点击右边部分跳转，不影响CheckBox的勾选。

//图标和文字的间隔
    String paddingLeftBlank = "   ";

        chk_agree = inflate.findViewById(R.id.chk_agree);
        SpannableString ss = new SpannableString(paddingLeftBlank + chk_agree.getText());
        ss.setSpan(new UnderlineSpan(), paddingLeftBlank.length() + 2, ss.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        ss.setSpan(new ForegroundColorSpan(getResources().getColor(R.color.ca_blue)), paddingLeftBlank.length() + 2, ss.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        ss.setSpan(new ClickableSpan() {
            @Override
            public void onClick(View view) {
                if (view instanceof TextView)
                    ((TextView) view).setHighlightColor(getResources().getColor(android.R.color.transparent));

                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                    view.cancelPendingInputEvents();
                }
                ToastUtil.showToast("go to license");
            }

            @Override
            public void updateDrawState(TextPaint ds) {
//                super.updateDrawState(ds);
            }
        }, paddingLeftBlank.length() + 2, ss.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        CharSequence cs = TextUtils.expandTemplate("^1", ss);
        chk_agree.setText(cs);
        chk_agree.setMovementMethod(LinkMovementMethod.getInstance());
