无法设置Android Webview宽度

Question

I have been trying to add a Webview control to my Android app on a screen using TableLayout Unfortunately whatever i try, the webview always covers the whole width of the screen The layout file contains the following code

<TableRow android:layout_gravity="center">

    <WebView
        android:id="@+id/someid"
        android:layout_width="wrap_content" 
        android:layout_height="100dp">
    </WebView>
</TableRow>

The Activity file contains the following

@Override protected void onFinishInflate(){

    WebSettings webSettings = mywebView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setBuiltInZoomControls(true);
    webSettings.setUseWideViewPort(true);
    webSettings.setLoadWithOverviewMode(true);
    webSettings.setLayoutAlgorithm(LayoutAlgorithm.NORMAL);
    mywebView.setScrollContainer(false);
    mywebView.addJavascriptInterface(new WebAppInterface(context), "Android");

}

Is there any specific reason why the control would always cover the whole screen width. The height attribute seems to work but whatever I use for android:layout_width the width is always 100% of screen width. I have tried giving a fixed value to android:layout_width as well as multiple combinations of the websettings in the java file.

Any clues why this could be happening?

Answer 1

You have to define at first the parameters of your tableRow . For example: layout_width and layout_height inside tableRow :

<TableRow android:layout_gravity="center"
          android:layout_width="wrap_content"
          android:layout_height="100dp">
<WebView
    android:id="@+id/someid"
    android:layout_width="wrap_content" 
    android:layout_height="fill_parent">
</WebView>

Strangely, wrappping the control in a LinearLayout fixed the issue

  <LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android" 
  android:layout_gravity="center"
  android:layout_width="wrap_content"
  android:orientation="vertical" 
  android:layout_height="wrap_content"> 
     <WebView
        android:id="@+id/someid"
         android:layout_height="wrap_content"
         android:layout_gravity="center"
         android:layout_width="250px"
         android:orientation="vertical" 
        >
     </WebView>
  </LinearLayout>
