My codename app has master/detail layout.
A TableLayout is used for that, in landscape mode.
It is used also in portrait mode with different proportions.
If the app starts in landscape mode, the master and the detail are visible,
and subsequent orientation changes are handled correctly and the user
interface is succesfully reconstructed.
If the app starts in portrait mode, only the master is visible by design
(that's OK) but after the orientation change the user interface is not
reconstructed completely
because
the master is just at full size, while the detail is not reconstructed.
This is the code of a method that is called at startup and when orientation
changes:
private void setContainers()
{
mainEditingContainer.remove();
//these lines are to handle fab correctly
if (fabBoundContainer!=null) fabBoundContainer.remove();
if (fabFirstTime)
{fabBoundContainer=fab.bindFabToContainer(itemListContainer);}
//mainForm.setLayout(BoxLayout.x()); not useful to reset the TableLayout
//the issue is present also without these revalidations
mainEditingContainer.revalidate();
editingContainer.revalidate();
fabBoundContainer.revalidate();
mainForm.revalidate();
if (isPortrait() && conditions) //not relevant here
{
new EditingForm(appData,myData,mainForm,editingContainer,other
parameters).show();
}
if (isPortrait() && !(conditions)) { // only the master in this mode
//tl=new TableLayout(1,2); not useful
//mainForm.setLayout(tl); not useful
mainForm.add(tl.createConstraint().heightPercentage(100).widthPercentage((int)
(1 * 100)), fabBoundContainer);
}
if(isTablet() && !isPortrait() ) { //master-detail in landscape mode
//tl=new TableLayout(1,2); not useful
//mainForm.setLayout(tl); not useful
mainForm.add(tl.createConstraint().heightPercentage(100).widthPercentage((int)
(leftContainerRatio * 100)), fabBoundContainer).add(mainEditingContainer);
}
mainEditingContainer.revalidate();
editingContainer.revalidate();
fabBoundContainer.revalidate();
mainForm.revalidate();
if (fabFirstTime) fabFirstTime=false;
}
Some commented lines are with some tentative workaround but not successful.
What's wrong? How can I achieve the complete reconstruction of UI in
landscape mode, when the app is started in portrait and then rotates?
I remind you that if the app starts in landscape mode, there are no issues
at any subsequent device rotation (just a BrowserComponent is not resizing,
this will be addressed separately).
Thanks in avance
