AndroidViewClient不显示id

Question

我一直在玩AndroidViewClient一段时间，但是我不明白为什么这个扩展在运行dump.py示例时不会显示视图的id。我的设备在API 16之上。有什么问题吗？

我得到了这样的输出，但是我也不知道为什么它不能说出视图的名字.

android.widget.FrameLayout id/no_id/1
   android.widget.LinearLayout id/no_id/2
      android.widget.FrameLayout id/no_id/3
         android.widget.RelativeLayout id/no_id/4
            android.widget.Button id/no_id/5 New Jersey
            android.widget.Button id/no_id/6 New York
            android.widget.Button id/no_id/7 New Castle
            android.widget.Button id/no_id/8 New Berg
            android.widget.Button id/no_id/9 New Class

错误：

Answer 1

如果设备的API级别是>= 16，则AndroidViewClient使用的默认后端是UiAutomator，它不显示If。为了提供额外的帮助，AndroidViewClient为视图分配了唯一的in，这就是dump.py在您的例子中所展示的。

​

​

通过向ViewServer提供相应的命令行选项，可以强制使用dump.py后端。

$ dmup.py --force-view-server-use

你会得到视图ID的。
