How to change WebView Height?

I load in WebView some table from res. These tables 开发者_运维技巧have a different size. How do I change the size of the height of the WebView content?

I tried:

LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,
                                LayoutParams.WRAP_CONTENT);
                        myWebView.setLayoutParams(params);

after load content but it doesn't work...

you can change it in layout as

android:layout_height="300dp "

first you can set size your table layout then you set the your webview height
