Android 4.2中添加解鎖項

在Android 4.2中系統默認解鎖是滑動到任意位置後就會解鎖，如果想添加解鎖內容需要修改如下代碼：

1.frameworks/base/core/res/res/layout/keyguard_glow_pad_view.xml

[html]   
-    prvandroid:targetDrawables="@array/lockscreen_targets_unlock_only" 
-    prvandroid:targetDescriptions="@array/lockscreen_target_descriptions_unlock_only" 
+    prvandroid:targetDrawables="@array/lockscreen_targets_with_camera" 
+    prvandroid:targetDescriptions="@array/lockscreen_target_descriptions_with_camera" 

 
-    prvandroid:targetDrawables="@array/lockscreen_targets_unlock_only"
-    prvandroid:targetDescriptions="@array/lockscreen_target_descriptions_unlock_only"
+    prvandroid:targetDrawables="@array/lockscreen_targets_with_camera"
+    prvandroid:targetDescriptions="@array/lockscreen_target_descriptions_with_camera"

這樣在解鎖時就會默認增加相機以及google搜索。

2.如果想要添加自定義解鎖內容，只需要按照Android原生模板進行添加或者修改即可。
