【adb 命令--进阶篇】

adb 连接设备的常用命令和DOS常用命令（2021-02-10更新 --基础篇）

一：获取控件属性

1：获取当前顶层activity 的界面元素，包含控件属性,并且可直接从输入流中读取：

private void getViewElements() throws IOException {
   Process p = Runtime.getRuntime().exec("adb shell uiautomator dump --compressed && cat /sdcard/window_dump.xml");
    //取得命令结果的输出流
    InputStream in = p.getInputStream();
    //用一个读输出流类去读
    InputStreamReader isr = new InputStreamReader(in);
    //用缓冲器读行
    BufferedReader br = new BufferedReader(isr);
    String line = null;
    StringBuilder sb = new StringBuilder();
    //直到读完为止
    while ((line = br.readLine()) != null) {
      System.out.println("ypktest=>>" + line);
      sb.append(line);
    }
  }

输入流读取的内容：

2：获取当前顶层activity 的界面元素，包含控件属性，读取输入流，包含文件存储路径。

private void getViewElements() throws IOException {
    Process p = Runtime.getRuntime().exec("adb shell uiautomator dump");
    //取得命令结果的输出流
    InputStream in = p.getInputStream();
    //用一个读输出流类去读
    InputStreamReader isr = new InputStreamReader(in);
    //用缓冲器读行
    BufferedReader br = new BufferedReader(isr);
    String line = null;
    StringBuilder sb = new StringBuilder();
    //直到读完为止
    while ((line = br.readLine()) != null) {
      System.out.println("ypktest=>>" + line);
      sb.append(line);
    }
  }

输入流读取的内容：

去该路径下会有window_dump.xml 文件，用IE浏览器打开效果：

3：获取当前顶层activity 的界面元素。未发现其实际用途。输入流不包含控件属性。

private void getViewElements() throws IOException {
    /Process p = Runtime.getRuntime().exec("adb shell dumpsys activity top");
    //取得命令结果的输出流
    InputStream in = p.getInputStream();
    //用一个读输出流类去读
    InputStreamReader isr = new InputStreamReader(in);
    //用缓冲器读行
    BufferedReader br = new BufferedReader(isr);
    String line = null;
    StringBuilder sb = new StringBuilder();
    //直到读完为止
    while ((line = br.readLine()) != null) {
      System.out.println("ypktest=>>" + line);
      sb.append(line);
    }
  }

输入流读取的内容：

二：解析控件数据
