View getId is null Android | view-getid-is-null-android

If you create a button or view programmatically with OnClickListener you can set a tag key before button in parent layout is added.
And get correct button by this tag getTag() instead getId() in OnClickListener etc.


Button button = new Button(getApplicationContext());
int idOfButton = button.getId(); // return -1

button.setTag("my_button");
String sTag = (String) button.getTag(); // return "my_button"
