TextView只響應鏈接的觸摸事件。基於 https://stackoverflow.com/a/7327332/1768722
public class AutoLinkTextView extends TextView {
public AutoLinkTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public AutoLinkTextView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public AutoLinkTextView(Context context) {
super(context);
init();
}
private void init() {
this.setAutoLinkMask(Linkify.ALL);
}
/**
* @Linkify applies to a movementMethod to the textView @LinkMovementMethod.
* That movement method thought it implements a scrolling
* vertically method it overrides any other scrolling method the
* parent has.
*
* Although touchEvent can be dispached to the parent, the specific
* parent ScrollView needed the whole sequence ACTION_DOWN ,
* ACTION_MOVE, ACTION_UP to perform (sweep detection). So the
* solution to this problem is after applying @Linkify we need to
* remove the textView's scrolling method and handle the @LinkMovementMethod
* link detection action in onTouchEvent of the textView.

這可能是太晚了..但我有同樣的問題,發現這個沒有答案帖子。 :) –
