Android ClickableSpan get text onClick()
try this:
public class LoremIpsumSpan extends ClickableSpan {
@Override
public void onClick(View widget) {
// TODO add check if widget instanceof TextView
TextView tv = (TextView) widget;
// TODO add check if tv.getText() instanceof Spanned
Spanned s = (Spanned) tv.getText();
int start = s.getSpanStart(this);
int end = s.getSpanEnd(this);
Log.d(TAG, "onClick [" + s.subSequence(start, end) + "]");
}
}
A little simpler, could also pass a model reference if necessary.
public class SpecialClickableSpan extends ClickableSpan {
String text;
public SpecialClickableSpan(String text){
super();
this.text = text;
}
@Override
public void onClick(View widget) {
Log.d(TAG, "onClick [" + text + "]");
}
}
Then call new SpecialClickableSpan("My Text")
Edited: previous code was wrong, this works
// make "dolor" (characters 12 to 17) display a toast message when touched
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(View view) {
TextView textView = (TextView) view;
CharSequence charSequence = textView.getText();
if (charSequence instanceof Spannable) {
Spannable spannableText = (Spannable)charSequence;
ClickableSpan[] spans = spannableText.getSpans(0, textView.length(), ClickableSpan.class);
for (ClickableSpan span : spans) {
int start = spannableText.getSpanStart(span);
int end = spannableText.getSpanEnd(span);
Toast.makeText(MainActivity.this, charSequence.subSequence(start, end), Toast.LENGTH_LONG).show();
}
}
}
};
