I'm using clickable span in a textView to enable only part of the text to be clickable. It works fine except that the textView is scrolling down and that's something I don't want. It happens because I use LinkMovementMethod that scrolls if needed. Is there anyway to cancel the scrolling?
SpannableString ss = "My text [click area] end."
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(View textView) {
// My click action
}
};
// Set the span
String fromString = "text";
int startClickPos = ss.toString().indexOf(fromString)+fromString.length()+1;
int endCickPos=startClickPos+ 12;
ss.setSpan(clickableSpan, startClickPos, endCickPos, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.setText(ss);
textView.setMovementMethod(LinkMovementMethod.getInstance());
I am using this code to disable scrolling for TextView with clickableSpan.
public class LinkMovementMethodOverride implements View.OnTouchListener{
@Override
public boolean onTouch(View v, MotionEvent event) {
TextView widget = (TextView) v;
Object text = widget.getText();
if (text instanceof Spanned) {
Spanned buffer = (Spanned) text;
int action = event.getAction();
if (action == MotionEvent.ACTION_UP
|| action == MotionEvent.ACTION_DOWN) {
int x = (int) event.getX();
int y = (int) event.getY();
x -= widget.getTotalPaddingLeft();
y -= widget.getTotalPaddingTop();
x += widget.getScrollX();
y += widget.getScrollY();
Layout layout = widget.getLayout();
int line = layout.getLineForVertical(y);
int off = layout.getOffsetForHorizontal(line, x);
ClickableSpan[] link = buffer.getSpans(off, off,
ClickableSpan.class);
if (link.length != 0) {
if (action == MotionEvent.ACTION_UP) {
link[0].onClick(widget);
} else if (action == MotionEvent.ACTION_DOWN) {
// Selection only works on Spannable text. In our case setSelection doesn't work on spanned text
//Selection.setSelection(buffer, buffer.getSpanStart(link[0]), buffer.getSpanEnd(link[0]));
}
return true;
}
}
}
return false;
}
}
After that apply it to the target textview as touch listener: -
textview.setOnTouchListener(new LinkMovementMethodOverride());
