How to hide linearlayout from java code?

Question

I want to hide the linear layout, so I used

LinearLayout mainLayout=(LinearLayout)this.findViewById(R.id.mainLayout); mainLayout.setVisibility(2); 

but why doesn't it hide ?? !!!

Answer 1

Using:

 mainLayout.setVisibility(LinearLayout.GONE); 

Answer 2

You can also set the visibility in your .xml layout if you want it to be hidden when your application first starts. android:visibility="gone" should do the trick. Thus, it is hidden from the very beginning when the layout is initialized by your application.

Answer 3

The constant value used is incorrect. This should be 8 for GONE. 4 for INVIVIBLE and 0 for VISIBLE.

Check View description from developer site.

And this link .

Answer 4

You can also use LinearLayout. INVISIBLE

The difference is ( Documentation for Android ):

View.GONE - This view is invisible, and does not occupy a space for the layout.

View.INVISIBLE This view is invisible, but it still takes up space for the layout.

You can choose any based on your design.

Answer 5

Using:

 mainLayout.setVisibility(LinearLayout.INVISIBLE);
