How to interact with USSD dialog programmatically in android

Question

I want to use USSD dialog which comes after dialing any USSD code say *123# which asks user to enter option number to perform

Answer 1

For interacting with USSD dialog, I used below code.

I used the below code for click event:

List list = nodeInfo.findAccessibilityNodeInfosByText("Send");
for (AccessibilityNodeInfo node : list) {
     node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
}

I used the below code for setText in EditText. This is setText where the current focus is.

AccessibilityNodeInfo nodeInput = nodeInfo.findFocus(AccessibilityNodeInfo.FOCUS_INPUT);
Bundle bundle = new Bundle();        
bundle.putCharSequence(AccessibilityNodeInfo.ACTION_ARGUMENT_SET_TEXT_CHARSEQUENCE,pMPIN);
nodeInput.performAction(AccessibilityNodeInfo.ACTION_SET_TEXT,bundle);
nodeInput.refresh();
