【转】edittext设置点击链接

I put some ClickableSpan in EditText, unfortunately, that spans are still not clickable. When I click them, the only thing happened when I tap the clickablespan is the text cursor(selection, position, whatever you call it is) been set to that position.

After some search, I find out: I have to do this to make the span clickable?

setMovementMethod(LinkMovementMethod.getInstance());

After this, I do can click the ClickableSpan, but a new problem appear:

I can't do cursor selecting anymore, the cursor disappeared!

After a lot of searching and analyzing, I decide to make my own MovementMethod, which support both cursor selecting and span clicking. It's easy, the onTouchEvent() method is copied from android 1.5-r4 source code.

Here it goes:

package my.handrite.text.method;

import android.text.Layout;
import android.text.Selection;

public class LinkArrowKeyMovementMethod extends ArrowKeyMovementMethod {
private static LinkArrowKeyMovementMethod mInstance;

@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);

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.setSelection(buffer,
                                          buffer.getSpanStart(link[0]),
                                          buffer.getSpanEnd(link[0]));
               }

return true;
           } else {
               Selection.removeSelection(buffer);
           }
       }

return super.onTouchEvent(widget, buffer, event);
}
@Override
public String toString(){
return "my.handrite.text.method.ClickableArrowKeyMovementMethod";
}
   public static MovementMethod getInstance() {
       if (mInstance == null)
           mInstance = new LinkArrowKeyMovementMethod();

return mInstance;
   }
}
