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 UPDATE
Appiot----------------FOCUS UPDATE
Appiot----------------LIST UPDATE
Appiot----------------LIST UPDATE
Appiot----------------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：

Appiot----------------LIST UPDATE
Appiot----------------42180858 com.sina.weibopro/com.sina.weibopro.DetailWeiboActivity
Appiot----------------FOCUS UPDATE
Appiot----------------LIST UPDATE
Appiot----------------LIST UPDATE
Appiot----------------LIST UPDATE

ViewServer接受hierarchyviewer的命令
