android - Jetpack Compose Focus Order with Talkback

Question

按照文档: https://developer.android.com/reference/kotlin/androidx/compose/ui/focus/package-summary#(androidx.compose.ui.Modifier).focusOrder(kotlin.Function1)

我想为 Column 设置自定义焦点顺序。

我已经按照文档为每个项目设置了不同的焦点请求者，并指定要关注的项目 next，但似乎 Talkback 忽略了我的元素的焦点顺序。

这是一个例子:

                val focusRequesters = remember { List(4) { FocusRequester() } }
                Column {
                    Text("Line 1",
                        Modifier
                            .focusOrder(focusRequesters[0]) {
                                next = focusRequesters[2]
                                down = focusRequesters[2]
                                right = focusRequesters[2]
                            }
                            .focusable())
                    Text("Line 2",
                        Modifier
                            .focusOrder(focusRequesters[1]) {
                                next = focusRequesters[0]
                                down = focusRequesters[0]
                                right = focusRequesters[0]
                            }
                            .focusable())
                    Text("Line 3",
                        Modifier
                            .focusOrder(focusRequesters[2]) {
                                next = focusRequesters[3]
                                down = focusRequesters[3]
                                right = focusRequesters[3]
                            }
                            .focusable())
                    Text("Line 4",
                        Modifier
                            .focusOrder(focusRequesters[3]) {
                                next = focusRequesters[1]
                                down = focusRequesters[1]
                                right = focusRequesters[1]
                            }
                            .focusable())
                }

尝试了 next、down、right 和每个单独的组合，但似乎没有任何改变 Accessibility 遍历顺序。

Answer 1

如果您使用 LocalFocusManager 更改它，焦点顺序将被考虑在内，如下所示:

LocalFocusManager.current.moveFocus(FocusDirection.Next)

但这与可访问性无关。似乎 android:accessibilityTraversalAfter 对应物在 Compose 中尚不可用，请关注 this issue了解详情。
