原因：ScrollView和WebView都有焦點(diǎn)和滑動(dòng)事件，高度無法自適應(yīng)，所以監(jiān)聽WebView加載后重新設(shè)置高度就可以了。
解決方案一為WebView重新設(shè)置高度：

WebSettings webSettings = webView.getSettings();  
        webSettings.setJavaScriptEnabled(true);//設(shè)置能夠解析Javascript  
        webSettings.setDomStorageEnabled(true);//設(shè)置適應(yīng)Html5的一些方法  
        webView.setWebChromeClient(new WebChromeClient());  
        webView.setWebViewClient(new WebViewClient(){  
            @Override  
            public boolean shouldOverrideUrlLoading(WebView view, String url) {  
//                return super.shouldOverrideUrlLoading(view, url);  
                webView.loadUrl(url);  
                return true;  
            }  
  
            @Override  
            public void onPageFinished(WebView view, String url) {  
//                super.onPageFinished(view, url);  
                progress.setVisibility(View.GONE);  
               //重新為WebView設(shè)置高度
                LinearLayout.LayoutParams  params = (LinearLayout.LayoutParams) webView.getLayoutParams();  
                params.width = getScreenWidth();  
                params.height = getScreenHeight()-SizeUtil.dip2px(ScreenShotByH5Activity.this,150);  
                webView.setLayoutParams(params);  
            }  
  
            @Override  
            public void onPageStarted(WebView view, String url, Bitmap favicon) {  
                super.onPageStarted(view, url, favicon);  
                progress.setVisibility(View.VISIBLE);  
            }  
  
            @Override  
            public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {  
                super.onReceivedError(view, request, error);  
                progress.setVisibility(View.GONE);  
                showToastMessage("加載失敗");  
            }  
        });  
        webView.getSettings().setJavaScriptEnabled(true);  
        webView.loadUrl(url);  

解決ScrollView和WebView的滑動(dòng)沖突（該方法是讓ScrollView和WebView都單獨(dú)滑動(dòng)效果不理想）

webView.setOnTouchListener(new View.OnTouchListener() {  
           @Override  
           public boolean onTouch(View v, MotionEvent ev) {  
               ((WebView)v).requestDisallowInterceptTouchEvent(true);  
               return false;  
           }  
       });  

解決方案二：不讓W(xué)ebView滑動(dòng)，只滑動(dòng)ScrollView

  <ScrollView
            android:id="@+id/scrollView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginBottom="@dimen/dp_20"
            android:fillViewport="true"
            android:scrollbars="none"
            android:descendantFocusability="blocksDescendants"/>

為ScrollView設(shè)置android:descendantFocusability="blocksDescendants"屬性
