Android — How to allow horizontal and vertical scr

问题:

There is the ScrollView that allows only vertical scrolling, and the HorizontalScrollView that allows only horizontal scrolling, but no class for both. This seems like a pretty gaping deficit in the Android UI. Any tricks to allow this?

Try this

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

    <HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android"
                  android:layout_width="wrap_content"
                  android:layout_height="fill_parent">

         <TableLayout
                  android:id="@+id/amortization"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content">

              <TableRow
                  android:background="#ffff00">
                  <TextView
                       android:text="@string/amortization_1"
                       android:padding="3dip"/>
                  <TextView
                       android:text="@string/amortization_2"
                       android:padding="3dip"/>
                  <TextView
                       android:text="@string/amortization_3"
                       android:padding="3dip"/>
                  <TextView
                       android:text="@string/amortization_4"
                       android:padding="3dip"/>
                  <TextView
                       android:text="@string/amortization_5"
                       android:padding="3dip"/>
                  <TextView
                       android:text="@string/amortization_6"
                       android:padding="3dip"/>
                  <TextView
                       android:text="@string/amortization_7"
                       android:padding="3dip"/> 
              </TableRow>
         </TableLayout>
    </HorizontalScrollView>
</ScrollView>

An example with an ImageView:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView android:id="@+id/ScrollView02" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content"
            xmlns:android="http://schemas.android.com/apk/res/android">
<HorizontalScrollView android:id="@+id/HorizontalScrollView01" 
                      android:layout_width="wrap_content" 
                      android:layout_height="wrap_content">
<ImageView android:id="@+id/ImageView01"
           android:src="@drawable/pic" 
           android:isScrollContainer="true" 
           android:layout_height="fill_parent" 
           android:layout_width="fill_parent" 
           android:adjustViewBounds="true">
</ImageView>
</HorizontalScrollView>
</ScrollView>

I found it is important to set fillViewportbecause otherwise scroll bars might appear at random positions instead of at the right/bottom of the scrolling area:

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true" >
    <HorizontalScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fillViewport="true" >
    </HorizontalScrollView>
</ScrollView>
