26.             Index.getInstance(  
27.                     getActivity().getApplicationContext()).updateFromClassNameResource(  
28.                             DevelopmentSettings.class.getName(), true, true);  
29.   
30.         } else if (mDevHitCountdown > 0  
31.                 && mDevHitCountdown < (TAPS_TO_BE_A_DEVELOPER-2)) {  
32.             if (mDevHitToast != null) {  
33.                 mDevHitToast.cancel();  
34.             }  
35.             mDevHitToast = Toast.makeText(getActivity(), getResources().getQuantityString(  
36.                     R.plurals.show_dev_countdown, mDevHitCountdown, mDevHitCountdown),  
37.                     Toast.LENGTH_SHORT);  
38.             mDevHitToast.show();  
39.         }  
40.         } else if (mDevHitCountdown < 0) { //点击完7次之后显示  
41.             if (mDevHitToast != null) {  
42.                 mDevHitToast.cancel();  
43.             }  
44.             mDevHitToast = Toast.makeText(getActivity(), R.string.show_dev_already,

46.             mDevHitToast.show();  
47.         }  
48.     }  
49. ......  
50. }  

而默认开机是否显示由变量showDev控制
packages\apps\Settings\src\com\android\settings\SettingsActivity.java

[cpp]  view plain  copy

 

1. private void updateTilesList(List<DashboardCategory> target) {  
2.     final boolean showDev = mDevelopmentPreferences.getBoolean(  
3.             DevelopmentSettings.PREF_SHOW,  
4.             android.os.Build.TYPE.equals("eng"));    //因此eng才返回true  
5. ......  
6.     } else if (id == R.id.development_settings) {  
7.         if (!showDev || um.hasUserRestriction(  
8.                 UserManager.DISALLOW_DEBUGGING_FEATURES)) {  
9.             removeTile = true;    //showDev为false则不显示  
10.         }  
11.     }  
12. }
