android6.0中全屏處理（禁止通知欄下滑）

在android6.0項目中，因需要做全屏處理，故在此整理出全屏時禁止通知欄下滑的代碼，希望可以幫助到也有如此困惑的人。

    1.在onCreate中添加：//設置全屏

        requestWindowFeature(Window.FEATURE_NO_TITLE);

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

WindowManager.LayoutParams.FLAG_FULLSCREEN);

    2.在onResume()函數(shù)中添加：//進入activity時，設置禁止通知欄不滑

        Settings.System.putInt(this.getContentResolver(),

Settings.System.FULL_SCREEN_EXPAND_STATUSBAR, 0);

    3.在onPause()函數(shù)中添加：//離開activity時，恢復通知欄下滑

        Settings.System.putInt(this.getContentResolver(),

Settings.System.FULL_SCREEN_EXPAND_STATUSBAR, 1);

    4.在frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.javar的updateSystemUiViSiBilityLw()函數(shù)中添加：//此代碼我添加在tmpVisibility = updateLightStatusBarLw(tmpVisibility);后，有可能其它人的項目代碼有改動，在需要此代碼的請酌情添加至合適位置。

        final int visibility;

         if(Settings.System.getInt(mContext.getContentResolver(),

            Settings.System.FULL_SCREEN_EXPAND_STATUSBAR, 1) == 0) {

             visibility = tmpVisibility;

          }else{

             visibility = updateSystemBarsLw(win, mLastSystemUiFlags,tmpVisibility);

        }

    5.在frameworks/base/core/java/android/provider/Settings.java中添加://定義FULL_SCREEN_EXPAND_STATUSBAR

        public static final String FULL_SCREEN_EXPAND_STATUSBAR = "full_screen_expand_statusbar";

    6.在frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/SettingsProvider.java中添加：//與上方onPause()中意義基本相同，未深究

      systemSettings.insertSettingLocked(Settings.System.FULL_SCREEN_EXPAND_STATUSBAR, "1",SettingsState.SYSTEM_PACKAGE_NAME);

說明：為保證添加了FULL_SCREEN_EXPAND_STATUSBAR不會給系統(tǒng)其它地方造成影響，上述6處的代碼請完整添加，否則有可能引起未知錯誤！
