认浏览器中......
- 编辑 -
解决了,在main.xml布局文件中:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" <!-- Instead of wrap_content -->
android:layout_height="fill_parent" <!-- Instead of wrap_content -->
android:orientation="vertical">
<WebView
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
