Question

I am creating button on runtime like below…

    Button newCategoryButton = new Button(this);   
    newCategoryButton.setText(catName);
    newCategoryButton.setWidth(30);
    newCategoryButton.setBackgroundResource(R.drawable.bnt);     

    LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT,     LayoutParams.WRAP_CONTENT);

    ll.addView(newCategoryButton, lp);

But my problem is that it disappear when I back from that activity.

I want this permanent. And another problem is that how to set this button below on other button??

Answer 1

 LinearLayout.LayoutParams  layoutParams;
 LinearLayout  ll;
   Button newCategoryButton=new Button(this)
   newCategoryButton.setText("Push Me");
 layoutParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
 ll.addView(view, newCategoryButton);
