仅作记录代码用,功能未能测试成功,在低版本上不存在 sHasPermanentMenuKey 属性,会出现 java.lang.NoSuchFieldException: sHasPermanentMenuKey 异常
try { ViewConfiguration config = ViewConfiguration.get(this); Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey"); if (menuKeyField != null) { menuKeyField.setAccessible(true); menuKeyField.setBoolean(config, false); } } catch (Exception e) { e.printStackTrace(); }
