我在XML文件中添加后发生了此错误：
android:autoLink="phone"
android:linksClickable="true"
答案 0 :(得分：0)
通过替换行来解决问题：
etPhone.setText(extras.getString(Contac tDBmoy.COLUMN_PHONE)); etSite.setText(extras.getString(ContactDBmoy.COLUMN_SITE));
on：
etPhone.setText(extras.get(ContactDBmoy.COLUMN_PHONE).toString()); etSite.setText(extras.get(ContactDBmoy.COLUMN_SITE).toString());
