Question

I’m adding TextViews and EditTexts to the the UI, but they are overlapping each other. I want them to appear next to each other. What I am missing in this code?

ScrollView sv = new ScrollView(this);
            RelativeLayout ll = new RelativeLayout(this);
            ll.setId(99);
            sv.addView(ll, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
            ll.setBackgroundResource(R.drawable.background);

        for (int i = 0; i < 10 /*Changed the actual value for better Understanding*/; i++) {
            tv = new TextView(this);
            tv.setText("" + (productStr[i]));
            tv.setId(i);
            tv.setTextSize(TypedValue.COMPLEX_UNIT_PX, 18);
            RelativeLayout.LayoutParams lay = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, 
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
            lay.addRule(RelativeLayout.ALIGN_RIGHT, RelativeLayout.TRUE);

            ll.addView(tv, lay);
            et = new EditText(this);
            et.setInputType(InputType.TYPE_CLASS_NUMBER);
            et.setEms(2);
            allEds.add(et);
            et.setId(i);

             RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, 
                     RelativeLayout.LayoutParams.WRAP_CONTENT);
             p.addRule(RelativeLayout.ALIGN_BOTTOM, tv.getId());
            ll.addView(et, p);


        }
        this.setContentView(sv);

There is no need to add extra layouts, you could do it with the RelativeLayout. The code below should layout the TextView and EditText like you want:

        ScrollView sv = new ScrollView(this);
        RelativeLayout ll = new RelativeLayout(this);
        ll.setId(99);
        ll.setBackgroundResource(R.drawable.background);

        sv.addView(ll, new LayoutParams(LayoutParams.FILL_PARENT,
                LayoutParams.FILL_PARENT));
        for (int i = 0; i < 10; i++) {
            tv = new TextView(this);
            tv.setText("" + (productStr[i]));
            tv.setId(1000 + i);
            tv.setTextSize(TypedValue.COMPLEX_UNIT_PX, 18);
            RelativeLayout.LayoutParams lay = new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
            lay.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
            if (i != 0) {
                lay.addRule(RelativeLayout.BELOW, 2000 + i - 1);
            }
            ll.addView(tv, lay);
            et = new EditText(this);
            et.setInputType(InputType.TYPE_CLASS_NUMBER);
            et.setEms(2);
            et.setId(2000 + i);
            RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
            p.addRule(RelativeLayout.RIGHT_OF, tv.getId());
            if (i != 0) {
                p.addRule(RelativeLayout.BELOW, 2000 + i - 1);
            }
            ll.addView(et, p);
        }
        this.setContentView(sv);
