下面的代码是自定义clickspan
public class MyClickableSpan extends ClickableSpan {
private onTextClickListener mListener;
public MyClickableSpan(onTextClickListener listener) {
this.mListener = listener;
}
@Override
public void onClick(View widget) {
mListener.textClick(widget);
}
@Override
public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
mListener.setStyle(ds);
}
}下面的代码是LinkMovementMethod
public class MyLinkMovementMethod extends LinkMovementMethod {
private static LinkMovementMethod sInstance;
public static MovementMethod getInstance() {
if (sInstance == null)
sInstance = new MyLinkMovementMethod();
return sInstance;
}
@Override
public boolean onTouchEvent(TextView widget, Spannable buffer, MotionEvent event) {
int action = event.getAction();
if (action == MotionEvent.ACTION_UP ||
action == MotionEvent.ACTION_DOWN ||
action == MotionEvent.ACTION_MOVE) {
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) {
switch (action){
case MotionEvent.ACTION_UP:
link[0].onClick(widget);
buffer.setSpan(new BackgroundColorSpan(Color.TRANSPARENT),
buffer.getSpanStart(link[0]), buffer.getSpanEnd(link[0]),
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
Selection.removeSelection(buffer);
break;
case MotionEvent.ACTION_DOWN:
buffer.setSpan(new BackgroundColorSpan(Color.GRAY),
buffer.getSpanStart(link[0]), buffer.getSpanEnd(link[0]),
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
Selection.setSelection(buffer,
buffer.getSpanStart(link[0]),
buffer.getSpanEnd(link[0]));
break;
case MotionEvent.ACTION_MOVE:
buffer.setSpan(new BackgroundColorSpan(Color.TRANSPARENT),
buffer.getSpanStart(link[0]), buffer.getSpanEnd(link[0]),
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
Selection.removeSelection(buffer);
break;
}
return false;
} else {
Selection.removeSelection(buffer);
return false;
}
}
// return super.onTouchEvent(widget, buffer, event);
return false;
}
}求大神救救孩子，这是什么原因啊？
