我一直在从字符串数组中获取每个单词这是部分代码:
String wordS[] = mystring.split(" ");
然后我想把每个单词储存在wordS[]中,并把储存在wordS[]中的每个单词转换成字符串
示例:
mystring = " hi everyone how are you "
String[] wordS = mystring.split(" ");
String word1 = word1 from wordS[](Hi)
String word2 = word2 from wordS[](eeryone)
String word3 = word3 from ... for max 20 strings wich contain 1 word
编辑:
这是我的代码:
String txt = tv.getText().toString();
Pattern mat = Pattern.compile("(?<=\^)([^0-9]+[0-9]+)|([^^0-9]+$)");
Matcher m = mat.matcher(txt);
while (m.find())
{
String match = m.group();
String n= match.replaceFirst("^[^0-9]+", "");
if (n.length() >= 1)
{
int i = Integer.parseInt(n);
switch (i)
{
case 0:
s = "<font color ='black'>";
break;
case 1:
s = "<font color ='red'>";
break;
case 2:
String green = "#7CFC00";
s = "<font color ='" + green + "'>";
break;
case 3:
String gold ="#FFD700";
s = "<font color ='" + gold + "' >";
break;
case 4:
s = "<font color ='blue' >";
break;
case 5:
String cyan ="#00FFFF";
s = "<font color ='" + cyan + "' >";
break;
case 6:
String magenta ="#FF00FF";
s = "<font color ='" + magenta + "' >";
break;
case 7:
String peru ="#FFC0CB";
s = "<font color ='" + peru + "' >";
break;
case 8:
String gray ="#808080";
s = "<font color ='" + gray + "' >";
break;
case 9:
String orange ="#FFA500";
s = "<font color ='" + orange + "' >";
break;
default:
s = "<font color ='white'>";
}
String replace = match.replaceFirst("[0-9]+$", "");
String[] wordS = replace.split(" ");
showf.setText(Html.fromHtml(s + "" + replace + "</font>"));
}
else
{
showf.setText(match.replaceFirst("[0-9]+$", ""));
}
}
此函数用于将字符串的一部分着色,它将检测用户是否键入^test2<--"2"=指定颜色的int。如果y键入:^blablabla5,它将返回青色文本颜色。工作正常,但现在我想更新我的函数示例,如果我键入:^word4^secondword6我的函数只返回最后一个单词,但我希望用户键入所有单词你有个主意吗?
纠正字符串数组的用法
String [] words = mystring.split(" ");
然后使用索引获取每个字符串。例如:words[i],其中i
是索引。因此,您可以只使用words[0]
、words[1]
等,而不必为每个声明单独的String
,而无需声明附加变量。它与执行以下操作相同:
String s1 = words[0];
String s2 = words[1];
...
关于在TextView
中显示,不清楚您想在TextView
中显示什么。
TextView text = (TextView) findViewById(Your_Textviw_ID); // you might have declared it in an XML somewhere.
text.setText(the_sring_you_want_to_set_it_to);
