    LayoutParams.WRAP_CONTENT);  
    params2.addRule(RelativeLayout.ALIGN_PARENT_RIGHT); 
    txt2.setLayoutParams(params2);  
    txt2.setText("obj");
    txt2.setId(1001);  
    
    RelativeLayout layout1 = new RelativeLayout(this);  
    layout1.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));  
    layout1.addView(txt1);
