How to get width and height of a Webview in android

Question

I want to determine the width and the height of the WebView. I have already tried it using:

webView.getWidth();
webView.getHeight();


        

Answer 1

Here's a more elegant solution

public void onCreate(Bundle savedInstanceState) {


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

        webView.addOnLayoutChangeListener(new OnLayoutChangeListener() {

            @Override
            public void onLayoutChange(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();


            }
        });



    }   

Answer 2

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

computeHorizontalScrollRange(); -> for width 
computeVerticalScrollRange(); -> for height

Answer 3

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.
 */
private int getViewWidth() {
    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);

Answer 4

If you want to get The Height and Width load time you can't get it because load time can't get it. I suggest to use the webview Touchevent and get the height and width. Otherwise use another view click event and get the height and width.

webView.getWidth();
webView.getHeight();

Use this.

Answer 5

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.

Answer 6

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

webView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView webView, String url) {
                super.onPageFinished(webView, url);
                Log.i(TAG, findViewById(R.id.my_component).getWidth(););
            }
        });
