android: how to fill a relativelayout ( screen size) with many textviews created dynamically?

Question

I tried to use below code, but the textviews do not change line after it reach the end of screen.

    RelativeLayout ll = (RelativeLayout)findViewById(R.id.viewObj);
    int lastid=0;
    for (int i=0; i<100; i++) {
        String teststr =  " hello ";
        TextView textView2 = new TextView(this); 
        textView2.setId(i+1);
        textView2.setTextSize(30);
        textView2.setBackgroundColor(Color.GREEN);
        textView2.setTextColor(Color.RED);
        textView2.setTypeface(Typeface.MONOSPACE);
        textView2.setText(teststr+String.valueOf(i));  
        if (i>0)
        {
            RelativeLayout.LayoutParams lay = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
            lay.addRule(RelativeLayout.RIGHT_OF, lastid);
            ll.addView(textView2, lay);             
        } else {
            ll.addView(textView2);
        };
        lastid = textView2.getId();

    }

However, I dont know how to determine when to change line. I just keep on putting new textview to the right of the last one created. Can anyone tell me the correct logic to do the task? many thanks.

Easy fix. Switch to a dynamically-created LinearLayout, and set its orientation to vertical:

lay.setOrientation(LinearLayout.VERTICAL);

Ah, I guess I didn't take a good look at your desired output. Well, if that's the case, why not simply append instances of the string to a stringbuilder, and modify the string shown within an EditText view? Lighter-weight that way, too. – Avram Score Apr 02 '13 at 04:16
