无法使用Android可访问性服务在WhatsApp EditText中编辑文本

Question

当我们与图像一起发送文本时，我正在尝试在WhatsApp中的EditText中编辑文本。然后通过单击Android可访问性服务单击“发送”按钮将其发送。但是问题在于，EditText中的文本已修改，但是在单击“发送”按钮时，旧文本与图像一起发送。对此的任何帮助将不胜感激。谢谢。

class WhatsappAccessibilityService : AccessibilityService() {

override fun onAccessibilityEvent(event: AccessibilityEvent?) {
    val nodeInfo = event?.source ?: return
    val editMessageNodeList =
        nodeInfo.findAccessibilityNodeInfosByViewId("com.whatsapp:id/caption")
   

    if (editMessageNodeList.isEmpty()) {
        return
    }
    for (editMessage in editMessageNodeList) {
        if (editMessage.className.equals("android.widget.EditText")) {
             val message = editMessage.text.toString()
            val suffix: String = "some text"
            if (message.endsWith(suffix)) {
                val bundle = Bundle()
                val newMessage = message.replace(suffix, "")
                bundle.putString(
                    AccessibilityNodeInfoCompat.ACTION_ARGUMENT_SET_TEXT_CHARSEQUENCE,
                    newMessage
                )
                editMessage.performAction(
                    AccessibilityNodeInfoCompat.ACTION_SET_TEXT,
                    bundle
                )
            }
            val sendMessageNodeList = nodeInfo.findAccessibilityNodeInfosByViewId("com.whatsapp:id/send")

            for (node in sendMessageNodeList!!) {
                if (!node.isVisibleToUser) {
                    return
                }
                node.performAction(AccessibilityNodeInfo.ACTION_CLICK)
                try {
                    Thread.sleep(700)
                    performGlobalAction(GLOBAL_ACTION_BACK)
                    Thread.sleep(700)
                    performGlobalAction(GLOBAL_ACTION_BACK)
                } catch (ignored: InterruptedException) {
                    Log.d("TAG", "onAccessibilityEvent: exception $ignored ")
                }
            }
        }
    }
}

override fun onInterrupt() {
    Log.d("TAG", "onInterrupt: ")
}

}
