Question

片段中有WebView。有时当我向下滚动时，视图会上升，反之亦然。我加载WebView的代码是：

webView = (WebView)v.findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.getSettings().setDomStorageEnabled(true);


webView.setWebChromeClient(new WebChromeClient(){

    public void onProgressChanged(WebView view, int progress) {
        getActivity().setTitle("Loading...");
        getActivity().setProgress(progress * 100);
        if(progress == 100)
           getActivity().setTitle("2Mummy");
        }
});

webView.loadUrl("http://my_url_here");

webView.setOnKeyListener(new View.OnKeyListener(){

    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_BACK
                && event.getAction() == MotionEvent.ACTION_UP
                && webView.canGoBack()) {
           handler.sendEmptyMessage(1);
           return true;
        }
        return false;
     }
});

webView.setWebViewClient(new WebViewClient() {
    public boolean shouldOverrideUrlLoading(WebView view, String url){
        view.loadUrl(url);
        if ((webView.canGoBack()) || (url!=url)){

        }
        else{

        }
        return false; 
    }

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon){

    }

    @Override
    public void onPageFinished(WebView view, String url){
         webView.setVisibility(View.VISIBLE);
    }

});
webView.scrollTo(0,webView.getContentHeight());

我的片段xml是

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/categoriesfrag"
    tools:context="com.quadcircles.tomummy.Fragment.Categories">

<WebView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/webView"/>

当我从手机加载网站时，它会完美滚动，当我在WebView中加载同一网站时会出现问题。感谢您的建议
