所以我只是让WebView工作，但我的SwipeView停止工作。
它与activity_main.xml
中的这一行有关<WebView
android:id="@+id/webView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
如果我将其更改为
<WebView
android:id="@+id/webView"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="0.9" />
它不显示webview但刷卡视图有效。

我可以点击我需要更改标签的标签，但我无法滑动以更改标签。
答案 0 :(得分：0)
您的布局xml搞砸了。您的webview位于viewPager上方并填充整个父布局。因此，您的viewpager不可见。这就是为什么你不能刷卡。你想要的是将你的webView放在viewPager-Fragment中。更好地了解http://developer.android.com/training/implementing-navigation/lateral.html它就在那里。
