(#) Missing accessibility label !!! WARNING: Missing accessibility label This is a warning. Id : `LabelFor` Summary : Missing accessibility label Severity : Warning Category : Accessibility 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/LabelForDetector.kt) 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/LabelForDetectorTest.kt) Copyright Year : 2012 Editable text fields should provide an `android:hint` or, provided your `minSdkVersion` is at least 17, they may be referenced by a view with a `android:labelFor` attribute. When using `android:labelFor`, be sure to provide an `android:text` or an `android:contentDescription`. If your view is labeled but by a label in a different layout which includes this one, just suppress this warning from lint. !!! Tip This lint check has an associated quickfix available in the IDE. (##) Example Here is an example of lint warnings produced by this check: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text res/layout/labelfororhint_empty_hint.xml:11:Warning: Empty android:hint attribute [LabelFor] android:hint="" --------------- res/layout/labelfororhint_empty_hint.xml:21:Warning: Empty android:hint attribute [LabelFor] android:hint="" --------------- res/layout/labelfororhint_empty_hint.xml:29:Warning: Empty android:hint attribute [LabelFor] android:hint="" --------------- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Here is the source file referenced above: `res/layout/labelfororhint_empty_hint.xml`: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~xml linenumbers <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <EditText android:id="@+id/editText1" android:layout_width="match_parent" android:layout_height="wrap_content" android:ems="10" android:hint="" android:inputType="textPersonName"> <requestFocus/> </EditText> <AutoCompleteTextView android:id="@+id/autoCompleteTextView1" android:layout_width="match_parent" android:layout_height="wrap_content" android:ems="10" android:hint="" android:text="AutoCompleteTextView"/> <MultiAutoCompleteTextView android:id="@+id/multiAutoCompleteTextView1" android:layout_width="match_parent" android:layout_height="wrap_content" android:ems="10" android:hint="" android:text="MultiAutoCompleteTextView"/> </LinearLayout> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ You can also visit the [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/LabelForDetectorTest.kt) for the unit tests for this check to see additional scenarios. The above example was automatically extracted from the first unit test found for this lint check, `LabelForDetector.testWithEmptyHint`.

(##) Suppressing You can suppress false positives using one of the following mechanisms: * Adding the suppression attribute `tools:ignore="LabelFor"` 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"?> <EditText xmlns:tools="http://schemas.android.com/tools" tools:ignore="LabelFor" ...> ... </EditText> ``` * 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="LabelFor" 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 'LabelFor' } ``` In Android projects this should be nested inside an `android { }` block. * For manual invocations of `lint`, using the `--ignore` flag: ``` $ lint --ignore LabelFor ...` ``` * Last, but not least, using baselines, as discussed [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
