(#) Dynamic text should probably be selectable !!! WARNING: Dynamic text should probably be selectable This is a warning. Id : `SelectableText` Summary : Dynamic text should probably be selectable Note : **This issue is disabled by default**; use `--enable SelectableText` Severity : Warning Category : Usability Platform : Android Vendor : Android Open Source Project Feedback : https://issuetracker.google.com/issues/new?component=192708 Since : Initial Affects : Resource files Editing : This check runs on the fly in the IDE editor Implementation : [Source Code](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-checks/src/main/java/com/android/tools/lint/checks/TextViewDetector.java) Tests : [Source Code](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-tests/src/test/java/com/android/tools/lint/checks/TextViewDetectorTest.java) Copyright Year : 2012 If a `` is used to display data, the user might want to copy that data and paste it elsewhere. To allow this, the `` should specify `android:textIsSelectable="true"`. This lint check looks for TextViews which are likely to be displaying data: views whose text is set dynamically. !!! Tip This lint check has an associated quickfix available in the IDE.

The above example was automatically extracted from the first unit test found for this lint check, `TextViewDetector.testBasic`.

(##) Suppressing You can suppress false positives using one of the following mechanisms: * Adding the suppression attribute `tools:ignore="SelectableText"` on the problematic XML element (or one of its enclosing elements). You may also need to add the following namespace declaration on the root element in the XML file if it's not already there: `xmlns:tools="http://schemas.android.com/tools"`. ```xml <?xml version="1.0" encoding="UTF-8"?> <TextView xmlns:tools="http://schemas.android.com/tools" tools:ignore="SelectableText" ...> ... </TextView> ``` * Using a special `lint.xml` file in the source tree which turns off the check in that folder and any sub folder. A simple file might look like this: ```xml <?xml version="1.0" encoding="UTF-8"?> <lint> <issue id="SelectableText" severity="ignore" /> </lint> ``` Instead of `ignore` you can also change the severity here, for example from `error` to `warning`. You can find additional documentation on how to filter issues by path, regular expression and so on [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html). * In Gradle projects, using the DSL syntax to configure lint. For example, you can use something like ```gradle lintOptions { disable 'SelectableText' } ``` In Android projects this should be nested inside an `android { }` block. * For manual invocations of `lint`, using the `--ignore` flag: ``` $ lint --ignore SelectableText ...` ``` * Last, but not least, using baselines, as discussed [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
