ClickableSpan和TouchableSpan：

我是这样做的，
以下是我的ClickableSpan.java和TouchableSpan.java代码：

1. import android.text.TextPaint;
2. import android.text.style.CharacterStyle;
3. import android.text.style.UpdateAppearance;
4. import android.view.MotionEvent;
5. import android.view.View;
7. /**
8. * If an object of this type is attached to the text of a TextView
9. * with a movement method of LinkTouchMovementMethod, the affected spans of
10. * text can be selected. If touched, the {@link #onTouch} method will
11. * be called.
12. */
13. public abstract class TouchableSpan extends CharacterStyle implements UpdateAppearance {
15. /**
16. * Performs the touch action associated with this span.
17. * @return
18. */
19. public abstract boolean onTouch(View widget, MotionEvent m);
21. /**
22. * Could make the text underlined or change link color.
23. */
24. @Override
25. public abstract void updateDrawState(TextPaint ds);
27. }

复制代码
然后,我让LinkTouchMovementMethod类继承LinkMovementMethod类；onTouchEvent()方法中，onClick变成了onTouch：

1. import android.widget.TextView;
3. public class LinkTouchMovementMethod extends LinkMovementMethod
4. {
6. @Override
7. public boolean onTouchEvent(TextView widget, Spannable buffer,
8. MotionEvent event) {
9. int action = event.getAction();
11. if (action == MotionEvent.ACTION_UP ||
12. action == MotionEvent.ACTION_DOWN) {
13. int x = (int) event.getX();
14. int y = (int) event.getY();
16. x -= widget.getTotalPaddingLeft();
17. y -= widget.getTotalPaddingTop();
19. x += widget.getScrollX();
20. y += widget.getScrollY();
22. Layout layout = widget.getLayout();
23. int line = layout.getLineForVertical(y);
24. int off = layout.getOffsetForHorizontal(line, x);
26. TouchableSpan[] link = buffer.getSpans(off, off, TouchableSpan.class);
28. if (link.length != 0) {
29. if (action == MotionEvent.ACTION_UP) {
30. link[0].onTouch(widget,event); //////// CHANGED HERE
31. } else if (action == MotionEvent.ACTION_DOWN) {
32. link[0].onTouch(widget,event); //////// ADDED THIS
33. Selection.setSelection(buffer,
34. buffer.getSpanStart(link[0]),
35. buffer.getSpanEnd(link[0]));
36. }
38. return true;
39. } else {
40. Selection.removeSelection(buffer);
41. }
42. }
44. return super.onTouchEvent(widget, buffer, event);
45. }
47. }

复制代码
然后,在你的MovementMethod中做适当的更改:

1. TextView tv = (TextView) findViewById(R.id.tv);
2. tv.setMovementMethod(new LinkTouchMovementMethod());
4. Now to show the text:
5. touchableSpan = new TouchableSpan() {
7. public boolean onTouch(View widget, MotionEvent m) {
9. ...
11. }
13. public void updateDrawState(TextPaint ds) {
14. ds.setUnderlineText(false);
15. ds.setAntiAlias(true);
16. }
18. };
20. String rv = "Text to span";
22. text = new SpannableString(rv);
24. text.setSpan(touchableSpan, begin, end, 0);
26. tv.setText(text, BufferType.SPANNABLE);
