Root cause: A long content textview shows the accessibility service info and learn more link. User cannot double click to open help link. They need to swipe up and right to pops up dialog to move to next page. But, the dialog show the "Learn more", it is not clear for user to idendify what the link page. Solution: Add another textview to show the "Learn more" and provides more clear content description for this link. Also, user just need to double click to activate it. Bug: 188603037 Test: make RunSettingsRoboTests -j52 ROBOTEST_FILTER=AccessibilityFooterPreferenceTest Change-Id: Ia9a56f11bbd235ae3a698fcb2e1a2fcff64ef940
