修改无障碍焦点秩序 [英] Modify accessibility focus order

问题描述

是否有可能改变无障碍焦点顺序？举例来说，如果我有3次并肩，与IDS厂景，视图2和视图3，有一个简单的方法，使无障碍重点去VIEW3当用户直接从厂景挥笔？

Is it possible to change the accessibility focus order? For example, if I have 3 views side by side, with ids view1, view2, and view3, is there a simple way to make the accessibility focus go to view3 when the user swipes right from view1?

下面是我已经试过：

我有一个线性布局以下。

I have the following in a linear layout.

<ImageView
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:id="@+id/imageView"
    android:focusable="true"
    android:nextFocusUp="@+id/imageView3"
    android:nextFocusDown="@+id/imageView3"
    android:nextFocusRight="@+id/imageView3"
    android:nextFocusLeft="@+id/imageView3"
    android:nextFocusForward="@+id/imageView3"
    android:src="@drawable/ic_launcher"/>

<ImageView
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:id="@+id/imageView2"
    android:focusable="true"
    android:src="@drawable/ic_launcher"/>

<ImageView
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:id="@+id/imageView3"
    android:focusable="true"
    android:nextFocusUp="@+id/imageView2"
    android:nextFocusDown="@+id/imageView2"
    android:nextFocusRight="@+id/imageView2"
    android:nextFocusLeft="@+id/imageView2"
    android:nextFocusForward="@+id/imageView2"
    android:src="@drawable/ic_launcher"/>

然后，我推出这个和地点的无障碍重点放在第一ImageView的。当向右滑动，移动到下一个项目，我希望它的无障碍焦点移到imageView3，而是它去imageView2。

Then, I launch this and place accessibility focus on the first imageView. Upon swiping right to move to the next item, I expect it to move accessibility focus to imageView3, but instead it goes to imageView2.

推荐答案

看起来你现在可以设置API的话语提示遍历顺序22+！因此，code会是这个样子：

Looks like you can now set the TalkBack traversal order for API 22+! So the code would look something like this:

<ImageView
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:id="@+id/imageView"
    android:focusable="true"
    android:src="@drawable/ic_launcher"/>

<ImageView
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:id="@+id/imageView2"
    android:focusable="true"
    android:accessibilityTraversalAfter="@id/ImageView3"
    android:src="@drawable/ic_launcher"/>

<ImageView
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:id="@+id/imageView3"
    android:focusable="true"
    android:accessibilityTraversalAfter="@id/ImageView"
    android:src="@drawable/ic_launcher"/>
