我在WebView中有一个ViewPager。 并且ViewPager似乎消耗了所有水平滚动,因此我无法滚动WebView(垂直作品)。

如何实现WebView优先使用水平滚动?

不要问我为什么这个代码会像这样格式化,

<强> 1。实现自定义ViewPager实例,如下所示:

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;

public class CustomViewPager extends ViewPager {

    private MagazineWebView_WithoutFlipWebView mCurrentPageWebView_; //custom webview

    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {

        if (Constants.LOGGING) {
            Log.v(Constants.LOG_OEAMTC_APP, "CustomViewPager - onInterceptTouchEvent");
        }

        // if view zoomed out (view starts at 33.12... scale level) ... allow
        // zoom within webview, otherwise disallow (allow viewpager to change
        // view)
        if (mCurrentPageWebView_ != null && (mCurrentPageWebView_.getScale() * 100) > 34) {
            Log.v(Constants.LOG_OEAMTC_APP, "CustomViewPager - intrcepted: " + String.valueOf((mCurrentPageWebView_.getScale() * > 100)));
            this.requestDisallowInterceptTouchEvent(true);
        }
        else {
            if (mCurrentPageWebView_ != null) {
                Log.v(Constants.LOG_OEAMTC_APP,
                        "CustomViewPager - not intrcepted: " + String.valueOf(mCurrentPageWebView_.getScale() * 100));
            }
            this.requestDisallowInterceptTouchEvent(false);
        }

        return super.onInterceptTouchEvent(event);
    }

    public MagazineWebView_WithoutFlipWebView getCurrentPageWebView() {
        return mCurrentPageWebView_;
    }

    public void setCurrentPageWebView(MagazineWebView_WithoutFlipWebView currentPageWebView) {
        mCurrentPageWebView_ = currentPageWebView;
    }
}

<强> 2。在您的主(ViewPager)活动中,将以下行添加到视图寻呼机

mViewPager_ = new AwesomePagerAdapter();
        viewpapgerInLayout = (CustomViewPager) findViewById(R.id.awesomepager);
        viewpapgerInLayout.setAdapter(mViewPager_);
        viewpapgerInLayout.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageSelected(int position) {
                  viewpapgerInLayout.setCurrentPageWebView(mLstPagesWebviews_.get(position));
            }

            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

            }

            @Override
            public void onPageScrollStateChanged(int state) {

            }
        });

第3。最后,运行它:=)如果缩放级别是初始缩放, 允许更改页面,其他时间您可以浏览Web视图

Ps。: * 不要忘记 *使用您刚创建的CustomViewPager类更改* .xml文件中的ViewPager

祝你好运:)

试试这个

WebView mWebView = (WebView) findViewById(R.id.MyWebview);
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.getSettings().setSupportZoom(true);
mWebView.getSettings().setBuiltInZoomControls(true);
mWebView.getSettings().setUserAgentString("Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A543a Safari/419.3");
