1、

	/*** 收起状态栏* * @param context*            上下文对象* @return 成功收起状态栏返回true,否则返回false*/public static boolean collapseStatusBar(Context context) {Object statusbarService = context.getSystemService("statusbar");if (statusbarService == null) {return false;}try {Class<?> statusBarManager = Class.forName("android.app.StatusBarManager");if (statusBarManager == null) {return false;}Method collapseMethod;if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {collapseMethod = statusBarManager.getMethod("collapsePanels");} else {collapseMethod = statusBarManager.getMethod("collapse");}if (collapseMethod == null) {return false;}collapseMethod.invoke(statusbarService);} catch (Exception e) {e.printStackTrace();return false;}return true;}

2、

/*** 展开状态栏* * @param context*            上下文对象* @return 成功展开状态栏返回true,否则返回false*/public static boolean expandStatusBar(Context context) {Object statusbarService = context.getSystemService("statusbar");if (statusbarService == null) {return false;}try {Class<?> statusBarManager = Class.forName("android.app.StatusBarManager");if (statusBarManager == null) {return false;}Method expandMethod;if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {expandMethod = statusBarManager.getMethod("expandNotificationsPanel");} else {expandMethod = statusBarManager.getMethod("expand");}if (expandMethod == null) {return false;}expandMethod.invoke(statusbarService);} catch (Exception e) {e.printStackTrace();return false;}return true;}

3、

/*** 获取状态栏高度* * @param context*            上下文对象* @return 状态栏高度*/public static int getStatusBarHeight(Context context) {Class<?> c = null;Object obj = null;Field field = null;int x = 0, statusBarHeight = 0;try {c = Class.forName("com.android.internal.R$dimen");obj = c.newInstance();field = c.getField("status_bar_height");x = Integer.parseInt(field.get(obj).toString());statusBarHeight = context.getResources().getDimensionPixelSize(x);} catch (Exception e) {e.printStackTrace();}return statusBarHeight;}

4、

/*** 切换到全屏* * @param activity*            activity实例*/public static void switchToFullScreen(Activity activity) {activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);}

5、

	/*** 切换到非全屏* * @param activity*            activity实例*/public static void switchToNoFullScreen(Activity activity) {activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);}

6、

	/*** 开启显示触摸位置功能* * @param context*            上下文对象*/public static void showTouchLocation(Context context) {android.provider.Settings.System.putInt(context.getContentResolver(),"show_touches", 1);}

7、

	/*** 关闭显示触摸位置功能* * @param context*            上下文对象*/public static void hideTouchLocation(Context context) {android.provider.Settings.System.putInt(context.getContentResolver(),"show_touches", 0);}
