第三步：将提示框中的消息存入WebElement Java bean中
获取到了prompt提示框中的消息后，接下来就是对这些已经过处理含特殊格式的消息进行解析处理了，依次得到WebElement的id、text、name等字段。
private WebElement createWebElementAndSetLocation(String information, WebView webView){ String[] data = information.split(";,"); //将消息按;,符号分割，其中;,符号是在前面执行JS时加入的 String[] elements = null; int x = 0; int y = 0; int width = 0; int height = 0; Hashtable<String, String> attributes = new Hashtable<String, String>(); try{ x = Math.round(Float.valueOf(data[5])); y = Math.round(Float.valueOf(data[6])); width = Math.round(Float.valueOf(data[7])); height = Math.round(Float.valueOf(data[8])); elements = data[9].split("\\#\\$"); }catch(Exception ignored){} if(elements != null) { for (int index = 0; index < elements.length; index++){ String[] element = elements[index].split("::"); if (element.length > 1) { attributes.put(element[0], element[1]); } else { attributes.put(element[0], element[0]); } } } WebElement webElement = null; try{ webElement = new WebElement(data[0], data[1], data[2], data[3], data[4], attributes);//将id、text、name等字段存入 setLocation(webElement, webView, x, y, width, height); }catch(Exception ignored) {} return webElement; } /** * Sets the location of a {@code WebElement} * * @param webElement the {@code TextView} object to set location * @param webView the {@code WebView} the text is shown in * @param x the x location to set * @param y the y location to set * @param width the width to set * @param height the height to set */ private void setLocation(WebElement webElement, WebView webView, int x, int y, int width, int height ){ float scale = webView.getScale(); int[] locationOfWebViewXY = new int[2]; webView.getLocationOnScreen(locationOfWebViewXY); int locationX = (int) (locationOfWebViewXY[0] + (x + (Math.floor(width / 2))) * scale); int locationY = (int) (locationOfWebViewXY[1] + (y + (Math.floor(height / 2))) * scale); webElement.setLocationX(locationX); webElement.setLocationY(locationY); } |
至此，WebElement对象中包含了id、text、name等字段，还包含了x、y坐标，知道了坐标后就可以像其它Android中的原生View一样根据坐标发送点击事件。
