When trying to get xml layout in activity on setContentView(R.layout. ) ==not able to find the layout
=> Reason and solution
1) the layout might some error so instead of repairing it delete and again create it and clean project. ( Specially if you are not getting particular layout)
2) when we are accessing layout to set in Activity and not able to find any layout then its an issue of selection for proper package ==> setContentView(R.) = after pressing r. when we select layout then select it carefully because it shows default 1) layout-android.R and 2)layout-your package name.R so always select layout with your package
layout ==== 2)layout-your package name.R then you can see all layout
=== setContentView(R.layout.xml_layout)

Solution:=>
String name=”Pankaj”;
Check value in arraylist using => arrayList.indexOf()
and take out the position of value from arraylist.=>
int pos= arrayList.indexOf(name);
Set Position in Spinner :=>
spinner.setSelection(pos);
-------------------------------------------------
int pos= arrayList.indexOf(name);
spinner.setSelection(pos);
Suppose we are using Same XML layout for different activity with minimum difference Then we need to hide the unused content..
WE can do it runtime in activity in code:==>
Button Delete;
Delete.setVisibility(View.GONE)
Spinner name;
name.setVisibility(View.GONE);
In this code i have used two linear layout in Horizontal Scrollview.=>[
first Outerlinear layout(orientation:vertical) contain==>[ inner linear layout(orientation:horizontal) which includes textview’s which work as header and scroll with listview.] that listview is in outer layout after closing inner layout.]

use android:layout_weight=”” to fix the component on layout for each screen size.
//It will helpful in case if we want to refresh the page
Intent intent = getIntent();
