I was positioned to the problem,when i let the textview setMovementMethod,the probrom occurred.can u give me some suggestion
i solve it. if someone has the same problem,it maybe can help u. when u setMovementMethod for textview,u also let it scroll. u need prohibit it,so overridde the LinkMovementMethod like this:
public class NoScrollLinkMovementMethod implements 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;
}
then, setOnTouchListener replace setMovementMethod, it works for me.
