Stop loading Webview in react native

I have react native project on Android platform.I have a Webview loaded from url. When user click any url, i want navigate to screen in my app and webview will stop loading. So in my onNavigationStateChange() function

  source = {{uri:this.props.htmlUrl}}    ref='_webView'    scrollEnabled={true}    javaScriptEnabled={true}    domStorageEnabled={true}    onNavigationStateChange ={(navState)=>{      //handle navigate another screen       this.refs._webView.stopLoading();    }}

It works. So when i go back, and click other url, I can not touch any url in webview.If someone meet the same issue, please help me. Thanks in advance.
