Fix part of oppia#5070: Display empty answer message in ratio input i…
…nteraction (oppia#5263) <!-- READ ME FIRST: Please fill in the explanation section below and check off every point from the Essential Checklist! --> ## Explanation <!-- - Explain what your PR does. If this PR fixes an existing bug, please include - "Fixes #bugnum:" in the explanation so that GitHub can auto-close the issue - when this PR is merged. --> Fixes part of oppia#5070 Enables the `submit_answer_button` when the pending answer is empty. Instead of disabling the button, an error message, stating "_**Enter a ratio to continue.**_", is now displayed when the user attempts to submit a blank answer. `RatioInputInteractionViewTestActivity` is added to accessibility-label exemption as this is a test activity. https://github.com/oppia/oppia-android/assets/84731134/33c797c5-af44-4eaa-980e-fafaccf72d26 ## Essential Checklist <!-- Please tick the relevant boxes by putting an "x" in them. --> - [x] The PR title and explanation each start with "Fix #bugnum: " (If this PR fixes part of an issue, prefix the title with "Fix part of #bugnum: ...".) - [x] Any changes to [scripts/assets](https://github.com/oppia/oppia-android/tree/develop/scripts/assets) files have their rationale included in the PR explanation. - [x] The PR follows the [style guide](https://github.com/oppia/oppia-android/wiki/Coding-style-guide). - [x] The PR does not contain any unnecessary code changes from Android Studio ([reference](https://github.com/oppia/oppia-android/wiki/Guidance-on-submitting-a-PR#undo-unnecessary-changes)). - [x] The PR is made from a branch that's **not** called "develop" and is up-to-date with "develop". - [x] The PR is **assigned** to the appropriate reviewers ([reference](https://github.com/oppia/oppia-android/wiki/Guidance-on-submitting-a-PR#clarification-regarding-assignees-and-reviewers-section)). ## For UI-specific PRs only <!-- Delete these section if this PR does not include UI-related changes. --> If your PR includes UI-related changes, then: - Add screenshots for portrait/landscape for both a tablet & phone of the before & after UI changes - For the screenshots above, include both English and pseudo-localized (RTL) screenshots (see [RTL guide](https://github.com/oppia/oppia-android/wiki/RTL-Guidelines)) - Add a video showing the full UX flow with a screen reader enabled (see [accessibility guide](https://github.com/oppia/oppia-android/wiki/Accessibility-A11y-Guide)) - For PRs introducing new UI elements or color changes, both light and dark mode screenshots must be included - Add a screenshot demonstrating that you ran affected Espresso tests locally & that they're passing --------- Co-authored-by: Adhiambo Peres <59600948+adhiamboperes@users.noreply.github.com>
