android - 带有通知栏的Android WebView

我想使我的Web应用程序看起来像本机应用程序一样，现在我才意识到顶部没有通知栏，并且Android后退按钮不会带您到最后一个屏幕，而是关闭了该应用程序。有人知道如何解决此问题吗？

<uses-sdk
    android:minSdkVersion="7"
    android:targetSdkVersion="16" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme"
    android:hardwareAccelerated="true">
    <activity
        android:name="com.example.mywebapp.MainActivity"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

活动

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final String URL = "file:///android_asset/Compatibilidades/public_html/index.html";
    WebView myWebView = (WebView) this.findViewById(R.id.webView);
    myWebView.setWebViewClient(new MyWebViewClient());
    myWebView.getSettings().setJavaScriptEnabled(true);
    myWebView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
    myWebView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
    myWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
    myWebView.loadUrl(URL);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
    return false;
}
}

布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">


<WebView
        android:id="@+id/webView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
/>

</LinearLayout>

最佳答案

找到解决方案后，您需要将此参数放入AndroidManifest.xml中的活动中

<activity
    android:theme="@android:style/Theme.NoTitleBar">
