Android — How to allow horizontal and vertical scr

Question

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?

Answer 1

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>
