TableLayout ScrollView Vertical & Horizontal

问题:

How we can setup ScrollView vertically & horizontally? I tried the below code, but it didn't work.

<ScrollView
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:background="@color/red"
 android:scrollbarFadeDuration="1000"
 android:scrollbarSize="12dip" >

   <HorizontalScrollView
     android:id="@+id/horizontalScrollView1"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content" >

      <TableLayout
        android:id="@+id/tableLayout1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:collapseColumns="2"
        android:stretchColumns="1" >
    </TableLayout>
</HorizontalScrollView>

<ScrollView >
</ScrollView>

Here is all my code : http://pastebin.com/ysRhLMyt

Try,

• Set the android:scrollbarFadeDuration="0"

             OR 
  

• ScrollView1.setScrollbarFadingEnabled(false);

             OR
  

• android:scrollbarFadeDuration="0" and

  android:scrollbarAlwaysDrawVerticalTrack="true" for vertical

  android:scrollbarAlwaysDrawHorizontalTrack="true" for horizontal

And one more thing,

Remember, the ScrollView can have only one child control, so we can make a container (Linear, relative, Table Layouts) the child of the ScrollView and put all the controls inside this child.

Nested scroll views doesn't work. It's related to scroll view touch handling: top level view always consume all touch events. You have to write you own custom scroll view.

Below code which makes horizontal and vertical scroll view, To see its effect first define a area around 200x 200 dp and paste this code inside it.

The View will scrolling horizontally as well as vertically.

<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbarSize="10dp"
android:scrollbars="vertical" >

<HorizontalScrollView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="horizontal" >

            <Button
                android:layout_width="300dp"
                android:layout_height="100dp" />

            <Button
                android:layout_width="300dp"

Try using the android:orientation attribute. This can be used for horizontal or vertical: android:orientation="horizontal" or android:orientation="vertical".

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:scrollbarFadeDuration="1000"
      android:scrollbarSize="12dip"
      android:background="@color/red" 
      android:orientation="horizontal">

      <TableLayout android:layout_width="match_parent"  
            android:layout_marginTop="10dp" 
            android:id="@+id/tableLayout1" 
            android:layout_height="wrap_content" 
            android:stretchColumns="1" 
            android:collapseColumns="2">
      </TableLayout>
</ScrollView>
