I have developed a layout to which i want to add multiple copies of the same
child view. the child view is defined in a xml file. To add each child to
its parent i am calling:
ChildView childView = new ChildView (context);
linearLayout.addView(childView ,new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
the constructor of ChildView is as follows:
public ChildView (Context context)
{
super(context);
inflate(context, R.layout.child_view, this);
checkBox = (CheckBox) findViewById(R.id.checkbox);
}
everything is working correctly and i can manipulate each checkbox
correctly. however when the phone is rotated the restored state for each
checkbox is the state of the last child. in this particular case I don't
actually need to save the state as it can be restored from elsewhere so have
managed to work around the problem by adding
protected void dispatchRestoreInstanceState(SparseArray<Parcelable>
container)
{
dispatchThawSelfOnly(container);
}
to ChildView. however if i want to do something similar in future and do
need to save the state what are my options? do I have to handle save and
restore of state in ChildView? do i need to somehow assign a unique id to
each checkbox (how would these be generated?).
