[android help] How to align view elements in Relativelayout dynamically through code in Android?



layout.addView(cb1);

lp.addRule(RelativeLayout.BELOW,cb1.getId());
cb2.setLayoutParams(lp);
layout.addView(cb2);

lp.addRule(RelativeLayout.BELOW,cb2.getId());
cb3.setLayoutParams(lp);
layout.addView(cb3);


Thanks man this helped me a lot


I guess you are wrong at the point that you are using "lp" as the layout parameters for both cb2 and cb3(you can't add the same rule "RelativeLayout.BELOW" to same layoutparameters object "lp" again and again). Use lp for cb2 and lp2 for cb3 and create like this



RelativeLayout layout = new RelativeLayout(this);

CheckBox cb1 = new CheckBox(this);
cb1.setId(1);
cb1.setText("A");

CheckBox cb2 = new CheckBox(this);
cb2.setId(2);
cb2.setText("B");

CheckBox cb3 = new CheckBox(this);
cb3.setId(3);
cb3.setText("C");

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);
layout.setLayoutParams(lp);

layout.addView(cb1);

lp.addRule(RelativeLayout.BELOW,cb1.getId());
cb2.setLayoutParams(lp);
layout.addView(cb2);

RelativeLayout.LayoutParams lp2 = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);//important

lp2.addRule(RelativeLayout.BELOW,cb2.getId());//important
cb3.setLayoutParams(lp2);//important
layout.addView(cb3);


I think this will work.
