我正在构建具有以下布局的应用程序:
一个RelativeLayout 容器有一个ImageView 子作为其背景,另外两个RelativeLayouts 作为页面的实际内容。
这些视图的规则设置如下:
// Define rules and params for views in the container
ImageView backgroundImg = new ImageView(this);
RelativeLayout.LayoutParams lpImg = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
lpImg.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
backgroundImg.setImageResource(R.drawable.baggrund_smartphones_retina);
backgroundImg.setLayoutParams(lpImg);
RelativeLayout mainLayout = (RelativeLayout)findViewById(R.id.fragment_main_layout);
RelativeLayout storeLayout = (RelativeLayout)findViewById(R.id.fragment_store_layout);
RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(screenWidth, LayoutParams.MATCH_PARENT);
RelativeLayout.LayoutParams lp2 = new RelativeLayout.LayoutParams(screenWidth, LayoutParams.MATCH_PARENT);
lp1.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
lp2.addRule(RelativeLayout.RIGHT_OF, R.id.fragment_main_layout);
mainLayout.setLayoutParams(lp1);
storeLayout.setLayoutParams(lp2);
root.removeAllViews();
//Add background first to ensure its in the back
snapView.addInfoPage(backgroundImg);
snapView.addInfoPage(mainLayout);
现在这是我的问题。但是我的 RelativeLayouts 与它们的父级正确对齐,但 ImageView 不是。相反,图像视图是这样的地方:
我究竟做错了什么?
