Android无线测试之—UiAutomator UiScrollable API介绍五

滑动区域校准常量设置与获取

一、校准概念

校准常量指的是：滑动操作坐标时的偏移量，用来取偏移比例

二、相关API

返回值	API	描述
double	getSwipeDeadZonePercentage()	获取无接触区百分比的值，默认常量值为0.1,即10%
UiScrollable	setSwipeDeadZonePercentage(double swipeDeadZonePercentage)	设置一个部件的大小，在滑动时，视为无接触区的百分比。

三、API应用举例

package com.testuiselector;

import com.android.uiautomator.core.UiDevice;
import com.android.uiautomator.core.UiObject;
import com.android.uiautomator.core.UiObjectNotFoundException;
import com.android.uiautomator.core.UiScrollable;
import com.android.uiautomator.core.UiSelector;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;

public class Demo extends UiAutomatorTestCase {

    /**
     * @param args
     */
    public static void main(String[] args) {

        String jarName, testClass, testName, androidId;
        jarName="demo2";
        testClass="com.testuiselector.Demo";
        testName="testSwipeDeadZonePercentage";
        androidId="1";
        new UiAutomatorHelper(jarName, testClass, testName, androidId);

    }

    public void testSwipeDeadZonePercentage() throws UiObjectNotFoundException{
        UiDevice.getInstance().pressHome();
        sleep(1000);

        UiObject people=new UiObject(new UiSelector().text("People"));
        people.clickAndWaitForNewWindow();
        UiScrollable scroll=new UiScrollable(new UiSelector().className("android.widget.ListView"));

        scroll.flingForward();
        System.out.println("滑动时，无接触区百分比: "+scroll.getSwipeDeadZonePercentage());

        //滑动时，无接触区域百分比设置为50%时，基本没有滑动，因此这个滑动操作成了一个一点击操作
        scroll.setSwipeDeadZonePercentage(0.5);
        scroll.flingForward();
        System.out.println("滑动时，无接触区百分比: "+scroll.getSwipeDeadZonePercentage());
    }
}
