DisplayMetrics metrics = new DisplayMetrics();
WindowManager wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
wm.getDefaultDisplay().getMetrics(metrics);
final float height = metrics.heightPixels;

EditText edittext = new EditText(this);

edittext.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,(int) (height/2)));

private EditText createEditText()
{
    final LayoutParams lparams = new LayoutParams(50,30); // Width , height
    final EditText edittext = new EditText(this);
    edittext.setLayoutParams(lparams);
    return edittext;
}
