我尝试使用滚动复合（垂直滚动）与使用手势（滑动）的分页导航相结合。
我的应用程序在Android模拟器上运行良好（尝试过Android 4.0.3,4.1.2,4.3）但我的手机出现问题 中兴Blade III，Androind OS 4.0.4。无论方向如何，滑动都不起作用 使用Android 4.4的HTC Desire在横向滑动方面存在问题
我做错了什么。
我使用SwipeDemo入口点（来自标签）进行了测试。
private void createSwipeWidget( Composite parent ) {
final ScrollingComposite scrollableParent = new ScrollingComposite( parent, SWT.V_SCROLL );
scrollableParent.setLayout( GridLayoutFactory.fillDefaults().create() );
scrollableParent.setLayoutData( GridDataFactory.fillDefaults()
.grab( true, true )
.align( SWT.FILL, SWT.FILL )
.create() );
Swipe result = new Swipe( scrollableParent, new DictionarySwipeItemProvider() );
GridDataFactory.fillDefaults()
.grab( true, true )
.align( SWT.FILL, SWT.FILL )
.applyTo( result.getControl() );
result.show( 0 );
}
同样在com.eclipsesource.tabris.demos.swipe.DictionarySwipeItem
我在.hint( SWT.DEFAULT, 500 )方法中提示createTitleLabel，以便启用垂直滚动。

答案 0 :(得分：0)
对我而言，它确实可以与模拟器（经过测试的Android SDK和Genymotion）一起使用，但对于真实设备我也会发现问题： 使用摩托罗拉Razr i ist不起作用，基于Android 4.4.2的HTC Desire和Cynogenmod只能在纵向工作，但不能在横向工作。在华硕fonepad两个方向都很好。
一个例子：
=============================================== =================================== 的 SwipeDemo.java
import com.eclipsesource.tabris.widgets.ScrollingComposite;
private void createSwipeWidget( Composite parent ) {
final ScrollingComposite scrollableParent = new ScrollingComposite( parent, SWT.V_SCROLL );
scrollableParent.setLayout( GridLayoutFactory.fillDefaults().create() );
scrollableParent.setLayoutData( GridDataFactory.fillDefaults()
.grab( true, true )
.align( SWT.FILL, SWT.FILL )
.create() );
Swipe result = new Swipe( scrollableParent, new DictionarySwipeItemProvider() );
GridDataFactory.fillDefaults()
.grab( true, true )
.align( SWT.FILL, SWT.FILL )
.applyTo( result.getControl() );
result.show( 0 );
}
=============================================== =================================== 的 DictionarySwipeItem.java
private void createTitleLabel( Composite parent ) {
Label titleLabel = new Label( parent, SWT.WRAP );
GridDataFactory.fillDefaults()
.align( SWT.CENTER, SWT.TOP )
.grab( true, true )
.hint( SWT.DEFAULT, 500 )
.applyTo( titleLabel );
titleLabel.setForeground( parent.getDisplay().getSystemColor( SWT.COLOR_DARK_GRAY ) );
titleLabel.setText( "Lesson " + ( index + 1 ) );
titleLabel.setFont( new Font( parent.getDisplay(), new FontData( "Arial", 30, SWT.BOLD ) ) );
}
