1 uiautomatorviewer簡介

• 之前文章說明了Appium Inspector的定位使用方法；
• uiautomatorviewer是另一種定位工具；
• uiautomatorviewer是android-sdk自帶的元素定位工具；
• 它是通過截屏分析XML布局文件方式，來提供控件信息的查看服務。

2 uiautomatorviewer特點

• uiautomatorviewer和Appium Inspector有著明顯的區(qū)別；
• Appium Inspector功能相對比較強大；
• 而uiautomatorviewer只能用于安卓系統(tǒng)；
• 另外uiautomatorviewer只能用于元素定位，不支持通過該工具操作APP，也不支持錄制功能等。

3 uiautomatorviewer啟用

• uiautomatorviewer位于SDK目錄下的tools\目錄下；
• 比如我的是：D:\android-sdk-windows\tools：
  
• 雙擊uiautomatorviewer.bat進行啟動即可：
  

4 Work Bar

• Work Bar即工作欄，工作欄中有4個按鈕，如圖所示：
  

• 從左到右依次為：

• 其中4保存時將保存兩個文件，一個是圖片，一個是.uix文件；
  
• 可以查看圖片顯示：
  
• 也可以查看XML格式內容：

• 其中2會顯示全部布局；
• 其中3只顯示部分有用的控件布局。

5 Screenshot

• screenshot是截圖區(qū)域，在圖中的左側部分；
• 主要是顯示當前屏幕的布局圖片：
  

6 控件布局

• 控件布局內容主要在右上方顯示，以XML格式展示；
  

7 控件屬性

• 控件屬性顯示在右下方，當點擊一個控件時，將會在這顯示其屬性信息：
  

8 連接設備

• 直接點擊工作欄中的第二個或第三個按鈕即可連接到設備；
• 我們這里點擊的是第二個按鈕Device Screenshot；
  

9 Error while obtaining UI問題排查

• 當我們點擊第二個按鈕Device Screenshot時出現以下界面：
  
• 這個說明報錯了，沒有連接上，那我們看下詳細信息，點擊【Details】：

Error while obtaining UI hierarchy XML file: com.android.ddmlib.SyncException: Remote object doesn't exist!

• 大概意思是Remote object doesn't exist，就是說已經存在了一個連接，那我們就需要斷開已經連接的才行；
• 我們檢查發(fā)現使用了Appium-Inspector已經連接了，我們點擊【×】斷開這個會話連接：

• 重新再連接就可以使用uiautomatorviewer連接上了。
