  • visible - This means visible and it takes space.
  • invisible- This means invisible and it takes space.
  • gone- This means invisible and it DOESN'T takes space.

Use it as follows:

Visible tag in XML

android:visibility="visible"

Visible code in java

view.setVisibility(View.VISIBLE);

Invisible tag in XML

android:visibility="invisible"

Invisible code in java

view.setVisibility(View.INVISIBLE);

Gone tag in XML

android:visibility="gone"

Gone tag in java

view.setVisibility(View.GONE);

As what @Tim suggested,you can always change the layout parameters for the elements not just set it's visibility to VISIBLE or GONE

Here the sample. Assume checkBox is clicked

checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if(isChecked){  
                buttonID.setVisibility(View.GONE);
             }
            else{
                buttonID.setVisibility(View.VISIBLE); 
                // now settings the new parameters
                AbsoluteLayout.LayoutParams params = ((AbsoluteLayout.LayoutParams) buttonID.getLayoutParams());
                params.x = 100; // the new value
                params.y = 100; // the new value
                buttonID.setLayoutParams(params);
            }
    });

you should use View.GONE instead of View.INVISIBLE
