ADF_222：ADF Mobile 11.1.2.4 Samples 介绍（8）：GestureDemo

开发运行环境：JDeveloper 11.1.2.4 + Android SDK r21.1

GestureDemo演示了各种手势的触发方式，比如：滑动（swipeRight，swipeLeft，swipeUp，swipeDown），按住并保持（tapHold）。

知识点：

1. 在amx:commandLink组件上设置手势

（1）在amx:commandLink滑动，触发setPropertyListener

<amx:commandLink id="pSR" text="Swipe Right (property)" inlineStyle="color:black">

    <amx:setPropertyListener from="p:SR" to="#{pageFlowScope.gesture}" type="swipeRight"/>

</amx:commandLink>

（2）在amx:commandLink滑动，触发actionListener，调用Managed Bean中的相应方法

<amx:commandLink id="mSR" text="Swipe Right (method)" inlineStyle="color:black">

    <amx:actionListener binding="#{GestureBean.SwipeRightHandler}" type="swipeRight"/>

</amx:commandLink>
（3）在amx:commandLink滑动，触发showPopupBehavior，弹出popup窗口

<amx:commandLink id="dSR" text="Swipe Right to show popup" inlineStyle="color:black">

    <amx:showPopupBehavior popupId="popup1" type="swipeRight" align="overlapBottom" alignId="pp1"/>

</amx:commandLink>

（4）在amx:commandLink滑动，触发closePopupBehavior，关闭popup窗口

<amx:commandLink id="clSR" text="Swipe Right to close popup" inlineStyle="color:black">

    <amx:closePopupBehavior popupId="popup1" type="swipeRight"/>

</amx:commandLink>

2. 在amx:listItem 组件上设置手势

（1）在amx:listItem 滑动，触发setPropertyListener

<amx:listItem id="SRp" showLinkIcon="false">

    <amx:outputText id="tSRp" value="Swipe Right (property)"/>

    <amx:setPropertyListener from="p:SR" to="#{pageFlowScope.gesture}" type="swipeRight"/>

</amx:listItem>

（2）在amx:listItem 滑动，触发actionListener，调用Managed Bean中的相应方法

<amx:listItem id="SRm" showLinkIcon="false">

    <amx:outputText id="tSRm" value="Swipe Right (method)"/>

    <amx:actionListener binding="#{GestureBean.SwipeRightHandler}" type="swipeRight"/>

</amx:listItem>
（3）在amx:listItem 滑动，触发showPopupBehavior，弹出popup窗口

<amx:listItem id="SRd" showLinkIcon="false">

    <amx:outputText id="tSRd" value="Swipe Right (popup)"/>

    <amx:showPopupBehavior popupId="popup1" type="swipeRight" align="overlapBottom" alignId="pp1"/>

</amx:listItem>

3. GestureHandler.java 代码

package mobile;

import javax.el.ValueExpression;

import oracle.adfmf.amx.event.ActionEvent;

import oracle.adfmf.framework.api.AdfmfJavaUtilities;

public class GestureHandler implements oracle.adfmf.feature.LifeCycleListener {

    public GestureHandler() {

    }

    public void activate() {

        ValueExpression ve = AdfmfJavaUtilities.getValueExpression("#{pageFlowScope.gesture}", String.class);

        String gesture = "";

        ve.setValue(AdfmfJavaUtilities.getAdfELContext(), gesture);

    }

    public void deactivate() {

    }

    public void SwipeRightHandler(ActionEvent actionEvent) {

        ValueExpression ve = AdfmfJavaUtilities.getValueExpression("#{pageFlowScope.gesture}", String.class);

        String gesture = "m:SR";

        ve.setValue(AdfmfJavaUtilities.getAdfELContext(), gesture);

    }

    public void SwipeLeftHandler(ActionEvent actionEvent) {

        ValueExpression ve = AdfmfJavaUtilities.getValueExpression("#{pageFlowScope.gesture}", String.class);

        String gesture = "m:SL";

        ve.setValue(AdfmfJavaUtilities.getAdfELContext(), gesture);

    }

    public void SwipeUpHandler(ActionEvent actionEvent) {

        ValueExpression ve = AdfmfJavaUtilities.getValueExpression("#{pageFlowScope.gesture}", String.class);

        String gesture = "m:SU";

        ve.setValue(AdfmfJavaUtilities.getAdfELContext(), gesture);

    }

    public void SwipeDownHandler(ActionEvent actionEvent) {

        ValueExpression ve = AdfmfJavaUtilities.getValueExpression("#{pageFlowScope.gesture}", String.class);

        String gesture = "m:SD";

        ve.setValue(AdfmfJavaUtilities.getAdfELContext(), gesture);

    }

    public void TapHoldHandler(ActionEvent actionEvent) {

        ValueExpression ve = AdfmfJavaUtilities.getValueExpression("#{pageFlowScope.gesture}", String.class);

        String gesture = "m:TH";

        ve.setValue(AdfmfJavaUtilities.getAdfELContext(), gesture);

    }

}
