android– 以编程方式无法在RelativeLayout中对齐ImageView

我无法将imagevIEw添加到相对布局中.我想将图像添加到我使用relativeLayout动态创建的菜单项列表中.我的所有菜单项都显示正常并且按顺序排列但是当我尝试为每个项目添加图像时,我只得到一个箭头并且它不是垂直居中的.以下是我的代码.

在我的XML文件中

在我的代码中：

private voID buildMenu(String name,int ID) {    String[] menuItems = getResources().getStringArray(pMenus[ID]);    // Get the rel layout from xml    relativeLayout container = (relativeLayout) findVIEwByID(R.ID.pMenu);    int imageID=1;    Typeface tf = Typeface.createFromAsset(this.getAssets(),"mreavesmodot-reg.otf");    for(String menuItem: menuItems) {                   // Defining the layout parameters        relativeLayout.LayoutParams lp = new relativeLayout.LayoutParams(                relativeLayout.LayoutParams.WRAP_CONTENT,relativeLayout.LayoutParams.WRAP_CONTENT);        Styledbutton menuImage = new Styledbutton(this);        menuImage.setBackgroundResource(R.drawable.menu_button);        menuImage.setText(menuItem);        menuImage.setTypeface(tf);        menuImage.setTextSize(19);        menuImage.setpadding(20,0);        menuImage.setTextcolor(color.WHITE);        menuImage.setGravity(Gravity.left | Gravity.CENTER_VERTICAL);        menuImage.setonClickListener(getonClickListener(menuImage,name));        menuImage.setID(imageID);        if(imageID==1) {            lp.addRule(relativeLayout.AliGN_PARENT_top);        } else {            lp.addRule(relativeLayout.BELOW,imageID-1);        }        menuImage.setLayoutParams(lp);        ImageVIEw arrow = new ImageVIEw(this);        arrow.setimageResource(R.drawable.arrow_menu);        arrow.setpadding(0,15,0);        relativeLayout.LayoutParams params = new relativeLayout.LayoutParams( relativeLayout.LayoutParams.WRAP_CONTENT,relativeLayout.LayoutParams.WRAP_CONTENT );        params.addRule(relativeLayout.AliGN_RIGHT,menuImage.getID());        params.addRule(relativeLayout.CENTER_VERTICAL);        arrow.setLayoutParams(params);        container.addVIEw(menuImage);        container.addVIEw(arrow);        imageID++;    }}

params.addRule(relativeLayout.CENTER_VERTICAL);
