I went to the official doc page android google official doc, but it seems that they made a serious typo : we have no information about the third argument of the method. So I just wonder if someone already knows how to define this third int argument.
The childMeasuredState
is the value returned by View.getMeasuredState()
. A layout will aggregate its children measured states using View.combineMeasuredStates()
. Here is an example:
int childState = 0;
for (int i = 0; i < count; i++) {
final View child = getChildAt(i);
if (child.getVisibility() != GONE) {
measureTheChild(child);
childState = combineMeasuredStates(childState, child.getMeasuredState());
}
}
In most case however you can simply pass 0 instead. The child state is currently used only to tell whether a View was measured at a smaller size than it would like to have. This information is in turn used to resize dialogs if needed. In your particular case you shouldn't worry about it.
