I have LinearLayout inside of DrawerLayout which renders drawer item and views according to layout_weight. I am trying to hide that view programmatically by setting its height to 0 or with View.Visibility - GONE property.
Tried
By setting its Visibilty as GONE it acts as INVISIBLE
By getting its LayoutParams and setting its height to 0. Though it acts as INVISIBLE
ParentLayout : mother.xml

Whenever I tried to fetch the layoutParam using getLayoutParams it returns FrameLayout where its ParentView is LinearLayout.
Using Java :
mDashboardLayout = (LinearLayout)mDrawerInnerRootLayout.findViewById(R.id.activityMotherDrawerDashboardLayout);
LinearLayout.LayoutParams mParams = (LinearLayout.LayoutParams) mDashboardLayout.getLayoutParams();//returns FrameLayout instead where it should return LinearLayout
mDashboardLayout.setVisibility(View.GONE); //it acts as INVISIBILITY
Can anyone enlighten me why it returns FrameLayout instead of LinearLayout Or Why its Visibility changes to INVISIBLE instead of GONE?
Though changing View - Visibility to either GONE
or INVISIBLE
still View is always INVISIBLE. It does accept onClick event. As per SO, I want to completely remove that view. I am able to achieve it using following method.
I am adding View to ParentView hierarchy accordingly programmatically and refreshing the whole layout.
View inflatedDashboardView;
inflatedDashboardView = mInflater.inflate(R.layout.layout_drawer_dashboard, mDrawerInnerRootLayout, false);
mDashboardLayout = (LinearLayout) inflatedDashboardView.findViewById(R.id.activityMotherDrawerDashboardLayout);
mDrawerInnerRootLayout.addView(inflatedDashboardView);
mDrawerInnerRootLayout.forceLayout();
Still I'm not able to understand why InnerView Layout inside of DrawerLayout always return FrameLayout.
