Android开发_字符串处理类-TextUtils类
对于字符串处理Android为我们提供了一个简单实用的TextUtils类,如果处理比较简单的内容不用去思考正则表达式不妨试试这个在android.text.TextUtils的类,主要的功能如下: 是否为空字符 static boolean isEmpty(CharSequence str)
拆分字符串 public static String[] split (String text, String expression) ,Android开发网提示大家仔细看例子如下 String.split() returns [''] when the string to be split is empty. This returns []. This does not remove any empty strings from the result. For example split("a,", "," ) returns {"a", ""}.
拆分字符串使用正则 public static String[] split (String text, Pattern pattern)
确定大小写是否有效在当前位置的文本TextUtils.getCapsMode(CharSequence cs, int off, int reqModes)
使用HTML编码这个字符串 static String TextUtils.htmlEncode(String s)
<span style="color:#ff0000;">if (!TextUtils.isEmpty(spUtil.getUserId())) {</span> Intent intent = new Intent(WelcomeActivity.this, MainActivity.class); startActivity(intent); } else { startActivity(new Intent(WelcomeActivity.this,
FirstSetActivity.class));
}
