Expand ClickableSpan Touch Area

Question

I have a TextView in which I set the HTML text. There are many links in this text. When you click a link, this does not always call the onClick method. So, I'm trying to expand the scope of ClickableSpan so that it is always responsive.

int start = strBuilder.getSpanStart(span); int end = strBuilder.getSpanEnd(span); int flags = strBuilder.getSpanFlags(span); final ClickableSpan clickable = new ClickableSpan() { public void onClick(View view) { getTouchActions(span.getURL()); } }; strBuilder.setSpan(clickable, start, end, flags); strBuilder.removeSpan(span);

CustomMovementMethod should extend ScrollingMovementMethod and override the onTouchEvent method. To add extra space, you must define it in your dimensions and use it at the beginning / end.

 @Override public boolean onTouchEvent(TextView widget, Spannable buffer, MotionEvent event) { 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); int startSpan = off - context.getResources().getDimension(R.dimen.extra_space_start); int endSpan = off + context.getResources().getDimension(R.dimen.extra_space_end); ClickableSpan[] link = buffer.getSpans(startSpan, endSpan, ClickableSpan.class); if (link.length != 0) { if (action == MotionEvent.ACTION_UP) { link[0].onClick(widget); } else if (action == MotionEvent.ACTION_DOWN) { Selection.setSelection(buffer, buffer.getSpanStart(link[0]), buffer.getSpanEnd(link[0])); } return true; } else { Selection.removeSelection(buffer); } } return super.onTouchEvent(widget, buffer, event); 

}

You can invoke your custom link movement as follows:

 textView.setMovementMethod(new CustomLinkMovementMethod(context)); textView.setLinksClickable(true);
