RelativeLayout对齐/定位不起作用

Question

I've had a look around, and not been able to find a fix to this problem. Yes it is something that has been asked before, but none of the solutions I've found has corrected my problem.
So basically, my problem is that I need two views to align to the right of their container, one next to the other. I can't stop them from overlapping however.

RelativeLayout.LayoutParams param = new RelativeLayout.LayoutParams((int) (screenWidth*0.30), LayoutParams.WRAP_CONTENT);
param.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
newSpinner.setLayoutParams(param);
newSpinner.setId(-101);

param = new RelativeLayout.LayoutParams((int) (screenWidth*0.10), LayoutParams.WRAP_CONTENT);
param.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
param.addRule(RelativeLayout.LEFT_OF, newSpinner.getId());
newButton.setLayoutParams(param);

The above code results in this: http://i.imgur.com/o1GlZLV.png

param.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);

While removing the above line results in this: http://i.imgur.com/25vlmrw.png

So what's the fix?

Answer 1

You are using the same object 'param' for both spinner and button. Try using like param1 and param2 for each in the first place. Secondly try using

param.addRule(RelativeLayout.ALIGN_PARENT_LEFT); for one item and param.addRule(RelativeLayout.ALIGN_PARENT_RIGHT); for the other to avoid overlapping.

Also try this solution. Create a relative layout with param.addRule(RelativeLayout.ALIGN_PARENT_RIGHT); and then add spinner and button in this relative layout, use ALIGN_PARENT_RIGHT for one item and LEFT_OF for the other. Also make sure to use the appropriate width of the items so that they should not overlap

Answer 2

Remove: param.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);

From newButton.
