ViewPager 加载图片

instantiateItem  方法里面写上

ImageView img = new ImageView(context);
img.setImageResource(ingID.get(position));
container.addView(img);

 

Fragment 静态传值

public static FragmentEmpty newInstance(String text){
    FragmentEmpty fragment = new FragmentEmpty();
    Bundle bundle = new Bundle();
    bundle.putString("param",text);
    fragment.setArguments(bundle);
    return fragment;
}

fragments.add(new FragmentOne());
for (int i = 1; i < titles.size(); i++) {
    FragmentEmpty instance = FragmentEmpty.newInstance(titles.get(i));
    fragments.add(instance);
}
