ViewServer接受hierarchyviewer的命令

AUTOLIST

线程阻塞，命令发送后，会等待viewserver反馈结果。viewserver在检测到界面跳转以后才会回馈结果。

private class WindowChangeMonitor implements Runnable {private IDevice device;public WindowChangeMonitor(IDevice device) {this.device = device;}public void run() {while (!Thread.currentThread().isInterrupted()) {DeviceConnection connection = null;try {connection = new DeviceConnection(this.device);connection.sendCommand("AUTOLIST");String line;while ((!Thread.currentThread().isInterrupted())&& ((line = connection.getInputStream().readLine()) != null)) {if (line.equalsIgnoreCase("LIST UPDATE")) {}if (line.equalsIgnoreCase("FOCUS UPDATE")) {}show(line);}} catch (IOException e) {} finally {if (connection != null)connection.close();}}}}

以上程序运行后，会一直等待，知道界面有跳转。反馈的结果有2种：LIST UPDATE和FOCUS UPATE。输出结果如下：

Appiot----------------LIST UPDATEAppiot----------------FOCUS UPDATEAppiot----------------LIST UPDATEAppiot----------------LIST UPDATEAppiot----------------LIST UPDATE

一个界面的跳转有一个FOCUS UPDATE事件触发，但是会触发若干LIST UPDATE事件。

GET_FOCUS

得到当前设备上显示的界面的activity。

在刚才代码的基础上，当检测到界面跳转时，获得跳转后的activity.

private class WindowChangeMonitor implements Runnable {private IDevice device;public WindowChangeMonitor(IDevice device) {this.device = device;}public void run() {while (!Thread.currentThread().isInterrupted()) {DeviceConnection connection = null;try {connection = new DeviceConnection(this.device);connection.sendCommand("AUTOLIST");String line;while ((!Thread.currentThread().isInterrupted())&& ((line = connection.getInputStream().readLine()) != null)) {if (line.equalsIgnoreCase("LIST UPDATE")) {}if (line.equalsIgnoreCase("FOCUS UPDATE")) {getWindowId();}show(line);}} catch (IOException e) {} finally {if (connection != null)connection.close();}}}public void getWindowId(){DeviceConnection connection = null;try {connection = new DeviceConnection(this.device);connection.sendCommand("GET_FOCUS");String line;while ((!Thread.currentThread().isInterrupted())&& ((line = connection.getInputStream().readLine()) != null)) {show(line);}} catch (IOException e) {} finally {if (connection != null)connection.close();}}}

输出结果：
