不要在Android的Application对象中缓存数据!
在Androidlibrary中不能使用switch-case语句访问资源ID的原因分析及解决方案
禁止RatingBar选择或改变
加这个属性,android:isIndicator="true"
setDuplicateParentStateEnabled子控件获得父控件的状态,对应android:duplicateParentState
setAddStatesFromChildren同上相反,对应android:addStatesFromChildren
这两个属性不能同时设置,同时设置会产生异常
Android开发最佳实践

你还在写一堆的findViewById()吗?
自定义一个方法:
public <T T extends View> T $(int viewID) { return (T) findViewById(viewID); }
然后不管是什么类型的View,直接一个$方法搞定,类似JQuery
Android中strings.xml占位符
<stringname="data">整数型:%1$d,浮点型:%2$.3f,字符串:%3$s</string>
其中%后面是占位符的位置,从1开始,
$后面是填充数据的类型
%d:表示整数型;
%f:表示浮点型,其中f前面的.3表示小数的位数
%s:表示字符串
String data = getResources().getString(R.string.data); data = String.format(data, 100, 100.333, "2014-02-26"); //整数型:100,浮点型:100.333,字符串:2014-02-26
动态设置全屏,退出全屏
/**设置全屏**/ WindowManager.LayoutParams params = getWindow().getAttributes(); params.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN; getWindow().setAttributes(params); getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); /**退出全屏**/ WindowManager.LayoutParams params = getWindow().getAttributes(); params.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN); getWindow().setAttributes(params); getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

UrlQuerySanitizer
一个很方便用来处理url链接的工具类,之前开发过程中遇到需要处理支付宝网页url,获取里面post参数,当时使用String的各种接口进行处理,如果用UrlQuerySanitizer的话就简单多了。比如现在有个Url=http://example.com/?name=Mark,我们使用UrlQuerySanitizer拿到name的值:
Simpleexample:
UrlQuerySanitizer sanitizer = new UrlQuerySanitizer(); sanitizer.setAllowUnregisteredParamaters(true); sanitizer.parseUrl("http://example.com/?name=Joe+User"); String name = sanitizer.getValue("name")); // name now contains "Joe_User" Register ValueSanitizers to customize the way individual parameters are sanitized:
UrlQuerySanitizer sanitizer = new UrlQuerySanitizer(); sanitizer.registerParamater("name", UrlQuerySanitizer.createSpaceLegal()); sanitizer.parseUrl("http://example.com/?name=Joe+User"); String name = sanitizer.getValue("name")); // name now contains "Joe User". (The string is first decoded, which // converts the '+' to a ' '. Then the string is sanitized, which // converts the ' ' to an '_'. (The ' ' is converted because the default unregistered parameter sanitizer does not allow any special characters, and ' ' is a special character.)
/** * 获得url中对应key的参数值(value) * * @param url * @param key * @return */ public String getParameter(String url, String key) { if (!TextUtils.isEmpty(url)) { UrlQuerySanitizer sanitizer = new UrlQuerySanitizer(url); sanitizer.setAllowUnregisteredParamaters(true); return sanitizer.getValue(key); } return null; }
PhoneNumberUtils
publicstaticStringformatNumber(StringphoneNumber,StringdefaultCountryIso)
PhoneNumverUtils提供了一系列方法用来格式化电话号码
String num = "031185203009"; PhoneNumberUtils util = new PhoneNumberUtils(); String numFormated = util.formatNumber(num,"CN");
numFormated=0311-8520-3009
