Android 三星'；s ListView在存在Web视图的情况下过度滚动时导致布局问题

三星已经定制了

ListView

，因此它总是能够进行overscroll，而忽略了

setOverScrollMode（）

等函数。这对我来说很好，直到现在我都有与之相关的布局问题

我需要一个显示普通项目的

列表视图

，并使用

WebView

在某些预定义的行号插入一些行内广告。为了能够重用代码，我创建了一个基本适配器，所有其他适配器都对其进行了扩展

InRowAdAdapter.java

public class InRowAdAdapter extends BaseAdapter {
    private final Context mContext;
    private SparseArray<WebView> webViews;

    private OnInRowAdItemClickListener mListener = null;

    public void setOnInRowAdItemClickListener(
            OnInRowAdItemClickListener listener) {
        mListener = listener;
    }

    public interface OnInRowAdItemClickListener {
        public void onInRowAdItemClick(View v);
    }

    public InRowAdAdapter(Context context) {
        mContext = context;
        webViews = new SparseArray<WebView>();
    }

    @Override
    public int getCount() {
        return 0;
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final int adCount = webViews.size();
        for (int i = 0; i < adCount; i++) {
            ((ViewGroup) convertView)
                    .removeView(webViews.get(webViews.keyAt(i)));
        }

        if (AdManager.isAdRow(position)) { // If this row is pre-defined to show ads
            if (webViews.get(position) == null) {
                webViews.put(position, AdManager.addAd(mContext,
                        (ViewGroup) convertView, MyApp.URL_ROW_AD));
            } else {
                try {
                    AdManager.addAd((ViewGroup) convertView,
                            webViews.get(position));
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            webViews.get(position).setVisibility(View.VISIBLE);
            convertView.setClickable(true);
            // To fix that onItemClick() is not working
            convertView.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    if (mListener != null)
                        mListener.onInRowAdItemClick(v);
                }

            });
        }
        return convertView;
    }

    protected Context getContext() {
        return mContext;
    }

}

public class AdManager {


    /**
     * Create a new WebView and add it to the supplied ViewGroup.
     * 
     * @return The created WebView
     **/
    public static WebView addAd(final Context context,
            final ViewGroup container, final String adUrl) {
        final WebView webView = new WebView(context);
        webView.setVisibility(View.GONE);
        webView.loadUrl(adUrl);
        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true);

        // webView.setInitialScale((Math.round(adHeight / BOTTOM_AD_MIN_HEIGHT
        // * 100)) + 2);
        webView.setClickable(true);
        webView.setWebViewClient(new WebViewClient() {

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                Intent urlIntent = new Intent(
                        android.content.Intent.ACTION_VIEW, Uri.parse(url));
                urlIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(urlIntent);
                return true;
            }

        });
        addAd(container, webView);
        return webView;
    }

    /**
     * Add the webView to the bottom of the supplied ViewGroup. If a
     * LinearLayout is passed to this function, please make sure that its
     * orientation is vertical.
     **/
    public static void addAd(final ViewGroup container, final WebView webView) {
        if (container instanceof RelativeLayout) {
            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                    LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
            params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
            params.addRule(RelativeLayout.BELOW,
                    container.getChildAt(container.getChildCount() - 1).getId());
            container.addView(webView, params);
        } else if (container instanceof LinearLayout) {
            LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                    LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
            container.addView(webView, params);
        }
    }
}

public class MyAdapter extends InRowAdAdapter {
    private final List<Product> products;

    public static class ViewHolder {
        public TextView vBrand;
        public TextView vProduct;
        public SmartImageView vImage;
        public TextView vDescription;
        public String id;
    }

    public MyAdapter(Context context, List<Product> products) {
        super(context);
        this.products = products;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if (convertView == null) {
            LayoutInflater inflater = (LayoutInflater) getContext()
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(
                    R.layout.adapter_product_new_arrival_list_item, null);
            holder = new ViewHolder();
            holder.vBrand = (TextView) convertView
                    .findViewById(R.id.brand_name);
            holder.vProduct = (TextView) convertView
                    .findViewById(R.id.product_name);
            holder.vImage = (SmartImageView) convertView
                    .findViewById(R.id.product_image);

            convertView.setTag(holder);
        } else
            holder = (ViewHolder) convertView.getTag();

        holder.vBrand.setText(products.get(position).getBrandName());

        // Let InRowAdAdapter handle the ads
        return super.getView(position, convertView, parent);
    }

    @Override
    public int getCount() {

    }

    @Override

        return products.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

}

我就是这样使用它的： MyAdapter.java

public class InRowAdAdapter extends BaseAdapter {
    private final Context mContext;
    private SparseArray<WebView> webViews;

    private OnInRowAdItemClickListener mListener = null;

            OnInRowAdItemClickListener listener) {
        mListener = listener;
    }

    public interface OnInRowAdItemClickListener {
        public void onInRowAdItemClick(View v);
    }

    public InRowAdAdapter(Context context) {
        mContext = context;
        webViews = new SparseArray<WebView>();
    }

    @Override
    public int getCount() {
        return 0;
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final int adCount = webViews.size();
        for (int i = 0; i < adCount; i++) {
            ((ViewGroup) convertView)
                    .removeView(webViews.get(webViews.keyAt(i)));
        }

        if (AdManager.isAdRow(position)) { // If this row is pre-defined to show ads
            if (webViews.get(position) == null) {
                webViews.put(position, AdManager.addAd(mContext,
                        (ViewGroup) convertView, MyApp.URL_ROW_AD));
            } else {
                try {
                    AdManager.addAd((ViewGroup) convertView,
                            webViews.get(position));
                } catch (Exception e) {

现在的问题是，通常看起来是这样的：

但是，当过卷时：

所有行都会正常移动，但由于一些奇怪的原因，我的WebView的内容不会被滚动。我们可以从截图上看出，WebView的大小没有改变。这只发生在三星设备上到底发生了什么事？我如何解决这个问题？我认为尝试禁用overscroll不是一个选项，因为三星自己编写了

ListView

感谢您阅读这篇长篇文章。

关于三星在其设备上定制

Overscroll

的说法是正确的。我在尝试编写一个覆盖

onoverscroll（）

方法的

overscrollView

时遇到了类似的问题

我不知道它是否有效，但很有可能下载

ListView的

并在应用程序中使用它可以解决您的问题

祝你好运
