Question

我有一个recycleview，里面有10个以上的项目。因为它有超过10个项目，它一次只显示4个项目。问题来自TalkBack，我想在列表中使用左/右拖动动作进行迭代但是在4.项目焦点转到布局上的另一个视图组件之后。如何使用Talkback迭代所有的recycleview项目？

编辑：我使用自己的可访问性委托：

mRecyclerView.setAccessibilityDelegate(mAccessibilityDelegate);


public class AccessibilityDelegate extends View.AccessibilityDelegate {

private Assistant mAssistant;

public AccessibilityDelegate(Assistant assistant)
{
    mAssistant = assistant;
}

@Override
public void sendAccessibilityEvent(View host, int eventType) {
    if(!mAssistant.isSpeaking() && mAssistant.isRecognizerAvailable())
    {
        super.sendAccessibilityEvent(host, eventType);
    }
}

@Override
public boolean performAccessibilityAction(View host, int action, Bundle args) {
    if(!mAssistant.isSpeaking() && mAssistant.isRecognizerAvailable())
    {
        return super.performAccessibilityAction(host, action, args);
    }

    return false;
}

@Override
public void sendAccessibilityEventUnchecked(View host, AccessibilityEvent event) {
    super.sendAccessibilityEventUnchecked(host, event);
}

@Override
public boolean dispatchPopulateAccessibilityEvent(View host, AccessibilityEvent event) {
    return super.dispatchPopulateAccessibilityEvent(host, event);
}

@Override
public void onPopulateAccessibilityEvent(View host, AccessibilityEvent event) {
    super.onPopulateAccessibilityEvent(host, event);
}

@Override
public void onInitializeAccessibilityEvent(View host, AccessibilityEvent event) {
    super.onInitializeAccessibilityEvent(host, event);
}

@Override
public void onInitializeAccessibilityNodeInfo(View host, AccessibilityNodeInfo info) {
    super.onInitializeAccessibilityNodeInfo(host, info);
}

@Override
public boolean onRequestSendAccessibilityEvent(ViewGroup host, View child, AccessibilityEvent event) {
    return super.onRequestSendAccessibilityEvent(host, child, event);
}

@Override
public AccessibilityNodeProvider getAccessibilityNodeProvider(View host) {
    return super.getAccessibilityNodeProvider(host);
}

}

Answer 1

经过几次试验后，我发现了问题。

要覆盖RecycleView的辅助功能，请扩展RecyclerViewAccessibilityDelegate。

java -version

此外，如果你想禁用像“显示第1项第1项”这样的宣告，只需注释掉super.sendAccessibilityEventUnchecked（主持人，事件）

File > Project Structure > JDK Location

}

Android使用TalkBack迭代RecycleView的隐藏项目
