HI! I have a relative layout which I am creating programmatically:
RelativeLayout layout = new RelativeLayout( this );
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
Now I have two buttons which I want to add in this relative layout. But the problem is both buttons are being shown on the left of the RelatiiveLayout overlapping on each other.
buttonContainer.addView(btn1);
buttonContainer.addView(btn2);
Now I want to know how can I programmatically set the the android:layout_alignParentRight="true
" or android:layout_toLeftOf="@id/btn"
attribute of buttons as we do in the xml?
regards FAS

You can access any LayoutParams from code using View.getLayoutParams. You just have to be very aware of what LayoutParams your accessing. This is normally achieved by checking the containing ViewGroup if it has a LayoutParams inner child then that's the one you should use. In your case it's RelativeLayout.LayoutParams. You'll be using RelativeLayout.LayoutParams#addRule(int verb) and RelativeLayout.LayoutParams#addRule(int verb, int anchor)
ReplyDeleteYou can get to it via code:
RelativeLayout.Layoutparams params = (RelativeLayout.LayoutParams)button.getLayoutParams();
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
params.addRule(RelativeLayout.LEFT_OF, R.id.id_to_be_left_of);
button.setLayoutParams(params); //causes layout update
you need to create and id for the
ReplyDeletebuttons you need to refference:
btn1.setId(1);
you can use the params variable to
add parameters to your layout, i
think the method is addRule, check
out the android java docs for this
LayoutPArams object.
