Android - disposition linéaire multiligne

Question

J'ai besoin d'un multi-ligne de mise en page, qui se comportent comme linéaire horizontal layout, mais quand il n'y a pas assez d'espace pour placer un nouveau widget, il permettrait d'élargir à la ligne suivante, tout comme les mots dans un texte. Widgets être ajoutée au moment de l'exécution, et doit aller avec wrap_content. En fait, il y aurait des boutons.

Il y a tout les widgets avec ce genre de comportement? Ou donner une suggestion sur la façon d'écrire une telle mise en page par moi-même.

Enfin, il devrait ressembler à ceci:

private void populateText(LinearLayout ll, View[] views , Context mContext) { 
    Display display = getWindowManager().getDefaultDisplay();
    ll.removeAllViews();
    int maxWidth = display.getWidth() - 20;

    LinearLayout.LayoutParams params;
    LinearLayout newLL = new LinearLayout(mContext);
    newLL.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
            LayoutParams.WRAP_CONTENT));
    newLL.setGravity(Gravity.LEFT);
    newLL.setOrientation(LinearLayout.HORIZONTAL);

    int widthSoFar = 0;

    for (int i = 0 ; i < views.length ; i++ ){
        LinearLayout LL = new LinearLayout(mContext);
        LL.setOrientation(LinearLayout.HORIZONTAL);
        LL.setGravity(Gravity.CENTER_HORIZONTAL|Gravity.BOTTOM);
        LL.setLayoutParams(new ListView.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        //my old code
        //TV = new TextView(mContext);
        //TV.setText(textArray[i]);
        //TV.setTextSize(size);  <<<< SET TEXT SIZE
        //TV.measure(0, 0);
        views[i].measure(0,0);
        params = new LinearLayout.LayoutParams(views[i].getMeasuredWidth(),
                LayoutParams.WRAP_CONTENT);
        //params.setMargins(5, 0, 5, 0);  // YOU CAN USE THIS
        //LL.addView(TV, params);
        LL.addView(views[i], params);
        LL.measure(0, 0);
        widthSoFar += views[i].getMeasuredWidth();// YOU MAY NEED TO ADD THE MARGINS
        if (widthSoFar >= maxWidth) {
            ll.addView(newLL);

            newLL = new LinearLayout(mContext);
            newLL.setLayoutParams(new LayoutParams(
                    LayoutParams.FILL_PARENT,
                    LayoutParams.WRAP_CONTENT));
            newLL.setOrientation(LinearLayout.HORIZONTAL);
            newLL.setGravity(Gravity.LEFT);
            params = new LinearLayout.LayoutParams(LL
                    .getMeasuredWidth(), LL.getMeasuredHeight());
            newLL.addView(LL, params);
            widthSoFar = LL.getMeasuredWidth();
        } else {
            newLL.addView(LL);
        }
    }
    ll.addView(newLL);
}

La réponse de Sherif était bonne, mais ne traitait pas le cas où il pourrait y avoir des vues supplémentaires de chaque côté de LinearLayout en question. J'ai mis à jour et nettoyé le code pour gérer ce cas:

 /**
 * Copyright 2011 Sherif 
 * Updated by Karim Varela to handle LinearLayouts with other views on either side.
 * @param linearLayout
 * @param views : The views to wrap within LinearLayout
 * @param context
 * @param extraView : An extra view that may be to the right or left of your LinearLayout.
 * @author Karim Varela

private void populateViews(LinearLayout linearLayout, View[] views, Context context, View extraView)
{
    extraView.measure(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

    // kv : May need to replace 'getSherlockActivity()' with 'this' or 'getActivity()'
    Display display = getSherlockActivity().getWindowManager().getDefaultDisplay();
    linearLayout.removeAllViews();
    int maxWidth = display.getWidth() - extraView.getMeasuredWidth() - 20;

    linearLayout.setOrientation(LinearLayout.VERTICAL);

    LinearLayout.LayoutParams params;
    LinearLayout newLL = new LinearLayout(context);
    newLL.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
    newLL.setGravity(Gravity.LEFT);
    newLL.setOrientation(LinearLayout.HORIZONTAL);

    int widthSoFar = 0;

    for (int i = 0; i < views.length; i++)
    {
        LinearLayout LL = new LinearLayout(context);
        LL.setOrientation(LinearLayout.HORIZONTAL);
        LL.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.BOTTOM);
        LL.setLayoutParams(new ListView.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

        views[i].measure(0, 0);
        params = new LinearLayout.LayoutParams(views[i].getMeasuredWidth(), LayoutParams.WRAP_CONTENT);
        params.setMargins(5, 0, 5, 0);

        LL.addView(views[i], params);
        LL.measure(0, 0);
        widthSoFar += views[i].getMeasuredWidth();
        if (widthSoFar >= maxWidth)
        {
            linearLayout.addView(newLL);

            newLL = new LinearLayout(context);
            newLL.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
            newLL.setOrientation(LinearLayout.HORIZONTAL);
            newLL.setGravity(Gravity.LEFT);
            params = new LinearLayout.LayoutParams(LL.getMeasuredWidth(), LL.getMeasuredHeight());
            newLL.addView(LL, params);
            widthSoFar = LL.getMeasuredWidth();
        }
        else
        {
            newLL.addView(LL);
        }
    }
    linearLayout.addView(newLL);
}
