Java Code

@Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub

        super.onCreate(savedInstanceState);
        setContentView(R.layout.item);

        newsLayout =(RelativeLayout)findViewById(R.id.newsLayout);

        LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        RelativeLayout row[] = new RelativeLayout[10];
         TextView text[]= new TextView[10];
        for(int i=0;i<10;i++){

        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

       row[i] = (RelativeLayout) inflater.inflate(R.layout.reuse,null);
       params.setMargins(0, 50, 0, 0);
        newsLayout.addView(row[i],params);

         text[i]= (TextView) row[i].findViewById(R.id.text);
        text[i].setText("AAAAAAA");


        }

Answer 1

You can use LinearLayout instead of RelativeLayout for newsLayout and make the orientation as VERTICAL.

And instead of newsLayout =(RelativeLayout)findViewById(R.id.newsLayout);
write: newsLayout =(LinearLayout)findViewById(R.id.newsLayout);

And rest of the code will be as it is.

This will solve your problem.
