AVD 的鍵盤輸入

進 Eclipse 點 Window/Android Virtual Device Manager
編輯虛擬機器之 Keyboard 設定
勾選 Hardware keyboard present：使用開發機器的實體鍵盤
  可方便輸入英文和符號，但無法使用中文
  原本要按 Shift 的要加按 Alt
取消勾選 Hardware keyboard present：使用Android的鍵盤
  可安裝中文輸入法，但很難操作

下載adnroid注音輸入法

安裝輸入法
C:\eclipse4_64\android-sdk-windows\platform-tools>adb install ZhuYinIME_2010030801.apk
1101 KB/s (1012516 bytes in 0.897s)
        pkg: /data/local/tmp/ZhuYinIME_2010030801.apk
Success

設定輸入法
設定/語言與輸入設定/勾選注音輸入法

點選 edittext 時還是出現英文鍵盤
常按英文鍵盤的空白鍵，此時跳出輸入法切換，選擇注音輸入法
若要回復成英文鍵盤，還是要回設定取消勾選注音輸入法

adnroid adb

查詢連接的裝置

測試網路
C:\eclipse4_64\android-sdk-windows\platform-tools>adb shell ping -c 3 localhost
