I want add a array of strings (will be TextView) into two LinearLayout dynamically, when idx even add in first LinearLayout, when odd the second.

I define three members in MainActivity:

LinearLayout first;
LinearLayout second;
LinearLayout now;

and in the for loop of array of strings, do:

if(idx%2==0){
  now=first;
}else{
  now=second;
}

ViewGroup.LayoutParams lparams = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
TextView textView = new TextView(MainActivity.this);
textView.setLayoutParams(lparams);
textView.setText(strings[idx]);
now.addView(textView);

But all TextView go to the first LinearLayout, and the second LinearLayout is empty. Why? I am new in java and android development. Can anyone help? Thank you!
