Android 给dialog添加动画（动画的使用2/setView和setcontentView 的区别）

setView和setcontentView 的区别

方式1 和方式2 的区别

方式1 添加动画  那么就不是作用在整个dialog上面， 而是作用在内部的View  效果为dialog大小不变，内部的View 进行动画

方式2 添加动画，作用的是整个dialog

/**
     * 火车票途径站点
     * @param dialog
     * */
    public static void ShowJingTingDialog(Context context){
        AlertDialog dialog=new AlertDialog.Builder(context).create();
        View view=createListView(context);
/*方式1    dialog.setView(view);
        dialog.show();*/
        
//方式2        dialog.show();
        dialog.setContentView(view);
        JingTingAni(view);
    }
