UIAutomator2.0详解（UIDevice篇----触屏操作3）

本篇将记录触屏的最后4个方法，用于点击，拖拽和滑动。

先列举一下方法
（1）public boolean click(int x, int y)，点击
（2）public boolean swipe(int startX, int startY, int endX, int endY, int steps) ，滑动
（3）public boolean swipe(Point[] segments, int segmentSteps)，滑动
（4）public boolean drag(int startX, int startY, int endX, int endY, int steps)，拖拽

可见，四个方法都是基于坐标（Point）的。
其中public boolean swipe(Point[] segments, int segmentSteps)基于坐标数组。
这里，需要做着重说明的是参数steps和segmentSteps。

steps：是指，分多少次完成这次动作。每次移动花费的时间是固定的，都为5ms。
segmentSteps：是指，点与点之间分多少次完成这次动作。同steps。

我们还是用一个示例来演示方法的功能。

代码如下：

@Test    public void FunctionKeyTest4(){        Log.i(TAG, "Start Test");        mDevice.waitForIdle(timeOut);        int h=mDevice.getDisplayHeight();        int w=mDevice.getDisplayWidth();        int left=200;        int right=w-200;        int step=50;        Log.i(TAG, "left = "+left+" Right = "+right);        //(1)From Right to Left        Log.i(TAG, "from ("+right+","+h/2+") to ("+left+","+h/2+")");        result=mDevice.swipe(right, h/2, left, h/2, step);        Log.i(TAG, "Swipe result (Right to Left) = "+result);        mDevice.waitForIdle(timeOut);        //(2)From Left to Right        Log.i(TAG, "from ("+left+","+h/2+") to ("+right+","+h/2+")");        result=mDevice.swipe(left, h/2, right, h/2, step);        Log.i(TAG, "Swipe result (Left to Right) = "+result);        mDevice.waitForIdle(timeOut);        //(3)Drag        Log.i(TAG, "Dragfrom (300,1000) to (700,1000)");        result=mDevice.drag(left, h/2, right, h/2, step);        Log.i(TAG, "Drag result (Left to Right) = "+result);        mDevice.waitForIdle(timeOut);        //(4)From Left to Right        Point[] pointArray=new Point[]{                new Point(200,h/2),new Point(300,h/2),new Point(400,h/2),new Point(500,h/2),new Point(600,h/2),new Point(700,h/2),        };        result=mDevice.swipe(pointArray, step);        Log.i(TAG, "Swipe by Array, result (Left to Right) = "+result);        mDevice.waitForIdle(timeOut);        //(5)Click        result=mDevice.click(300, 1000);        Log.i(TAG, "Click = "+result);        mDevice.waitForIdle(timeOut);    }

运行结果如下：

运行效果如下：

从运行效果看，drag并没有体现出来，跟手动的拖拽明显不同。
手动的拖拽，首先需要长按。而drag只是点击，因此无法实现拖动，从而在效果上更像是滑动。不排除是在主界面拖拽的原因。
