Hadoop 2.x属性修改

Hadoop自升级到2.x版本之后，有很多属性的名称已经被遗弃了，虽然这些被遗弃的属性名称目前还可以用，但是这里还是建议用新的属性名，主要遗弃的属性名称主要见下面表格： 已经被遗弃属性的名称 新的属性名称 create.empty.dir.if.nonexist mapreduce.jobcontrol.createdir.ifnotexist dfs.access.time.precision

andorid 修改字体一文搞定

本文首发于公众号“AntDream”，欢迎微信搜索“AntDream”或扫描文章底部二维码关注，和我一起每天进步一点点 替换字体也是一个比较常见的需求，一般分几种情况。实现起来也不麻烦，这里简单记录下 全局替换字体 步骤1 assets目录下拷贝字体文件 步骤2 application中替换默认字体 在Application的onCreate方法中增加替换方法 /** * 设置自定义字体 * * @param context * @param staticTypefaceFieldName 需要替换的系统字体样式 * @param fontAssetName 替换后的字体样式 */ public static void setDefaultFont(Context context, String staticTypefaceFieldName, String fontAssetName) { // 根据路径得到Typeface Typeface regular = Typeface.createFromAsset(context.getAssets(), fontAssetName); // 设置全局字体样式 replaceFont(staticTypefaceFieldName, regular); } private static void replaceFont(String staticTypefaceFieldName, final Typeface newTypeface) { try { final Field staticField = Typeface.class.getDeclaredField(staticTypefaceFieldName); staticField.setAccessible(true); //替换系统字体样式 staticField.set(null, newTypeface); } catch (NoSuchFieldException e) { e.printStackTrace(); } catch (IllegalAccessException e) { e.printStackTrace(); } } 步骤3：新增主题Theme，并在AndroidManifest文件中注册 新增主题 <style name="YourTheme" parent="AppTheme.Base"> <item name="android:typeface" >serif</item> </style> 在AndroidManifest.xml文件中设置主题 <application xmlns:tools="http://schemas.android.com/tools" ... android:theme="@style/YourTheme" tools:replace="android:theme"> ... </application> 替换某些布局中的字体，也就是局部替换 步骤1：在res目录下新建font目录，拷贝字体文件 步骤2: 代码中替换 TextView textView = (TextView) findViewById(R.id.textView_font); Typeface typeface = ResourcesCompat.getFont(this, R.font.myfont); textView.setTypeface(typeface); 欢迎关注我的微信公众号，和我一起每天进步一点点！
