Можно ли повторно использовать LayoutPrams с ViewGroup.addView?

Использует ли ViewGroup.addView клоны LayoutParams данные внутри или ссылки на него? Можно ли повторно использовать один и тот же экземпляр LayoutParams с несколькими вызовами addView() с разными представлениями?

В apidoc ничего нет.

WOW

Ответ НЕТ (проверено экспериментально):

public class SymbolPadActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    RelativeLayout.LayoutParams labelParams;

    /*
     * This block to reuse is not working
    labelParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    labelParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
    labelParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
    */


    RelativeLayout mover = new RelativeLayout(this);

    TextView textView;
    for(int leftMargin = 0; leftMargin<3000; leftMargin += 100) {
        for(int topMargin=0; topMargin<800; topMargin += 40) {

            // I can't omit these 3 lines 
            labelParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
            labelParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
            labelParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);

            labelParams.leftMargin = leftMargin;
            labelParams.topMargin = topMargin;

            textView = new TextView(this);
            textView.setText("(" + leftMargin + "," + topMargin + ")");
            mover.addView(textView, labelParams);

        }
    }




    RelativeLayout.LayoutParams moverParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    moverParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
    moverParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
    moverParams.leftMargin = 0;
    moverParams.topMargin = 0;

    RelativeLayout stator = new RelativeLayout(this);
    stator.addView(mover, 0, moverParams);

    setContentView(stator);
