本文介绍了如何用空格代替逗号,当我使用" MultiAutoCompleteTextView"的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我在做用MultiAutoCompleteTextView提示常用词一个简单的程序,当我
输入查询几个字母。
code:
ArrayAdapter<串GT;适配器=新ArrayAdapter<串GT;(
这个,
android.R.layout.simple_dropdown_item_1line,
元);
MultiAutoCompleteTextView的TextView =(MultiAutoCompleteTextView)findViewById(R.id.editText);
textView.setAdapter(适配器); textView.setTokenizer(新MultiAutoCompleteTextView.CommaTokenizer()); 私有String []元=新的String [] {
ABC,
A B C D,
ABCDE
ABCDEF
ABCDEFG
HIJ
HIJK
hijkl
hijklm
hijklmn
};
现在,当我输入'a'and选择ABCD,但结果成为ABCD。如何更换逗号空间?
感谢您!

公共类SpaceTokenizer实现分词{公众诠释findTokenStart(CharSequence的文字,INT光标){
INT I =光标;而(ⅰ大于0&放大器;&放大器;!text.charAt(I - 1)=''){
一世 - ;
}
而(ⅰ&所述;光标&放大器;&放大器; text.charAt(ⅰ)==''){
我++;
}返回我;
}公众诠释findTokenEnd(CharSequence的文字,INT光标){
INT I =光标;
INT LEN = text.length();而(I< LEN){
如果(text.charAt(ⅰ)==''){
返回我;
}其他{
我++;
}
}返回LEN;
}公众的CharSequence terminateToken(CharSequence的文字){
INT I = text.length();而(ⅰ大于0&放大器;&放大器; text.charAt(I - 1)==''){
一世 - ;
}如果(ⅰ大于0&放大器;&放大器; text.charAt(I - 1)==''){
返回文本;
}其他{
如果(文本的instanceof跨区){
SpannableString SP =新SpannableString(文字+);
TextUtils.copySpansFrom((跨区)文字,0,text.length()
Object.class,SP,0);
返回SP;
}其他{
返回文字+;
}
}
}
}
I'm doing a simple program using "MultiAutoCompleteTextView" to prompt the common words when I
inputing several letters.
code:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_dropdown_item_1line,
ary);
MultiAutoCompleteTextView textView = (MultiAutoCompleteTextView) findViewById(R.id.editText);
textView.setAdapter(adapter);
textView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
private String[] ary = new String[] {
"abc",
"abcd",
"abcde",
"abcdef",
"abcdefg",
"hij",
"hijk",
"hijkl",
"hijklm",
"hijklmn",
};
Now,when I input 'a'and choose "abcd" but the result become to "abcd,". How to replace the comma to a space?
Thank you!
解决方案
public class SpaceTokenizer implements Tokenizer {
public int findTokenStart(CharSequence text, int cursor) {
int i = cursor;
while (i > 0 && text.charAt(i - 1) != ' ') {
i--;
}
while (i < cursor && text.charAt(i) == ' ') {
i++;
}
return i;
}
public int findTokenEnd(CharSequence text, int cursor) {
int i = cursor;
int len = text.length();
while (i < len) {
if (text.charAt(i) == ' ') {
return i;
} else {
i++;
}
}
return len;
}
public CharSequence terminateToken(CharSequence text) {
int i = text.length();
while (i > 0 && text.charAt(i - 1) == ' ') {
i--;
}
if (i > 0 && text.charAt(i - 1) == ' ') {
return text;
} else {
if (text instanceof Spanned) {
SpannableString sp = new SpannableString(text + " ");
TextUtils.copySpansFrom((Spanned) text, 0, text.length(),
Object.class, sp, 0);
return sp;
} else {
return text + " ";
}
}
}
}
