android - Viewpager 中的垂直滚动

Question

这里我有两个文件。我想在 viewpager 中启用垂直滚动。页面内容超出页面大小。即使内容超过页面大小......我也没有滚动。请帮助。

<?xml version="1.0" encoding="utf-8"?>
    <ScrollView
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:fillViewport="true" 
      >
     <RelativeLayout    

     android:layout_width="match_parent"
     android:layout_height="wrap_content">
    <RelativeLayout      
      android:id="@+id/secAct1"
    android:layout_height="25dip"
    android:layout_width="match_parent"
    android:background="#000000"
    android:layout_alignParentBottom="true"
        >
          <TextView 
        android:id="@+id/cn1"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:layout_alignParentLeft="true"
        android:paddingLeft="10dip"
        android:textColor="@color/white"
        android:textSize="15sp"
        android:text="cn"
        />
      <TextView 
        android:id="@+id/si1"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:paddingRight="10dip"
        android:layout_alignParentRight="true"
         android:textColor="@color/white"
        android:textSize="15sp"
         android:text="si"
        />
    </RelativeLayout>
    <LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/secAct1"
    android:orientation="vertical"
    android:gravity="center"
    android:padding="30dip">
    <Button 
    android:id="@+id/submitAll"    
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"   
    android:text="Submit Responses"    
    />   
    <TextView 
    android:id="@+id/lp"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"   
    android:textColor="@color/white"
    android:text="Thank you for your valuable responses!\n On submitting, you will not be able to changes your                            responses.\nYou responses will be uploaded when your device is connected to the internet.\nThank you for your     valuable responses!\n On submitting, you will not be able to changes your responses.\nYou responses will be uploaded when your device is connected to the internet.Thank you for your valuable responses!\n On submitting, you will not be able to changes your responses.\nYou responses will be uploaded when your device is connected to the internet.Thank you for your valuable responses!\n On submitting, you will not be able to changes your responses.\nYou responses will be uploaded when your device is connected to the internet.\nThank you for your valuable responses!\n On submitting, you will not be able to changes your responses.\nYou responses will be uploaded when your device is connected to the internet.Thank you for your valuable responses!\n On submitting, you will not be able to changes your responses.\nYou responses will be uploaded when your device is connected to the internet.Thank you for your valuable responses!\n On submitting, you will not be able to changes your responses.\nYou responses will be uploaded when your device is connected to the internet.\nThank you for your valuable responses!\n On submitting, you will not be able to changes your responses.\nYou responses will be uploaded when your device is connected to the internet.Thank you for your valuable responses!\n On submitting, you will not be able to changes your responses.\nYou responses will be uploaded when your device is connected to the internet.Thank you for your valuable responses!\n On submitting, you will not be able to changes your responses.\nYou responses will be uploaded when your device is connected to the internet.\nThank you for your valuable responses!\n On submitting, you will not be able to changes your responses.\nYou responses will be uploaded when your device is connected to the internet.Thank you for your valuable responses!\n On submitting, you will not be able to changes your responses.\nYou responses will be uploaded when your device is connected to the internet."
      >
         </TextView>


        </LinearLayout>
           </RelativeLayout></ScrollView>  

下一个文件

    <?xml version="1.0" encoding="utf-8"?>

    <LinearLayout 
     xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/fragQue"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
     >

     <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"

        android:background="@drawable/radialback"
        >
    <android.support.v4.view.PagerTabStrip
            android:id="@+id/pager_title_strip"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="top"
            android:paddingTop="@dimen/fQ_P"
            android:paddingBottom="@dimen/fQ_P" 
            android:background="@color/yellow"
            android:textColor="@color/textGray" 
             /> 
    </android.support.v4.view.ViewPager > 

    </LinearLayout>

Answer 1

首先，您拥有它以便 TextView 位于 cn 和 si 按钮上方，即使按钮位于屏幕底部，它也无法按照您希望的方式工作。

android:layout_above="@+id/secAct1"
//should be
android:layout_below="@+id/secAct1"

这将为您提供顶部的提交按钮和 TextView ，以及下方的 cn 和 si 按钮，并且可以滚动。如果你想要顶部的 cn 和 si 按钮，在第二个相对布局中，更改

android:layout_alignParentBottom="true"
//to
android:layout_alignParentTop="true"

至于第二个文件，我不知道 viewpager 是否有默认滚动条，所以你可能只需要将它包装在 ScrollView 中即可。
