Issue with RelativeLayout when View visibility is View.GONE

Question

I\'ve a RelativeLayout thus:

 // <-- View.VISIBLE OR View.GONE

<         


        

Answer 1

you can do this

<RelativeLayout>
<TextView1/>
<FrameLayout>
  <TextView2/>  // <-- View.VISIBLE OR View.GONE
</FrameLayout>
<TextView3/>
<TextView4/>
</RelativeLayout>

let TextView3 below this FrameLayout which has no background, so if TextView2 is Gone ,it doesn't occupy space.

Answer 2

Forget about INVISIBLE or GONE, use this instead:

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) view.getLayoutParams();

params.height = 0;

params.setMargins(0,0,0,0);

view.setLayoutParams(params);

Answer 3

This answer does not solve your specific problem, but does solve a similar one, so hopefully this will help somebody.

I had a situation where my relative layout did not have the equivalent of your TextView1. So, in my situation, if TextView2 was GONE, then I wanted TextView3 to be aligned with the parent's top. I solved that by adding to TextView3 the attribute android:layout_alignWithParentIfMissing="true". See http://developer.android.com/resources/articles/layout-tricks-efficiency.html.

Unfortunately, I do not see a way to specify an alternate alignment anchor unless it is the parent.

Answer 4

place all textViews under LinearLayout with vertical orientation.

<LinearLayout>
<TextView/>
<TextView/>
<TextView/>
<TextView/>
<TextView/>
<TextView/>
</LinearLayout>

Answer 5

You can place textview 2 and 3 in the LinearLayout and keep the linear layout below textview 1.

Answer 6

why not update the below attribute of TextView3 when you update the visibility of TextView2? (I assume you do this in code)

something like

TextView tv = (TextView) findViewById(R.id.textview3);
RelativeLayout.LayoutParams lp =
    (RelativeLayout.LayoutParams) tv.getLayoutParams();
lp.addRule(RelativeLayout.BELOW, R.id.textview1);
((TextView) view).setLayoutParams(lp);
