在Viewpager中滚动Webview

Question

我有WebView一个ViewPager.并且ViewPager似乎消耗了所有的水平滚动,因此我无法滚动WebView(垂直工作).

如何实现WebView优先消耗水平滚动？

Answer 1

不要问我为什么这个代码被格式化为这样,

1.实现一个自定义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;
    }
}

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) {

            }
        });

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

PS:*不要忘记*更改ViewPager与刚创建的CustomViewPager类的*.xml文件

祝好运 :)
