我有一个为textview构建可点击标签的功能。它如下:
private CharSequence tagsBuilder(String text, String token) {
SpannableStringBuilder builtTags = new SpannableStringBuilder();
int start = 0, end = 0;
for(int i = 0; i < 5; i++) {
start = 0;
end = text.indexOf(token, 0);
try {
if(start < end) {
SpannableStringBuilder ssb = new SpannableStringBuilder(text.substring(start, end));
ssb.setSpan(new ClickableSpan() {
@Override
public void onClick(View v)
{
Log.i("DEBUGTAG", "Span clicked - " + ((TextView) v).getText());
}
}, start, end, 0);
builtTags.append(ssb);
builtTags.append(" ");
text = text.substring(end + 1);
}
} catch (IndexOutOfBoundsException e) {
break;
}
}
return builtTags;
}
我可以看到带有5个可单击的标签的textview。但问题是,为任何单击的标签打印的日志是textview的全文。
我在这里做错了吗?如何获取单击的单个标签的文本。
答案 0 :(得分:4)
您的日志行如下:
Log.i("DEBUGTAG", "Span clicked - " + ((TextView) v).getText());
记录TextView
的内容。所以......你得到了TextView
的文字。如果您想在那里获得token
,则必须将其复制到其中。
这是你可以尝试的东西:
private CharSequence tagsBuilder(String text, final String token) {
SpannableStringBuilder builtTags = new SpannableStringBuilder();
int start = 0, end = 0;
for(int i = 0; i < 5; i++) {
start = 0;
end = text.indexOf(token, 0);
try {
if(start < end) {
SpannableStringBuilder ssb = new SpannableStringBuilder(text.substring(start, end));
ssb.setSpan(new ClickableSpan() {
private String mText = token;
@Override
public void onClick(View v)
{
Log.i("DEBUGTAG", "Span clicked - " + mText);
}
}, start, end, 0);
builtTags.append(ssb);
builtTags.append(" ");
text = text.substring(end + 1);
}
} catch (IndexOutOfBoundsException e) {
break;
}
}
return builtTags;
}
