How To Get Width And Height Of A Webview In Android

I want to determine the width and the height of the WebView. I have already tried it using: webView.getWidth(); webView.getHeight(); but the resulting log always shows them to be

Solution 1:

Here's a more elegant solution

publicvoidonCreate(Bundle savedInstanceState) {


        webView = (WebView) findViewById(R.id.webView1);

        webView.addOnLayoutChangeListener(newOnLayoutChangeListener() {

            @OverridepublicvoidonLayoutChange(View v, int left, int top, int right,int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
                 int w= webView.getWidth();
                 int h= webView.getHeight();


            }
        });



    }   

Solution 2:

The onPageFinished call back approach does not work when using loadData or loadDataWithBaseURL. I saw another solution on Andromedev using JavaScript, but I'm not convinced that this is the best path to take.

Solution 3:

You were probably checking for the sizes too soon, most likely in the onCreate. Instead, try this:

webView.setWebViewClient(newWebViewClient() {
            @OverridepublicvoidonPageFinished(WebView webView, String url) {
                super.onPageFinished(webView, url);
                Log.i(TAG, findViewById(R.id.my_component).getWidth(););
            }
        });

Solution 4:

For anyone else who still struggles. Use these methods to get the height and the width of your webview.

computeHorizontalScrollRange(); -> for widthcomputeVerticalScrollRange(); -> for height

Solution 5:

Hmmm - I looked through the WevView source and I can see that internally they are using View#getWidth and View#getHeight here's one of the WebView's private methods:

/*
 * Return the width of the view where the content of WebView should render
 * to.
 */privateintgetViewWidth() {
    if (!isVerticalScrollBarEnabled() || mOverlayVerticalScrollbar) {
        return getWidth();
    } else {
        return getWidth() - getVerticalScrollbarWidth();
    }
}

As noted in the comments you have to make sure you are measuring it after you assign the activity layout e.g. setContentView(R.layout.mylayout);
