使用AccessibilityNodeInfo打开和关闭开关

Question

好的，所以我想知道是否可以使用AccessibilityService / AccessibilityNodeInfo打开/关闭android.widget.Switch？这是我当前的代码，它可以点击屏幕上的文字，但它不会打开/关闭开关。

public void onAccessibilityEvent(AccessibilityEvent event) {
    AccessibilityNodeInfo source = event.getSource();

if (source == null) {
        return;
    }

    Log.v(TAG, "Event happened");
    processUI(source);
}   

当然，processUI会执行比较包，文本等所有操作，并将其全部发送到clickScreen，它实际上会点击屏幕。

protected void clickScreen(AccessibilityNodeInfo source, final String text, final String type, final int length)
{
    Log.v(TAG, "Clicking: " + source + " / " + text + " / " + type + " / " + length);
    if (text == null)
    {
        Log.v(TAG, "Text is NULL");
        return;
    }

    List<AccessibilityNodeInfo> list = source.findAccessibilityNodeInfosByText(text);
    for (AccessibilityNodeInfo node : list) {
        Log.i(TAG, "SHOULD BE CLICKING: " + node);
        node.performAction(4);
        node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
    }

    list = source
            .findAccessibilityNodeInfosByText(text);
    for (AccessibilityNodeInfo node : list) {
        Log.i(TAG, "MIGHT BE CLICKING: " + node);
        node.performAction(4);
        node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
    }
}
