Android Studio不识别support.v4.app.FragmentTabHost的问题。
用Android Studio实现底部标签页功能,同样的代码在Eclipse里面是没有问题的,现在在AS里面预览的时候总是报错:Exception raised during rendering: No tab known for tag null
XML源码如下:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <FrameLayout android:id="@+id/realtabcontent" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" /> <View android:layout_width="fill_parent" android:layout_height="0.5dp" android:background="#BFBFBF" /> <android.support.v4.app.FragmentTabHost android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/maintab_bg" > <FrameLayout android:id="@android:id/tabcontent" android:layout_width="0dp" android:layout_height="0dp" android:layout_weight="0" /> </android.support.v4.app.FragmentTabHost> </LinearLayout>
Gradle引用了V7包
