在Viewpager滚动web视图 [英] Scroll Webview in Viewpager

问题描述

我有一个Viewpager一个web视图。 而Viewpager似乎cosume所有的横向滚动，使我不能在web视图滚动（垂直作品）。

I have a Webview in a Viewpager. And the Viewpager seems to cosume all the horizontal scrolling, so that i can´t scroll in the webview (vertical works).

我怎样才能做到这一点web视图已得到优先消耗水平滚动？

How can I achieve that the Webview has got priority consuming the horizontal scrolling?

推荐答案

不要问我为什么这个code被格式化这个样子，

don't ask me why this code gets formatted like this,

1。实现自定义ViewPager实例是这样的：

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。在主（ViewPager）活动添加以下行到视图寻呼机

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​​缩放级别是初始变焦 改变是允许的网页，其他所有的时间，你可以浏览您的Web视图

3. finally, run it :=) if the zoom level is at initial zoom, changes pages is allowed, all the other time you can navigate your web view

PS： *的不要忘记的*与您刚刚创建的CustomViewPager类更改ViewPager在你的* .xml文件

Ps.: *Don't forget* to change your ViewPager in your *.xml file with the CustomViewPager Class you just created

好运气：）
