Button clicks, Date not setting when creating new Activity

[kagalenitin]

I created a new Activity and added textbox, button, and dateinline.

My code:
final RowDescriptor textDisabled = RowDescriptor.newInstance("txtLocationDisabled",RowDescriptor.FormRowDescriptorTypeText, "", new Value("Click on Location to Set Pickup Location"));
textDisabled.setDisabled(true);
sectionDescriptor.addRow(textDisabled);

    btnPickupLocation.setOnFormRowClickListener(new OnFormRowClickListener() {
        @Override
        public void onFormRowClick(FormItemDescriptor itemDescriptor) {
            if (textDisabled.getValue().equals("Click on Location Button")) {
                textDisabled.setValue(new Value<String>("Set Pickup Location"));
            }
        }
    });
    sectionDescriptor.addRow(btnPickupLocation);

• Date Inline doesn't open the Date Dialog.

- When I set new date in Date Dialog, it doesn't set the value .

Next,
I then used the SampleFormFragment.java from the controller package and modified it. I am not able to upload the modified text file. I run into same issue. Can someone take a look at it please and let me know what am I doing wrong. Appreciate your help in advance. Also is there any active development happening?
