}
它将在editText中创建带有文本的Spans但我想删除span在该范围内点击删除按钮。我为它创建了代码“tv.setOnTouchListener(new OnTouchListener(){................”在createContactTextView函数中,但它不起作用。 }

将ImageSpan和ClickableSpan设置为相同的开始和结束位置。
sb.setSpan(new ImageSpan(bd),startSpan ,endSpan , Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
sb.setSpan(new ClickableSpan() {
@Override
public void onClick(View widget) {
// DeleteHere
}
}, startSpan , endSpan , Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
同时删除你的touchlistener,它将无法正常工作!现在将LinkMovement设置为您的edittext。
editText.setMovementMethod(LinkMovementMethod.getInstance());
