解决方案

这个答案可以适用于任何ViewPager其实不管是您正在使用实现无标签的标签，甚至一个正常的ViewPager库。

您使用的是 neokree / MaterialTabs 库备份与ViewPager，负责刷卡的效果您可以通过提供自己的自定义ViewPager禁用。

这个类提供了启用快速滑动一个ViewPager，你可以通过 mViewPager.setPagingEnabled关掉它（假）;

没有提及的是，你必须在XML布局更改为新的自定义ViewPager，而不是原来的。

I set up sliding tabs with two Fragments each Fragment has a Button which goes to a WebView. The problem with this is when the WebView Button is clicked the sliding tabs are still activated and when a user tries to navigate within the WebView you end up swiping to the other tab. Is there a way in an on click method to disable the swiping ability of the tabs? Any help would be hugely appreciated!

Here the code:

public class MyWebViewClass extends Fragment {

private WebView mWebView;
private Button mButton;

public MyWebViewClass() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.fragment_webview, container, false);

    mWebView = (WebView) view.findViewById(R.id.WebView);

    mButton = (Button) view.findViewById(R.id.Button1);
    mButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mWebView.setVisibility(View.VISIBLE);
            mButton.setVisibility(View.GONE);
            mWebView.getSettings().setJavaScriptEnabled(true);
            mWebView.loadUrl("www.google.com");
        }
    });

    return view;
}

解决方案

This answer can be applied to any ViewPager actually no matter what is the library you are using to implement the tabs or even a normal ViewPager without tabs.

The library you are using neokree/MaterialTabs is backed with a ViewPager that is responsible for the swiping effect and you can disable that by providing your own custom ViewPager.

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;

/**
 * Created by hegazy on 2/13/15.
 */
public class CustomViewPager extends android.support.v4.view.ViewPager{
    private boolean enabled;

    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.enabled = true;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return enabled ? super.onTouchEvent(event) : false;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        return enabled ? super.onInterceptTouchEvent(event) : false;
    }

    public void setPagingEnabled(boolean enabled) {
        this.enabled = enabled;
    }

    public boolean isPagingEnabled() {
        return enabled;
    }

}

This class provides a ViewPager that is swiping enabled and you can turn it off by mViewPager.setPagingEnabled(false);

No to mention that you have to change the xml layout to your new custom ViewPager rather than the original one.

<android.support.v4.view.ViewPager 
   ...
   />

to

<my.package.CustomViewPager 
   ...
   />
